Lastly, we'll describe the benefits of minimally invasive techniques which are being used more commonly by surgeons as the technology at their disposal continues to develop. Valvular problems that can occur your heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. Each of them can malfunction by failing to open or close properly. When a valve fails to open all the way, the passageway through which blood flows becomes restricted. This condition is called stenosis and can occur if the valve has stiffened due to calcium deposits and scars. When a valve fails to close completely, blood can flow back into the chamber it has exited. This condition is called regurgitation and can happen when the individual leaflets lack the fibrous support they need. When the valves malfunction, heart valve surgery is necessary in order to correct the problem. meaning bathtubs viagra commercials Possible surgical solutions any valve that is failing to do its job can either be surgically repaired or replaced. viagra discount A surgeon will make the decision only after he has inspected the valve.
