Potential of quantitative flow ratio in guiding conduit selection between radial artery and saphenous vein graft for coronary artery bypass grafting.

ABSTRACT:

Objectives

Radial artery grafts and saphenous vein grafts exhibit heterogeneous responses to competitive flow, a phenomenon assessable through quantitative flow ratio. The present study aims to compare the patency of radial artery and saphenous vein grafts across various quantitative flow ratio ranges.

Methods

The clinical data and quantitative flow ratio values for each target vessel were retrospectively collected in patients receiving radial artery or conventional saphenous vein grafts in our center from 2017 to 2021. The primary outcome was graft occlusion assessed by coronary computed tomography angiography and coronary angiography, and the secondary outcome was major adverse cardiac or cerebrovascular events. Mixed-effect multivariable Cox regression models were used to
