Interestingly, the lesion that is the nidus for ACS often is not severely stenotic when assessed on the previous angiogram; in fact, two thirds of culprit lesions previously had less than 50% luminal diameter narrowing (and, therefore, would not have been considered appropriate for surgical...

The results of the angiogram divided the patients into groups with little to no coronary blockage (< 20%, LOW CAD), or patients in which coronary blockage was detected (> 20%, MID+ CAD). The blood from the patients was frozen in Tempus blood RNA preservative, thawed, extracted for ...
The angiogram of an eccentric lesion cannot reliably indicate flow adequacy. Other lesions (lower right)may appear hazy but widely patent, only to be responsible for angina due to plaque rupture, as demonstrated by intravascular ultrasound cross-section (far right corner).

To date, the main drawback of FFR pullback–based systems is the lack of a physiology-angiography coregistration to enable accurate location of the sites of hyperemic pressure gradients on the angiogram. Second, the need for motorized FFR pullback still represents a limitation to the widespread ...
