Intravascular ultrasound for evaluation of coronary arteries
Intravascular ultrasound (IVUS) has emerged from a research tool to an intrinsic part of modern invasive cardiology. The main reason is the capability to obtain “in-vivo” histology. For the first time it is po...

Quantification of mitral valve stenosis by three-dimensional transesophageal echocardiography
The aim of this study was the evaluation of the diagnostic potentials of transesophageal 3D-echocardiography in the determination of mitral valve stenosis. 54 patients were investigated by transthoracic and mu...

Left ventricular contrast echocardiography — echoventriculography — stress echocardiography
Echographic contrast agents were first used for structure identification [1, 2], and pooled data analysis revealed a high level of safety [3]. Special agents have been developed in order to standardize right h...

RETRACTED ARTICLE: Role of intravascular ultrasound imaging in identifying vulnerable plaques
A plaque that has a large lipid core and a thin fibrous cap may undergo rupture. Once it ruptures, it may lead to thrombus formation and subsequent vessel occlusion. To identify unstable plaques before they ru...
