Differences In Tissue Injury and Ablation Outcomes In Atrial Fibrillation Patients - Manual versus Robotic Catheters

Journal of Atrial Fibrillation

Abstract

Robots have gained their place in almost all areas of our daily life. Robotic systems have been introduced for ablation therapies associated with the hope of automation of procedures, increase in precision of lesion placement, improved energy transmission to the tissue and reduction in radiation exposure of the patients and the interventionalist. Finally, they may be associated with higher comfort for the operator by transferring his work into the control room and thereby supersede wearing sterile and radiation protective clothing. Systems providing a remote mechanical replacement of the operators´ hands have been introduced as well as systems guiding the catheter tip by external magnets. Guiding of the catheter tip has major impact on contact to the tissue and thereby modifies energy transmission. This may be advantageous in terms of higher catheter stability and modification of contact towards a more constant than intermittent type of contact. However, increasing contact bears the risk of mechanical perforation and excessive energy delivery. Many clinical studies have been conducted evaluating novel remotely guiding techniques in atrial fibrillation ablation procedures. Although only a few of them are prospectively randomized...Continue Reading

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.

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.
