Abstract
OBJECTIVE: To compare the left ventricular eccentricity index (EI) and tricuspid valve systolic-diastolic (SD) ratio in infants at risk of bronchopulmonary dysplasia (BPD) and pulmonary hypertension (PH). STUDY DESIGN: Review of echocardiograms performed on infants born at ≤ 28 weeks' postmenstrual age, categorized into the following three cohorts: BPD and PH (n = 13); BPD only (n = 16); and controls (n = 59). EI was measured from a parasternal short axis 2D image. The SD ratio was measured from the continuous wave Doppler tracing. Groups were compared using Kruskal-Wallis and Wilcoxon rank sum tests. RESULT: EI and SD ratios were successfully measured in all infants. There were no differences between controls and BPD cohort. In contrast, the BPD and PH cohort had increased systolic EI (1.46 vs. 1.00-1.01), diastolic EI (1.47 vs. 1.00), and SD ratio (1.12 vs. 0.97-1.00) compared with controls and BPD only cohort (p ≤ 0.01 for all). CONCLUSION: The EI and SD ratio may be useful as a screening tool for PH in this population. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.
