Values are mean ± SE. Left ventricular and RV function measured using electrocardiography before surgery and 4.5 months thereafter. Unoperated adult pigs were used as control subjects.
EDV = end-diastolic volume; EF = ejection fraction; ESV = end-systolic volume; FAC = fractional area change; FS = fractional shortening; IVSd = intraventricular septum in diastole; IVSs = interventricular septum in systole; LVIDd = left ventricular internal diameter in diastole; LVIDs = left ventricular internal diameter in systole; LVPWd = left ventricular posterior wall diastole; LVPWs = left ventricular posterior wall systole; RV = right ventricular; SV = stroke volume.
