Congenital left ventricular aneurysm can present as neonatal heart failure and carries a significant risk of sudden cardiac death, highlighting the challenges in timing surgical intervention.
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.
Alsuayyid et al. (2026) conducted a case report in Congenital left ventricular aneurysm (n=1). intensive treatment with antifailure medications was evaluated on death possibly due to sudden cardiac death. The infant diagnosed with congenital left ventricular aneurysm and treated for heart failure was found dead at 6 months of age, possibly due to sudden cardiac death.
