Percutaneous left atrial appendage closure (LAAC) is effective for stroke prevention in patients with atrial fibrillation and a HAS-BLED score of 3 or higher, using the Occlutech device (OD).
In a study of 30 patients from 2012 to 2016, LAAC was successfully implanted in 93% of cases, with only minor complications like small leaks and one case of thrombus formation.
The results indicated high procedural success and safety, as no patients experienced significant neurological issues or strokes during the follow-up period.
