Basal antero-septal anomalous papillary muscle in hypertrophic obstructive cardiomyopathy

Basal antero-septal anomalous papillary muscle in hypertrophic obstructive cardiomyopathy

Septal myectomy, papillary muscle resection, and mitral valve replacement for hypertrophic obstructive cardiomyopathy: a case report.

We report a case of hypertrophic obstructive cardiomyopathy (HOCM) successfully treated with septal myectomy and mitral valve replacement (MVR) combined with a resection of the hypertrophic papillary muscles. The patient, a 74-year-old woman, first underwent the conventional septal myectomy through aortotomy. The papillary muscles revealed a marked hypertrophy, but extended myectomy and precise...

Anomalous Papillary Muscle Insertion Causing Dynamic Left Ventricular Outflow Tract Obstruction without Hypertrophic Obstructive Cardiomyopathy

Anomalous papillary muscle insertion directly into the surface of the mitral valve leaflet is rare, especially in a subject without apparent evidence of hypertrophic cardiomyopathy. We present a case of this isolated congenital malformation producing two hemodynamic sequelae of dynamic left ventricular outflow tract obstruction and severe mitral regurgitation.

[Septal ablation in hypertrophic obstructive cardiomyopathy].

Rev Esp Cardiol 2003;56(12):1231 1231 A 62-year-old patient had symptomatic hypertrophic obstructive cardiomyopathy diagnosed six years ago. Despite medical treatment, dyspnea progressed during follow-up and a two-chamber pacemaker had been implanted one year previously. The reason for the current hospitalization was worsening symptoms (functional class III). The dynamic left ventricular outflo...

Septal myectomy for obstructive hypertrophic cardiomyopathy.

Septal myectomy effectively relieves left ventricular outflow tract obstruction (LVOTO) and cardiac symptoms in both adults and children with obstructive hypertrophic cardiomyopathy (HCM). Abnormal attachments of the papillary muscles and chordae and other cardiac lesions can be repaired at the same time. Early mortality for isolated septal myectomy in both children and adults is low (0% to 2.5...
