Research Article: The functional impact on donor vessel following transcatheter closure of coronary artery fistulas—a retrospective study using QFR analysis
Abstract:
Background: The impact of transcatheter closure of coronary artery fistula (CAF) and residual shunt after occlusion on improving blood flow in the donor vessel remains uncertain.
Introduction:
Objectives: To evaluate the functional impact on the donor vessel following CAFs closure using QFR (Quantitative Flow Ratio) analysis.
