Importance of Femoral Access Method in Predicting the Development of Contrast Induced Nephropathy after Transfemoral Transcatheter Aortic Valve Implantation
Abstract
Introduction:
Transcatheter aortic valve implantation (TAVI) is
more reliable than surgical valve replacement for high-risk or inoperable
aortic stenosis patients. In this study, we aimed to investigate the effects of
different femoral access methods on the development of vascular complications
and contrast-induced nephropathy (CIN) after transfemoral (TF)-TAVI.
Patients
and Methods: In total, 110 patients (aged 78.9 ± 12.2
years; 55 females) who underwent aortic valve replacement by TF-TAVI between
June 2013 and April 2015 were included in the study. CIN was defined as an
absolute increase in serum creatinine level of > 0.5 mg/dL or a relative
increase of > 25% within 48-72 h after TF-TAVI. The patients were classified
into two groups according to the femoral access methods: surgical cut-down
(SCD) and vascular closure device (VCD) groups.
Results:
The amount of contrast medium (CM; p< 0.001) and
the incidence of CIN (p= 0.038) were higher in the VCD group. Baseline
glomerular filtration rate (GFR), baseline creatinine, Mehran score and CM were
determined as the predictive factors of CIN development. Receiver operating
characteristic analysis revealed that CM, which may predict the development of
CIN, was determined as 178.5 mL, and GFR, which may predict the development of
CIN, was determined as 48.9 mL/dk/1.73 m2.
Conclusion:
It may be preferred to perform the femoral arterial
procedure using the SCD method instead of VCD in TAVI patients whose GFR is
< 48.9; the use of CM may increase due to various reasons.
