AI Article Synopsis

  • Watchman FLX is now approved in the US for LAAO and using ICE as a guide can simplify the procedure and lower costs compared to TEE.
  • A study of 190 patients showed successful LAAO with no significant complications, and procedural times were notably shorter with ICE.
  • The conclusion indicates that ICE-guided LAAO is a safe and effective method, offering benefits such as reduced procedural time and potentially lower radiation exposure.

Article Abstract

Introduction: Watchman FLX has been recently approved for left atrial appendage occlusion (LAAO) in the US. Intracardiac echocardiography (ICE) - which is already commonly used to guide trans-septal access - can serve as an alternative to TEE, simplifying the procedure and reducing associated costs. Herein, we report our experience with ICE-guided LAAO with Watchman FLX.

Methods And Results: This cohort study included the first 190 consecutive patients who underwent LAAO with Watchman FLX in our center. LAAO was successful in all patients without significant peri-procedural, device-related complications in either group. Compared to TEE, we observed a significant reduction in procedural times when using ICE. In addition, there was a potentially clinically relevant reduction in fluoroscopy dose, mainly secondary to fewer cine acquisition runs. At follow-up, no cases of device embolism were noted, whereas the rate of device-related thrombosis and peri-device leaks were comparable between groups.

Conclusion: ICE-guided LAAO with Watchman FLX is safe and feasible, with a significant reduction in procedural time and potential reduction in fluoroscopy dose when compared to TEE.

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: 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.

Background: Left atrial appendage occlusion (LAAO) is increasingly used as an alternative to oral anticoagulation for stroke prevention in select patients with atrial fibrillation. Data on outcomes in racial and ethnic minority individuals are limited. This analysis assessed differences in the use and outcomes of LAAO by race and ethnicity in a large national registry.

Article Synopsis
  • The study examines outcomes of percutaneous left atrial appendage occlusion (LAAO) procedures performed by either electrophysiologists (EPs) or interventional cardiologists (ICs) between 2020 and 2022, focusing on patient safety and complications.
  • Key findings indicate that EPs utilized intracardiac echocardiography more frequently and achieved lower radiation exposure; however, rates of major adverse events (MAE) and in-hospital mortality were comparable between the two groups.
  • Overall, LAAO was deemed safe with no significant differences in outcomes based on operator certification, highlighting the importance of continued use of these techniques by both specialties for broader patient access.

Introduction: Real-world studies comparing safety and efficacy of combined percutaneous left atrial appendage occlusion (LAAO) and catheter ablation (CA) to LAAO alone are limited.

Methods: Patients from a large US hospital system undergoing combined LAAO and left-atrial CA from 8/2020 to 2/2024 were retrospectively analyzed and compared to a control group undergoing LAAO alone. Controls were identified using a 1:2 propensity score match based on LAAO device type (Watchman FLX vs.
