Transcatheter Closure of Left Circumflex Coronary Artery to Coronary Sinus Fistula

Area of Science:

• Interventional Cardiology
• Cardiovascular Surgery
• Vascular Medicine

Background:

• Coronary artery fistula is a rare congenital or acquired cardiovascular anomaly.
• Surgical intervention has been the traditional management for coronary artery fistulas.
• Percutaneous techniques offer a less invasive alternative, particularly for high-risk surgical candidates.

Observation:

• A 65-year-old male presented with reduced left ventricular ejection fraction attributed to a left circumflex artery to coronary sinus fistula.
• The patient had a significant surgical risk profile, precluding traditional surgical repair.
• Successful percutaneous closure was achieved using 3-dimensional-shaped platinum-based bare-metal coils.

Findings:

• The case demonstrates successful percutaneous coil embolization for a distal left circumflex artery to coronary sinus fistula.
• Despite the distal location and risk of side branch occlusion, the procedure was technically successful.
• Percutaneous closure of coronary artery fistulas demonstrates high success rates and low recurrence rates.

Implications:

• Percutaneous intervention is a viable and effective treatment option for selected patients with coronary artery fistulas, especially those at high surgical risk.
• The use of 3D-shaped platinum coils presents a promising tool, although off-label use necessitates further research into standardized protocols and long-term outcomes.
• Multidisciplinary heart team approach is crucial for optimizing individualized management strategies in complex cardiovascular cases.
