Summary
This study analyzed double-inlet ventricle anatomy in Chinese patients, finding double-inlet right ventricle most common, unlike other populations. Right atrial isomerism frequently accompanied this condition.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Double-inlet ventricle is a rare congenital heart defect.
- Understanding its prevalence and associated anomalies is crucial for diagnosis and treatment.
Purpose of the Study:
- To elucidate the anatomic features of double-inlet ventricle in the Chinese population.
- To compare findings with international data.
Main Methods:
- Retrospective analysis of echocardiograms from 60 Chinese patients with double-inlet ventricle.
- Detailed review of atrial connections, ventricular dominance, and associated anomalies.
Main Results:
- Double-inlet right ventricle was the predominant type (60%), contrasting with other reports.
- Right atrial isomerism was highly prevalent (83% with DIV), especially with double-inlet right and indeterminate ventricles.
- Common atrioventricular valve and double-outlet main chamber were frequent associations.
Conclusions:
- Double-inlet right ventricle is the predominant form in the Chinese population studied.
- High association with right atrial isomerism may explain the discrepancy with other populations.
- Further research into ethnic variations of congenital heart defects is warranted.
