Patent ductus arteriosus (PDA) represents the persistence of a communication between the aorta and pulmonary artery which is very essential for the fetus and normally shuts down in the majority within 24 hours of birth. This results in passage of pure blood from the aorta into the lungs and again depending on the size of the defect could be asymptomatic, present with recurrent lung infections and heart failure. Percutaneous closure is the treatment of choice unless it is accompanied by other birth defects which require surgery. Percutaneous closure is done with coils or devices. In small PDAs coil may suffice larger defects are preferably closed with devices. Through a catheter a device or a coil is positioned in the PDA resulting in closure of the duct. [More] [Less]

now one need not divide the chest bone entirely. Dr Mohammed Rehan Sayeed, chief cardiothoracic surgeon at Apollo Hospitals, Bangalore has developed the new technique of doing multiple vessel beating heart bypass surgery with partial division of the chest bone. He passionately calls it MINI BYPASS surgery. over 100 cases have been done with 2 year folow up and proudly a 99.5% success rate and 0% infection rate. [More] [Less]

Balloon pulmonary valvotomy Pulmonary valve is situated between the right ventricle and pulmonary artery. Pulmonary valvar stenosis is a birth defect where there is restriction to the complete opening of the pulmonary valve as a result of this the right ventricle has to pump harder for sufficient blood to reach the lungs for oxygenation. Generally well tolerated in most up to adulthood but rarely can present at birth with critical pulmonary stenosis requiring urgent treatment. The treatment involves opening the pulmonary valve. The treatment of choice is balloon pulmonary valvotomy where through the vein a ballon is advanced into the heart a placed across the pulmonary valve and inflated. This results in a tear along the commissure of the valve resulting in adequate opening of the valve. Balloon mitral valvotomy Mitral stenosis is almost always a result of Rheumatic fever in childhood is common in our country. The mitral valve separates the left atrium from the left ventricle. In mitral stenosis there is narrowing of the mitral valve orifice resulting in increase resistance to flow of blood from the left atrium to the left ventricle. One of the best treatment option is balloon mitral valvotomy where a balloon is placed across the mitral valve and inflated resulting in tear of the commissures. To reach the mitral valve from the venous side a puncture has to be made in the atrial septum. Complications associated with the procedure include need for emergency mitral valve replacement due to excess tear of the valve resulting in severe mitral valve leaking, and accidental puncture of the atrial free wall resulting in collection of blood in the pericardial space (pericardial tamponade). Balloon aortic valvotomy . The aortic valve is situated between the left ventricle and aorta. Narrowing of the valve orifice is known as aortic stenosis. The narrowing of the valve could be due to a birth defect or acquired. The common acquired causes are rheumatic or degenerative. In children balloon dilatation of the aortic valve is a good treatment option, but in adults surgery is the treatment of choice. Balloon dilatation in adults is done only in individuals who are high risk for surgery as a palliative measure. During balloon aortic valvotomy a balloon is placed across the stenotic aortic valve and dilated. To stabilize the balloon during inflation the heart is paced at a rate of 200 to 250 beats per minute. [More] [Less]

An atrial septal defect is a birth defect and consists of an opening in the wall that separates the left atrium from the right atrium. As a result of this pure blood comes into the right atrium from the left atrium and mixes with the impure blood. Thus the right atrium receives more blood than it is supposed to and pushes it into the right ventricle and from there in to the lungs. Due to this increased blood flow in the lungs these patients especially during childhood are prone for recurrent lung infections and they can have a progressive increase in the blood pressure in the lungs. Hence if this defect is causing a significant increase in the blood supply to the lungs (more than twice the blood supply to the body) it needs to be closed. ASDs may be classified into ostium primum, ostium secundum or sinus venosus. Traditionally surgery was needed to close all defects, but today a large percentage of ostium secundum can be closed without surgery. The device consists of two discs which are connected together by and waist which fits the size of the defect in the septum and this device is made of nitinol. A catheter ( a thin long tube) is passed along a large vein from the groin and advanced into the heart and guided from the right atrium into the left atrium through the atrial septal defect. The device is then stretched and taken through the catheter and the left atrial disc is released in the left atrium and the the catheter is pulled back into the right atrium and the right atrial disc is released in ti the right atrium. So now we have 2 discs, one in the left atrium and another in the right atrium. These two discs are connected by the waist which exactly fits the defect and closes it. This procedure is done under x-ray and ultrasound guidance. The patients are generally discharged on day two and need to take aspirin for a period of 6 months. [More] [Less]

I was visiting India for a vacation and suffered from chest pain. The doctors diagnosed it as coronary artery disease and advised me to have Bypass surgery. I was scared of it as already in oman they told me it was high risk for me to have bypass surgery i could die. I met Dr. Mohammed Rehan Sayeed and he gave me confidence told me it can be done through a minimal access approach called Mini Bypass surgery. I was lucky to meet him and thank god for sending me to him for surgery. iam a happy painfree man in 3 days after surgery ready to fly back to Oman. [More] [Less]

zoek is a baby with tetralogy of fallot with frequent cyanotic spells who came in for total corrective surgery. here is her mum reporting her experiance and their happiness with Dr. Mohammed Rehan Sayeed.

Beenish is an air ambulance coordinator and ER nurse who had an atrial septal defect. He was looking for minimal access approach and Dr.Mohammed Rehan Sayeed closed the defect with Endoscopic techniques. The main advantage of this being faster recuperation and lesser risk of infections apart from little to no pain. [More] [Less]
