Aims The aim of the present study was to evaluate the procedural feasibility, the safety and the 1-year outcome following left atrial appendage (LAA) closure using the Amplatzer cardiac plug (ACP) in Belgium. Methods and results Data were prospectively collected among 90 consecutive patients, undergoing LAA closure with an ACP in 7 Belgian centres between June 2009 and September 2012. The patients (56 males, 74 ± 8 years) were at high risk for stroke (CHA2DS2-VASc = 4.4 ± 1.8) and bleeding (HAS-BLED = 3.3 ± 1.3). Technical success was obtained in all but one patient and procedural success was 95%. Procedural major adverse events (MAE) were 3 tamponades resulting in death in one case. Minor complications were 3 insignifi cant pericardial eff usions, 2 transient myocardial ischaemia due to air embolism and 1 femoral pseudoaneurysm. At 1-y follow-up, there were 4 deaths, 2 minor strokes, 1 tamponade and 1 myocardial infarction. Overall survival was 94% and freedom from MAE was 88%. In our population, the expected annual stroke risk according to the CHA2DS2-VASc score was 5.08%, while the observed stroke rate was 2.14%/year. Conclusions The Belgian registry shows that LAA closure using the ACP device is feasible and safe. At 1-y follow-up, the observed stroke rate was 2.14%/year, less than predicted by the CHA2DS2-VASc score. Longer follow-up is needed to evaluate the long-term safety and its effi cacy in reducing stroke.

Aims Literature suggests a beneficial effect of percutaneous left atrial appendage occlusion (LAAO) to prevent thrombo-embolic events in patients with non-rheumatic atrial fibrillation (AF). We compared outcome of LAAO versus ‘suboptimal standard’ treatment in AF patients with high bleeding risk. Methods and results Patients with sufficient follow-up data (n = 125) who underwent LAAO with the Amplatzer Cardiac Plug (ACP) were selected from the Belgian ACP database. AF patients who survived intracranial haemorrhage were recruited from the Leuven Neurosurgical Registry (LNR, n = 113). After propensity score adjustment, the outcome of both groups was compared for the combined end point (death, stroke, transient ischaemic attack, systemic emboli, and major bleeding event). The LAAO group did not differ from the LNR group for mean age and gender (74 ± 7 versus 75 ± 10 years, P = 0.29; female 39% versus 48%, P = 0.18). However, the CHA2DS2-VASc and HAS-BLED scores were both higher in the LAAO group (4.8 ± 1.7 versus 3.9 ± 1.7, P = 0.0001; 3.5 ± 1.4 versus 3.2 ± 1.4, P = 0.036). After propensity score adjustment, the risk for the primary end point was significantly higher for the LNR group (HR 2.012, 95% CI 1.113-3.638). Conclusion LAAO with ACP seems to improve the combination of survival and the prevention of thrombo-embolic and major bleeding events in patients with atrial fibrillation and increased bleeding risk. © 2016, Acta Cardiologica.
