The role of 64-MSCT in the diagnosis of cardiomyopathies (CM) using both coronary angiography and cardiac function tools.
Background
Cardiomyopathies (CM) are chronic, progressive myocardial disease with distinct patterns of morphological, functional, and electrophysiological changes. Determining the exact aetiology, in particular ruling out the presence of coronary disease, is important because it affects directly treatment and patient prognosis. Patient management in ischemic disease may benefit from revascularization, aneurysmectomy, and secondary preventive pharmacotherapy, whereas patients with non ischemic CM may have better response to beta-blockade. Determining the exact aetiology, however, can be difficult using currently available imaging techniques, such as echocardiography, radionuclide imaging or X-ray...
Imaging findings OR Procedure details
Our poster shows how VCT-64 slices MDCT scanner allows the assessment of both coronary arteries and cardiac function in one stop shop. 1° case: An example of post myocardial ischaemia with diskinetic thin apex resulting in initial aneurysm. CT angiography reconstructions demonstrates chronic occlusion of middle LAD right after D1. CT functional studies have been compared to MR imaging with substantial equivalence regarding functional cardiac parameters (EDV, ESV, EF) and the wall score. 2°case: An example of post-ischaemic dilated cardiomyopathy with a large area of...
Conclusions
64-MSCT is an appropriate imaging study for CM in diagnosing ischemic CM that is associated with shorter mean survival relative to non-ischemic CM VCT 64 slices scanner allows us: rule out the underlying ischaemic disease in patients with dilated cardiomyopathy by the evaluation of the coronary tree. obtain quantitative parameters of the ventricular function. evaluate regional kinetics. follow-up of patients with pacemaker who can’t undergo MR study.
