Infective Endocarditis in Patients with Hypertrophic Cardiomyopathy

Abstract

A literature review is presented, reflecting the incidence, etiology, hemodynamics, localization, clinical manifestations, outcomes and treatment of infective endocarditis (IE) in patients with hypertrophic cardiomyopathy (HCM). Despite the relative rarity of IE in patients with HCM, the combination of these pathologies is characterized by mutual aggravation and poor prognosis. The addition of IE increases the risk of death in patients with obstructive HCM, deteriorating circulatory disorders, increasing the likelihood of uncontrolled sepsis and embolism. Conservative treatment of IE in patients with HCM does not differ from that without HCM. Interdisciplinary interaction is needed in the management of patients with IE against the background of HCM in determining the indications for cardiac surgery and choosing the optimal method. Antibacterial prophylaxis of IE before invasive medical manipulations in patients with HCM is not recommended by the current consensus documents, however, the decision for each patient should be made individually, with a mandatory assessment of the risk of IE, the severity of hemodynamic disorders and prognosis.
