Transcatheter left atrial appendage closure offers a new stroke prevention method for nonvalvular atrial fibrillation patients. This article details techniques and devices like WATCHMAN for successful procedural outcomes.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Nonvalvular atrial fibrillation (NVAF) increases stroke risk.
- Oral anticoagulation is the standard stroke prevention, but carries bleeding risks.
- Transcatheter left atrial appendage (LAA) closure is an emerging alternative for NVAF stroke prevention.
Purpose of the Study:
- To describe the procedural steps for transcatheter LAA closure.
- To provide tips and tricks for successful LAA closure procedures.
- To review four specific LAA closure devices: WATCHMAN, AMPLATZER Cardiac Plug, Coherex WaveCrest, and LARIAT.
Main Methods:
- Detailed description of transcatheter LAA closure techniques.
- Review of procedural steps and best practices.
- Focus on four commercially available LAA closure devices.
Main Results:
- Successful LAA closure is achievable through meticulous procedural technique.
- Understanding device-specific nuances is crucial for optimal outcomes.
- Tips and tricks enhance procedural success and minimize complications.
Conclusions:
- Transcatheter LAA closure is a viable alternative to oral anticoagulation for stroke prevention in NVAF.
- Mastery of procedural techniques and device selection is key to successful LAA closure.
- Continued development in devices and techniques is advancing LAA closure as a standard therapy.

Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
