Percutaneous transvenous balloon valvotomy in a patient with severe calcific mitral stenosis

Percutaneous transvenous balloon mitral valvotomy was performed successfully in a 57 year old man with refractory congestive heart failure due to calcific mitral stenosis. Cardiac surgery was not an option because of other major medical problems. Balloon mitral valvotomy was performed using the transseptal technique. The interatrial septum was dilated with the use of an 8 mm balloon catheter to allow passage of larger balloon valvotomy catheters to the mitral anulus. The procedure resulted in a marked decrease in the diastolic transmitral gradient from 20 to 4 mm Hg. This decrease was associated with an increase in cardiac output from 3.4 to 5.7 liters/min. Mitral valve area increased from 0.7 to 2.5 cm2. Balloon valvotomy did not result in significant mitral regurgitation. This case indicates that further trials are warranted to evaluate percutaneous transseptal mitral valvotomy for the treatment of patients with mitral stenosis.
