Résumé
To assess right ventricular systolic time intervals, specifically, time to peak velocity (TPV) in the pulmonary artery as a marker of persistent pulmonary hypertension of the newborn (PPHTN). This was a retrospective case-control study of 30 infants with pulmonary hypertension requiring intensive care management. Cardiac ultrasounds were re-analysed, comparing TPV measurements to a group of 31 controls who had cardiac ultrasounds performed for incidental murmurs with structurally normal hearts. Time to peak velocity was significantly shorter in the PPHTN group compared to controls, 47 vs. 95 ms, respectively. This was statistically significant with a P-value of <0.001. Time to peak velocity in the pulmonary artery is a useful marker of PPHTN in the first week of life. This measurement is especially useful if neither tricuspid regurgitation or a patent ductus are present for interrogation on ultrasound.
