Left atrial appendage closure : Current data and future developments

Herz. 2021 Aug 31. doi: 10.1007/s00059-021-05065-8. Online ahead of print.ABSTRACTCatheter-based left atrial appendage closure (LAAC) is currently a potential treatment option for stroke prevention in patients with atrial fibrillation and high risk for stroke/embolism as well as high bleeding risk. Due to improvements in LAAC devices, advances in implantation techniques and growing experience of the interventional teams, the safety profile of LAAC has significantly improved in recent years. These developments have led to a currently comprehensive exploration of novel indications for LAAC, such as patients with atrial fibrillation and a low risk of hemorrhage, patients with atrial fibrillation after pulmonary vein ablation or patients after electrical isolation of the left atrial appendage. The treatment principle of closure of the left atrial appendage is supported by new data, which show the effectiveness of surgical closure of the left atrial appendage with respect to a reduction of the risk of stroke, at least partly in conjunction with oral anticoagulation during cardiological surgical interventions. Currently, the application in the clinical practice is reflected by a high degree of active studies. These randomized studies are testing the use of LAAC in new fields of application and together with the new developments in implantation techniques should define the optimal future use of the methods for the clinical practice. The current potential indications for the LAAC pro...
