A rare coexistence: Hammock mitral valve and aortopulmonary window

Area of Science:

• Pediatric Cardiology
• Congenital Heart Disease Surgery

Background:

• Congenital mitral stenosis, including hammock mitral valve, obstructs left ventricular blood flow.
• Aortopulmonary window is a rare anomaly requiring prompt surgical closure to prevent pulmonary hypertension.

Purpose of the Study:

• To describe a simultaneous surgical approach for a complex congenital heart defect in an infant.
• To highlight the management of a rare hammock mitral valve combined with an aortopulmonary window.

Main Methods:

• Simultaneous surgical repair in a 5-month-old infant.
• Mitral valve replacement with a mechanical valve.
• Repair of the aortopulmonary window using a Dacron patch.

Main Results:

• Successful simultaneous repair of both congenital anomalies.
• The infant tolerated the complex procedure well.

Conclusions:

• Simultaneous surgical correction is feasible for combined hammock mitral valve and aortopulmonary window.
• Early intervention is crucial for managing these severe congenital cardiac defects.
