Has anyone had the cryoablation proceure for A-Fib or SVT..?

I know radio frequency (heat) ablation has been around for awhile- bt the cryoablation (cold)- is supposed to be both safer (does not permanently damage surrounding tissue)- and is more speficic in the areas ablated-!

I have an appt to see my EP cardiologist next week--

My two main questions---are--

1) During the cryoablation are you "out" completely...? Or in a kinda semi fog..?
I really wish that the Drs--would just put me out & then- come out when it's over !... I reallly do NOT wanna be -in any way--awake--!!

2) How long do you have to wait-after the procedure..(weeks or months) until the scar tissue forms--& creates a "block" of the bad electrical pathways!

I am afraid-- but--I can NOT go on living this way--with the constant fear--of getting an SVT attack--!

Hoping someone--who has had this...procedure--gets back & write(in as much detail as possible)----& aside from the two questions I asked -- was it ..effective in eliminating--if not least most of the irregular heartbeat-! smhair

Since I;ve gotten no response--I;ve gone back to past posts--!

It seems all the Ablations have been "Radio Frequency" (RF) ablation--which uses heat--!

The newer "Cryoablation" uses "COLD"...& has much less side effects-- does not damage surrounding heart tissue...(and esophagus) !

It has had great reviews--Soooo ...I was (And still am) or two.(or more)-- people have had the "Cryoablation"--With better results--

Thanks--Hoping to..hear--! Regards--Rob...(Wotan)-

RF isn't heat, per se, it's radio frequency energy. I've been burned (contradicting myself already) by RF Energy, it's not like it's a soldering gun type heat, it's an RF effect.

I searched for "cryoablation of arrhythmias NIH" (National Institutes of Health) and found the following link. There are many more links found this way as well. Hope this is of some use to you. I enjoy researching, if you post back, I'll be glad to try to answer your questions. As fast as being awake, I understand that varies by circumstances, but the anesthetics they have today make conscious sedation possible and is so profound that it is unlikely you'd be concerned during the procedure.

"Catheter cryoablation is a safe and clinically effective method for ablation of atrioventricular nodal reentrant supraventricular tachycardia. Although the acute procedural success rate of catheter cryoablation for this arrhythmia may be slightly lower than that reported for radiofrequency ablation, it has an excellent safety profile, with no reported instances of inadvertent atrioventricular block requiring implantation of a permanent pacemaker." (Very interesting, I've never heard of cryoablation before, but have read of the AV issue with RF Ablation).

Using this technology, one can perform reversible cryomapping, which helps to identify suitable ablation targets while identifying sites where cryoablation should be avoided. For patients with midseptal and parahissian accessory pathways, in whom the risk of producing inadvertent atrioventricular block is substantial, catheter cryoablation is a safe and effective alternative to radiofrequency ablation. Catheter cryoablation of common atrial flutter causes much less patient discomfort than radiofrequency ablation, with excellent acute and long-term efficacy. Catheter cryoablation also can be used to isolate the pulmonary veins during ablation of atrial fibrillation. As compared with radiofrequency ablation, the risk of acute thromboembolic complications and of pulmonary vein stenosis appears to be lower with cryoablation."

I am sorry to hear of your anxiety and your concern I can appreciate. I have never had an ablation, but have been "semi under" for an EP study done back in '98. cry . I have suffered from PVCs and PACs for a long, long time. I was also "semi-out" for my cath in '03.
Both times, I had excellent care, and both doctors were Excellent performing their procedures. I still have the ectopic beats, and during this lastest "horrid cycle" of PVCs was considering ablation, but my current Cardiologist, said that under 20,000 PVCs a day, and the ablation is not done. I don't know. This seems like an awful lot of ectopics to deal with daily. My worst day on a 41 hr monitor of recording, was 5300. My thoughts and hopes for you to feel better are with you and I wish you well on your procedure. :-)
