RESUMEN
OBJECTIVES: To discuss the dilemma of adequate decision making in patients with intravenous drug abuse and recurrent valve prosthesis infections or in patients with positive HIV or hepatitis C status. Ethical, social, and economic considerations, not only in terms of technical feasibility but also in terms of unpromising results and aspects of resources, are discussed. Thoughts are presented about the legitimation of cardiac surgery centers refusing to perform surgery in high-risk patients with HIV or hepatitis C infections. METHODS: Presentation of six cases for discussion. Three patients were addicted to intravenous drugs and had recurrent prosthetic valve endocarditis, and the other three patients had either paravalvular leakage of a mitral valve prosthesis or acute aortic dissection or coronary artery disease. Five of these patients suffered from HIV/AIDS and infective hepatitis C. Four of these patients were refused by other centers due to high risk or a lack of capacity. RESULTS: All six patients were operated during 2013. Mortality was 17%. CONCLUSION: Decision making in noncompliant drug addicts with recurrent prosthesis infection and in HIV-positive patients leads beyond surgical challenges to ethical and economic considerations.
