So, my mom was diagnosed with 80% stenosis in the mid RCA and there's also a 50% instent restenosis in the distal RCA, where she had a stent put in back in 2010. We're a bit confused because one doctor is suggesting she should go through angioplasty again for both areas, while another doctor thinks it's not necessary. This is pretty stressful, and I really want to make the right decision. Could you explain what the typical approach is for handling instent restenosis and how serious this situation looks?

RCA STENOSIS 80% IN MID SEGMENT WILL INFLUENCE EFFECT OF DISTAL STENOSIS. ONCE U OPEN MID RCA LESION WITH BALOON AND DO ANGIOPLASTY THEN CHECK THE INSTENT RESTENOSIS LESION WITH FFR. IF FFR IS MORE THAN O.8 THEN NOTHING FOR DISTAL AND IF FFR IS LESS THAN 0.8 ANGIOPLASTY TO INSTENT RESTENOSIS.
