Asymptomatic Giant Traumatic Right Coronary Artery Pseudoaneurysm Caused by Sternal Fracture

An Extremely Large Coronary Aneurysm Associated with a Quadricuspid Aortic Valve in an Adult Patient

“…Coronary artery aneurysms may be caused by coronary arteritis, congenital malformations, postcoronary interventions and chest trauma (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). The aneurysm in the present case was associated with coronary pulmonary artery fistulas and had a short trunk measuring 2-3 mm in length branching from the left anterior descending coronary.…”

“…The etiology of coronary aneurysms involves congenital malformation, atherosclerosis, chest trauma, Kawasaki disease, sarcoidosis, Behcet's disease, systemic lupus erythematosus, directional coronary atherectomy and postimplantation of a drug-eluting stent (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Coronary artery fistulas are a common congenital disease that is often combined with giant coronary aneurysms (13).…”

Fatal delayed cardiac tamponade due to rupture of micropseudoaneurysm of left anterior descending coronary artery following stab to the chest

“…Coronary pseudoaneurysm is much less common than true aneurysm and usually occurs after catheter-based coronary intervention as a result of traumatic dissection or perforation of the coronary artery [1,3]. Coronary artery pseudoaneurysm can also occur spontaneously, due to blunt chest trauma, and in association with cardiac tumors [1,3]. However, isolated penetrating injury of a coronary artery causing coronary pseudoaneurysm and fatal delayed cardiac tamponade is very rare.…”

“…It is classified as true or false (pseudo) based on the respective presence or absence of all three layers (intima, media, and adventitia) in the wall of the aneurysm [2]. Coronary pseudoaneurysm is much less common than true aneurysm and usually occurs after catheter-based coronary intervention as a result of traumatic dissection or perforation of the coronary artery [1,3]. Coronary artery pseudoaneurysm can also occur spontaneously, due to blunt chest trauma, and in association with cardiac tumors [1,3].…”

“…Coronary artery aneurysm is rare in adult patients, and atherosclerosis is the most common cause followed by inflammation, infections, and connective tissue disorders [1]. It is classified as true or false (pseudo) based on the respective presence or absence of all three layers (intima, media, and adventitia) in the wall of the aneurysm [2].…”
