Selective coronary angiography: 42 years later

Electrocardiographic changes during selective coronary angiography.

Selective coronary angiography in primary myocardial disease.

Coronary angiography was performed in i6 patients with a primary myocardial disease, Bantu cardiomyopathy. Two patients had discrete coronary occlusion, presumed embolic from ventricular mural thrombus. There was no evidence of coronary atheroma and all the vessels and their proximal intramural branches were large. The total cross-sectional area of the proximal coronary arteries correlated with...

Atrial pacing during selective coronary angiography.

coronary injectiont, and is not, as a rule, associated with depression of atrio-ventricular conduction. Its importance is its relation to several undesirable phenomena which are in part due to it. The first of these phenomena is a decrease in coronary and aortic pressure which, though in most instances of little importance, is appreciable in a significant number of cases: it exceeded 40 per cen...

Indoor radon entry: 30 years later

The paper discusses the results of 30 years of radon indoor entry research. While some progress has been made, many discrepancies between current theories and experimental data still remain. Misconceptions of radon transport mechanisms in homes are analyzed. The role of US Environmental Protection Agency in radon indoor entry research is examined and the agency's policies are criticize...

Coronary Computed Tomography Angiography With Selective Noninvasive Fractional Flow Reserve

Based on review of available data, the Company may consider the use of noninvasive fractional flow reserve (FFR) following a positive coronary computed tomography angiography (CCTA) to guide decisions about the use of invasive coronary angiography (ICA) in patients with stable chest pain at intermediate risk of coronary artery disease (CAD i.e., suspected or presumed stable ischemic heart disea...
