FFR then reflects friction and separation co efficients of the stenosis. This isn’t the haemodynamic state of a blocked vessel

The distal bed of a Cx CTO is supplied by 3 sources (may not be seen on an angiogram due to its poor spatial resolution). Collaterals from prox vessel, ipsilateral vessel and contra lateral vessel.

I’d love to hear his thoughts.

Lack of ischaemia commensurate with an FFR of 0.4 in Cx region on MRI influenced decision making. Should the Cx region have had an FFR of 0.4 the collateral flow requirement from the RCA would be significant and would make RCA iFR/ FFR very positive?
