I am a 53 year old male and have been diagnosed with the following: mitral valve prolapse syndrome, mitral, aortic, tricuspid and pulmonary insuff. and regurg. According to my Cardiologist, if surgery is performed, the only valve that would be repaired or replaced would be my mitral valve, but I have been told that my aortic valve is also quite severely insufficient and also had mild to moderate regurg, why would the surgeon only replace just one valve?
