Severe infective endocarditis in a patient with hypertrophic obstructive cardiomyopathy: 12 years after combined surgery. A case report

Brief description. A 40-year-old male patient with obstructive hypertrophic cardiomyopathy (HCM) developed episodes of fever up to 39,0° C after carotid endarterectomy. Mitral and aortic valve Enterococcus faecium -induced infective endocarditis was diagnosed. Antibacterial therapy was continued for 3 months. As a result, the infectious and inflammatory process was suppressed, but severe mitral and aortic valve insufficiency required surgical treatment. During the operation, the patient underwent replacement of both affected valves, as well as extended myectomy and cardioverter-defibrillator implantation to prevent sudden cardiac death. Twelve years after surgical treatment of infective endocarditis and HCM, the patient's condition is stable. Discussion. Patients with HCM have an increased risk of infective endocarditis, but with timely diagnosis and active treatment of endocarditis, a good long-term prognosis is possible. In this case, the combined surgery played an extremely important role.
