Most transplants are well tolerated with long-term survival, but require very strict medication reliability. Rejection of a new heart is rarely fatal and can be treated by medicines. Matching a new heart well up front is critical.
They then manage the patient until out of the hospital, at which time the cardiologist takes back over long-term management.
the mitral valve and whether some of the surrounding tissues can be fixed to allow the valve to function more normally. A non-invasive echocardiogram is necessary to evaluate the valves prior to the decision and can be discussed with you before surgery. I usually show the images to the patient's in my office. Repair is done by removing redundant tissue or tightening the surrounding structures. In some cases this is not possible, thus the valve would be replaced. Repair, leaving the patient's native valve in place is preferable with better long-term outcomes.
