DIFFERENTIAL DIAGNOSTIC ACCURACY OF RESTING NON-HYPEREMIC PRESSURE RATIOS (NHPR) IN RCA VERSUS LEFT CORONARY LESIONS

Diagnostic accuracy of NHPRs including Pd/Pa, iFR and RFR is ~80% when compared to FFR. The differential performance of NHPR among the different coronary arteries has been observed but not systematically studied. We evaluated the comparative performance of Pd/Pa against the reference standard of FFR
