Fermeture percutanée d'une fistule coronaro-pulmonaire : à propos d'un cas

Background

A coronary artery fistula is an abnormal connection between one or more coronary arteries and a cardiac chamber or great vessel, often discovered incidentally through cardiac imaging. Although coronary artery fistulas are typically asymptomatic during the first two decades of life, particularly when small, they can become clinically significant over time.

Case presentation

We present the case of a 71-year-old female patient with a history of exertional dyspnea. Diagnostic coronary angiography revealed a significant coronary artery fistula originating from the proximal right coronary artery and draining into the pulmonary artery trunk. Given the patient's symptoms and the anatomical features of the fistula, she was successfully treated with transcutaneous closure using a liquid embolic agent (Onyx).

Conclusion

Although surgical intervention has historically been the primary treatment for CAF, minimally invasive techniques such as transcutaneous closure are proving to be effective alternatives.
