Left Ventricular Pseudoaneurysm and Rupture After Limited Myocardial Infarction
Journal of the American Society of Echocardiography, 2005
A 50-year-old man had a large lateral left ventricular wall pseudoaneurysm with rupture after a limited myocardial infarction. This was diagnosed by the combination of flow in and out of the aneurysm and pulsatile flow in the pericardial cavity using color flow and continuous wave Doppler ultrasound. This report describes the case management, the use of echocardiography in this setting, and the implications of pseudoaneurysm formation. (J Am Soc Echocardiogr 2005;18:980.e1-4.)
Left ventricular pseudoaneurysm after myocardial infarction
Heart and Vessels, 2003
In this report, a case of a left ventricular (LV) pseudoaneurysm due to a previous myocardial infarction, which was repaired successfully, is described. A 62-year-old man, with a history of acute anterior wall myocardial infarction 6 months previously, was admitted with the complaints of acute dyspnea and palpitation. Echocardiography revealed an LV aneurysm, and ventriculography showed ventricular dysfunction and an LV pseudoaneurysm. Coronary angiography showed total occlusion of the proximal segment of the left anterior descending artery with a very thin lumen and insufficient retrograde filling. Under cardiopulmonary bypass and beating heart, the pseudoaneurysm was resected and the defect on the ventricular free wall was closed by the remodeling ventriculoplasty method of Dor. Histopathologic examination of the resected material confirmed the diagnosis of pseudoaneurysm. The postoperative course of our patient was uneventful. He was discharged on the ninth postoperative day.
Surgical treatment of post-infarction left ventricular pseudoaneurysm: a two-decade experience
Texas Heart Institute journal / from the Texas Heart Institute of St. Luke's Episcopal Hospital, Texas Children's Hospital, 2007
Herein, we present a retrospective analysis of our experience with acquired pseudoaneurysms of the left ventricle over a 20-year period.From February 1985 through September 2004, 14 patients underwent operation for left ventricular pseudoaneurysm in our clinic. All pseudoaneurysms (12 chronic, 2 acute) were caused by myocardial infarction. The mean interval between myocardial infarction and diagnosis of pseudoaneurysm was 7 months (range, 1-11 mo). The pseudoaneurysm was located in the inferior or posterolateral wall in 11 of 14 patients (78.6%). In all patients, the pseudoaneurysm was resected and the ventricular wall defect was closed with direct suture (6 patients) or a patch (8 patients). Most patients had 3-vessel coronary artery disease. Coronary artery bypass grafting was performed in all patients. Five patients died (postoperative mortality rate, 35.7%) after repair of a pseudoaneurysm (post-infarction, 2 patients; chronic, 3 patients). Two patients died during follow-up (me...

Introduction: Pseudoaneurysm may occur as a rare complication of myocardial infarction (MI) when a hemorrhagic process is covered by adherence of the visceral or parietal pericardium or of both, preventing the formation of cardiac tamponade. Pseudoaneurysm is prone to rupture because they are not easy to diagnose. Case presentation: Here, we report three cases of left ventricular pseudo-aneurysm (LVP) that all were related to MI. Two patients were managed conservatively, one of them was lost to follow-up, and the other one expired one month later. One patient underwent surgery, but he expired during post-operation period. Conclusions: High mortality rate of LVP emphasizes the importance of looking for it in cardiac evaluation of patients with history of MI. Due to available non-invasive modalities, the ability to differentiate LVP from other cardiac pathologies is improving. Still, the most recommended management of LVP is early surgery.
Cardiac Surgery and Follow-up Diagnosis of the Left Ventricular Pseudoaneurysm Patient
Left ventricular pseudoaneurysms (LVP) are false aneurysms caused by the rupture of left ventricular wall as a complication of myocardial infarction, cardiac surgery, congenital heart disease, and, more rarely endocarditis. It is a rare condition that initiates 3-14 days are myocardial infarction affecting 0.5% of the patients. The known risk factors to develop LVP are age, history of hypertension, deficiency of collateral circulation after myocardial infarction, and female gender. The current case report describes LVP in a 58-year old male patient with frontal acute myocardial infarction history. The patient was diagnosed using ECG, CINE-MRI, DE-IR analysis, and thorax-CT followed by urgent cardiac surgery. The diagnosis was an apical pseudoaneurysm caused by previous myocardial necrosis. The Immunohistochemistry suggested cardiac fibrosis. The patient was discharged asymptomatic for angina pectoris, dyspnea and palpitations, and prescribed warfarin against clotting, β-blocker/vasodilator, furosemide diuretic, angiotensin receptor blocker, and proton pump inhibitor medication. After six months of follow-up, the patient demonstrated the absence of preoperative symptoms.
Surgical Treatment of Postinfarction Left Ventricular Pseudoaneurysm
The Annals of Thoracic Surgery, 2007
Background. Left ventricular pseudoaneurysm from myocardial infarction is rare and is associated with a high risk of rapid enlargement and rupture. The purposes of this study were to describe its clinical presentation, assess the accuracy of diagnostic imaging modalities, and determine operative and late surgical results. Methods. From January 1986 through December 2001, 30 patients aged 50 to 85 years (mean, 68; 70% male) underwent left ventricular pseudoaneurysm repair. Two surgical approaches were used: primary repair (n ؍ 5, 17%) and patch closure (n ؍ 25, 83%). Twenty-one patients (70%) had concomitant procedures, including coronary revascularization (n ؍ 17, 57%) and mitral valve surgery (n ؍ 9, 30%); 8 patients (29%) underwent emergent surgery. Clinical presentation, preoperative imaging data, and surgical outcomes were abstracted from medical records or obtained by patient follow-up. Results. The most common clinical presentations were heart failure (n ؍ 22, 73%) and angina (n ؍ 11, 41%). Pseudoaneurysm was rarely suspected at clinical presentation. Contrast ventriculography was diagnostic in 54% of patients in whom it was performed, as opposed to 97% for two-dimensional echocardiography (p ؍ 0.2). Postoperative intra-aortic balloon pump was required in 7 patients (23%). Hospital mortality was 20%, and late survival was 73%, 59%, and 45% at 1, 5, and 8 years, respectively. Conclusions. Left ventricular pseudoaneurysm should be suspected in postinfarction patients with unexplained heart failure. Echocardiography is usually diagnostic and is superior to ventriculography. The surgical mortality rate is elevated in this complex patient population. Longterm survival is also poor, mainly because of underlying ischemic cardiomyopathy.
Pseudoaneurysm Development after Free Wall Rupture Post Myocardial Infarction
Journal of Cardiovascular Development and Disease, 2020
Background: According to the World Health Organization, cardiovascular disease is the number one cause of death globally, claiming millions of lives each year with an increasing prevalence. Myocardial infarction (MI) makes up a large sum of these deaths each year. While MI in itself is lethal, there are several complications that can increase the morbidity and mortality of an MI, such as left ventricular wall rupture and aneurysms. Case Presentation: We present a case of an elderly male with an extensive cardiac history who presented with a non-ST segment myocardial infarction (NSTEMI) managed with percutaneous coronary intervention. Hours after, he became hemodynamically unable and was found to have a pseudoaneurysm of the left ventricle. Despite aggressive efforts, his pseudoaneurysm ruptured and he ultimately succumbed to his condition. Conclusions: Left ventricular pseudoaneurysm is usually seen after myocardial infarctions with a rupture rate of up to 45% leading to a mortality...
Surgical Treatment of Postinfarction Left Ventricular Pseudoaneurysms
The Heart Surgery Forum, 2006
Left ventricular pseudoaneurysm is a rare but serious complication of acute myocardial infarction. It is under debate whether surgical intervention is mandatory in asymptomatic patients. The aim of this report was to present our experience based on surgical treatment and midterm outcomes of patients with postinfarction left ventricular pseudoaneurysm.
