Challenging surgery of giant right coronary aneurysm associated with coronary sinus fistula

Area of Science:

• Cardiology
• Congenital Heart Disease
• Vascular Surgery

Background:

• Coronary artery fistula (CAF) is a rare anomaly with abnormal coronary artery connections.
• These fistulas can lead to coronary artery dilation and hemodynamic disturbances.
• Treatment options range from transcatheter to surgical interventions.

Observation:

• A rare case of coronary artery fistula involving an extremely dilated giant right coronary artery was observed.
• The fistula connected the coronary artery to the coronary sinus.
• The patient's complex anatomy necessitated a specific surgical approach.

Findings:

• Surgical treatment involved the complete exclusion of the giant right coronary artery.
• A subsequent triple bypass surgery was performed to restore adequate coronary perfusion.
• This combined approach effectively managed the complex fistula.

Implications:

• This case highlights a successful surgical strategy for complex coronary artery fistulas.
• The findings contribute to the understanding of managing giant coronary artery aneurysms associated with fistulas.
• The presented technique offers a potential solution for similar challenging cardiovascular anomalies.
