P77 A “GIANT” IN THE PANDORA’S BOX OF PARACARDIAC MASS

Abstract In this case report, we describe a giant coronary aneurysm (CAAs) of the right artery occasionally found in patient that underwent Bentall procedure 18 years earlier for acute aortic dissection. A 77–year–old man, former smoker, with type II diabetes, hypertension, dyslipidaemia, and obesity, was referred to our echo lab echocardiography December 2020. His medical history included anteroseptal non–Q–wave myocardial infarction (1983), dissection treated implantation mechanical valve (2002), reparation abdominal (2003). During echocardiogram paracardiac mass incidentally found, close contact atrium diameter 60 mm A4Ch–view, appearance cystic formation (Figure A). After few days, CT angiography performed, evidence 61.6 mm–sized located proximal artery, characterised by calcified walls, eccentric thrombosis, compression B). The subsequently evaluated Cardiac Surgery Division. Conservatively management regular follow–up because high surgical risk redo lack symptoms. November 2022 performed stability size C). CAAs are defined as when vessel is greater than 20 mm. These pathological entities extremely rare, an incidence rate 0.02%, aetiologies various. most frequent comprehend atherosclerosis (about 50% cases), congenital (17%), arteritis (e.g., Kawasaki disease), connective tissue disease. Our occasional diagnosis CAA after Surgery, absence inflammatory vessels To best knowledge, It’s largest described literature cardiac surgery. Therefore, cardiologists should consider these rare approaching incidental echocardiographic finding mass, especially patients burden atherosclerotic This report underlines furthermore importance integrated approach differential mass.
