Objective:
Different surgical approaches have been used to repair complete atrioventricular septal defects (AVSD). Regurgitant atrioventricular valves (AV-valves) are common after surgery. We compared different surgical techniques with respect to long-term postoperative AV-valve regurgitation.
Methods:
In 69 patients with complete AVSD, three different surgical techniques were applied: Single-patch, two-patch, and modified techniques. The left-sided AV-valve cleft was surgically closed in all patients.
Results:
A comparison of the results of the different techniques showed no difference in the degree of AV-valve regurgitation on either the right or the left side. The average degree was mild on both sides. Only one patient needed reoperation for severe left-sided AV-valve regurgitation.
Conclusion:
The different surgical techniques used for the correction of AVSD do not have a major bearing on the degree of AV-valve regurgitation.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
