CATHETER ABLATION Meaning and
Definition
-
Catheter ablation refers to a medical procedure used to treat certain heart conditions by using a catheter to target and destroy abnormal tissue causing the issue. It is a minimally invasive procedure that aims to restore the normal electrical conduction of the heart and alleviate symptoms such as irregular heartbeats or arrhythmias.
During catheter ablation, a thin, flexible tube called a catheter is inserted into a blood vessel, typically in the groin area, and carefully threaded up to the heart. The catheter is equipped with special electrodes or radiofrequency energy devices that emit controlled energy to create small scars or lesions on specific areas of the heart tissue. These targeted lesions disrupt the abnormal electrical pathways that cause the irregular heartbeat, restoring the regular electrical rhythm. The procedure is commonly guided using real-time imaging techniques such as fluoroscopy or three-dimensional mapping systems.
Catheter ablation is most commonly used to treat conditions like supraventricular tachycardia, atrial fibrillation, atrial flutter, and ventricular tachycardia. It is often recommended when medication alone fails to adequately control or manage the heart rhythm disturbances. By permanently eliminating or disrupting the abnormal electrical pathways, catheter ablation can significantly reduce or eliminate symptoms, improve the quality of life, and reduce the need for ongoing medication. However, the success rates may vary depending on the specific condition being treated and the individual patient's circumstances.

Etymology of CATHETER ABLATION
The word "catheter" derives from the Greek word "kathetēr" which means "something that is introduced or sent down". It can be further traced back to the verb "kathienai", meaning "to send or let down". The term "ablation" originates from the Latin word "ablatio", which means "a carrying away". In the medical context, it refers to the surgical removal or destruction of a body part or tissue. Therefore, the combination "catheter ablation" refers to the procedure where a catheter is inserted into the body to remove or destroy abnormal tissues, usually in the context of treating a cardiac arrhythmia.
