Overview
Endocardial cushion defect (ECD) encompasses congenital malformations involving the atrioventricular (AV) canal, often classified as complete or partial, and can occur in isolation or as part of a syndrome. 1Diagnosis
Key Diagnostic Criteria: Identification of AV canal defect, differentiation between complete and partial forms.
Recommended Tests: Echocardiography for definitive diagnosis, assessing extent and associated anomalies.
Associated Anomalies: Syndromic ECD often complete AV canal type; isolated ECD linked with gastrointestinal and urinary tract anomalies. 1Management
First-Line Treatment: Surgical repair for both isolated and syndromic cases, timing based on patient condition.
Adjunctive Therapies: Postoperative management includes monitoring for arrhythmias and heart failure.
Specific Considerations: In Down syndrome, ECD management focuses on cardiovascular aspects independent of other trisomic manifestations. 1Special Populations
Down Syndrome: ECD management tailored to cardiovascular needs without direct correlation to other noncardiac malformations. 1
Other Syndromes: Unique cardiovascular phenotypes require syndrome-specific considerations in management. 1Key Recommendations
Differentiate between isolated and syndromic ECD for tailored management strategies (Evidence: Moderate) 1
Echocardiography is essential for diagnosis and assessing the extent of ECD and associated anomalies (Evidence: Moderate) 1
Surgical repair is indicated for both isolated and syndromic ECD, with timing influenced by patient-specific factors (Evidence: Expert opinion) 1References
