So good to hear from you and really happy that you have taken the time to respond. I am praying for your husband that the spot turns out to be just an old scar because when I had the balloon angioplasty last year, my arteries were ruptured and if I have to go to another emergency department, they think that the spots are new clots but it is just the scars from the ruptures. I am 54 years old turning 55 next month. I have had this PH since I was 31…that was when they found the 2 clots in my lungs and the doctors did not diagnose PH..they inserted an IVC ( inferior vena cava) filter into my chest in 2003. I received a letter from Health Canada that the filters were recalled so I did some tests on Thursday and next Thursday, I will see the vascular surgeon to get the results. I will keep you updated and I hope you guys get the positive results that we are hoping for and please tell your husband to keep smiling and God never gives us more than we can endure. It is a test of faith. God bless and hope to hear from you soon. ..
