Regional differences in right ventricular systolic function as determined by cine magnetic resonance imaging after infundibulotomy.
The right ventricle of subjects after infundibulotomy (n = 20) and of subjects free of right ventricular disease (n = 19) was partitioned into the infundibular and sinus segments to examine the relative size and function of each. Excellent agreement was found between observers for measuring regional volume and ejection fraction. Although the surgical subjects had lower infundibular ejection fraction and higher indexed volumes, most had preserved sinus ejection fraction.
