[|Human|] When you are diagnosed with calcification of the arterial vessels around the heart, is there anything you can do? 5 Bypass surgery done 30 years ago is completely closed. Other vessels on right side of the heart are 90% closed. Blood flow is being carried mainly by collateral vessels.
[|AI|]  Hi, Bypass surgery grafts can get blocked by a thrombus or can accumulate calcium over a long period of time.  As you are saying that all grafts are blocked and the right artery is also significantly blocked you will need further treatment for the same.  I can only tell you better if you send me a detailed Angiography report.  Angioplasty could be tried in a native blocked vessel or calcified vessel by a technique called as Rot ablation. So please send me the detailed report of Angiography if possible. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
