Surgical correction of hypertrophic obstructive cardiomyopathy withcombined myectomy, mobilisation and partial excision of the papillarymuscles

Abstract

A modified surgical technique for correction of hypertrophic obstructivecardiomyopathy (HOCM) with extended myectomy together with mobilisation andpartial excision of papillary muscles was performed between 1/79 and 12/92in 58 severely symptomatic patients refractory to medical treatment. Lowhospital mortality rate (1.7%) and perioperative complication rate, anequally low linear mortality 1.4% per patient year and excellent functionalstatus (77% class I or II NYHA) of the patients at follow-up demonstratethe necessity of a comprehensive approach for correction of severelysymptomatic patients with HOCM and the feasibility of our operativestrategy.
