Percutaneous left atrial appendage closure using a modified single-operator-technician approach under deep sedation: A single-center experience.

Department of Electrophysiology, North Mississippi Medical Center, Tupelo, Mississippi.
Background: Historically, percutaneous transcatheter left atrial appendage closure (LAAC) has been performed under general anesthesia (GA) with transesophageal echocardiographic images obtained by a noninvasive cardiologist and usually requires an overnight hospital stay. Alternatively, we present our single-center experience performing LAACs under deep sedation (DS), employing an echocardiographic technician instead of a noninvasive cardiologist, and expediting same-day discharge. Mid- to long-term outcomes were also evaluated with follow-up imaging at a 45-day visit.

Background: Different left atrial appendage closure (LAAC) devices have been introduced into the clinical setting. A new dual-seal mechanism LACbes® occluder with isogenous barbs for LAAC has been designed to facilitate easier delivery and improve safety. The purpose of this study is to compare the clinical outcomes of the WATCHMAN with those of the LACbes® device for LAAC.

Article Synopsis
- Left atrial appendage closure (LAAC) is an alternative for patients with nonvalvular atrial fibrillation (NVAF) to avoid oral anticoagulants, but issues like incomplete device endothelialization (IDE) can lead to complications.
- A study compared the endothelialization rates after implantation of two devices: the Watchman plug and the LACBES occluder, in 201 patients, using cardiac computed tomography angiography (CCTA).
- Results showed that the LACBES occluder had a higher IDE rate at both 3 and 6 months compared to the Watchman device, indicating that it takes longer for the LACBES to achieve complete endothelialization after LAAC.
Transfabric Leaks After Percutaneous Left Atrial Appendage Occlusion Procedures with the WATCHMAN FLX Device.

Background: Cardiac computed tomography imaging with contrast is being used increasingly to image left atrial appendage occlusion (LAAO) devices. Contrast flow across a device, also known as a transfabric leak (TFL), may indicate a lack of complete LAAO-device endothelialization. The data on the rate, predictors, and clinical events associated with TFL are limited.
