Can anyone tell me how serious mitral valve prolapse is ? with mild regurgitation? I had an echo done due to heart palpitations and I found out I have mitral valve prolapse with mild regurgitation . I am 36 years old. Is this serious? What precautions should I follow? Will I need a new valve? Please help I am so scared. I have tried numerous times to ask my doctor but he blows me off and says not to worry. He is the only board certified md in my rural area.
