Right Ventricular Function in Congenital Heart Defects Assessed by Regional Wall Motion

To develop a simple method to assess right ventricular function by angiography.Conventional methods of evaluating right ventricular function are inaccurate, cumbersome, and expensive.We analyzed biplane right ventricular angiograms taken in the posterior-anterior and lateral projections using software to measure right ventricular volumes and regional wall motion in 78 patients with normal hearts (n = 29), atrial septal defects (ASD n = 13),...
