  Objective: This study aimed to examine exercise hemodynamic parameters and exercise capacity in adults with repaired tetralogy of Fallot (rTOF) obtained during supine bicycle echocardiography. Background: In addition to volumetric MRI parameters, exercise capacity in adults with rTOF is often used to determine timing for pulmonic valve replacement (PVR). Supine bicycle echocardiography is useful in measuring right ventricular (RV) hemodynamic parameters and quantifying exercise capacity and myocardial workload. Methods: Supine bicycle echocardiograms performed since 2002 were retrospectively reviewed among 33 adults with rTOF followed at a single adult congenital heart disease center. Echocardiographic and hemodynamic parameters were measured before and at peak exercise. Results: Mean age was 36 ± 12 yrs and severe pulmonic regurgitation (PR) was present in 56%. Mean exercise d..
