Atrial Fibrillation (Definition)

Atrial fibrillation is an irregular and often rapid heart rate that commonly causes poor blood flow to the body. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms include heart palpitations, shortness ...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

O've had two heart surgeries as a child and had an ablation for atrial fibrillation. How often should I see my cardiologist?

O've had two heart surgeries as a child and had an ablation for atrial fibrillation. How often should I see my cardiologist?

Visit returns: Frequency for re checks really depends on the problem(s) and the symptoms. Not knowing what your surgeries were or the success of the ablation it is hard to say. If all has been repaired and no symptoms and sinus rhythm are stable, then yearly visits would likely be fine. If you're having problems, then they would dictate the frequency of return visits. ...Read more

Can cardiac ablation for atrial fibrillation cause damage to the coronary arteries close to the ablation site

Can cardiac ablation for atrial fibrillation cause damage to the coronary arteries close to the ablation site

Yes but it's rare: The coronary arteries, most specifically a branch of the left circumflex artery run directly beneath a structure called the left atrial appendage. Ablation in that region, or just behind it puts rf energy near that artery. However, the artery has very high flow (relatively speaking) and is thus protected from damage the majority of the time. ...Read more

Should I get ablation for my atrial fibrillation and is the robot the right way to go?

It depends: The robot for atrial fibrillation will probably not improve the outcomes of the ablation. It may make the procedure slightly faster, or perhaps less xray use - but the outcomes are about the same as the non-robot ablation. ...Read more

I need to undergo cardiac ablation to treat my atrial fibrillation, how do I select a doctor?

Eectrophysiologist: I agree that an electrophysiologist wil provide the best information regarding catheter ablation. It is important to ask questions regarding outcomes and success rates. I would recommend a university setting for this type of ablation that will provide the best staff as well as equipment. ...Read more

Why would I be completely be dependent on my pacemaker if I have the AV node ablation Such as SVT are atrial fibrillation?

Why would I be completely be dependent on my pacemaker if I have the AV node ablation Such as SVT are atrial fibrillation?

Electricity : The heart is a house with 2 chambers upstairs (atria) and 2 chambers downstairs (ventrical). The electricity to the downstairs chambers comes from the upstairs chamber. The connecting point between the tow floors is called AV node. If you cut this AV node, the lower chambers will not have electricity to work, so u need to provide the lower chamb with anther source of electricity, that is pacemaker ...Read more

What is the success rate for the "firm" procedure for atrial fibrillation and are there any additional risks having it done over a normal ablation

What is the success rate for the "firm" procedure for atrial fibrillation and are there any additional risks having it done over a normal ablation

Alternate technique: My understanding is that FIRM (focal impulse and rotor modulation) ablation is, perhaps, a more advanced ablation system using a very sophisticated catheter that, purportedly, maps locations/rotors that seemingly could trigger & sustain AF. Success up to 80% in controlling AF for 2 years is reported, better than with standard ablation. Risks should be similar. Careful case selection is important! ...Read more

Do you think Atrial Fibrillation would improve with an ablation? Only remedy so far is cardioversion

Yes: RF ablation for atrial fibrillation and/or atrial flutter in good hands ought to be curative. Factors that determine success: electrophysiologists experience and record of success, duration of AF; size and function of Left atrium. Good luck! ...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
