Balloon mitral valvotomy. A new technique.

Balloon mitral valvotomy is a new technique for non-operative treatment of mitral stenosis and is performed by using single or double balloon. The technique is complex, involves transseptal puncture, however, can be safely performed in experienced catheterisation laboratory. The technique has been applied in calcific and noncalcific valves, mitral restenosis and also in presence of atrial fibrillation. The results with double balloon valvotomy at the present time is costlier than closed mitral valvotomy. The technique is promising and large trials are awaited to see its future status.
