Brief Answer:
It's a bridging surgery till he gets a donor for transplant.

Detailed Answer:
Hello dear,
Thank you for choosing HealthcareMagic for your query.
I am a cardiologist and would be answering your query.

Firstly sorry to hear about all the concerns for your son.
Secondly, don't panic, LVAD has excellent success rates and if implanted by skillful hands can play wonders.

The left ventricle of the heart is the chamber which is responsible for pumping blood through out the body. Due to multiple heart attacks and surgeries(CABG) most likely the ejection fraction of your son's heart(Amount of blood pumped out of heart every time it contracts) have dropped below 15% (Normal is 55-60%).

Reduced ejection fraction is responsible for reduced blood supply to coronaries. As there is less blood in coronaries heart will land up in bradycardia.

LVAD pulls blood from the left ventricle and pumps it into the aorta which further distributes it in the whole body.

As he has bradycardia also so without LVAD he has a risk of having a sudden cardiac arrest due to the failure of heart pump(as muscles have highly compromised blood supply).

An LVAD restores blood flow through his heart which has been weakened by disease. This helps to relieve symptoms which he is having.

Basically, it is a bridging surgery. Till he gets a donor for heart transplant this machine will help his body and would prevent cardiac arrest.

My advice would be to go for the surgery at the earliest.

Please attach/upload his 2D echo report, EKG, and other relevant documents, I need to go through them before giving any further opinion.

Hope the answer helped you and comforted you.
Waiting for reports.

Hello - Just wondering....I am a 41 yr old female, born with an aortic stenosis. I am a healthy person, never ever go to the doctor except back in Jan 2001 I had an aortic root enlargement and aortic valve replacement with a bovine valve. I have felt awesome afterwards. I have an extremely stressful job (office work not physical) just wondering if what feels like depression, tiredness, both arms ache with physical activity. My left thumb has had two occasions last week where it was stuck in a gripped position and could not move it for a minute or two. I know I am stressed as my neck has knots and am using alot of ben gay and advil. My blood pressure is actually perfect so I am assuming that it is NOT my heart. That is what I have come to the conclusion and just wanted to double check as I don t want to go to the doctor. Wouldn t that be a good indicator that I am just fine and it is just stress?

Hi, i am 32 years old I would like your advise on a heart surgery that i will undertake on Novermber 2010. In 1999 i had a correction to a coarctation with a 20mm Dacron interposition and in October 2000 i excised a bicuspid aortic valve, replaced with a 24mm cryopreserved aortic homograft. A couple of weeks ago i was admitted to hospital with left heart failure, pulmonary oedema and orthopnea. My surgent said that the valve replaced ten years ago is leaking and must be replaced however, he gave me two options which consist of the two types of valves i can choose one from. I am need of an aortic valve and root. The first option was to have a metal valve which they say lasts longer. The second option was replacing the present leaking valve with one that is the same. So i would be grateful if you can advise me which of the two you would recommend for me. I would also appreciate it if you could tell me the chances of the operation succeeding and how far technology will get in case of a further operation within the next ten years. If you would like any further information just contact me via email. I would be grateful if you can respond back to me as soon as possible. Thank you
