Key result
A patient's previous renal response to contrast administered during coronary angiogram was not predictive of their change in renal function post-TAVR (r=0.043, P=0.582).
Why the study?
Does the change in GFR following pre-TAVR coronary angiography predict the change in renal function post-TAVR in patients undergoing TAVR?
Population
195 patients who underwent transcatheter aortic valve replacement at a single center between August 2008 and…

Prior contrast response should not guide post-TAVR renal risk assessment; leaves open validation of alternative predictors in prospective cohorts.

Does the change in GFR following pre-TAVR coronary angiography predict the change in renal function post-TAVR in patients undergoing TAVR?
Effect estimate: r=0.043
p-value: p=0.582
A patient's renal response to contrast during pre-TAVR coronary angiography does not predict post-TAVR acute kidney injury; baseline renal function and contrast volume remain the most important predictors.
Marbach et al. (2017) conducted a cohort in Transcatheter aortic valve replacement (TAVR) (n=195). Change in glomerular filtration rate (ΔGFR) post-angiogram was evaluated on Change in renal function post-TAVR (ΔGFR post-TAVR) (r=0.043, p=0.582). A patient's previous renal response to contrast administered during coronary angiogram was not predictive of their change in renal function post-TAVR (r=0.043, P=0.582).
