The P-values shown are derived from two-tailed unpaired Student’s t-test for continuous variables. Patients who were non-RV pacing-dependent at 30 days and patients who were RV pacing-dependent at 30 days patients were separately compared. Continuous variables are reported as the mean plus or minus the standard deviation. HU: Hounsfield Units; LVOT: left ventricular outflow tract; RCC: right coronary cusp; NCC: non-coronary cusp; LCC: left coronary cusp; RV: right ventricular.
