Design
Cohort
Key result
An initially prolonged right ventricular systolic time interval (ratio > 0.50) strongly predicted the development of severe transient tachypnea in term neonates (RR 17.5, p<0.001).

May warrant early echocardiography for risk stratification in transient tachypnea; leaves open whether RVSTI-guided care improves outcomes.

Relative Risk: 17.5
p-value: p=<0.001
Initial measurement of right ventricular systolic time intervals by echocardiography before 4 hours of age strongly predicts the development of severe transient tachypnea in term neonates.
Kati Heinonen (1983) conducted a cohort in Transient tachypnea (TTN) (n=42). Right ventricular systolic time interval (RVSTI) ratio > 0.50 vs. RVSTI ratio ≤ 0.50 was evaluated on Development of severe TTN (RR 17.5, p=<0.001). An initially prolonged right ventricular systolic time interval (ratio > 0.50) strongly predicted the development of severe transient tachypnea in term neonates (RR 17.5, p<0.001).
