“… 7) Therefore, measuring decreases in RV strain in the longitudinal direction in the presence of afterloads, such as increased pulmonary vascular resistance, would enable the sensitive detection of RVSD in preterm children. 8) Myocardial strain, indicating changes in the length of myocardial fibers, 9) is more sensitive in detecting early myocardial changes among preterm infants than are conventional echocardiographic parameters. 10) We speculated that strain parameters could sensitively detect the progression of potential RVSD among preterm children.…”

BackgroundTo 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).MethodsRetrospective 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).ResultsIn 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.ConclusionIn asymptomatic preterm children, routine echocardiographic screening using VVI could detect RVSD which could progress from 4–24 month corrected age.

“…In contrast, the LV function of the extremely preterm infants did not change significantly during the first week of life. 11,12 Infants with BPD and/or pulmonary hypertension had evidence of abnormal RV strain and RV fractional area change 18,19 but LV strain was not affected. 18 Levy et al 18 also reported maturation of RV, LV, and septal myocardial strains in uncomplicated preterm infants was associated with increasing weight and postnatal age.…”

Aim Preterm births and respiratory distress syndrome (RDS) are associated with pulmonary vascular disease and altered myocardial function. We serially assessed up to 1 year of age the effects of RDS on global and regional myocardial function of preterm infants, compared to preterm and term controls using conventional echocardiography parameters, tissue Doppler velocities and deformation analysis. Methods and results A total of 120 infants (30 preterm [PT] with RDS, 30 PT controls without RDS, and 60 term controls) underwent conventional and tissue Doppler echocardiography within 72 hours of birth, at corrected term age for the preterm infants, at 1 month corrected, and at 1 year corrected age. At birth, compared to preterm and term controls, the PT‐RDS group had decreased right ventricular (RV) long‐axis function, systolic velocity, peak systolic strain, shorter pulmonary arterial acceleration time (PAAT), and lower ratio of PAAT to RV ejection time (PAAT:RVET). Preterm infants had left ventricular (LV) diastolic dysfunction at birth (lower early diastolic myocardial velocity, mitral E velocity, and mitral E:A ratio), and reduced long‐axis systolic velocities and shortening. Differences between groups disappeared by 1 month corrected age, except PAAT:RVET which remained lower in the PT‐RDS group. At 1 year, RV function was normal in PT‐RDS apart from systolic strain rate, and LV function was normal apart from lower stroke volume and shortening, relative to body weight. Conclusion PT‐RDS had lower left and right ventricular systolic and diastolic function at birth which improved over time, suggesting postnatal maturation of cardiac function and resolution of lung disease.

“…By analyzing myocardial strain, a parameter that indicates percentage of change in the length of myocardial fibers, 6) systolic and diastolic dysfunction in children in the acute phase of KD has been assessed. 7) 8) 9) Myocardial strain can be assessed with velocity vector imaging, a technique using endocardial contour tracking to determine cardiac function.…”

BACKGROUNDSequential changes in left ventricular (LV) systolic function over time in patients with recurrent episodes of Kawasaki disease (KD) remain unclear.METHODSTwenty-five children with recurrent KD were retrospectively studied. Using conventional echocardiographic parameters and myocardial deformation analysis, systolic LV function in children in initial and recurrent KD episodes were compared with separate control groups, comprising 15 controls each. Recurrent KD was defined as occurring at an interval of ≥2 months between the initial and recurrent episodes.RESULTSThe interval range between initial and recurrent episodes of KD was 3–103 months. In children with KD, 8 (32%) were <1 year of age at the initial episode, 10 (40%) had a recurrence within 1 year of the initial episode, and 4 (16%) and 5 (20%) were intravenous immune globulin nonresponders in initial and recurrent episodes, respectively. In both the initial and recurrent episodes of KD, the mean LV longitudinal peak systolic ε was all within normal range. However, when compared to controls, mean LV longitudinal peak systolic ε was decreased in patients with KD in the acute phases of both the initial and recurrent episodes. When compared to controls, mean LV longitudinal peak systolic ε was decreased in patients with KD in the convalescent phase of the recurrent episodes.CONCLUSIONSSubclinical decreases in myocardial systolic deformation, as evidenced by decreased LV longitudinal peak systolic ε, may persist in children in the convalescent phase of recurrent KD; further studies involving larger numbers of patients may be needed for verification.
