Overview

Randomized trial evaluates right ventricular volumes in children with various cardiac conditions, implying potential diagnostic insights.

Key Points

  • This research aims to quantify right ventricular (RV) volumes in children using cineangiocardiography and examine their differences across age and cardiac conditions.
  • 46 patients underwent cardiac catheterization with biplane cineangiocardiography.
  • Comparison of calculated RV volumes to postmortem casts and stroke volumes.
  • Data analysis included children with normal hearts, pulmonary stenosis, and atrial septal defect.
  • Infants showed significantly smaller RV end-diastolic volumes compared to older children (39 ± 8 vs 70 ± 13 ml/m², P < 0.001).
  • Patients with isolated pulmonary stenosis had normal RV indices except for elevated RVEF/LVEF (1.13 vs 0.99, P < 0.05).
  • Atrial septal defect patients demonstrated significantly increased RV volumes and indices compared to normal values.
