The association of increased stomach wall radiotracer uptake with prolonged use of Omeprazole capsules on myocardial perfusion imaging (MPI) using 99mTc-sestamibi SPECT [PDF]

, 2013
Myocardial perfusion imaging (MPI) is widely used in routine practice for diagnosis and risk stratification of coronary artery disease (CAD). Intense curvilinear activity in the stomach wall of a patient was seen on MPI raw data.

Transthyretin amyloid cardiomyopathy in aortic stenosis patients scheduled for transcatheter aortic valve implantation

ESC Heart Failure, EarlyView.
Abbreviations: TAVI, transcatheter aortic valve implantation; ATTR‐CM, transthyretin cardiac amyloidosis. We aimed to diagnose occult ATTR‐CM in patients with severe aortic stenosis undergoing TAVI using bone scintigraphy. We verified a diagnosis of ATTR‐CM in 8 of 171 (4.7 %) consecutive aortic stenosis patients who underwent TAVI.
