Postoperative atrial fibrillation (POAF) is a common complication that occurs in 30-50% of patients after cardiac surgery and increases morbidity and mortality and hospital length of stay. During the perioperative period, the discontinuation of beta-blocker treatment is known to be a risk factor for developing POAF in patient undergoing cardiac surgery. Early beta-blocker reintroduction is associated with lower incidence of POAF. Unfortunately, side effects of currently available beta-blockers (including esmolol), such as low blood pressure and excessive bradycardia and/or their extended duration of action, limit their use in the post-operative period especially for prevention.
Landiolol, an ultra-short acting injectable beta-blocker, offers the advantage of significantly limiting low blood pressure events while increasing therapeutic efficacy in the treatment of POAF in cardiac and non-cardiac surgery. Landiolol, when used at low dose in the postoperative period, has been showed to reduce the incidence of POAF with no increased incidence of side effect as compared to standard of care. The limitation is that these promising data come from single center studies with limited samples and conducted exclusively in Japanese population. If landiolol is approved for use in the treatment of atrial fibrillation in non-Asian patients, there are no data on the prevention of POAF in cardiac surgery.
The objective of this multicenter, double-blind, randomized, placebo- controlled phase III trial is to confirm that landiolol postoperative infusion is associated with lower incidence of POAF without excess of adverse events as compared to standard of care in a non-Asian population after cardiac surgery with sternotomy.

- POAF occurrence in Intensive Care Unit (ICU) [ Time Frame: 7 days ]POAF event occurring from arrival to departure of the ICU assessed by continuous monitoring of heart rate (HR). POAF is defined as the occurrence of atrial fibrillation de novo, lasting more than 5 minutes (on the systematic reading of telemetry) and/or requiring specific medical treatment and/or cardioversion.
- Duration of POAF episode [ Time Frame: 30 days ]Duration (in hours) of POAF episode categorized into five groups: POAF < 6h, POAF sustained ≥ 6h, POAF sustained ≥ 12h, POAF sustained ≥ 24h and POAF sustained ≥ 48h.
- Day-30 POAF free days [ Time Frame: 30 days ]
- Need for cardioversion for POAF treatment [ Time Frame: 30 days ]
- Need for medical treatment for POAF treatment [ Time Frame: 30 days ]
- Delay between ICU admission and the first event of POAF [ Time Frame: 30 days ]
- Delay between the first event and the recidive of POAF [ Time Frame: 30 days ]
- Delay for discharge because of POAF event [ Time Frame: 30 days ]
- All-cause mortality [ Time Frame: 30 days ]
- In-ICU death [ Time Frame: 30 days ]
- In-hospital death [ Time Frame: 30 days ]
- Day-30 hospital free days [ Time Frame: 30 days ]Length of hospital stay
- Day-30 ICU free days [ Time Frame: 30 days ]Length of ICU stay

- Occurrence of major cardiovascular events [ Time Frame: 30 days ]Cardiogenic shock, stroke or transient ischemic attack, seizure, cardiac arrest, myocardial infarction, Reoperation for bleeding, All-cause bleeding
- Occurrence of drug adverse events [ Time Frame: 7 days ]Bradycardia: HR < 50 bpm requiring heart pacing, Atrio-ventricular block requiring pacing, Severe hypotension: MAP < 50 mmHg requiring discontinuation of the protocol and specific treatment, Major ventricular arrhythmia requiring cardioversion.
