Cardiac magnetic resonance imaging and computed tomography in ischemic cardiomyopathy: an update

Abstract

Ischemic cardiomyopathy is one of the major health problems worldwide, representing a significant part of mortality in the general population nowadays. Cardiac magnetic resonance imaging (CMRI) and cardiac computed tomography (CCT) are noninvasive imaging methods that serve as useful tools in the diagnosis of coronary artery disease and may also help in screening individuals with risk factors for developing this illness. Technological developments of CMRI and CCT have contributed to the rise of several clinical indications of these imaging methods complementarily to other investigation methods, particularly in cases where they are inconclusive. In terms of accuracy, CMRI and CCT are similar to the other imaging methods, with few absolute contraindications and minimal risks of adverse side-effects. This fact strengthens these methods as powerful and safe tools in the management of patients. The present study is aimed at describing the role played by CMRI and CCT in the diagnosis of ischemic cardiomyopathies.

Cardiovascular parameters in capitive blue-fronted amazon parrots (Amazona aestiva, Linnaeus, 1758) with varying body condition scores

“…One of the limitations of this study was the non-use of iodized contrasts during the tomography of the chart. In humans, cardiac CT scans involve the use ionizing radiation and iodized contrasts, representing an important non-invasive method for the diagnosis of atherosclerotic disease [37]. Psittacidae present a high incidence of atherosclerosis [38], a common cardiac disease that is often associated with sudden death to which birds appear to be more susceptible than mammals [39].…”

The Separate Effects of Wall-Thickening and Epicardial Volume as Determinants of Left Ventricular Ejection Fraction

“…As a result, the shrinkage factor becomes β=1-(1-k) 3 , where k is the shortening fraction on the epicardial interface. This is a conservative estimate since the isotropic contractility assumption overestimates the contractility effect.…”

“…Whether it improves global LV function remains controversial. [1][2][3] Although geometric effects have been noted to be important [4][5][6][7], there is no specific model or a model-based set of guidelines to guide surgeons in achieving the optimal shape and size through PLV. In this respect, surgeons use empirical approaches [8] in their approach to improve ventricular shape and size.…”

Asymptomatic apical aneurysm of the left ventricle with intracavitary thrombus: a diagnosis missed by echocardiography

“…It is defined as myocardial ventricular wall thinning and dilation, with distinct margins, leading to akinesia or dyskinesia of one or more myocardial segments during ventricular contraction (1,2-5) . It typically affects the anteroapical region of the LV, because the blood supply of the anterior wall is highly dependent on the anterior descending artery (2,3) .…”
