Complete atrioventricular canal: current surgical technique

Area of Science:

• Pediatric Cardiac Surgery
• Congenital Heart Defects
• Cardiovascular Surgery

Background:

• Complete atrioventricular canal (CAVC) is a complex congenital heart defect.
• Current surgical repair often involves complex patch work and valve management.
• Standard techniques aim to restore normal cardiac anatomy and function.

Purpose of the Study:

• To describe and evaluate a specific surgical technique for CAVC repair.
• To assess the feasibility of using two patches and an undivided common atrioventricular valve.
• To report outcomes in a cohort of pediatric patients undergoing this repair.

Main Methods:

• Surgical repair of complete atrioventricular canal using two separate patches.
• The common atrioventricular valve is intentionally left undivided.
• The anterior mitral leaflet cleft is left unsutured to form a trileaflet mitral valve.
• Technique applied to 10 patients (9 Type C, 1 Type A) aged 6 months to 4.5 years.

Main Results:

• The described technique was successfully applied in 10 pediatric patients.
• The repair involved specific patch placement for atrial and ventricular septal closure.
• The common atrioventricular valve and mitral valve cleft were managed as described.

Conclusions:

• The described surgical technique offers a method for complete atrioventricular canal repair.
• This approach utilizes specific patch configurations and valve management strategies.
• Further studies are needed to evaluate long-term outcomes of this technique.
