Background: Atrial fibrillation (AF) is the most common arrhythmia in patients undergoing cardiac valve surgery. AF in patients undergoing surgery can be categorized as preoperative AF (PPAF) or postsurgical AF (PSAF).
Objective: To determine whether PSAF in patients undergoing valve surgery had an impact on mortality compared with patients in sinus rhythm or PPAF.
Methods: A total of 556 consecutive patients who underwent valve surgery were reviewed. Patients were divided into three cohorts: sinus rhythm before and after surgery (n=293); PPAF (n=139); and sinus rhythm before and AF after the surgery (PSAF) (n=124). Baseline characteristics, surgical details and outcomes were recorded.
Results: Compared with patients in sinus rhythm (mean [± SD] age 67.8±12.5 years), patients in the PPAF and PSAF groups were significantly older (73.1±9.9 ye.. Read More»
