From history of previous stent
to LCX - angioplasty
and now CT angio , multiple calcifications esp in RCA causing 30-40 % stenosis is a significant observation .
Here you will need to asses severity of the lesion by undergoing coronary angiography
- catheter as CT angio is only giving us information about possible lesion .
Catheter Cor angio will clearly tell us about any lesion and whether it is significant to consider for stent .
So plan catheter angiography and further treatment in consultation with your treating cardiologist .
