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

Catheter Ablation (Definition)

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 ...Read more

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. ...Read more

What are the risks involved with catheter ablation?

What are the risks involved with catheter ablation?

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

How does catheter ablation cure svt?

How does catheter ablation cure svt?

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

How long after a catheter ablation can I use viagra (sildenafil)?

How long after a catheter ablation can I use viagra (sildenafil)?

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

Question about cardiac catheter ablation, chance of dying during it?

Question about cardiac catheter ablation, chance of dying during it?

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%. Other ablations, like for svt, would be lower risk. ...Read more

Catheter (Definition)

A catheter is a thin plastic tube that is inserted into the body to obtain fluids/blood or give medicine. So some catheters can be placed in the veins and medicine given directly into the body, IV fluids given or blood sampled. A catheter can be placed in the bladder ...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
