Abstract
A 72-year-old woman with no history of coronary artery disease presented with an acute left middle cerebral artery stroke and was found to have a large left ventricular pseudoaneurysm measuring 8.7 × 7.6 cm and 2 large left ventricular thrombi, the source of her systemic embolization. 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 × 10.6 × 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.
期刊介绍:
For more than 45 years, the Texas Heart Institute Journal has been published by the Texas Heart Institute as part of its medical education program. Our bimonthly peer-reviewed journal enjoys a global audience of physicians, scientists, and healthcare professionals who are contributing to the prevention, diagnosis, and treatment of cardiovascular disease.
The Journal was printed under the name of Cardiovascular Diseases from 1974 through 1981 (ISSN 0093-3546). The name was changed to Texas Heart Institute Journal in 1982 and was printed through 2013 (ISSN 0730-2347). In 2014, the Journal moved to online-only publication. It is indexed by Index Medicus/MEDLINE and by other indexing and abstracting services worldwide. Our full archive is available at PubMed Central.
