Hello and welcome to HealingWell. Thank you for sharing your story and you certainly have a right to be scared and worried about any other damage that may have happened second degree to your heart attack. Catheter ablation is generally safe however it does come with the risk of a heart attack and I am sorry to read that this happened to you.
I understand how you went into the procedure with hope that all would be find only to be dealt a nasty deal. I am glad you are still here talking with us today.
I had major abdominal surgery is August and I read and signed all the forms knowing that on occasion things do go wrong during procedures or surgeries. Never in my dreams did I think that after surgery I would not be able to breathe on my own as I have no lung disease or breathing problems. But there I was on a ventilator and the Drs. were unable to wean me off the ventilator because I did not breathe on my own. 24 hours post-op I was sent uptown to one of the big hospitals and went straight to a pulmonary intensive care unit. My medical history now includes, "Respiratory failure, post-op"
Like you, I am not standing at the front of the line for any type of procedure that may cause respiratory failure again but if I need to have surgery to save my life - I guess I would choose the surgery as I am a gambling gal.
Sending you lots of healing hugs and hope all goes well for you.
