Pre-discharge (18)F-Flourodeoxyglucose uptake pattern following transcatheter aortic-valve replacement and adverse prognostic features in aortic stenosis

(18)F-Flourodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) has been shown to be of utility in transcatheter aortic valve replacement (TAVR) patients with suspected prosthetic valve endocarditis. In the present study, we sought to analyze the relationship between (18...

Descripción
Sumario:(18)F-Flourodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) has been shown to be of utility in transcatheter aortic valve replacement (TAVR) patients with suspected prosthetic valve endocarditis. In the present study, we sought to analyze the relationship between (18)F-FDG-PET/CT performed before discharge in TAVR patients and adverse prognostic features of aortic stenosis. We analyzed the association between (18)F-FDG-PET/CT uptake pattern and degree of left ventricular mass index, aortic root dilatation, and aortic leaflet calcification extent. This is the first study to demonstrate that pre-discharge (18)F-FDG-PET/CT in patients undergoing TAVR shows a significant negative correlation between (18)F-FDG uptake pattern and adverse prognostic features.
