It sounds like your friend is going in for a bypass operation. In this procedure "extra" veins are taken from the leg (saphenous veins) and used to replace blocked arteries of the heart. An incision is made in the centre of the chest to access the heart. The blocked (atherocslerotic) arteries prevent the flow of blood reaching the heart muscle. When you do exercise, or any other activity that increases your heart rate (e.g. stress), the oxygen requirements of the heart muscle increase. In someone with blocked coronary arteries, blood flow and therefore oxygen delivery cannot meet the demands of exertion. As a result the patient experiences episodes of angina (chest pain) when exerted, and if the blockage is severe, at rest. This condition is referred to as coronary artery disease. Please note veins may be harvested from other parts of the body depending on a number of factors, however the leg is most common. The terms double and triple bypass are in reference to the number of blocked arteries that are being operated on. For example in a double bypass, two sections of artery are replaced by vein; and in a triple bypass, three sections are replaced. Bypass surgery is indicated in those with severe coronary artery disease as assessed by scans performed by Doctors and in those who do not respond/cannot have other treatment for various reasons that I will not go into here. Bypass operations are common these days and as such the rates of complications are low. Any surgical procedure has risks. These general risks include infection, deep vein thrombosis due to immobility/surgery itself, keloid scarring, anaesthetic complications and death. Precautions are taken for all of these including theatre hygiene etc. There are bypass complications such as pulmonary emboli (blood clots lodging in the lungs), stroke, and heart attack. These complications are fairly rare. Bypass surgery is the best option even in light of these rare complications and is indicated when the risk of no-treatment is greater than treatment as assessed by a Doctor. Following the surgery your friend should make an effort to change his/her lifestyle. This includes stopping smoking, drinking and avoiding fatty foods. A healthy diet and exercise should be commenced to prevent further damage to the heart arteries. Is this is not implemented he/she may run the risk of further blockage and a return of the symptoms mentioned. I hope this is clear and helps you. If you have further questions ask a Doctor in hospital when you visit your friend.

My dad is 75 years old and in good health. He was told that he needs an aortic valve replacement. He was informed that because he is in good health open heart surgery would be the procedure done on him. Can the biological replacement be done minimally invasive or does it have to be done by open heart surgery?

I am 28yrs old, VSD was detected in my heart during my childhood, however doctors suggested to wait and see if it closes by itself, however when 27 the symptoms grew and the Hole in Heart lead to dilation and slight rupture of Sinus of valsalva, I ended up having an open heart invasive surgery. Surgery treatment included closure of VSD as well as RSOV

I was told there was imbalance pressure at my left and right half of heart, and pressure difference was roughly 20 or 30 mmHg more than should have been for a normal heart, meaning one side(right) of heart was handling more pressure by 20mmHg than should have while the other half(left) was handling pressure by 20mmHg lesser than should have, and also there was mixing of oxygenated and de-oxygenated blood.

I have not gained weight even after surgery(surgical treatment done when i was 27yrs old)

My questions are:
1. What is my life expectancy? Have my life expectancy decreased by now than compared to what it would have been if I would have been normal from my birth, is there a maximum cap on the number of years I can live now?

I did try asking above question to my cardio surgeon but he did not provide a clear answer, just mentioned that I am normal now and would not have any problems

2. Before surgery I was told that the reason I had long hands and underweight was due to the defect VSD, due to the pumping of the heart at wrong pressures and causing different pressure values at arteries and veins, So my question is would I really some back to normal after the surgery? would my heart not have been adjusted to the earlier pressures(i would imagine the structure of heart to be adopted since the defect was from birth), so rectifying RSOV alone would have been sufficient and that closure of VSD wouldnt have adverse effect on my body as well as heart?

3. Since lesser percentage of oxygenated blood was circulating through my system including my brain all these years, would I have any issues like memory loss or underdeveloped brain, attributed due to that?

4. Would I be prone to any of the heart diseases in future or and related diseases like high/low Blood Pressure?

Please respond to my queries asap.
