Risk marker profiles in patients treated with percutaneous septal ablation for symptomatic hypertrophic obstructive cardiomyopathy

Different studies have shown a good long-term survival with improvement of symptoms and hemodynamics after percutaneous septal ablation (PTSMA), similar to myectomy considered to be the therapeutic “gold standard” for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). Furthermore, desobliteration of left ventricular (LV) outflow may modify features of the disease considered to be risk-relevant, such as magnitude of LV hypertrophy,...
