isolated cleft of the posterior leaflet(passive) caused bysevere mitral regurgitation

Immediately after predilation of the aortic valve ( 18-mm balloon ) , the patient developed severe hypotension and dynamic left ventricular outflow tract ( LVOT ) obstruction with systolic anterior motion of the anterior mitral leafletcausingsevere mitral regurgitation

only when there is a significant independent abnormality of the mitral valvecausingsevere mitral regurgitation
