Figure 1 Indexed ventricular volumes. A, Indexed RV end-diastolic and end-systolic volumes for patients with repaired ToF and patients with PS treated with valvotomy. B, Indexed LV end-diastolic and end-systolic volumes for patients with ToF and PS. Results are expressed as mean ± standard deviation. RV, Right ventricular; ToF, tetralogy of Fallot; PS, pulmonary stenosis; EDV, end-diastolic volume; ESV, end-systolic volume.

Figure 2 RVOT contractility was qualitatively compared between patients with repaired ToF and patients with PS treated with valvotomy. Patients in whom the RVOT was akinetic or contracted paradoxically (expansile in ventricular systole) were deemed abnormally contractile (clear panels). Patients with normally contractile RVOT are shown in the shaded panels. RV, Right ventricular; LV, left ventricular; ToF, tetralogy of Fallot; PS, pulmonary stenosis.

Figure 3 RV volumes and ejection fraction in patients with contractile RVOT. A, RV end-systolic volumes for patients with repaired ToF and patients with PS treated with valvotomy with contractile RVOT.
