Key Result

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.

Key Points

To report a rare case of congenital left ventricular aneurysm leading to neonatal heart failure and explore management challenges.
Documented the patient's clinical presentation and management approaches
Performed genetic testing for pyruvate dehydrogenase complex deficiency
Administered antifailure medications and monitored closely before surgery
The infant exhibited reduced cardiac output and required intensive treatment
Despite close clinical observation, the infant unfortunately died at 6 months
Possible cause of death identified as sudden cardiac death linked to the condition

Study Design

Type

Case Report (n=1)

Multicenter

Structured PICO

Population

1 male infant born at 36 weeks gestation (birth weight 2 kg) to consanguineous parents, presenting with neonatal heart failure due to a congenital left ventricular apical aneurysm and a positive genetic test for possible autosomal recessive pyruvate dehydrogenase complex deficiency.

Intervention

Medical management for heart failure (furosemide, captopril) and clinical observation for weight gain prior to planned surgical aneurysmectomy.

Outcome

Clinical outcome and survival at 6 months of agehard clinical

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.

Limitations

Single case report with no comparative analysis.

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.
