Does pre-operative atrial fibrillation worsen survival and cardiac event-free rates in patients undergoing mitral valve repair for degenerative mitral regurgitation?
Pre-operative atrial fibrillation is a strong independent predictor of reduced survival and increased cardiac morbidity in patients undergoing mitral valve repair for degenerative mitral regurgitation.
Eguchi et al. (2005) studied this question.
