Diverticulum of mitral valve.

Diverticulum arising from the heart is an uncommon finding. They are incidentally detected by echocardiography as masses arising from the cardiac valves. We present a case of an incidental finding of a diverticulum arising from the mitral valve. This was initially detected by Transthoracic echocardiography and later confirmed by transesophageal echocardiography and pathologic appearance.
