A rare case of Mycobacterium abscessus subspecies abscessus prosthetic valve endocarditis and the clinical importance of inducible erm(41) gene testing

Disseminated Mycobacterium abscessus with endocarditis

We present an uncommon case of endocarditis caused by Mycobacterium abscessus in an immunocompetent patient following a caesarean section. We discuss her turbulent admission course leading to her diagnosis following persistent M. abscessus bacteraemia, medical and surgical management, including a splenectomy and valve resection and repair, and subsequent prolonged course of combination antimicrobials for 24 months post valve surgery. The patient is alive 9 months after completing her treatment and 36 months after her valve surgery. We emphasise the importance of a multidisciplinary team approach in the management of such a complex case.

Pulmonary valve infective endocarditis caused by Mycobacterium abscessus

Infective endocarditis caused by Mycobacterium abscessus is an uncommon event that, when it does occur, usually requires surgical valve replacement. The pulmonary valve is the least common heart valve involved in infective endocarditis. We present a rare case of isolated pulmonary valve endocarditis with Mycobacterium abscessus in a patient with recurrent sternal infections following repeated coronary artery bypass.

Fever work-up unfolds a rare diagnosis of native valve endocarditis caused by Mycobacterium abscessus

Endocarditis caused by Mycobacterium abscessus is rare and often missed without appropriate blood cultures. It does not respond to standard antitubercular treatment and is also resistant to many other antibiotics. The course of the disease may be indolent and often results in a fatal outcome. Accurate identification and sensitivity, combination therapy, and prolonged duration of antibiotics are, therefore, important for a successful outcome.

Disseminated Mycobacterium abscessus Infection Secondary to an Infected Vascular Stent: Case Report and Review of the Literature

Mycobacterium abscessus is a rapidly growing, multidrug-resistant mycobacteria, commonly associated with pulmonary, skin, and soft tissue infections. We describe a rare case of M abscessus endovascular stent infection; only 3 cases of graft infections have previously been reported.
