Multicenter Study
Multicenter study on acute and long-term safety and efficacy of percutaneous left atrial appendage closure using an epicardial suture snaring device.
Pericardial suture ligation of the left atrial appendage (LAA) may be an alternative to endoluminal devices for stroke prevention in patients with atrial fibrillation, but multicenter safety and efficacy data in high-risk patients with contraindications to oral anticoagulation are lacking. ⋯ This multicenter experience revealed that pericardial suture ligation with the LARIAT system is technically feasible and acutely efficacious. However, additional improvements are required to minimize the rate of pericardial complications. A randomized study is warranted to accurately define the long-term efficacy and safety profile of percutaneous epicardial suture ligation.
