ablation

 [ab-la´shun]
1. separation or detachment; extirpation; eradication.
2. removal, especially by cutting with a laser or electrocautery.
catheter ablation radiofrequency ablation.
endometrial ablation removal of the endometrium; methods used include radiofrequency, electrical energy, lasers, and hot and cold liquids.
radiofrequency ablation (radiofrequency catheter ablation) destruction of an accessory conduction pathway or other troublesome area of dysrhythmia by means of unmodulated high frequency alternating current delivered by a bipolar or unipolar catheter. The current causes heat with tissue destruction and formation of scar tissue to block the pathway or dysrhythmic area. Transvenous radiofrequency ablation has been successful in treatment of supraventricular tachycardia and is an attractive option to surgery. Called also catheter ablation.

(ab-lā'shŭn), This word denotes complete removal or extinction, not merely mitigation or reduction.
Removal of a body part or the destruction of its function, as by a surgical procedure or morbid process, or the presence or application of a noxious substance.

Patient discussion about ablation

Q. SVT and AF, Hearts that go fast to slow or any others probs with the beats of any kind and Ablation of hearts I have had Ablation done once and I am still having passing out spells and still on 50mg toprol 2 times a day till two days ago, now I am on 150 to 200 aday again. Its not the first time I have had to up meds. I had ablation down 4/22/05. I can breath better now but but it didnt take it away as you can tell. Now Dr Leonardie would like to do it again . This is the big ????! Will it or can it work 100% this time, or will it hit and miss some again???? MTT

A. Well I can understand the frustration of having to go through this procedure yet another time. There are no guarantees in medicine. You should follow your doctor's advice, as another proceudre might be more helpful than the last one. However you should keep in mind that nothing is for sure.
