Key result
Postsurgical atrial fibrillation was associated with a significantly higher risk of long-term all-cause mortality (HR 1.64) compared to sinus rhythm in patients undergoing cardiac valve surgery.

Does preoperative or postsurgical atrial fibrillation impact long-term survival in patients undergoing cardiac valve surgery compared to sinus rhythm?
Both preoperative and postsurgical atrial fibrillation are associated with significantly higher long-term all-cause mortality and longer hospital stays compared to sinus rhythm in patients undergoing cardiac valve surgery.
Postsurgical AF after valve surgery warrants closer monitoring; leaves open whether rhythm interventions improve survival.
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.

Shariff et al. (2015) conducted a cohort in Cardiac valve surgery (n=556). Postsurgical atrial fibrillation (PSAF) vs. Sinus rhythm was evaluated on All-cause mortality (HR 1.64, 95% CI 1.07 to 2.53, p=0.02). Postsurgical atrial fibrillation was associated with a significantly higher risk of long-term all-cause mortality (HR 1.64) compared to sinus rhythm in patients undergoing cardiac valve surgery.
