Cardiopulmonary Exercise Test Parameters at Three Months After Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy Are Associated With Late Clinical Outcome

Background Alcohol septal ablation (ASA) is an established interventional treatment for hypertrophic obstructive cardiomyopathy (HOCM) patients with drug refractory symptoms. This study investigated the prognostic value of cardiopulmonary exercise test (CPET) in relation to the late clinical outcome. Methods Twenty-one (21) HOCM patients underwent CPET before and 3 months after ASA and were followed yearly thereafter. Clinical success was...
