DH had one this weekend and has just got home. Everything checks out fine. However I am quite surprised at how knocked out he is, he has terrible swelling in his thighs where the catheters were and is hobbling about. He is also very breathless and can't get more than about 10 words out at a try.
It's all to be expected and whilst I'm not worried about him, it would be reassuring to hear from someone who has experience of the procedure if possible.
