Right ventricular systolic time intervals (RVSTI) and noninvasive Dopplerderived pulmonary blood flow were measured before and after surgical ductus ligation in 18 otherwise healthy infants and children who were older than 3 months of age. Right ventricular preejection period (PEP) and the ratio of preejection period and right ventricular ejection time (PEP/REVET), both corrected or uncorrected for heart rate, decreased significantly following surgery (PEP 71±14 vs. 50±13, p
