What contraindications of AF Ablation??

See below: The main contraindication is lack of anticoagulation for 4 weeks prior, but I see you're on Pradaxa. The likelihood of success in permanent AF is low, thus that is a relative contraindication. ...Read more

Ablation (Definition)

Cardiac ablation involves destruction of tissue aimed at elimination of sources of origin or propagation of arrhythmias. It may also be used to destroy part of the heart in hypertrophic cardiomyopathy. Typically it is done with a catheter inserted through a ...Read more

Catheter ablations for wpw?

Catheter ablations for wpw?

Yes: Catheter ablation is considered a first line therapy for symptomatic WPW syndrome. It's highly effective in the majority of cases. It's generally safe with a low incidence of serious complications and since WPW can (rarely) result in sudden death, the benefit of ablation justifies the small risk. ...Read more

What is the indication for surgical ablation (av node ablation) for atrial fibrillation?

What is the indication for surgical ablation (av node ablation) for atrial fibrillation?

Definitive Control: We don't generally do this with surgery, but rather with a "catheter" based procedure (wire we thread into the heart that cauterizes the av node). This procedure provides complete control of the heart rate in the lower chamber and excellent symptom control, but makes people dependent on the pacemaker that *must* be implanted with this procedure. ...Read more

Effect of radiofrequency ablation treatment for heart arrhythmia?

Effect of radiofrequency ablation treatment for heart arrhythmia?

Usually curative: In experts hands, the energy from radio-frequency waves can burn the abnormal electrical pathway or "short circuit" in the heart that is allowing the arrhythmia. ...Read more

Can catheter/cardiac ablation ease pvc's?

Can catheter/cardiac ablation ease pvc's?

Ablation: If PVC's are very frequent and cause a lot of symptoms despite medical therapy , ablation might be an option to decrease symptoms or to suppress the PVC that is causing the problem. ...Read more

Can radio frequency ablation treat svt?

Can radio frequency ablation treat svt?

Yes.: Svt, (supraventricular tachycardia) is a short-circuit of the normal heart conduction pathways. Usually there is a small area that, if removed, would Prohibit the circuit from conducting and therefore block the svt. During ablation, a catheter is placed in this area of the heart, and the tip generates rf energy to scar the heart tissue in a small area, which prevents it from conducting electricity. ...Read more

Better use medtronic adapta or advisa, for paroximal AF patient? I had heart ablation n it was failed, i'm still on AF

Better use medtronic adapta or advisa, for paroximal AF patient? I had heart ablation n it was failed, i'm still on AF

Neither.: Neither Adapta nor Advisa is really an atrial fibrillation treatment device, just "overdrive" atrial pacing, which reduces a. fib. burden. You may want a defibrillator which treats a. fib. like the Evira ICD which can deliver a low grade 50 Hz jolt (you won't feel) or even a shock in the middle of the night, which you will feel, but will get you out of a. fib. Or consider another ablation. ...Read more

What's the difference between catheter ablation and radiofrequency ablation for treating arrhythmias like svt?

What's the difference between catheter ablation and radiofrequency ablation for treating arrhythmias like svt?

General term: Catheter ablation is a general term referring to elimination of electrical conduction in very specific areas of the heart. Two primary technologies are used to perform catheter ablation. Radiofrequency energy is a rapidly alternating electrical current that generates heat at the point of catheter contact. Cryo ablation uses super cooled nitrogen to freeze at the point of of catheter contact. ...Read more

I have paramoxal atrial fibrillation & flutter can it be successfully ablated ?

I have paramoxal atrial fibrillation & flutter can it be successfully ablated ?

AF ablation: Atrial flutter is a simple electrical short circuit in the right atrium and a catheter ablation procedure is very safe and effective (95% permanent cure with one procedure). Atrial fibrillation is a much more complex rhythm pattern and catheter ablation has an average success rate of 70% with a first procedure, with some additional small risks, mostly due to the work being done in the left atrium. ...Read more

After CABG, are allowed to perform AF ablation??

Yes: AF ablation is a non-invasive procedure done by an EP doctor. Howver, while undergoing open heart surgery, other methods exist to rid off AF and/or embolic risk with sutures, etc. ...Read more

How many days must i stoped pradaxa before AF Ablation 3 dimention?

How many days must i stoped pradaxa before AF Ablation 3 dimention?

Variable: Ultimately depends on who's doing the procedure however underlying kidney function and bleeding risk of surgery or procedure helps determining timing. Anywhere from 24 hours in low risk surgery with normal kidney function to 4 days for higher risk surgery in compromised kidney function. Probably in your case about 48 hours but check with your own doctor. Good luck! ...Read more

I'm AF , My EF 60%, I haven't heart attact, no symtomps, no angina& haven't stenting. After CABG & LAA ligation, need anticoagulant or antiplatelet?

I'm AF , My EF 60%, I haven't heart attact, no symtomps, no angina& haven't stenting.  After CABG & LAA ligation, need anticoagulant or  antiplatelet?

Antiplatelets: Usually anti-platelets are the stand treatment to prevent a further heart attack in the setting of a known coronary artery disease and post CABG. Anticoagulants could be used in such instances like atrial fibrillation or history of DVT or PE. Left atrial appendage exclusion reduce but does not eliminate the risk of strokes from atrial fibrillation therefore often times anticoagulants are continued ...Read more

Is endovenous laser ablation procedure painful?

Is endovenous laser ablation procedure painful?

No: There is minor discomfort from the initial puncture and during the course of getting the vein anesthetized. There should be no pain at all when the laser is running. People have varying amounts of bruising and discomfort after the procedure. This is almost never enough to interrupt regular activities. Laser ablation is much easier (both during the procedure and recovery) than surgical procedures s. ...Read more

PCOS, Endometriosis, Heavy Cycles, 33yo, tubal ligation 3 yrs ago. Would an endometrial ablation lessen my symptoms/cancer risks?

PCOS, Endometriosis, Heavy Cycles, 33yo, tubal ligation 3 yrs ago. Would an endometrial ablation lessen my symptoms/cancer risks?

Maybe not: Endometrial cancer can be obscured by endometrial ablations if it is not ruled out prior to the procedure by biopsy. Many women continue to have bleeding post endometrial ablation procedures, and the most likely conclusive treatment is hysterectomy if you no longer desire children. ...Read more

For young (<60), asymptomatic, paroxysmal atrial fibrillation patients on NOACs with LVH, should the patient seek out catheter ablation for treatment?

For young (<60), asymptomatic, paroxysmal atrial fibrillation patients on NOACs with LVH, should the patient seek out catheter ablation for treatment?

Depends: on left atrial size and function, frequency. Ablation is a big deal and frequently unsuccessful. I would try to suppress with a beta blocker like Bystolic, get magnesium level to 2.1-2.4, potassium to 4.1-4.5, stay off stimulants/alcohol, use hawthorne berry, avoid many other supplements, get general labs checked. Why the LVH? HRS, MD, FACC. www.thepmc.org ...Read more
