Relationship of pulmonary artery size and venovenous collaterals during staged single ventricle reconstruction and their impact on outcomes after Fontan procedure.

ABSTRACT:

Objectives

This study aimed to evaluate the relationship between pulmonary artery size and venovenous collaterals (VVCs) during staged single ventricle reconstruction.

Methods

Patients who underwent staged Fontan palliation between 2003 and 2023 were reviewed. The relationship between the pulmonary artery index and the development of VVCs was determined. Furthermore, the impact of pulmonary artery index and VVCs on in-hospital morbidities after the Fontan procedure was evaluated.

Results

A total of 377 patients were included. Median age at bidirectional cavopulmonary shunt (BCPS) and total cavopulmonary connection (TCPC) were 4.2 (3.3-6.2) months and 2.1 (1.7-2.6) years, respectively. VVCs were observed in 51 (13.5%) of the patients. Patients who developed VVCs showed
