Long-Term Follow-Up of a Nonprogressive Left Main Coronary Artery Fistula to Right Atrium

Coronary artery fistula is a rare cardiac abnormality, occurring more frequently in young patients and treated with cardiac surgery or percutaneous interventions in most cases. We present the case of a 63-year-old man with an incidental diagnosis of coronary artery fistula, treated with conservative strategy. (Level of Difficulty: Intermediate.).

Multivessel Coronary Artery Disease in a Patient With Noncompaction Cardiomyopathy With Coronary Artery-to-Left Ventricle Fistulas

Coexistence of coronary artery-to-left ventricle fistula (CALVF) and noncompaction cardiomyopathy (NCC) is rare in patients with severe multiple coronary stenosis. We report CALVF in a 70-year-old man with acute coronary syndrome (ACS) and NCC. Left ventricular ejection fraction may not improve by total revascularization in this condition. (Level of Difficulty: Advanced.).

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

This report describes the case of a symptomatic patient with a right coronary artery fistula draining into the coronary sinus who underwent transcatheter closure, which was deployed in the drainage site to seal off the exit of the fistula. (Level of Difficulty: Advanced.)

A Rare Case of Coronary Artery Dilatation and Giant Pseudoaneurysm

Coronary artery fistula are anomalous connections with coronary vessels or cardiac chambers, potentially resulting in coronary dilatation and pseudoaneurysm formation. We present the case of a 68-year-old woman referred to our institution for a voluminous coronary pseudoaneurysm secondary to coronary artery fistula presenting as a nearly completely obstructive left atrial mass. (Level of Difficulty: Intermediate.).

A Continuous Murmur as the Only Clinical Sign for Complex Coronary Artery Fistulas Diagnosis

An asymptomatic patient presented at our hospital exhibiting a Brugada electrocardiography pattern with coronary artery fistulas. Coronary artery fistula is a congenital or acquired rare abnormal condition with increased symptoms and complications over time. In the absence of the therapeutic consensus, we discuss the association and management for this condition. (Level of Difficulty: Advanced.).

Unusual Case of Giant Nonthrombosed Right Coronary Artery Pseudoaneurysm With Coronary Artery Fistula

Coronary artery aneurysm and pseudoaneurysm are rare and mainly result from atherosclerosis. We present a successfully treated case of a giant right coronary artery aneurysm and pseudoaneurysm with a coronary artery fistula, which might have developed after cardiac surgery for a right ventricular tumor 35 years earlier. (Level of Difficulty: Advanced.).

Percutaneous Coil Embolization of Confluent Bilateral Coronary Artery Fistulas

A 52-year-old woman presented with a continuous heart murmur at an annual health examination. Coronary computed tomography angiography showed confluent coronary artery fistulas meeting to form a large aneurysm fistulizing to the pulmonary artery. Percutaneous coil embolization was performed, resulting in the disappearance of the coronary artery fistulas and aneurysms. (Level of Difficulty: Intermediate.).
