Dataset Information

Genotypic and phenotypic predictors of complete heart block and recovery of conduction after surgical repair of congenital heart disease.

ABSTRACT:

Background

Complete heart block (CHB) is a major complication that occurs after congenital heart surgery. We hypothesized that genetic and clinical factors are associated with the development of postoperative CHB and recovery of atrioventricular (AV) conduction.

Objective

The purpose of this study was to identify predictors of CHB and recovery after congenital heart surgery.

Methods

Patients undergoing congenital heart surgery at our institution from September 2007 through June 2015 were prospectively enrolled in a parent study of postoperative arrhythmias. Patients with onset of CHB within 48 hours postoperatively were included in the study. Daily rhythm assessment was performed until demonstration of 1:1 conduction or pacemaker implantation.
