What is catheter ablation therapy?

Catheter ablation therapy. You may have this procedure for atrial fibrillation, supraventricular tachycardia or ventricular tachycardia. In this procedure, your doctor identifies the abnormal areas in your heart and then inserts a catheter into your heart, via a large vein in your groin. Heat or freezing treatment is used destroy the area that is causing the abnormal rhythm. The procedure is usually done under local anaesthesia.

How does catheter ablation cure svt?

Rewires the heart. Electrical impulses cause the muscle fibers of the heart to contract and are carried through the heart by special fibers that act like the electrical wires in your home. With svt, often there is an extra fiber present that allows the electrical impulses to bypass the heart's normal circuitry, leading to abnormal rhythms. Using a special catheter, this "extra" fiber can be ablated (destroyed). Read more...
Very effectively. The 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. The catheter tip generates rf energy to scar the heart tissue in a small area, which prevents it from conducting electricity. Read more...

Probably just... Do you mean catheter removal? If so, why did you have catheter in the urethra? If the reason for indwelling catheter is for significant surgery on the urethra and prostate, it is a good idea to refrain from sexual act until the surgical site inside the urethra heals. For detailed general and specific counseling for your concern, please go to see, talk, and work with your urologist. Best wish... Read more...

Electrophysiologist: what would indicate the need for a substrate catheter ablation for some one who is only a paroxysmal afibber? Thanks

Medication failure. If you fail the medication treatment then you have the indication for ablation. Read more...
Symptoms. Intolerable symptoms and failure of medical therapy. From your profile, it would seem that you've failed flecainide. Tikosyn/dofetilide can be used, but ablation is likely to be more effective, especially if combined with meds. If you have no symptoms, i personally wouldn't do it. Read more...
Depends . It all depends on what is driving and or triggering your atrial fibrillation. The standard approach for someone with paroxysmal afib is a pulmonary vein isolation. However, if these patients are put into atrial fibrillation and then ablated with complex fractionated electro gram (CFAE) ablations - sometimes the triggers and substrate for afib are not localized to the region of the pulmonary veins.

What is the definition or description of: catheter ablation?

See below. Ablation from latin means destruction. Most commonly this is applied to cardiac procedures with the goal of preventing recurrent cardiac arrythmias such as atrial fibrillation of flutter. A catheter in introduced via the venous circulation and electrophysiologic studies are performed to precise the site of the focus of electrical disturbance which is then ablated by a strong electrical current.

What are the risks involved with catheter ablation?

Mild to serious. This depends in large part on what exactly is being ablated. Ablation in the right heart is usually a lower risk than in the left heart due to risks of clots in the arterial circulation. All procedures include risk of bleeding, blood clots in a vessel or the heart, and perforation. Atrial fibrillation ablation also poses risk for esophageal or pulmonary vein injury. Read more...
It Varies. In general it is very low risk. There are different types of ablations with varying degrees of risk. Atrial fibrillation ablation tends to carry some of the highest risk of any catheter ablation. Af ablations have a risk of death of 0.15%, tamponade 1.3%, pseudoaneursym 0.9%, stroke 0.2%, TIA 0.7%, pv stenosis 0.3, and ae-fistula 0.04%. There is a small risk of pacemaker in some types as well. Read more...

How long after catheter ablation can I go up and down stairs?

Could ya before? When discharged, unless your instructions say to avoid stairs, then slow steady pace should not interfere with the access site or its clot/scab. Ideally it will have been at least 3 days, if you are on / back on a blood thinner, may want to give it a week to let the repair process get well underway. Any specific q's should be directed to your electrophysiologist. Read more...

How common is it to have a successful catheter ablation procedure?

Depends. The success rates of ablation procedures depend mostly on the rhythm that is being ablated. For some arrhythmias such as SVT or atrial flutter, long term success rates upwards of 95% are very common. Ablation for atrial fibrillation typically results in 1-2 year AF free rates around 70+%. Sometimes a combination of medication and ablation can improve freedom from arrhythmia. Read more...
