There are four valves in the heart that mainly control the flow of blood. Two of the valves are on the right side and the other two are on the left side of the heart. The left valves most affected in heart problems in adults are the aortic valve and the mitral valve. These heart problems include significant stenosis (narrowing) and leakage, which can affect the heart in a variety of ways, including chest pain, fainting, shortness of breath, and irregular heartbeats or arrhythmias. Echocardiography and cardiac catheterization are common diagnostic techniques used by cardiologists for assessment. The Heart Specialist In Panipat then refers the patient to a cardiac surgeon to correct the valve problem. Surgeons may use mechanical or tissue flaps during surgical procedures.
