Balloon Valvuloplasty for Aortic Valve Stenosis

Balloon valvuloplasty (also called valvulotomy or valvotomy) is a procedure that widens a heart valve that is narrowed. The cause of this narrowing in the aortic valve is aortic valve stenosis. During this procedure, the doctor puts a thin, flexible tube called a catheter into a blood vessel in your upper leg (groin)…

Aortic Valve Stenosis

Aortic valve stenosis is a narrowing of the aortic valve between the lower left chamber of the heart and the aorta, which supplies blood to the body. A narrowed aortic valve forces the lower left chamber of the heart to pump harder to get enough blood through the valve. Aortic valve stenosis can be caused by a…

Mitral valve regurgitation

Mitral valve regurgitation happens when the mitral valve does not close tightly enough after blood flows through the valve into the lower chamber of the heart. This makes a small opening in the valve even when the valve is closed. This opening can let blood leak (regurgitate) back into the upper chamber of the heart.

Mitral Valve Regurgitation

Mitral valve regurgitation (MR) is the leaking or backflow of blood through the valve between the upper left heart chamber (atrium) and the lower left heart chamber (ventricle). If serious, this condition can lead to a backup of blood in the left atrium and the lungs, cause enlargement of and damage to the left…
