Catheters, Cardiac, Ablation

Definition : Cardiac catheters that eliminate (ablate) regions of endocardial tissue that give rise to or support cardiac arrhythmia (arrhythmogenic myocardium). Multielectrode catheters for radio-frequency ablation at several hundred kHz frequency are mostly used, but several different catheters have been used or tested for cardiac ablation, including multielectrode catheters for DC ablation that typically apply 200 to 400 J discharges from a defibrillator; microwave ablation catheters that include helical antennas, thermocouples, and special electrodes; and double-lumen infusion catheters for sequential administration of mapping and ablation injectants into endocardial target sites. These catheters may be used for interruption of atrioventricular (AV) conduction pathways, treatment of AV nodal reentrant tachycardia, creation of complete AV block in some cases of atrial arrhythmias, treatment of atrial flutter/fibrillation, and treatment of ectopic atrial tachycardia.

CardioFocus Inc

Company Type: Parent

Atrial fibrillation is the rapid and uncontrolled beating of the atria, the upper chambers of the heart, and is the most common cardiac arrhythmia. It can result from congestive heart failure, myocardial infarction, valvular disease, hypertension, infection, or, in 20 to 35% of cases, without any evidence of other cause. Patients with AFib experience palpitations, chest discomfort, weakness, fainting and breathlessness. Their quality of life can be so severely reduced that in one study the average quality of life was equivalent to that of patients crippled from rheumatoid arthritis and below that for patients with congestive heart failure or recent myocardial infarction.
