Images in Cardiovascular Medicine Thrombotic Occlusion of Giant Circumflex Artery Aneurysm After Ligation of Arteriovenous Fistula

A 39-year-old man with no significant past medical history and no conventional coronary risk factors presented with a history of gradually progressive exertional dyspnea and a systolic heart murmur. Chest x-ray showed an enlarged cardiac silhouette with pulmonary plethora. Initial assessment by transthoracic echocardiography demonstrated mild mitral regurgitation but also revealed an enlarged c...

Left circumflex coronary artery aneurysm with arteriovenous fistula to the coronary sinus presenting as acute coronary syndrome.

Saccular aneurysm of congenital coronary arteriovenous fistula.

A rare aneurysm of a congenital coronary arteriovenous fistula is reported. Echocardiography showed a dilated left coronary and left circumflex artery with normal left anterior descending artery. A dilated structure near the crux was confirmed to be a large aneurysm of circumflex coronary artery on selective angiography. It drained into the posterior right atrial wall. Under cardiopulmonary byp...

Giant Left Circumflex Artery Aneurysm with Coronary Sinus Fistula

Coronary artery fistulas are a very rare cardiac anomaly. The reported Incidence of coronary artery fistula is 0.10.2% in all patients undergoing coronary angiography [1]. 26% of the patients with coronary artery fistula have associated coronary artery aneurysm. Giant coronary artery aneurysms with diameter exceeding 50 mm are extremely rare. As the aneurysm enlarges, complications related to v...

DESCRIPTION A 71-year-old man was admitted with a 2-day history of intermittent palpitations. His initial ECG demonstrated a supraventricular tachycardia with a heart rate of 170 bpm. Following treatment with verapamil he reverted to sinus rhythm. As part of his initial investigations he had a two dimensional transthoracic echocardiogram. The parasternal long axis view demonstrated a well-circu...
