Insights

Right ventricle (RV) strain measured by echocardiography is feasible in preterm infants. While RV function was worse in Bronchopulmonary dysplasia (BPD) patients, RV strain differences were not conclusive, requiring further research.

Area of Science:

  • Pediatric Cardiology
  • Neonatology
  • Echocardiography

Background:

  • Bronchopulmonary dysplasia (BPD) poses a significant risk for secondary right ventricle (RV) failure in preterm infants.
  • Early detection of RV dysfunction is crucial for managing BPD complications.
  • Speckle tracking echocardiography offers a potential method for assessing RV deformation.

Purpose of the Study:

  • To evaluate the feasibility and diagnostic utility of RV strain analysis using speckle tracking in preterm infants.
  • To compare RV strain and conventional function parameters between infants with and without BPD.
  • To investigate the trend of RV strain over the first year of life in relation to BPD.

Main Methods:

  • Prospective longitudinal study over 28 months at a pediatric cardiology center.
  • Inclusion of preterm infants (<32 weeks gestational age) divided into NO-BPD and BPD groups.
  • Echocardiogram measurements, including RV strain via speckle tracking, performed at three timepoints in the first year of life.

Main Results:

  • Fifty infants enrolled (22 NO-BPD, 28 BPD).
  • No statistically significant differences in RV strain between the NO-BPD and BPD groups.
  • The BPD group exhibited poorer RV function based on both speckle tracking and conventional parameters.
  • A trend towards improvement in RV strain was observed during follow-up.

Conclusions:

  • RV longitudinal strain and strain rate assessment via speckle tracking is feasible in preterm infants.
  • While a correlation between RV strain and BPD severity is suggested, this study's findings were inconclusive.
  • Further research is needed to establish an optimal echocardiographic screening model for RV dysfunction in BPD patients.
