When the left ventricle can no longer provide adequate forward flow, patients may develop low cardiac output, congestion, end-organ dysfunction, repeated hospitalizations, and reduced functional capacity. A Left Ventricular Assist Device (LVAD) is one of the major tools in \u201cadvanced heart failure\u201d care because it can provide sustained circulatory support when medications and conventional devices are not enough.<\/p>\n\n\n\n<p>For learners, LVAD care is clinically important because it connects core physiology to real-world decision-making:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hemodynamics and perfusion:<\/strong> LVAD therapy changes how clinicians think about cardiac output, preload, afterload, and the relationship between left- and right-sided heart function.<\/li>\n<li><strong>Treatment planning:<\/strong> LVADs often sit on a pathway that includes optimization of guideline-directed medical therapy, device therapy (e.g., cardiac resynchronization therapy when indicated), evaluation for heart transplantation, and palliative goals-of-care discussions.<\/li>\n<li><strong>Risk assessment:<\/strong> Not every patient with severe heart failure benefits from LVAD implantation; careful selection considers comorbidities, frailty, psychosocial support, bleeding and thrombotic risks, and the likelihood of right ventricular failure after implantation.<\/li>\n<li><strong>Complication recognition:<\/strong> LVADs introduce new clinical problems (e.g., bleeding, thrombosis, infection) that can present subtly and require specific diagnostic thinking.<\/li>\n<\/ul>\n\n\n\n<p>Understanding LVADs helps trainees interpret common bedside questions: Why might a patient have a weak or absent palpable pulse? Why are anticoagulation decisions complex? Why does right ventricular function become central after left-sided support is placed? These are high-yield cardiology concepts that generalize to shock states, mechanical circulatory support, and perioperative cardiac care.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Classification \/ types \/ variants<\/h2>\n\n\n\n<p>LVADs can be categorized in several practical ways. Terminology may vary by clinician and case, but common frameworks include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>By intended duration<\/strong><\/li>\n<li><strong>Temporary (short-term) mechanical circulatory support:<\/strong> Used in acute decompensation or cardiogenic shock as a \u201cbridge to decision\u201d or to stabilize physiology. Some systems are percutaneous or surgically placed and are intended for days to weeks.<\/li>\n<li>\n<p><strong>Durable (long-term) LVAD:<\/strong> Implantable pumps designed for months to years of support in selected patients with advanced heart failure.<\/p>\n<\/li>\n<li>\n<p><strong>By clinical intent<\/strong><\/p>\n<\/li>\n<li><strong>Bridge to transplant (BTT):<\/strong> Support while awaiting heart transplantation.<\/li>\n<li><strong>Destination therapy (DT):<\/strong> Long-term support for patients who are not transplant candidates.<\/li>\n<li><strong>Bridge to recovery:<\/strong> Used when myocardial recovery is possible in selected situations (for example, potentially reversible cardiomyopathies). The likelihood of recovery varies by etiology and patient factors.<\/li>\n<li>\n<p><strong>Bridge to candidacy \/ bridge to decision:<\/strong> Support to allow time for evaluation, rehabilitation, or reversal of potentially modifiable contraindications to transplant.<\/p>\n<\/li>\n<li>\n<p><strong>By pump flow characteristics<\/strong><\/p>\n<\/li>\n<li><strong>Pulsatile-flow (older-generation) devices:<\/strong> Designed to mimic a pulse; less common in contemporary practice.<\/li>\n<li>\n<p><strong>Continuous-flow devices (common in modern durable LVADs):<\/strong> Often axial-flow or centrifugal-flow pumps. Continuous flow can reduce pulse pressure and may make pulse assessment and blood pressure measurement less straightforward.<\/p>\n<\/li>\n<li>\n<p><strong>By configuration<\/strong><\/p>\n<\/li>\n<li><strong>Isolated LVAD support:<\/strong> Supports the left ventricle; right ventricular function must be adequate or supported by other measures.<\/li>\n<li><strong>Biventricular support:<\/strong> When both ventricles require mechanical support (may involve an RVAD, BiVAD configuration, or other approaches). Specific strategies depend on patient anatomy and program protocols.<\/li>\n<\/ul>\n\n\n\n<p>These categories matter because they influence surgical approach, monitoring priorities, anticoagulation strategy, expected complications, and follow-up intensity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Relevant anatomy &amp; physiology<\/h2>\n\n\n\n<p>An LVAD interfaces with core cardiovascular structures and forces clinicians to think carefully about circulation as a closed-loop system.<\/p>\n\n\n\n<p>Key anatomy typically involved includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Left ventricle (LV):<\/strong> The failing LV is the target chamber. LV dilation and reduced contractility (common in heart failure with reduced ejection fraction) can contribute to elevated left-sided filling pressures and pulmonary congestion.<\/li>\n<li><strong>Mitral valve and left atrium:<\/strong> LV unloading can reduce left atrial pressure and pulmonary venous congestion, which may improve dyspnea and exercise tolerance in selected patients.<\/li>\n<li><strong>Aortic valve and ascending aorta:<\/strong> Many durable LVADs deliver blood into the <strong>ascending aorta<\/strong> through an outflow graft. Aortic valve opening frequency may decrease, which can affect valve and aortic root physiology over time.<\/li>\n<li><strong>Right ventricle (RV) and pulmonary circulation:<\/strong> Even though the device supports the LV, the RV must still pump blood through the lungs to fill the LV (or LVAD inflow). RV dysfunction can become a limiting factor after implantation.<\/li>\n<li><strong>Systemic vascular resistance (SVR) and afterload:<\/strong> LVAD flow interacts with afterload. Elevated SVR (e.g., from hypertension or vasoconstriction) can reduce effective forward flow, while low SVR states may create different hemodynamic challenges.<\/li>\n<li><strong>Coronary perfusion and end-organ circulation:<\/strong> Improved systemic perfusion can support kidney and liver function, but perfusion patterns and pulsatility may differ with continuous-flow support.<\/li>\n<\/ul>\n\n\n\n<p>Physiologically, an LVAD can be understood as \u201cbypassing\u201d part of the LV\u2019s workload by moving blood from the LV to the aorta. This changes pressures and volumes throughout the system, not only within the left heart.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Pathophysiology or mechanism<\/h2>\n\n\n\n<p>A Left Ventricular Assist Device provides mechanical circulatory support by <strong>augmenting forward flow<\/strong> from the left side of the heart into the systemic arterial circulation.<\/p>\n\n\n\n<p>A simplified mechanism (durable LVADs in typical configuration) includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Inflow:<\/strong> Blood enters the pump through an inflow cannula positioned in the LV (commonly near the apex).<\/li>\n<li><strong>Pump function:<\/strong> The pump propels blood forward using an internal rotor\/impeller. Most modern durable devices generate <strong>continuous flow<\/strong>, meaning there may be reduced arterial pulsatility.<\/li>\n<li><strong>Outflow:<\/strong> Blood exits through an outflow graft connected to the ascending aorta, increasing systemic blood flow and supporting perfusion of organs.<\/li>\n<\/ul>\n\n\n\n<p>Hemodynamic effects commonly discussed in teaching:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>LV unloading:<\/strong> By drawing blood out of the LV, the device reduces LV end-diastolic volume and pressure, which can lower pulmonary venous pressures and relieve congestion.<\/li>\n<li><strong>Improved cardiac output (effective systemic flow):<\/strong> Total systemic flow becomes a combination of native LV ejection (if any) plus LVAD flow.<\/li>\n<li><strong>Septal position and RV interaction:<\/strong> Aggressive LV unloading can shift the interventricular septum, potentially affecting RV geometry and function. The net RV response varies by baseline RV function, volume status, pulmonary vascular resistance, and device settings.<\/li>\n<li><strong>Pulsatility changes:<\/strong> In continuous-flow support, patients may have a diminished pulse pressure; some may have a weak or intermittently palpable pulse depending on native heart function and aortic valve opening.<\/li>\n<\/ul>\n\n\n\n<p>Because LVADs are mechanical systems working inside a biological circulation, performance depends on multiple variables (preload, afterload, rhythm, RV output, and device settings). Clinical interpretation often integrates bedside assessment with device parameter trends and echocardiography; exact targets vary by protocol and patient factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Clinical presentation or indications<\/h2>\n\n\n\n<p>A Left Ventricular Assist Device is typically considered in advanced heart failure or severe hemodynamic compromise. Common clinical scenarios include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advanced chronic heart failure<\/strong> with severe symptoms despite optimized medical therapy, often with recurrent decompensations and impaired functional capacity.<\/li>\n<li><strong>Bridge to transplant<\/strong> in patients with end-stage heart failure awaiting a donor heart.<\/li>\n<li><strong>Destination therapy<\/strong> in selected patients with advanced heart failure who are not transplant candidates.<\/li>\n<li><strong>Cardiogenic shock<\/strong> or rapidly progressive heart failure where temporary mechanical circulatory support is used to stabilize perfusion and allow time for evaluation (approach varies by center).<\/li>\n<li><strong>End-organ dysfunction from low output<\/strong> (e.g., worsening kidney or liver function) where improved perfusion is a key goal, recognizing that reversibility varies.<\/li>\n<li><strong>Refractory symptoms or intolerance of guideline-directed therapy<\/strong> due to hypotension or renal dysfunction, where mechanical support is part of an advanced therapy pathway.<\/li>\n<\/ul>\n\n\n\n<p>Indications are individualized and typically determined by an advanced heart failure team using clinical status, hemodynamics, comorbidities, and patient goals.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Diagnostic evaluation &amp; interpretation<\/h2>\n\n\n\n<p>LVAD care involves two diagnostic \u201cphases\u201d: <strong>pre-implant evaluation<\/strong> (who is an appropriate candidate) and <strong>post-implant assessment<\/strong> (is the device working well and are complications developing).<\/p>\n\n\n\n<p>Common elements of a pre-implant evaluation include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>History and physical examination<\/strong><\/li>\n<li>Heart failure trajectory (hospitalizations, medication tolerance, functional capacity)<\/li>\n<li>Signs of congestion and low perfusion<\/li>\n<li>Frailty, nutrition, and functional status considerations<\/li>\n<li><strong>Electrocardiogram (ECG):<\/strong> Rhythm, conduction disease, ischemic patterns, prior infarction.<\/li>\n<li><strong>Echocardiography<\/strong><\/li>\n<li>LV size and systolic function<\/li>\n<li>Valvular disease (mitral regurgitation, aortic insufficiency, tricuspid regurgitation)<\/li>\n<li>RV size and function (a key predictor of post-implant course)<\/li>\n<li>Intracardiac thrombus assessment when relevant<\/li>\n<li><strong>Hemodynamic assessment<\/strong> (often with right heart catheterization)<\/li>\n<li>Filling pressures, pulmonary artery pressures, pulmonary vascular resistance<\/li>\n<li>Cardiac output\/index estimation and response to therapy<\/li>\n<li><strong>Laboratory testing<\/strong><\/li>\n<li>Kidney and liver function, electrolytes<\/li>\n<li>Hematologic profile (anemia, thrombocytopenia)<\/li>\n<li>Coagulation profile (important for perioperative planning)<\/li>\n<li>Screening for infection and other comorbidities per protocol<\/li>\n<li><strong>Imaging and specialty assessments<\/strong> as appropriate<\/li>\n<li>Coronary assessment when ischemia is suspected or known<\/li>\n<li>Pulmonary evaluation, vascular imaging, or neurologic evaluation depending on patient factors<\/li>\n<li>Psychosocial assessment and support planning (critical for long-term device management)<\/li>\n<\/ul>\n\n\n\n<p>Post-implant monitoring and interpretation often includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Clinical assessment<\/strong><\/li>\n<li>Perfusion markers (mental status, urine output trends, exercise tolerance)<\/li>\n<li>Congestion assessment (weight trends, edema, jugular venous pressure patterns)<\/li>\n<li>Neurologic checks when indicated given stroke risk<\/li>\n<li><strong>Device parameters (controller readouts)<\/strong><\/li>\n<li>Commonly displayed variables include <strong>pump speed<\/strong>, estimated <strong>flow<\/strong>, <strong>power<\/strong>, and measures of pulsatility (nomenclature varies by device).<\/li>\n<li>Interpretation is trend-based; alarms or parameter shifts prompt assessment of preload status, afterload changes, arrhythmias, cannula position, thrombosis, or device malfunction (varies by protocol).<\/li>\n<li><strong>Blood pressure measurement<\/strong><\/li>\n<li>With continuous-flow devices, standard cuff readings may be less reliable; Doppler-assisted techniques are commonly used in some settings.

A single abnormal value rarely stands alone without context.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Management overview (General approach)<\/h2>\n\n\n\n<p>Management of patients who receive a Left Ventricular Assist Device is multidisciplinary and longitudinal. A high-level approach typically involves:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advanced heart failure optimization before LVAD (when time allows)<\/strong><\/li>\n<li>Maximizing evidence-based heart failure therapies when tolerated<\/li>\n<li>Addressing reversible contributors (ischemia, valvular disease, arrhythmias, iron deficiency\/anemia when relevant)<\/li>\n<li>\n<p>Clarifying goals of care and expected lifestyle changes with device therapy<\/p>\n<\/li>\n<li>\n<p><strong>Patient selection and shared decision-making<\/strong><\/p>\n<\/li>\n<li>Determining whether LVAD is intended as bridge to transplant, destination therapy, or another strategy<\/li>\n<li>Reviewing comorbidities that influence surgical risk and long-term outcomes<\/li>\n<li>\n<p>Assessing the patient\u2019s ability to participate in device care (power management, driveline care, follow-up), typically with caregiver involvement<\/p>\n<\/li>\n<li>\n<p><strong>Implantation and perioperative care<\/strong><\/p>\n<\/li>\n<li>Surgical implantation requires cardiothoracic expertise and intensive postoperative management.<\/li>\n<li>\n<p>Early priorities often include hemodynamic stabilization, RV support as needed, volume management, rhythm control, and careful monitoring for bleeding or thrombosis.<\/p>\n<\/li>\n<li>\n<p><strong>Long-term outpatient management<\/strong><\/p>\n<\/li>\n<li><strong>Antithrombotic therapy:<\/strong> Many LVAD patients require anticoagulation and\/or antiplatelet therapy to reduce pump thrombosis and stroke risk; regimens vary by device type and institutional protocol.<\/li>\n<li><strong>Blood pressure management:<\/strong> Afterload can influence device flow; BP targets and measurement methods vary by center.<\/li>\n<li><strong>Heart failure medications:<\/strong> Some patients continue guideline-directed therapies as tolerated for myocardial and vascular benefits; approach varies by clinician and patient factors.<\/li>\n<li><strong>Device and driveline care:<\/strong> Education on controller use, battery management, and driveline site care is central to reducing complications.<\/li>\n<li><strong>Rehabilitation and functional recovery:<\/strong> Structured activity progression and cardiac rehabilitation principles are often used, tailored to patient capacity and program practices.<\/li>\n<li><strong>Coordination with transplant pathways:<\/strong> For bridge-to-transplant patients, ongoing transplant candidacy assessment continues while on support.<\/li>\n<\/ul>\n\n\n\n<p>Because LVAD therapy changes daily life and introduces specific risks, many programs emphasize consistent follow-up, early reporting of alarms or symptoms, and coordinated care between emergency services and the implanting center (local practices vary).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Complications, risks, or limitations<\/h2>\n\n\n\n<p>Complications are a major part of LVAD education because they often drive readmissions and influence long-term outcomes. Risks can be context-dependent and vary by device generation and patient factors, but commonly discussed issues include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bleeding<\/strong><\/li>\n<li>Gastrointestinal bleeding is a recognized complication in some LVAD populations.<\/li>\n<li>\n<p>Contributing factors may include anticoagulation\/antiplatelet therapy and acquired changes in hemostasis seen with continuous-flow support; exact mechanisms and relative contributions vary.<\/p>\n<\/li>\n<li>\n<p><strong>Thromboembolism and stroke<\/strong><\/p>\n<\/li>\n<li>Both ischemic and hemorrhagic neurologic events can occur.<\/li>\n<li>\n<p>Risk reflects a balance between thrombosis prevention and bleeding risk; management strategies vary by protocol.<\/p>\n<\/li>\n<li>\n<p><strong>Pump thrombosis or device malfunction<\/strong><\/p>\n<\/li>\n<li>May present with alarms, changes in device parameters, hemolysis patterns, heart failure symptoms, or hemodynamic compromise.<\/li>\n<li>\n<p>The diagnostic approach is typically urgent and systematized at experienced centers.<\/p>\n<\/li>\n<li>\n<p><strong>Infection<\/strong><\/p>\n<\/li>\n<li>Driveline infections and deeper device-related infections are clinically important complications.<\/li>\n<li>\n<p>Risk is influenced by skin integrity, trauma at the exit site, hygiene practices, and immune\/host factors.<\/p>\n<\/li>\n<li>\n<p><strong>Right ventricular failure<\/strong><\/p>\n<\/li>\n<li>The RV may fail after LV unloading due to increased venous return demands and altered septal geometry.<\/li>\n<li>\n<p>This can lead to congestion, low LVAD preload, and reduced effective flow.<\/p>\n<\/li>\n<li>\n<p><strong>Arrhythmias<\/strong><\/p>\n<\/li>\n<li>Atrial and ventricular arrhythmias may persist despite LVAD support.<\/li>\n<li>\n<p>Some patients tolerate arrhythmias better with an LVAD than without, but arrhythmias can still reduce filling and effective pump flow.<\/p>\n<\/li>\n<li>\n<p><strong>Aortic valve disease (especially aortic insufficiency)<\/strong><\/p>\n<\/li>\n<li>\n<p>Chronic LVAD support can be associated with changes in aortic valve opening and valve function over time in some patients.<\/p>\n<\/li>\n<li>\n<p><strong>Quality-of-life and logistical limitations<\/strong><\/p>\n<\/li>\n<li>Dependence on external power sources and controller management<\/li>\n<li>Activity modifications related to driveline care and water exposure precautions (specific guidance varies by program)<\/li>\n<li>Psychological stress, caregiver burden, and frequent medical contact<\/li>\n<\/ul>\n\n\n\n<p>Contraindications are individualized; examples of limiting factors may include uncontrolled systemic infection, inability to safely use required antithrombotic therapy, severe irreversible end-organ dysfunction, or insufficient psychosocial support. Final determinations vary by clinician and case.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Prognosis &amp; follow-up considerations<\/h2>\n\n\n\n<p>In appropriately selected patients, a Left Ventricular Assist Device can improve perfusion and functional capacity compared with untreated end-stage heart failure, and it may serve as a bridge to transplantation or as long-term support. Outcomes are heterogeneous and depend on multiple variables, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Underlying heart disease<\/strong> and duration\/severity of heart failure<\/li>\n<li><strong>RV function<\/strong> and pulmonary vascular physiology<\/li>\n<li><strong>Comorbidities<\/strong> (renal dysfunction, liver disease, diabetes, vascular disease, prior stroke, frailty)<\/li>\n<li><strong>Complication burden<\/strong> (bleeding, infection, thrombosis, neurologic events)<\/li>\n<li><strong>Adherence and support system<\/strong> for device management and follow-up<\/li>\n<\/ul>\n\n\n\n<p>Follow-up is typically frequent and multidisciplinary, involving advanced heart failure cardiology, cardiac surgery, anticoagulation management, nursing education, rehabilitation, and sometimes palliative care. The exact schedule and monitoring plan vary by protocol and patient factors, but the overarching goals are to optimize device function, prevent complications, and maintain quality of life.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Left Ventricular Assist Device Common questions (FAQ)<\/h2>\n\n\n\n<p><strong>Q: What does a Left Ventricular Assist Device do, in simple terms?<\/strong><br\/>\nIt helps move blood from the left ventricle into the aorta so the body receives more blood flow. Think of it as assisting a weakened left-sided pump rather than replacing the heart entirely. Many patients still have some native heart function alongside device support.<\/p>\n\n\n\n<p><strong>Q: Is an LVAD the same thing as an artificial heart?<\/strong><br\/>\nNot usually. A Left Ventricular Assist Device supports the left ventricle, while a total artificial heart is designed to replace the ventricles. The terminology can be confusing, so clinicians typically clarify which device is present and what chambers are supported.<\/p>\n\n\n\n<p><strong>Q: Why might an LVAD patient have a weak or absent pulse?<\/strong><br\/>\nMany durable LVADs provide continuous flow, which can reduce pulse pressure and make pulses harder to feel. Some patients still have a palpable pulse depending on how much the native left ventricle ejects and whether the aortic valve opens. Clinicians often use Doppler-based methods to assess blood pressure in this setting.<\/p>\n\n\n\n<p><strong>Q: Who is typically considered for a Left Ventricular Assist Device?<\/strong><br\/>\nLVAD therapy is typically considered for patients with advanced heart failure who remain significantly symptomatic despite optimized medical therapy, or for those with severe hemodynamic compromise. It may also be used as a bridge to transplant or as destination therapy depending on transplant eligibility. Candidate evaluation is comprehensive and varies by program.<\/p>\n\n\n\n<p><strong>Q: What tests are commonly done before LVAD implantation?<\/strong><br\/>\nCommon testing includes echocardiography, ECG, bloodwork (kidney\/liver function, blood counts, coagulation studies), and hemodynamic assessment often using right heart catheterization. Teams also assess comorbidities, infection risk, and psychosocial readiness. The exact workup varies by clinician and case.<\/p>\n\n\n\n<p><strong>Q: What are the most important complications to watch for after implantation?<\/strong><br\/>\nMajor categories include bleeding (including gastrointestinal bleeding), stroke or other thromboembolic events, infection (especially driveline-related), right ventricular failure, and device thrombosis\/malfunction. Presentations can be subtle, so structured monitoring is a core part of LVAD follow-up. The relative frequency of complications varies by device type and patient factors.<\/p>\n\n\n\n<p><strong>Q: Do LVAD patients need anticoagulation?<\/strong><br\/>\nMany do, because blood-contacting surfaces and altered flow patterns can increase thrombosis risk. However, the exact regimen (which medications, intensity, and monitoring approach) varies by device and center protocol. Clinicians balance clot prevention against bleeding risk.<\/p>\n\n\n\n<p><strong>Q: Can someone with a Left Ventricular Assist Device return to normal activities or work?<\/strong><br\/>\nMany patients regain meaningful functional capacity, but \u201cnormal\u201d varies with pre-implant condition, complications, and job demands. Activity planning also must account for equipment management (controller and batteries) and driveline care. Return-to-activity decisions are individualized and typically guided by the LVAD team.<\/p>\n\n\n\n<p><strong>Q: How do clinicians know if the LVAD is working properly?<\/strong><br\/>\nThey combine symptoms and exam findings with device parameters (such as speed, estimated flow, and power) and imaging, particularly echocardiography. Trends over time are often more informative than single readings. Alarms or sudden parameter changes prompt evaluation for preload\/afterload shifts, arrhythmias, cannula issues, thrombosis, or infection, depending on the scenario.<\/p>\n\n\n\n<p><strong>Q: What are typical next steps after someone is placed on an LVAD as a bridge to transplant?<\/strong><br\/>\nPatients usually continue transplant evaluation and listing processes while the device supports circulation. Follow-up focuses on rehabilitation, complication prevention, and maintaining transplant candidacy. Timelines and pathways vary by center resources and patient-specific factors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Left Ventricular Assist Device is a mechanical pump that helps the left ventricle move blood to the body.
