title: Subacute left ventricular outflow tract obstruction after transapical closure of a mitral paravalvular leak in the region of the aortomitral curtain.
abstract: We report a rare case of progressive left ventricular outflow tract (LVOT) obstruction after percutaneous device closure of a mechanical prosthetic mitral valve (MV) paravalvular leak (PVL) in the region of aortomitral curtain in a patient who also had small mechanical aortic valve prosthesis with patient-prosthesis mismatch.
