Background The LAmbre™ occluder is a novel device for percutaneous left atrial appendage closure (LAAC). The presented study aimed to report the initial experience in implantation of the novel LAmbre for LAAC in patients with nonvalvular AF. Methods We conducted a prospective, observational, cohort registry study to evaluate the feasibility of percutaneous LAAC using the LAmbre system. Results Thirty patients (15 female, mean age 77.6 ± 8.9 years) who had high risks of stroke and contraindications for oral anticoagulation were prospectively enrolled in this registry study. The mean CHA2DS2‐VaSc was 3.9 ± 1.5, and the mean HAS‐BLED score was 4.1 ± 1.0. Twenty (66.7%) patients had chicken‐wing LAA morphology. The implant success rate was 100%. The mean fluoroscopic time and procedure time were 3.5 ± 1.9 and 29.0 ± 10.1 minutes, respectively. No significant procedure‐related complications were observed during in‐hospital and acute clinical follow‐up. Conclusion In this preliminary study, the LAmbre occluder showed an excellent implant success rate, favorable implant property, and very low incidence of complications. Larger sample, randomized studies are further warranted.
