Vasoplegic syndrome after cardiopulmonary bypass for paravalvular leak of mitral bioprosthesis

Abstract

Vasoplegic syndrome (VS) is characterized by low systemic vascular resistance paired with relatively preserved cardiac output that may result in increased morbidity and mortality rate after open-heart surgery utilizing cardiopulmonary bypass. We report a case of a 61-year-old male who underwent redo open-heart surgery due to a paravalvular leak of the previous implanted mitral bioprosthesis and severe tricuspid regurgitation. The patient experienced the VS in the intensive care unit after the operation. He was resuscitated by vasopressors and recovered uneventfully.
