SURGICAL-CORRECTION OF HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY WITH COMBINED MYECTOMY, MOBILIZATION AND PARTIAL EXCISION OF THE PAPILLARY-MUSCLES

A modified surgical technique for correction of hypertrophic obstructi ve cardiomyopathy (HOCM) with extended myectomy together with mobilisa tion and partial excision of papillary muscles was performed between 1 /79 and 12/92 in 58 severely symptomatic patients refractory to medica l treatment. Low hospital mortality rate (1.7%) and perioperative comp lication rate, an equally low linear mortality 1.4% per patient year a nd excellent functional status (77% class I or II NYHA) of the patient s at follow-up demonstrate the necessity of a comprehensive approach f or correction of severely symptomatic patients with HOCM and the feasi bility of our operative strategy.
