Double-outlet left ventricle: A rare case

Area of Science:

• Cardiology
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Double-outlet left ventricle (DOLV) is a rare congenital heart malformation with significant associated mortality.
• Patients with DOLV often experience complications like heart failure, myocardial infarction, and aortic thrombosis.
• Surgical intervention offers a 5-year survival rate of 70%-75%, but residual anomalies are common.

Observation:

• A 25-year-old male diagnosed with DOLV, pulmonary stenosis, and patent ductus arteriosus presented with hemoptysis.
• The hemoptysis was attributed to a concurrent respiratory tract infection.
• The patient received standard medical therapy for the infection.

Findings:

• The patient's hemoptysis resolved completely following standard treatment for the respiratory tract infection.
• This case highlights the importance of considering non-cardiac causes for presenting symptoms in patients with complex congenital heart disease.
• Successful management of acute symptoms, even in the presence of underlying cardiac anomalies, is achievable.

Implications:

• This case underscores the need for comprehensive diagnostic evaluation in patients with DOLV, considering both cardiac and non-cardiac etiologies for symptoms.
• Effective management of intercurrent illnesses can lead to favorable outcomes in individuals with complex congenital heart defects.
• Further research into the long-term management strategies for DOLV patients presenting with diverse clinical scenarios is warranted.
