 Hello, I am Dr. Devananda, Head of the Department of Cardiac Surgery at Manipal Hospitals. I have been practicing cardiac surgery for the last 18 years. Now, leaking metal valve based on the intensity of leak and symptoms. Third, the size of the ventricle or so-called the pumping chamber decides when to intervene. If patient is symptomatic, yes, repair is indicated. If the ventricular size is enlarging consistently and reaches certain dimensions, yes, intervention is indicated. Third is, suppose these kind of valves in the leakage may be mild or moderate, but if it gets infected and the leakage worsens, yes, intervention is indicated.
