Trifoliate left atrioventricular valve

Last edited: 4/15/2026

Overview

Trifoliate left atrioventricular valve, also known as Ebstein anomaly variant, is a rare congenital heart defect characterized by an abnormally positioned and malformed tricuspid valve with leaflets extending into the left ventricle, potentially leading to significant hemodynamic disturbances 1.

Diagnosis

  • Echocardiography is essential for diagnosis, revealing the malformation of the tricuspid valve and its insertion into the left ventricle 1.
  • Cardiac MRI or CT may provide additional anatomical detail and assess the extent of valvular malformation 1.
  • Hemodynamic assessment via echocardiography or catheterization to evaluate right and left ventricular function and pressures 1.

    • Management

  • Surgical repair is often indicated, involving tricuspid valve reconstruction or replacement, and addressing any associated anomalies like ventricular septal defects 1.
  • Medical management focuses on symptom control, including diuretics for fluid overload and anticoagulation if mechanical valve replacement is performed 1.
  • Postoperative care emphasizes monitoring for complications such as arrhythmias and heart failure 1.

    • Special Populations

  • Specific management strategies for pregnancy, pediatrics, elderly, or comorbidities are not addressed in the provided abstracts 1.

    • Key Recommendations

  • Confirm diagnosis primarily through echocardiography with adjunctive imaging as needed for detailed anatomy 1 (Evidence: Moderate).
  • Consider surgical intervention for significant hemodynamic compromise or valvular dysfunction 1 (Evidence: Expert opinion).
  • Tailor postoperative management to monitor and manage potential complications like arrhythmias and heart failure 1 (Evidence: Expert opinion).
