Summary
This study describes two patients with rare coexisting heart defects: complete atrioventricular canal and cor triatriatum. Surgical correction was challenging due to the primary defect and an undiagnosed secondary condition.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Pediatric Cardiac Surgery
Background:
- Complete atrioventricular canal (CAVC) is a complex congenital heart defect.
- Cor triatriatum is a rare cardiac anomaly involving an accessory membrane dividing the left atrium.
- The co-occurrence of CAVC and cor triatriatum is exceptionally uncommon.
Purpose of the Study:
- To describe the clinical presentation and surgical outcomes of two patients with the rare combination of complete atrioventricular canal and cor triatriatum.
- To highlight the challenges associated with diagnosing and managing this dual cardiac defect.
Main Methods:
- Case report of two pediatric patients.
- Surgical intervention for congenital heart defects.
- Postoperative assessment of outcomes.
Main Results:
- Two patients presented with complete atrioventricular canal and coexisting cor triatriatum.
- Surgical correction was primarily limited by the complexity of the atrioventricular valve reconstruction in CAVC.
- Undiagnosed cor triatriatum posed intraoperative difficulties.
Conclusions:
- The combination of complete atrioventricular canal and cor triatriatum is rare and likely arises from unrelated embryological origins.
- Surgical success in such cases is predominantly dictated by the management of the more severe defect, in this instance, the complete atrioventricular canal.
- Preoperative diagnosis of all coexisting anomalies is crucial for optimal surgical planning and patient outcomes.
