Po-02-208 characterization of atrial electrophysiological properties in patients with hypertrophic obstructive cardiomyopathy

Atrial fibrillation (AF) occurs frequently in patients with hypertrophic obstructive cardiomyopathy (HOCM) and the success rate of pulmonary vein isolation in these patients is less effective compared to other populations. This may be explained by the presence of an extensive arrhythmogenic substrate in both atria due to a primary atrial myopathy, but electrophysiological properties of the right (RA) and left atrium (LA) have never been investigated.
