Giant right coronary artery aneurysm

Abstract

Coronary artery aneurysm (CAA) is defined as dilatation of the coronary artery that is more than 1.5 times the diameter of normal adjacent segments. A coronary artery with a diameter more than 2 cm is termed as 'giant aneurysm' and only a few cases have been described in the literature. In adults, CAA is predominantly atherosclerotic in origin; however, other causes include Kawasaki disease, autoimmune disease, trauma, infection, dissection, congenital malformation and angioplasty. Clinical presentation, prognosis and management of a giant CAA are not well defined due to limited experience. We present the case of a patient with giant aneurysm of the proximal segment of the right coronary artery.

Cardiac tamponade due to rupture of a right coronary artery aneurysm in a patient with Behçetʼs disease

“…Vascular involvement is seen in 7-29% of patients. [1][2][3][4][5][6][7][8][9][10][11][12] Coronary arterial involvement in Behçet's disease, including aneurysms, is quite rare, but it has life-threatening complications. Here, a 37-year-old male patient with Behçet's disease who had acute cardiac tamponade due to rupture of a right coronary artery (RCA) aneurysm is presented.…”

A rare case of giant coronary artery aneurysm in the context of multiple arterial aneurysms

“…1 'Giant' CAA defined as greater than 2 cm and is a rare diagnosis. 2 The presence of CAA was first recognised in post-mortem studies, including a series of 694 patients by Daoud et al 3 where the incidence of coronary aneurysm was reported as 1.4%. The largest ante-mortem series of CAA from the Coronary Artery Surgery Study (CASS) registry reported an incidence of 4.9% as diagnosed by coronary angiography, 4 with the published incidence of CAA on coronary angiography varying between 1.5% and 5%.…”

Successful management of a huge thrombus in coronary aneurysmatic dilatation after failed mechanical thrombectomy during acute myocardial infarction

“…1,2 CAA is defined as a localized dilatation of the coronary artery exceeding the diameter of adjacent normal segment by more than 50%. 3 In adults, CAA is predominantly atherosclerotic in origin; however, other causes include Kawasaki disease, infection, trauma, dissection, congenital malformation and angioplasty. 3,4 The presence of an aneurysm of the IRA filled with heavy thrombus represents a challenge for the interventional cardiologist because of a high rate of thrombus embolization and no reflow following PCI.…”

“…3 In adults, CAA is predominantly atherosclerotic in origin; however, other causes include Kawasaki disease, infection, trauma, dissection, congenital malformation and angioplasty. 3,4 The presence of an aneurysm of the IRA filled with heavy thrombus represents a challenge for the interventional cardiologist because of a high rate of thrombus embolization and no reflow following PCI. Direct stenting without predilatation may decrease embolization and the incidence of the no reflow.…”
