How many times can the heart handle heart ablations?
Would a maze finally end SVT if the many ablations failed>?
What is the purpose of taking a daily asprin if you have a PFO, and why would it help?
Thank you

"How many times can the heart handle heart ablations?"

Good question.

Some individuals on the Net have reported anywhere from 3-5 or more, though that would mainly depend on how many spots have already been treated and the specific area(s).

Here's a randomly-selected example -

Hi Carolyn,

There are several of us who have had five or even more ablations. If it all, ablations do very little damage to the heart muscle and by no chance one could/would burn or freeze the whole heart muscle. The spots that are ablated are usually very small, and the ablation is rather superficial because if they would burn too deep you end up with a tiny hole in your heart. I have had six ablations and my heart muscle is just fine, EF is around 60% which is pretty normal.

In your case there doesn't seem to be a need to ablate again because your av-node is already ablated and pulmonary vein isolations (ablation to treat AF) don't work well in patients who have permanent AF which is why you had your av-node ablated instead.


"Would a maze finally end SVT if the many ablations failed"

MAZE, and any variation thereof, including the paracardioscopic EX-MAZE (PEX) minimally invasive procedure, was designed to treat atrial fibrillation (a-fib/AF), which makes a "maze-like" pattern specifically on the atria.

"What is the purpose of taking a daily aspirin if you have a PFO, and why would it help?"

To prevent/reduce the chance of a brain attack/stroke from occurring. May/can aso be protective form death in that aspect.




It's your there.
James Beckerman, MD, FACC responded:
A MAZE procedure is generally intended to prevent atrial fibrillation. Ablations may be done several times, but it's important to discuss individual details with a doctor.

There is some concern that a PFO or ASD may be associated with a higher risk of stroke, primarily from a small blood clot crossing the septum through the hole, and then going to the brain.

The thinking behind a daily aspirin would be to prevent those clots, and therefore prevent those strokes - there is debate around this however, as there isn't good data to support having everyone with a PFO (upwards of 1 in 5 people!) take an aspirin every day - especially given potential side effects like bleeding.
gailci replied to James Beckerman, MD, FACC's response:
Thank you all very much for your support and answers. What I have been told SVT at times goes into A-Fib for a short time. For the past 6 yrs I thought it would go all away. Whatever God's plan is for me at the age of 53 I wish he would make his mind up. THis is getting old and exhausting.
Many thanks again

You're welcome.

"Whatever God's plan is for me at the age of 53 I wish he would make his mind up."

This brings to mind a saying that I've heard -

Life asks of you what it thinks you can handle, but there are days when you think it has asked too much.

Hope everything works out as well as humanly possible for you, down the road of life.
