Closing a Right Coronary Artery Fistula Draining Into the Coronary Sinus Using a Covered Stent in the Coronary Sinus

Area of Science:

• Cardiology
• Interventional Cardiology
• Congenital Heart Disease

Background:

• Coronary artery fistulas are abnormal connections between a coronary artery and a cardiac chamber or vessel.
• Right coronary artery fistulas draining into the coronary sinus are rare but can cause significant symptoms.

Observation:

• A symptomatic patient presented with a right coronary artery fistula.
• The fistula's drainage point was identified as the coronary sinus.

Findings:

• Transcatheter closure was successfully performed by deploying a device at the fistula's drainage site.
• The deployed device effectively sealed the exit of the coronary artery fistula.

Implications:

• Transcatheter closure offers a minimally invasive treatment option for coronary artery fistulas.
• This approach can resolve symptoms and improve outcomes in patients with this rare condition.
