Unusual Cause of Left Ventricular Pseudoaneurysm

Closed mitral valvotomy (CMV) became an accepted surgical procedure to open a stenotic mitral valve (MV) about 50 years ago. CMV is performed through an incision in the left atrial appendage. Tubbs dilator is passed in to the left ventricle via the apex and then advanced retrogradely through the stenosed MV and is then opened within the orifice to split the commissures. The dilator is then removed and the orifice closed. Incisional left ventricular pseudo aneurysm has been described as a rare complication of this technique. Here we encountered a similar scenario. Percutaneous transmitral commissurotomy has virtually replaced CMV. But with the expanding use of the transapical approach to treat a variety of structural heart diseases, especially transcutaneous aortic valve replacement, one is likely to encounter similar complications in the modern era also.
