Late left ventricular outflow tract obstruction following mitral valve replacement.
A 66-year old male presented with presyncope 14 years following mechanical mitral valve replacement. Echocardiography demonstrated the remainder of an elongated anterior mitral valve leaflet (AMVL) with systolic anterior motion obstructing the left ventricular outflow tract (Fig. 1 and Supplementary Video 1). Owing to previous intracranial bleeding, the completion of AMVL resection was performe...
متن کاملLeft ventricular outflow tract obstruction after mitral valve replacement.
We describe a patient with left ventricular outflow tract obstruction after mitral valve replacement preserving the anterior subvalvular apparatus. Postoperative transesophageal echocardiography demonstrated systolic narrowing of the left ventricular outflow tract by a bulging septum and systolic anterior motion of the preserved anterior mitral leaflet. Septal myectomy and transaortic mitral ap...
متن کاملLeft Ventricular Outflow Tract Obstruction
Patients with hypertrophic cardiomyopathy (i.e., asymmetric septal hypertrophy) may show obstruction to left ventricular outflow under basal conditions or with provocative maneuvers. The presence of dynamic left ventricular outflow tract obstruction in patients with concentric ventricular wall thickening (but without abnormalities of the aortic valve) has been less well appreciated. Clinical an...
متن کاملLeft Ventricular Outflow Tract Pseudoaneurysm after Aortic Valve Replacement.
Left ventricular outflow tract pseudoaneurysm is an uncommon complication following aortic valve replacement (AVR), occurring most frequently secondary to endocarditis. We present a case of a 47-year-old female with a history of intravenous drug abuse and a past surgical history of two AVRs (2001 and 2009 with aortic root replacement for endocarditis) who presented with symptoms of lower extrem...
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...
