Abstract

Objectives:

The purpose of this study was to report outcomes of double outlet right ventricle biventricular repair at a single institution in developing countries and to investigate post-operatively determined risk factors for mortality and late intervention.

Methods:

Patients with double outlet right ventricle who underwent biventricular repair in our centre from January 2009 to December 2021 were included.

Results:

A total of 96 patients (male/female = 61/35) with biventricular repair were included. According to its specific anatomical type, the appropriate individual surgical plan was selected. Multivariate analysis indicated that prolonged cardiopulmonary bypass time(OR = 1.044; p = 0.012) and pre-operative moderate or above pulmonary hypertension(OR = 24.558; p = 0.023) were independent risk factors for early mortality. Univariate analysis showed that different anatomical types and different surgical methods had similar late intervention and late mortality. Concomitant coarctation of the aorta(OR = 40; p = 0.020) and concomitant ventricular septal defect enlargement(OR = 26.667; p = 0.005) were independent risk factors for late intervention by multivariate analysis.

Conclusion:

Selection of appropriate surgical techniques based on different anatomical types often results in similar late outcomes. For patients with concomitant ventricular septal defect enlargement during the operation, it is necessary to fully expand and avoid damage to the conduction bundle. We should timely intervention in patients with coarctation of the aorta and pay attention to the occurrence of left ventricular outflow tract obstruction during follow-up.
