A rare case of straddling tricuspid valve in a child with pulmonary atresia was successfully treated. This condition, without interventricular communication, presented unique surgical challenges.

Area of Science:

Cardiology
Pediatric Cardiology
Congenital Heart Disease

Background:

Pulmonary atresia is a severe congenital heart defect.
A straddling tricuspid valve is a rare anomaly where the valve straddles the ventricular septum.
Absence of interventricular communication in this context presents unique anatomical challenges.

Observation:

A four-year-old girl presented with pulmonary atresia and a straddling tricuspid valve.
The tricuspid valve had two distinct orifices, connecting to both the right and left ventricles.
Crucially, valve tissue sealed the ventricular septum, preventing an interventricular communication.

Findings:

The straddling tricuspid valve's unique anatomy, with dual orifices and septal sealing, was identified.

Surgical intervention was performed to address the complex congenital heart defect.

The surgical correction resulted in a satisfactory clinical outcome for the patient.

Implications:

This case highlights the importance of precise anatomical diagnosis in complex congenital heart disease.
Successful surgical management demonstrates the feasibility of correcting such rare anomalies.
Further understanding of straddling tricuspid valve variations can inform surgical strategies and improve patient outcomes.
