Despite initial medical management, she developed refractory New York Heart Association functional class III heart failure, uncontrolled atrial fibrillation, and further enlargement of her pseudoaneurysm to 5.5 \u00d7 10.6 \u00d7 9.2 cm. She underwent urgent aneurysmectomy. Left ventricular pseudoaneurysms are rare and most commonly occur following an acute myocardial infarction when a ventricular free-wall rupture is contained by pericardium or thrombi. Historically, left ventricular angiography displaying a lack of an overlying coronary artery was the gold standard for diagnosis. Now, noninvasive imaging such as computed tomography, magnetic resonance imaging, and echocardiogram with ultrasound-enhancing agent, are reliable diagnostic tools. They can distinguish a pseudoaneurysm from a true left ventricular aneurysm using characteristic findings such as a narrow aneurysm neck, bidirectional doppler flow between the pseudoaneurysm and the left ventricle, and abrupt changes in the cardiac wall structures. Progressive dilation, wall thinning, and dyskinesis can result in refractory heart failure, arrhythmias, and thrombi formation from venous stasis. Pseudoaneurysms have a 30% to 45% risk of rupture and can be treated with left ventricular aneurysmectomy.<\/jats:p>","DOI":"10.14503\/thij-22-7922","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T14:25:20Z","timestamp":1680099920000},"source":"Crossref","is-referenced-by-count":2,"title":["Large Left Ventricular Pseudoaneurysm Presenting as an Embolic Stroke After a \u201cSilent\u201d Myocardial Infarction"],"prefix":"10.14503","volume":"50","author":[{"given":"Cameron","family":"Incognito","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Medicine Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua","family":"Parker","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Heart and Vascular Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Arustamyan","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Medicine Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milad","family":"Matta","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Medicine Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristine","family":"Posadas","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Medicine Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ran","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Heart and Vascular Institute, Cleveland Clinic, Cleveland, Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5628","reference":[{"issue":"5","key":"i1526-6702-50-2-e227922-b1","series-title":"Chest.","doi-asserted-by":"publisher","first-page":"1403","DOI":"10.1378\/chest.111.5.1403","article-title":"Distinguishing left ventricular aneurysm from pseudoaneurysm.
