Hello Aditya Kiran and thanks for writing in at HCM
I am jr. to Cardiologist and like to help you out. You have not written whether you have done CT angiography
or Through femoral or radial angiography. In CT angiography distal arteries are not clearly visible, so it is difficult for surgeon to perform surgery.
For CABG (Coronary Artery
Bypass Grafting) it is very important to know the site of lesion and how's the distal arteries are so that the graft work properly and no complication occur.
In one month their are not much changes that occur unless it 99% stenosis. So it the surgeon who decide better that which angiogram is best for surgery to be performed.
