Summary
Preoperative cardiac function, including left ventricular ejection fraction (LVEF), was better in patients who survived total anomalous pulmonary venous connection repair. Post-operative performance in survivors was generally normal.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Congenital Heart Disease
Context:
- Total anomalous pulmonary venous connection (TAPVC) is a complex congenital heart defect.
- Surgical repair outcomes are influenced by preoperative cardiac status.
- Understanding predictors of survival is crucial for patient management.
Purpose:
- To evaluate cardiac performance before and after surgical repair in TAPVC patients.
- To identify preoperative indicators of surgical survival.
- To assess postoperative cardiac function in survivors.
Summary:
- Cardiac catheterization was performed on 54 TAPVC patients pre- and post-surgery.
- Survivors had significantly higher preoperative left ventricular ejection fraction (LVEF) and lower pulmonary arterial pressure compared to non-survivors.
- Postoperative LVEF and left ventricular end-diastolic volume (LVEDV) improved, while right ventricular ejection fraction (RVEF), RVEDV, and pulmonary arterial pressure decreased.
Impact:
- Preoperative cardiac function is a significant predictor of mortality in TAPVC repair.
- Surgical repair leads to improved left ventricular function and normalized hemodynamics in survivors.
- Findings inform risk stratification and surgical decision-making for TAPVC patients.
