The annual incidence of stroke in patients with nonrheumatic atrial fibrillation averages 5% per year and increases with age, left ventricular dysfunction, hypertension, diabetes or prior stroke. Since in nonrheumatic atrial fibrillation 91% of left atrial thrombi are located in the left atrial appendage, in patients ineligible for oral anticoagulation it was suggested the percutaneous closure of left atrial appendage as a therapeutic option to reduce embolic risk. In this article we report our initial experience with this procedure, which was uneventful and efficacious at short-term follow-up. In conclusion, the interventional approach in patients with atrial fibrillation ineligible for oral anticoagulation seems feasible and promising, and deserves further investigation.

Clinical outcomes of atrial fibrillation screening: a meta-analysis of randomized controlled trials.
Ann Med
December 2025
Heart Centre, Turku University Hospital, Turku, Finland.
Background: Several randomized controlled trials (RCTs) have investigated the benefits of atrial fibrillation (AF) screening. However, since none have shown a significant reduction in stroke rates, the impact of screening on clinical outcomes remains uncertain.
Materials And Methods: We conducted a systematic review and meta-analysis of RCTs reporting clinical outcomes of systematic AF screening in participants without known AF.

Research evidence has demonstrated a significant association between hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF), but the causality and pattern of this link remain unexplored. Therefore, this study investigated the causal relationship between HCM and AF using a two-sample and bidirectional Mendelian randomization (MR) approach. Additionally, this assessed the role of cardiovascular proteins (CPs) associated with cardiovascular diseases between HCM and AF by applying a two-step MR analysis.

: New-onset postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery, occurring approximately in one-third of the patients. This study considered all-comer patients who underwent cardiac surgery to build a predictive model for POAF. : A total of 3467 (Center 1) consecutive patients were used as a derivation cohort to build the model.

: The prognosis of acute decompensated heart failure (ADHF) and heart failure (HF) with atrial fibrillation (AF) has been dismal. This study was performed to investigate the clinical outcomes of catheter ablation (CA) performed in patients with concurrent ADHF and AF. : We retrospectively analyzed ADHF patients with AF who were admitted to our institution from 2007 to 2017.

Frailty is increasingly being recognized as a risk factor for adverse outcomes in older surgical patients undergoing surgery. We investigated the association between frailty and intraoperative complications using multiple frailty assessment tools in older patients undergoing elective intermediate- to high-risk non-cardiac surgery. This retrospective cohort study included 637 older patients scheduled for elective non-cardiac surgery.
