Longitudinal Intracardiac Right Ventricular Flow Analysis in Infants With Hypoplastic Left Heart Syndrome in Interstage I Using Novel Doppler Velocity Reconstruction.

ABSTRACT:

Background

Echocardiography provides noninvasive frontline assessment of right ventricular (RV) function in hypoplastic left heart syndrome (HLHS). However, conventional metrics do not quantify RV intracardiac hemodynamics. A novel Doppler velocity reconstruction measures kinetic energy, vortex strength, and flow energy loss through conventional color Doppler acquisitions. We investigated longitudinal changes in RV intracardiac flow in infants with HLHS during the critical interstage period, hypothesizing that these trends may inform disease progression.

Methods

This was a single-center, retrospective analysis of patients with HLHS who underwent stage 1 palliation (bilateral pulmonary artery bands/hybrid palliation or Norwood operation). Echocardiographic studies at 5 time p
