Insights
Left atrial appendage (LAA) closure using the LAmbre device effectively prevents stroke in patients with nonvalvular atrial fibrillation (NVAF). This minimally invasive procedure demonstrated a high success rate and favorable safety profile over 12 months.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- The left atrial appendage (LAA) is a primary source of thrombi in nonvalvular atrial fibrillation (NVAF) patients.
- Over 90% of blood clots in NVAF originate from the LAA.
Purpose of the Study:
- To evaluate the clinical outcomes of LAA closure using the LAmbre device.
- To assess the efficacy and safety of LAmbre device for stroke prevention in NVAF patients.
Main Methods:
- A prospective, multicenter study.
- Involved 153 NVAF patients with a CHADS2 score ≥1.
- Utilized the LAmbre closure system for LAA occlusion.
Main Results:
- Successful LAA occlusion achieved in 152 out of 153 patients.
- Serious complications reported in 5 patients.
- During 12-month follow-up: 2 ischemic strokes, 1 incomplete sealing, 0 device embolizations.
Conclusions:
- LAA closure with the LAmbre device shows promising results for stroke prevention in NVAF.
- The LAmbre system is a viable option for reducing stroke risk in this patient population.
Objectives:
The authors sought to assess the clinical outcomes of left atrial appendage (LAA) closure with the LAmbre closure system in patients with nonvalvular atrial fibrillation (NVAF).
Background:
Over 90% of thrombi are located in the LAA in NVAF patients.
Methods:
A prospective, multicenter study was conducted in 153 NVAF patients with CHADS2 score ≥1.
Results:
The LAA was successfully occluded in 152 patients. Serious complications occurred in 5 patients. During the 12-month follow-up, ischemic stroke occurred in 2 patients, 1 patient had incomplete LAA sealing, and there was no device embolization.
Conclusions:
LAA closure with the LAmbre device shows encouraging results for stroke prevention.
