CALDERON, Jaime et al. Mitral, aortic or mitral-aortic valvular replacement in patients with low ejection fraction. Rev. Col. Cardiol. [online]. 2006, vol.13, n.2, pp.110-112. ISSN 0120-5633.

The decision to submit patients with moderate to severe ventricular dysfunction to valvular replacements is subject to controversy because complications and the adverse outcomes in short and long-term. The aim of this study was to evaluate the outcomes in mitral or aortic valve replacements or combined aortic and mitral valve replacements in patients with preoperative low left ventricular ejection fraction. Good symptomatic relief and acceptable overall survival can be obtained in patients with systolic dysfunction and valvular disease. Preoperative NYHA class IV increases early and late mortality. A marked ejection fraction reduction should not be considered a contraindication for valvular replacement.
