Congenital anomalies of systemic veins are usually asymptomatic and found incidentally during ultrasonography, computed tomography (CT) or magnetic resonance examinations performed for other clinical indications. Persistent left superior vena cava (PLSVC) with absent right superior vena cava (RSVC) is the congenital aberration in the thoracic venous system(More)
BACKGROUND The aim of this study was to assess the usefulness of a new ultrasound technique - contrast-enhanced ultrasound examination (US-CE) - using sulphur hexafluoride in the early post-transplant assessment of graft perfusion. Time-intensity curves (TIC) were compared with hemodynamic flow parameters (resistive index: RI) in patients with good early(More)
BACKGROUND AND AIM The study was set out to assess feasibility and diagnostic value of the echocardiographic quantitative analysis of the resting regional systolic function (i.e. strain and strain rate) with use of the speckle tracking (2D strain) for myocardial viability assessment in patients with acute myocardial infarction (MI) treated with primary(More)
BACKGROUND Coronary computed tomography angiography (CCTA) is helpful in making a precise noninvasive evaluation of coronary anatomy, allowing concomitant evaluation of other cardiac structures. The aim of this study was to determine the prevalence of coronary artery variations detected by 64-slice multi detector CT. MATERIALS AND METHODS The results of(More)
INTRODUCTION Even in asymptomatic patients, the result of atherosclerosis progression is deterioration of the function and morphology of the artery wall. Two-dimensional speckle-tracking (2DST) is a sonographic technique that allows for precise evaluation of arterial wall compliance. Together with measurement of intima-media thickness (IMT), it can be(More)
The aim of this article is to describe the clinical presentation and imaging findings of the right-sided aortic arch, an uncommon anatomical variant. We present a case of associated steal syndrome, to our knowledge the first such case in the literature. Diagnostic imaging of a 49-year-old woman with symptoms of cerebrovascular insufficiency revealed the(More)
AIMS To assess whether quantitative resting assessment of local myocardial function by 2D speckle tracking echocardiography may be helpful for the evaluation of myocardial viability in patients after ST-elevation myocardial infarction (STEMI) and for the prediction of left ventricular function recovery after 12-month follow-up. METHODS The study group(More)
We report a case of a 19-year-old patient with double outlet right ventricle (RV) and recurrent giant RV outflow tract pseudoaneurysm, after multiple redo surgery. The patient underwent implantation of a 10 mm Amplatzer Septal Occluder to close the pseudoaneurysm. Postinterventional echocardiography revealed dislocation of the device into the cavity of the(More)
OBJECTIVES Reoperations and catheter interventions after the arterial switch operation (ASO) are relatively rare, but their frequency varies among different centres. They significantly impact the postoperative course of children with transposition of the great arteries (TGA). The aim of this study was to assess the frequency of reoperations and catheter(More)
