Initial results of combined anterior mitral leaflet extension and myectomy in patients with obstructive hypertrophic cardiomyopathy.
OBJECTIVES The purpose of this study was to describe the clinical and functional results of combined anterior mitral leaflet extension and myectomy in patients with hypertrophic obstructive cardiomyopathy. BACKGROUND Septal myectomy is the most commonly performed surgical procedure in patients with hypertrophic cardiomyopathy and left ventricular outflow tract obstruction. Because of the role...
متن کاملSustained improvement after combined anterior mitral valve leaflet retention plasty and septal myectomy in preventing systolic anterior motion in hypertrophic obstructive cardiomyopathy in children.
OBJECTIVE Anatomic alterations of the mitral valve such as increased mitral leaflet area, length and laxity, and anterior displacement of the papillary muscles in hypertrophic obstructive cardiomyopathy predispose patients to residual systolic anterior motion and persistence of outflow obstruction and mitral regurgitation after septal myectomy. We investigate the long-term results of combined a...
متن کاملMinimally Invasive Trans-Mitral Septal Myectomy to Treat Hypertrophic Obstructive Cardiomyopathy
A 43-year-old man with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) was admitted to our hospital with aggravated exertional dyspnea and successfully treated with robotic transmitral septal myectomy. Minimally invasive transmitral septal myectomy may be a feasible surgical option for the treatment of HOCM in selected cases as an alternative to transaortic myectomy.
متن کاملPercutaneous versus surgical treatment for patients with hypertrophic obstructive cardiomyopathy and enlarged anterior mitral valve leaflets.
BACKGROUND The purpose of this study was to compare percutaneous transluminal septal myocardial ablation (PTSMA) and septal myectomy combined with mitral leaflet extension (MLE) in symptomatic hypertrophic obstructive cardiomyopathy patients with an enlarged anterior mitral valve leaflet (AMVL). Both PTSMA and myectomy reduce septal thickness and left ventricular outflow tract (LVOT) gradient; ...
متن کاملSeptal myectomy and myotomy attenuate left ventricular hyper-contractility in a child with hypertrophic obstructive cardiomyopathy.
Septal hyper-contractility is thought to be the principal cause of significant left ventricular outflow tract obstruction (LVOT) and systolic anterior motion (SAM) of the mitral valve by making the distance between the mitral valve and papillary muscle shorter. A seven-year-old patient with severe hypertrophic obstructive cardiomyopathy underwent direct interventricular septal myectomy/myotomy ...
