Abstract

Recent clinical trials using panoramic mapping techniques have shown success in targeting rotors and focal impulses in atrial fibrillation (AF). Ablations directed toward these organized sources improve outcomes in AF. The left atrial appendage (LAA) has been suspected as a possible extrapulmonary source of AF, and ablation within the LAA or electrical isolation of the LAA improves outcomes in certain cases. This case highlights a unique example of panoramic imaging created with a computational mapping algorithm integrated in 3-dimensional mapping, which identified rotors within the LAA. Furthermore, ablations performed near an identified rotor core within the LAA terminated AF.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.

Atrial Filbrillation

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.

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.
