Available transvenous occluder designs and implantation techniques

Abstract

In this article, most of the present or available in the near future left atrial appendage (LAA) occlusion devices are discussed in terms of structure of the devices and principle technique for implantation. Thus, the Watchman™ device from Boston, the Amulet™ device from Abbot, the Lambre™ device from Lifetech, the Occlutech® device from Occlutech®, and the WaveCrest® device from Biosense Webster (former Coherex) are discussed. The systems differ in terms of the concept of occlusion. Several devices consist of only one part (Watchman™ and Occlutech®) that is implanted in the body, ending up in the orifice of the LAA. Others like the Amulet™ or Lambre™ device have an additional disc covering the orifice of the LAA from the left atrial side. The distal anchoring system is implanted first in the body of the LAA; thereafter, the disc is placed upon the orifice. With the WaveCrest® device, covering of the orifice is performed as the first step followed by rolling in the anchoring system to fix the device to the body of the LAA.

Atrial Filbrillation

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

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. 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.
