My husband had a cath he has 100% blockage of RAC with collaterals he has 70% diagonal, and 70% of LAD. They said it would be tricky to stent the two on the left and the RCA cannot be stented. He has COPD and surgery is not an option for him. His shortness of breath is much worse and we are going to have a Pet Perfusion study. What will this tell us and what are the risks for stenting the left arteries.
Your husband's situation is not uncommon. Patients with COPD can have difficulty with the recovery from heart surgery; therefore stents are often offered as an alternative. The PET scan will allow your husbands physicians to determine whether the blockages seen in the arteries are severe enough to be limiting the amount of blood flow to the front of the heart. This is a good strategy when there is some question as to whether the blockages are contributing to the patients symptoms. The risk of stenting depends highly on the each individual patient and is quite variable.
