Diagnostic Performance of Coronary CT Angiography With CT FFR in Kidney Transplantation Candidates

Trial ID: NCT03248674


Patients with chronic kidney disease (CKD) before kidney transplantation require that obstructive coronary artery disease (CAD) is excluded, as cardiovascular complications are the leading cause of mortality in kidney transplant patients. However, in this patient population, the optimal method for the detection of obstructive CAD has not been identified. Noninvasive stress tests such as Dobutamine stress echocardiography or nuclear perfusion study have low diagnostic accuracy. CT fractional flow reserve measurement (CT FFR) is a novel non-invasive (FDA approved) imaging test to identify obstructive CAD. The goal of this project is to evaluate the diagnostic accuracy of CT FFR in the detection of obstructive coronary artery disease in patients with chronic kidney disease before kidney transplantation.
