No results posted yet for this study

Summary

The purpose of this study is to investigate the prognostic values of 2-dimensional residual disease patterns determined by quantitative flow ratio (QFR) pullbacks after stent implantation.

Conditions

Interventions

DEVICE

Quantitative Flow Ratio derived PPG and dQFR/ds

From coronary angiographic images, QFR will be calculated and virtual pullback curve will be abstracted and PPG index will be calculated as: PPG index={MaxPPG20mm/△QFRvessel+(1-length with functional disease/Total vessel length) }/2 Physiologic local severity of coronary atherosclerosis was assessed by instantaneous QFR gradient per unit length (dQFR/ds)
