- Abstract: BACKGROUND: To detect progression of right ventricular (RV) systolic dysfunction (RVSD) in asymptomatic preterm children from infancy to 24-month corrected age, using velocity vector imaging (VVI). METHODS: Retrospective study comparing sequential RV longitudinal peak systolic strain (LPSS) from 24 children born at < 33 weeks of gestational age and 10 term infants recruited as controls, obtained at a mean of 4-month (first exam) and 24-month corrected age (second exam). RESULTS: In 7/24 (29.2%) of preterm children, RV LPSS of < 16%, defined as RVSD, was detected at the second exam; 5/7 of these children had RV LPSS > 16% at the first exam, and only 2/7 of these children had a history of moderate or severe bronchopulmonary dysplasia. CONCLUSION: In asymptomatic preterm children, routine echocardiographic screening using VVI could detect RVSD which could progress from 4–24 month corrected age.
