Valvular Heart Surgeon. Valvular Heart Disease is still very common in our country. Most of these are due to Rheumatic Heart Disease. Normally these start with recurrent throat infection and joint pains in childhood / teen age. These young adults develop valve problems. There four valves in the human heart out of which single or two valves may be affected. The commonly affected valves are known as mitral and aortic. Sometimes tricuspid valve is also involved. Valve problems may be either narrowing (stenosis) or leaking (regurgitation) or a combination of both. Valves once damaged require either a repair or a replacement. If it is not tackled in time it may cause heart to become enlarged and increased pressures in the lungs. This leads to permanent changes in the lungs.
