Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Context:

• Mustard's operation for congenital heart defects can lead to serious venous inflow stenoses.
• Pulmonary and systemic venous stenoses are significant complications requiring innovative solutions.

Purpose:

• To present two modified atrial inversion techniques for preventing venous stenosis after Mustard's operation.
• To reduce the need for foreign materials in atrial switch procedures.

Summary:

• Two novel atrial inversion methods incorporate native atrial tissue into the new septum, minimizing foreign material use.
• Method I uses a Dacron patch for fragile atrial tissue, while Method II utilizes a right atrial flap for normal tissue.
• Both techniques aim to prevent secondary stenoses by integrating growing tissues, reducing risks associated with shrinkage or fibrous pannus.

Impact:

• These techniques offer improved outcomes by reducing the incidence of critical venous stenosis post-Mustard's operation.
• Minimizing foreign material may decrease long-term complications and reinterventions in patients with complex congenital heart disease.
