Long-term Thromboembolic Risk in Patients With Postoperative Atrial Fibrillation After Left-Sided Heart Valve Surgery.

ABSTRACT:

Importance

New-onset postoperative atrial fibrillation (POAF) is a common complication of cardiac surgery. However, data on the long-term risk of thromboembolism in patients who develop POAF after heart valve surgery are conflicting. In addition, data on stroke prophylaxis in this setting are lacking.

Objective

To assess the long-term risk of thromboembolism in patients developing new-onset POAF after isolated left-sided heart valve surgery relative to patients with nonsurgical, nonvalvular atrial fibrillation (NVAF).

Design, setting, and participants

This observational cohort study was conducted from January 1, 2000, through December 31, 2015, using Danish nationwide registries and the Eastern Danish Heart Surgery Database. Patients who developed POAF after isolated
