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 due to anomalous mitral valve: successful mitral valve replacement in a four month old infant.
A four month old infant was investigated for heart failure was found to have mitral incompetence and severe subvalvar aortic stenosis. The left ventricular outflow tract obstruction was found to be due to an anatomically anomalous mitral valve. The obstruction could only be relieved by removal of the mitral valve and its replacement with a St Jude's prosthesis. Two years after operation the chi...
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...
