# Case Report: Neonatal heart failure: a rare presentation of congenital left ventricular aneurysm

## TL;DR

A rare case of congenital left ventricular aneurysm in a neonate led to heart failure and sudden death despite treatment.

## Contribution

This case report highlights the management challenges and potential outcomes of a rare cardiac condition in neonates.

## Key findings

- The patient had a genetic test suggesting pyruvate dehydrogenase complex deficiency.
- The infant showed reduced cardiac output and was treated with antifailure medications.
- The patient died at 6 months, likely due to sudden cardiac death.

## Abstract

Congenital left ventricular aneurysm is a rare condition. Most patients remain asymptomatic for long periods. However, it carries a significant risk of serious complications, and management approaches are not well documented in the literature. We share our experience with an infant who had a positive genetic test indicating possible autosomal recessive pyruvate dehydrogenase complex deficiency with a non-specific cardiac association. The patient showed reduced cardiac output, received intensive treatment with antifailure medications, and was placed under close clinical observation, with nutritional improvement in preparation for surgical aneurysmectomy. Unfortunately, he was found dead at 6 months of age, possibly due to sudden cardiac death.
