Abstract We present a case of Mycobacterium chimaera infection presenting with aortic dissection and pseudoaneuysm in a 22-year-old man with a past history of aortic valve replacement. Clinicians should consider M. chimaera infection in those presenting with aortic dissection as a late complication of cardiovascular surgery.

AbstractLeft ventricular outflow tract pseudoaneurysm is an uncommon complication following aortic valve replacement (AVR), occurring most frequently secondary to endocarditis. We present a case of a 47-year-old female with a history of intravenous drug abuse and a past surgical history of two AVRs (2001 and 2009 with aortic root replacement for endocarditis) who presented with symptoms of lower extremity weakness. Subsequent radiologic imaging revealed the presence of a left ventricular outflow tract pseudoaneurysm, which was surgically managed with a homologous conduit.

A 77-year-old man with a history of coronary artery bypass grafting and surgical aortic valve replacement for severe aortic stenosis 2 years prior presented with exertional chest pain and shortness of breath. The patient underwent a thorough initial evaluation including a transthoracic echocardiogram and coronary angiogram without significant findings. One month later the patient presented with worsened symptoms and a repeat echocardiogram showed an increased mean aortic valve gradient of 87 mm Hg. The patient had to undergo reoperation for a surgical aortic valve replacement and was found to have an aortic bioprosthetic valve thrombus. This case suggests a mismatch between the aortic prosthesis and the patient’s aortic root size.
