Background—Both radionuclide perfusion tracers and contractile response to dobutamine
have been used to identify hibernating myocardium. The aim was to compare 201 Tl (thallium) …

Objectives : This study characterizes the histology of myocardium predicted to be hibernating
using three different imaging techniques to explain the discordance among them. …

We have validated ECG-gated emission tomography using technetium-99m
methoxyisobutylisonitrile for the assessment of regional ventricular function by comparing it with cine …

SPECT in the assessment of resting left ventricular (LV) function by comparison with cine
MRI. Methods: Twenty-eight patients were recruited prospectively from those referred for …

Aim: We assessed the effects of a 6-week exercise programme on the thallium-201 myocardial
perfusion characteristics of patients following myocardial infarction. Methods: Twenty-five …

Background There has been a revival of balloon aortic valvuloplasty (BAV) for severe aortic
stenosis, as a result of an increasing number of patients undergoing trans‐catheter aortic …

Various clinical trials [1, 2] have confirmed the important role of clopidogrel in the pharmacological
