Abstract

Purpose: Patients with atrial fibrillation are at an increased risk of having a cardio embolic stroke. Stroke is a leading cause of death and disability worldwide. Current guidelines recommend an antithrombotic regimen to prevent thromboembolism in medium and high risk patients with AF. However, a substantial number of patients are not eligible for this therapy. The exclusion of the left atrial appendage (LAA) from circulation seems to be an alternative strategy for stroke prevention in AF. This review focuses on the different strategies for LAA exclusion with special focus on the WATCHMAN Device. Two devices are currently in use for percutaneous transcatheter occlusion of the LAA: the WATCHMAN® - device and the AMPLATZER® -septal occluder. For both devices safety and feasibility data are available. Additionally about 200 patients received a PLAATO® -device- which is currently no more available due to economic reasons. Patients treated with the PLAATO device were at high risk for thromboembolic stroke and had contraindications for oral anticoagulation therapy. The Watchman® -device was implanted in 800 patients that were eligible for long-term anticoagulation therapy with a moderate risk for thromboembolic stroke due to non-val...Continue Reading

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
