[68Ga]Ga-FAPI PET to detect early myocardial fibrotic activity in patients with severe aortic stenosis undergoing TAVR
Aortic stenosis (AS) causes ongoing pressure overload on the left ventricle and leads to progressive myocardial remodeling. Early diffuse interstitial fibrosis often remains difficult to detect with conventional imaging techniques. Fibroblast activation protein (FAP)–targeted positron emission tomography (PET) ca...
