Specialized echo tests may include exercise or the use of special drugs and may be needed to define the severity of obstruction and to assess the mitral valve; Good results have been reported for patients who had transaortic subvalvular myomectomy [1. Twelve patients (3%) had myectomy performed after alcohol septal ablation due to recurrent heart failure symptoms (NYHA class III) caused by persistent outflow tract obstruction. After NSRT, the incidence of pacemaker implantation for complete heart block was higher (22% vs. 2% in surgery; p = 0.02). Although both septal myectomy after failed septal ablation and septal ablation after failed septal myectomy have been carried out successfully, the former is more common. Postoperatively, 27 of 29 patients reported symptomatic improvement and had greatly reduced left ventricular outflow gradient. I just joined the group and am looking forward to connecting with everyone. Cardiopulmonary responses to exercise in patients with hypertrophic cardiomyopathy. After myectomy, survival free from all-cause mortality is 98%, 96%, and 83% at 1, 5, and 10 years, and survival free from HCM-related mortality (heart failure and sudden death) is 99%, 98%, and 95%, respectively.
