Figure 3. Diagram showing freedom from the composite end point (cardiac death and sustained and nonsustained ventricular tachycardia) during follow‐up from the cardiovascular magnetic resonance (CMR) study using Kaplan‐Meier curves according to the peak right ventricular outflow tract (RVOT) gradient of ≥25 and <25 mm Hg.

Using Cox proportional hazard analysis, a peak RVOT gradient ≥25 mm Hg was associated with a >3‐fold increased risk for adverse cardiovascular events (hazard ratio [HR], 3.69; 95% CI, 1.47–9.27; P=0.005).
