# Complex Presentation of Congenital Heart Block and Coexisting Congenital Heart Disease in a One-Year-Old Girl: A Case Report

## TL;DR

A one-year-old girl with congenital heart block and heart disease showed symptoms requiring careful evaluation and management.

## Contribution

This case report highlights the complex clinical presentation and management of congenital heart block in a pediatric patient.

## Key findings

- The patient exhibited CCHB and congenital heart disease with dilated chambers and ventricular septal defect.
- Serological tests for maternal autoantibodies were negative, indicating an alternative etiology.
- The case emphasizes the need for comprehensive evaluation in managing congenital heart block.

## Abstract

Congenital complete heart block (CCHB) is a rare and potentially life-threatening condition, often associated with maternal autoantibodies. We present the case of a one-year-old girl with recurrent respiratory symptoms, ultimately diagnosed with CCHB and congenital heart disease. She exhibited bradycardia and signs of congestive heart failure. A diagnostic workup revealed significant cardiac abnormalities, including dilated chambers, ventricular septal defect, and patent ductus arteriosus. Serological tests for maternal autoantibodies were negative. The child’s parents opted for discharge without surgical intervention. This case underscores the importance of comprehensive evaluation and management strategies in patients with congenital heart block, particularly in resource-limited settings.
