TL;DR: Emotionally relevant mental stress may be an important precipitant of myocardial ischemia--often silent--in patients with coronary artery disease and further examination of the pathophysiologic mechanisms responsible for myocardian ischemie induced by mental stress could have important implications for the treatment of transient myocardia.

TL;DR: It is demonstrated that Tc-MIBI and TI-201 correlate well on both planar and SPECT images with respect to the identification of patients with coronary artery disease, identification of disease in individual coronary arteries, the presence and severity of perfusion defects, and the assessment of defect reversibility.

TL;DR: The frequency of thallium-201 late reversibility was prospectively assessed in 118 patients who had stress-redistribution thallum-201 studies by single photon emission computed tomography (SPECT), and the frequency of detected reversible defects increased from 27% at 4 h imaging to 43% at combined 4 h and late imaging.

TL;DR: Jet energy correlated linearly with delivered kinetic energy up to 350,000 ergs, at which point velocities started to exceed the extended velocity range and second wrap aliasing occurred, and the relation was not affected by orifice area, gain or compliance, and was only minimally affected by chamber size.

TL;DR: In this article, the ability of color Doppler flow mapping to provide intraoperative information about mitral regurgitation (MR) severity and to evaluate adequacy of mitral valve repair was assessed by performing color doppler echocardiography immediately before and after cardiopulmonary bypass, with the transducer placed directly on the epicardium.
