Subacute left ventricular outflow tract obstruction after transapical closure of a mitral paravalvular leak in the region of the aortomitral curtain.
نویسندگان
چکیده
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.

Mitral valve replacement complicated by iatrogenic left ventricular outflow obstruction and paravalvular leak: case report and review of literature
BACKGROUND Left ventricular outflow tract (LVOT) obstruction and paravalvular leak (PVL) are relatively uncommon, but are serious complications of prosthetic valve replacement. CASE PRESENTATION We present a case that displays the unique therapeutic challenges of treating a patient who developed both LVOT obstruction and mitral PVL after undergoing surgical aortic and mitral valve replacement...
متن کاملBail-Out Alcohol Septal Ablation for Left Ventricular Outflow Tract Obstruction After Transcatheter Mitral Valve Replacement.
A 76-year-old woman with degenerative mitral valve disease was referred for refractory heart failure. An echocardiogram showed the presence of a massive mitral annular calcification with severe stenosis (mitral valve area, 1.0 cm; mean gradient, 11 mm Hg) and a small left ventricular cavity with a 23-mm septal bulge without obstruction (Figures 1A to 1C, Online Video 1). Computed tomography (CT...

متن کاملPercutaneous retrograde transfemoral closure of mitral paravalvular leak in 3 patients without construction of an arteriovenous wire loop.
Percutaneous closure of paravalvular leaks has emerged as an alternative to repeated surgeries. Different percutaneous techniques and various devices have been used, off-label, for paravalvular leak closure. For mitral leaks, antegrade transseptal, retrograde transfemoral, and retrograde transapical techniques have been developed. In the antegrade transseptal approach, an arteriovenous guidewir...
متن کاملTranscatheter closure of paravalvular defects using a purpose-specific occluder.
OBJECTIVES This study sought to describe a method of paravalvular leak closure using a purpose-specific occlusion device. BACKGROUND Transcatheter closure of paravalvular leaks has been hampered by technical challenges, the limitations of available imaging modalities, and the lack of closure devices specifically designed for this purpose. METHODS Patients with severe symptomatic paravalvula...
