    Author: Shan SD, Bozso SJ, Akioyamen L, MacArthur R.
    Journal: Ann Thorac Surg; 2021 May; 111(5):e335-e337. PubMed ID: 32987021.
    Abstract:
    A 20-year-old man with severe aortic insufficiency received a mechanical aortic valve replacement. Afterward he subsequently presented with an aortic root dissection, pseudoaneurysm, and prosthetic valve endocarditis requiring surgical reinterventions twice with a positive Mycobacterium chimaera tissue culture despite prolonged antimycobacterial therapy. This is the first reported clinical case of M chimaera in Western Canada and the first with M chimaera-associated aortic dissection and pseudoaneurysm.
