Forgive me, but what's wrong with this scenario, you got advice from 2 medical professionals with whom you entrust your life and when there's a difference of opinion, you come to a slew of strangers who frankly are a bit shady...
Okay so you've gotten advice from your Cardiologist, your Cardio-thoracic surgeon, and a lawyer. Let's think this through. We all know Donnie has been guided since at least Nov 3rd by a herd of lawyers, the results of which are shall we say suspect, so let's drop the lawyer from the candidates.
Then there's your Cardiologist, now he/she is highly educated and knows a lot about the mechanical aspects of the heart as well as what can and often happens with various conditions, so he/she should be held in high esteem regarding this decision.
Finally there's the Surgeon. Now he/she has seen your broken down heart first hand and can readily say both it's current condition as well as the probability of future break downs.
My opinion, which as they say is worth what you paid...go with the worst case scenario that a specialist will monitor and watch for. If it never comes to pass, great. If it does, they'll catch it and correct the problem before you need the lawyer.
Good luck
