Coronary artery aneurysm is a relatively uncommon disorder characterized by coronary artery dilatation with diameter that exceeds 50% of the normal adjacent segments with atherosclerosis being the most common etiology. Aneurysms can be adjacent to a stenosis in a post- or prestenotic location. Both anatomical conditions are technically challenging regarding their percutaneous treatment because ...

OBJECTIVE The is to report immunohistochemical observations of aortic α-smooth muscle actin (SMA) expressions in patients with aortic aneurysm, acute aortic dissection, and coronary artery disease and to discuss phenotypic switching of smooth muscle cells (SMCs) of these lesions. METHODS Forty-nine consecutive patients scheduled for surgical treatment for acute type A aortic dissection (20 pa...

Coronary artery aneurysms are relatively rare and commonly associated with significant coronary artery disease (CAD), inflammatory diseases (Kawasaki syndrome, infection), or iatrogenic complications. Herein, we report an unusual case of an incidental coronary aneurysm of the left main artery in a patient without specific clinical symptoms of myocardial ischemia or systemic inflammation and wit...

Fig. 1. (a) TOE, modified bicaval view, demonstrates a ‘mass’ in close association to the right atrium (white arrow), (b) TruFISP cardiac magnetic resonance demonstrates that the aneurysm (white arrow) has a perfused central lumen and there was perfusion of the distal right coronary artery, (c) multislice CT demonstrates a grossly aneurysmal saphenous vein graft with a large amount of mural thr...

A 52-year-old man with diagnosis of post-infarction unstable angina. Coronary angiography revealed 90% luminal obstruction in the middle third of the right coronary artery and 90% in the marginal branch of the circumflex artery. After the administration of clopidogrel 300 mg associated with acetylsalicylic acid, the patient underwent the implantation of a sirolimus-eluting stent (CYPHER; Johnso...

A 70-year-old man with hypertension was admitted to our coronary ICU with acute anterior MI. Emergent primary PCI was planned and coronary angiography was performed. LAD artery was totally occluded in the proximal segment just after a huge 32 × 26 mm sized aneurysm. Emergent CABG operation was performed in 75 minutes because of multivessel disease including the RCA and left circumflex artery. A...

RATIONALE Coronary artery aneurysms and fistulas are not rare conditions in clinical practice, but bilateral fistulas with a giant coronary aneurysm in just one person are quite rare. PATIENT CONCERNS We report a case of a 66-year-old woman with these 2 coronary abnormalities accompanied with a huge mediastinum mass. INTERVENTIONS The giant aneurysm was ligated and the mass was resected whi...

A thirty nine year old woman presented with ischaemic chest pain caused by a saccular aneurysm of the left coronary sinus of Valsalva. Over the next two weeks there was rapid dilatation of the aneurysm which led to left coronary artery compression and death from a massive myocardial infarction. It is suggested that early repair should be considered in patients with saccular aneurysm at this sit...

background kawasaki disease (kd) is an acute febrile vasculitis of early childhood and the leading cause of acquired heart disease in children. the most important complication of kd is coronary artery aneurysm that may lead to thrombosis and myocardial infarction, occurring in 25% of untreated cases. fortunately, timely treatment decreases it to 2 - 4%. there is no specific test for the diagnos...

Peripheral mycotic aneurysm is a rare complication of infective endocarditis. We herein report the case of a 61-year-old man with a mycotic aneurysm in the left brachial artery, that appeared during treatment with antibiotics against infective endocarditis caused by Streptococcus sanguinis. After confirming the collateral blood flow on arteriography, we resected the aneurysm and performed valvu...
