Hi has anyone had a CT Angiogram with contrast dye ? Im really anxious as they found a lump on my heart through an echocardiogram. I am v anxious about reaction to the dye also I am extremely difficult for finding a vein for blood tests. I also had an op couple of years ago & they couldn't find a vein for the anaesthetic. They spent over half an hour trying which was stressful & in the end they put me to sleep & then found one. The one they found broke down & luckily I had finished the morphine & had oral meds from then on. My HA will be high before they do the test anyway but if they are struggling to find a vein I will be in a real mess !! Help please.
