400.08 Iatrogenic Right Bundle Branch Block After Alcohol Septal Ablation Does Not Negatively Impact Right Ventricular Function and Pulmonary Pressures

Hypertrophic obstructive cardiomyopathy (HOCM) treated with alcohol septal ablation (ASA) often results in right bundle branch block (RBBB). The effect of RBBB-induced dyssynchrony on cardiac function has not been well described. We sought to determine the effect of ASA-induced RBBB on RV function
