CORONARY ARTERY BYPASS

It is now widely accepted that approximately 50 per cent of patients
undergoing mitral valve repair and/or replacement surgery and up to 20
per cent of patients undergoing coronary artery bypass surgery (CABG)
also have AF. Surgeons believe that it is appropriate to treat the
patients' atrial fibrillation as a secondary outcome, while the patient
is being primarily treated for mitral valve disease or coronary vessel
obstruction.
