Jim, I had a stent placed in the Left Circumflex Artery and in the process my cardiologist found the Right Coronary Artery is 100% blocked near the entrance from the Aorta. The rest of the artery is being supplied by collaterals. Since then, I have been going to Mayo here in Scottsdale Arizona for follow ups. You mentioned Dr. Lynch but do you know the name of the cardiologist who performs CTO PCI procedures here at Mayo?
