Year end quiz : What is the name of this Investigation ?

Just role over the virtual marker along the coronary lesion to get the underlying flow ratio. Blue is an absolute normal segment. Green is ok, orange and red slow-moving coronary traffic jam zones. it’s just like drawing a google map showing life traffic. No wire, no adenosine FFR comes inbuilt in every angio shot. Looks great Isn’t it? This is called QFR. Quantitative flow ratio derived from routine coronary angiograms. It can also guide us to find the optimal sites of both proximal and distal stent landing zone in the best physiological manner. Which company makes this ? Any studies done with QFR ? FAVOR 2 study was reported in TCT. This modality is expected to evolve. Final message Whenever possible every anatomical lesion in the coronary should be substantiated by physiological parameter and possibly coronary Imaging to know plaque morphology and vulnerability. Though it is wishful thinking, still for all logistic reasons, most of the real world stenting will be based only on the blind anatomical luminogram. At this point, please let me utter a non-academic hyperbole. Even a casual query to your beloved patients about their true symptoms and exercise capacity shall make these ultra-modern coronary physiology studies redundant in many. A well-performed and well-interpreted stress test is a good, objective,  non-invasive indicator of coronary flow across lesions. It is wise to keep this as a basic clinical foundation in the evaluation of CAD, even as we continu...
