Thanks everyone.
I do have some good news afterall
I had tried a few, including covermore, but as it was declined by one, then it will be declined by all and many wouldn't even look at it because it is a condition concerning arteries, it's considered too high risk and they will not go near it. Even though it has healed but it is recent!
I am still hoping to hear back from the original one I applied with, they are reviewing the denial after I faxed off some additional information, so hopefully they will return with a change of heart (and a higher premium probably but that is fine).
Anyway the good news is, that as we booked and paid for 50% of the trip from December to April of this year with our visa, this was before the condition happened, then they will cover the pre existing condition as it was not existing when more than 50% of the trip was paid
So the trip is still on
Was a little depressed last night thinking it would have to be put off until December or even April or September next year (as soon as enough time had passed for it to nolonger be a pre existing condition).
