A Review of the LARIAT Suture Delivery Device for Left Atrial Appendage Closure

The prevalence of atrial fibrillation (AF) is 1-2 % in the general population, and the risk of embolic stroke in AF patients is 4-5 times higher than that in the general population. AF-related strokes are often severe, and the rate of permanent disability is much higher among individuals who have AF-related strokes than in those who have strokes unrelated to AF. In patients with AF, more than 9...

Percutaneous Left Atrial Appendage Suture Ligation Using the LARIAT Device in Patients With Atrial Fibrillation

Methods Eighty-nine patients with atrial fibrillation were enrolled to undergo percutaneous ligation of the LAA with the LARIAT device. The catheter-based LARIAT device consists of a snare with a pre-tied suture that is guided epicardially over the LAA. LAA closure was confirmed with transesophageal echocardiography (TEE) and contrast fluoroscopy immediately, then with TEE at 1 day, 30 days, 90...

Left Atrial Appendage Tachycardia Termination With A LARIAT Suture Ligation.

Left atrial appendage (LAA) is a known trigger for left atrial tachycardia (AT). The use of LARIAT epicardial suture for termination of AT arising from LAA is not yet reported. A 66-year-old female had a history of hypertension, diabetes, sick sinus syndrome, labile INR, and symptomatic persistent AF. She underwent radiofrequency ablation after failed cardioversion and multiple antiarrhythmics....

The role of multimodality imaging in percutaneous left atrial appendage suture ligation with the LARIAT device.

Atrial fibrillation (AF), the most common cardiac arrhythmia, is a significant cause of embolic stroke. Although systemic anticoagulation is the primary strategy for preventing the thromboembolic complications of AF, anticoagulants carry major bleeding risks, and many patients have contraindications to their use. Because thromboembolism typically arises from a clot in the left atrial appendage ...

Left Atrial Appendage Closure – The WATCHMAN Device

Atrial fibrillation (AF) is one of the most common arrhythmias seen in clinical cardiology practice. Patients with non-valvular AF have an approximately 5-fold increase in the risk of stroke, with an exponential increase with advancing age. Cardioembolic strokes carry a high mortality risk. Although the potential of warfarin to reduce systemic embolization in AF patients is well established, it...
