Hi all.
A week ago I had a cryoablation for atrial flutter. It was a part of a clinical trial, to see if isolating the pulmonary veins in the left atrium is preferable to the more common right atrium treatment. It involved a transseptal puncture.
After the procedure, the electrophysiologist said that all had gone well.
As part of the trial, I have also had a loop recorder implanted in my upper left chest, with appropriate monitoring equipment.
On the day following the procedure, while still in hospital, I experienced visual auras, similar to those with migraine. Flashing images, seen in either eye and also when both eyes were closed. They would start quite small, almost undiscernable, just of centre in my visual field. They would last around 30 minutes, during which time they would slowly expand to the edge of my field of vision and then dissappear. The patterns could be on the left or right of my visual field but not both together.
I experienced the aura at around 1 am and 7 am. A doctor saw me after both occasions and did basic neurological tests, all of which were OK. I was told that I may have had a reaction to the contrast dye used during the ablation. Drinking plenty of water should flush it out of my system.
The following day, back at home, they happened another 3 times, several hours apart, then settled down.
Unfortunately, this afternoon, after a gap of 6 days I've had another episode of exactly the same sort.
Has anyone else had a similar experience please?
