Modified Tran Viet-Neveux technique with monocusp valve for truncus type 1 repair

Area of Science:

• Congenital Heart Surgery
• Pediatric Cardiology
• Thoracic Surgery

Background:

• Restoring right ventricle to pulmonary artery (RV-PA) continuity is crucial in truncus arteriosus repair.
• Current surgical strategies, primarily valved conduits, face challenges with long-term durability and reoperation rates.
• Avoiding conduit implantation is suggested to improve outcomes and reduce the need for subsequent surgeries.

Purpose of the Study:

• To present a modified surgical technique for RV-PA continuity restoration in truncus arteriosus.
• To evaluate the feasibility of using a monocusp valve within a modified Tran Viet-Neveux repair.
• To highlight potential benefits of avoiding traditional valved conduit implantation.

Main Methods:

• Description of a modified Tran Viet-Neveux surgical technique.
• Incorporation of a monocusp valve for RV-PA continuity.
• Application in a 3-month-old infant diagnosed with truncus type 1.

Main Results:

• Successful implementation of the modified surgical repair in the patient.
• Demonstration of a viable alternative to standard valved conduits.
• Potential for improved long-term outcomes by avoiding conduit implantation.

Conclusions:

• The modified Tran Viet-Neveux technique with a monocusp valve is a feasible approach for RV-PA continuity in truncus arteriosus.
• This method may offer an alternative to traditional valved conduits, potentially leading to longer freedom from reoperation.
• Further studies are warranted to confirm the long-term efficacy and safety of this surgical innovation.
