[Successful correction of arterial fistula between coronary arteries and pulmonary trunk]

Area of Science:

• Cardiology
• Congenital Heart Disease
• Vascular Surgery

Background:

• Congenital heart disease encompasses a range of structural abnormalities present at birth.
• Coronary artery fistulas are uncommon, involving abnormal connections between a coronary artery and another heart chamber or major vessel.
• Pulmonary artery fistulas can lead to significant hemodynamic alterations and require timely intervention.

Observation:

• A case of congenital heart disease was incidentally diagnosed during a routine medical examination.
• The specific anomaly identified was a fistula connecting the left coronary artery to the right pulmonary artery and the right coronary artery to the pulmonary trunk.
• This diagnosis highlights the potential for asymptomatic presentation of complex congenital cardiac anomalies.

Findings:

• Diagnostic imaging confirmed the presence of complex coronary artery fistulas involving both major coronary arteries and the pulmonary trunk/right pulmonary artery.
• Surgical intervention was performed utilizing cardiopulmonary bypass and warm blood cardioplegia.
• The corrective surgery successfully disconnected the abnormal fistulous connections between the coronary arteries and the pulmonary arteries.

Implications:

• Accidental diagnosis underscores the importance of thorough medical evaluations, even in asymptomatic individuals.
• Successful surgical correction demonstrates the efficacy of established surgical techniques for complex coronary artery fistulas.
• This case contributes to the understanding and management strategies for rare congenital heart anomalies.
