Abstract
In this report we present a patient who was initially diagnosed as suffering from mitral valve endocarditis. The proper use of diagnostic modalities revealed a pseudo aneurysm of the left ventricle which was mimicking mitral valve vegetations. This allowed better planning of the subsequent operation. The optimal preoperative diagnostic studies are discussed along with the proper surgical treatment.
Highlights
Left ventricular pseudoaneurysm is a rare condition associated with a high risk of rapid enlargement and rupture
Left ventricular pseudo aneurysm (LVPA) is a rare condition and forms when cardiac rapture is contained by pericardial adhesions or fiber tissue
The clinical presentation may vary depending upon congestive heart failure, mitral regurgitation, ventricular tachy-arrhythmia, systemic thrombo-embolism and cardiac rupture [1,2]
Summary
Left ventricular pseudoaneurysm is a rare condition associated with a high risk of rapid enlargement and rupture. They are rarely suspected at clinical presentation and their symptoms are non specific. In this case report, a large pseudo aneurysm of the left ventricle (LV) was initially mistaken for mitral valve vegetations. A subsequent coronary angiogram revealed a 90% left anterior descending (LAD) stenosis and a 100% right coronary artery (RCA) occlusion. Both were addressed with drug eluted stents and the patient was discharged two days later. He was discharged on an ambulatory setting on the 24th postoperative day and remains well in one year follow-up
