[RESULTS OF THE TOTAL CAVA-PULMONARY CONNECTION PROCEDURE WITH CORRECTION OF ATRIO-VENTRICULAR VALVES IN PATIENTS OF...

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology

Background:

• Single ventricle physiology presents complex surgical challenges.
• Atrioventricular valve insufficiency is a common complication after total cavopulmonary connection (TCPC).

Purpose of the Study:

• To enhance patient management following TCPC with atrioventricular valve (AVV) insufficiency.
• To evaluate the outcomes of complex AVV repair strategies in single ventricle patients.

Main Methods:

• Analysis of immediate and middle-term results in 132 patients who underwent TCPC from 2005-2015.
• Focus on a subgroup of 24 patients with moderate to severe systemic AVV insufficiency.
• Application of multiple plasty procedures, including fiber ring stabilization, for AVV correction.

Main Results:

• Successful early and middle-term outcomes were achieved in 92% of the selected patient cohort.
• Multiple reconstructive procedures were necessary in 8 patients undergoing AVV correction.
• Complex surgical strategies, particularly fiber ring stabilization, correlated with optimal results.

Conclusions:

• A comprehensive surgical approach combining various plasty techniques is crucial for optimal AVV correction in TCPC patients.
• Fiber ring stabilization techniques significantly contribute to achieving superior outcomes in managing AVV insufficiency.
• Improved patient management strategies can lead to better long-term results for single ventricle physiology.
