Background The impact of new‐onset atrial fibrillation (AF) after aortic valve (AV) surgery on mid‐ and long‐term outcomes is under debate. Here, we sought to follow up heart rhythms after AV surgery, and to evaluate the mid‐term prognosis and effectiveness of treatment for patients with new‐onset AF. Methods This single‐center cohort study included 978 consecutive patients (median age, 59 years; male, 68.5%) who underwent surgical AV procedures between 2017 and 2018. All patients with postoperative new‐onset AF were treated with Class III antiarrhythmic drugs with or without electrical cardioversion (rhythm control). Status of survival, stroke, and rhythm outcomes were collected and compared between patients with and without new‐onset AF. Results New‐onset AF was detected in 256 (26.2%) patients. For them, postoperative survival was comparable with those without new‐onset AF (1‐year: 96.1% vs. 99.3%; adjusted P = .30), but rate of stroke was significantly higher (1‐year: 4.0% vs. 2.2%; adjusted P = .020). With rhythm control management, the 3‐month and 1‐year rates of paroxysmal or persistent AF between patients with and without new‐onset AF were 5.1% versus 1.3% and 7.5% versus 2.1%, respectively (both P
