Figure 1 Histograms of magnetic resonance imaging variables in patients with right ventricular (RV) outflow tract patch repair (n = 75) and RV-to-pulmonary artery conduit (n = 25). (A) % pulmonary regurgitation; (B) indexed RV end-diastolic volume (EDV); (C) indexed RV end-systolic volume (ESV); (D) RV ejection fraction.
