Reverse Septal Curvature: A Novel Comprehensive Risk Marker of Nonsustained Ventricular Tachycardia in Hypertrophic Cardiomyopathy

The field of sudden cardiac death risk stratification in hypertrophic cardiomyopathy continues to search for new markers. Despite decades of clinical investigation, few new clinical or imaging characteristics have been introduced into current Hypertrophic Cardiomyopathy (HCM) guidelines (1). Current risk factors that predict sudden cardiac death (SCD) include: massive segmental left ventricular thickening ≥ 30 mm; SCD in a first-degree relative or other close relative 50 years or younger, deemed to be due to HCM; unexplained syncope (deemed clinically not be neurocardiogenic, or due to left ventricular outflow tract (LVOT) obstruction); recurrent ventricular tachycardia on ambulatory ECG monitoring ; late gadolinium enhancement (LGE) ≥15% of LV mass on cardiac magnetic resonance imaging (CMRI); degeneration into LV systolic dysfunction; and apical aneurysm (1,2).
