Ameliorating the severity of sleep-disordered breathing concomitant with heart failure status after percutaneous transluminal septal myocardial ablation for drug-refractory hypertrophic obstructive cardiomyopathy

The coexistence of sleep-disordered breathing (SDB) and hypertrophic obstructive cardiomyopathy (HOCM) has widely been recognized; however, the impact of percutaneous transluminal septal myocardial ablation (PTSMA) for HOCM on SDB remains unknown. Herein, we examine cardiorespiratory polygraph parameters in patients with drug-refractory HOCM before and after PTSMA. Forty consecutive drug-refractory HOCM patients, admitted to Keio University...
