Abstract

Infective endocarditis of the mitral valve that is refractory to medical therapy requires surgical debridement. However, patients who are high risk for surgery have limited options. We report 3 cases of refractory infective endocarditis involving the mitral valve that were treated with percutaneous mechanical aspiration with an embolic protection system. (Level of Difficulty: Intermediate.).
