Hi, may I answer your health queries right now ?  Please type your query here...My husband underwent mitral valve repair last year which failed. He needs another surgery to repalce the mitral valve. How dangerous is surgery and are there different types of tissue valves and their expected life span.?
Howell come to ChatDoctorI really appreciate your concern, such case really needs complete clinical information but once the surgery done, and it was the post surgical complications are there then second attempt of repairs depends upon what type of complication it was, what type of valve is compatible to the patient that depends upon the cardiac parameters, very little information you gave here, hope this information helps.
