Case report: septal radiofrequency ablation for sigmoid ventricular septum-related dynamic obstruction: with observations suggesting left bundle branch block as a potential therapeutic collaborator

Abstract Background Sigmoid ventricular septum (SVS) can cause dynamic left ventricular outflow tract obstruction (LVOTO) during stress. Radiofrequency ablation (RFA) has been used for septal reduction in hypertrophic obstructive cardiomyopathy, but its application in SVS is limi...
