BACKGROUND The choice of imaging techniques in patients with suspected coronary artery disease (CAD) varies between countries, regions, and hospitals. This prospective, multicenter, comparative effectiveness study was designed to assess the relative accuracy of commonly used imaging techniques for identifying patients with significant CAD. METHODS AND(More)
AIMS Paravalvular aortic regurgitation (AR) is common after transcatheter aortic valve implantation (TAVI). This study aimed to assess the prosthesis/aortic annulus discongruence by three-dimensional (3D) transoesophageal (TOE) planimetry of aortic annulus and its impact on the occurrence of significant AR after TAVI. METHODS AND RESULTS We included 33(More)
AIMS Hybrid imaging provides a non-invasive assessment of coronary anatomy and myocardial perfusion. We sought to evaluate the added clinical value of hybrid imaging in a multi-centre multi-vendor setting. METHODS AND RESULTS Fourteen centres enrolled 252 patients with stable angina and intermediate (20-90%) pre-test likelihood of coronary artery disease(More)
BACKGROUND Two-dimensional (2D) wall motion-tracking echocardiography (WMT) is a useful method to measure myocardial strain, but it is very limited because acquisition and analysis are time consuming. Three-dimensional (3D) WMT is a new method that might improve diagnostic usefulness and reduce study times. The aims of this study were to compare results on(More)
Prosthesis deterioration rate, years after a previous surgical valve replacement, is rising. Usually, the standard management is reoperation, but for very high risk patients an alternative has arisen: the valve-in-valve approach. We present an 84-year-old Caucasian woman with a mitral bioprosthesis (Mosaic II, number 29) since 1994. Over the last few months(More)
Non-invasive cardiovascular imaging initially focused on heart structures, allowing the visualization of their motion and inferring its functional status from it. Colour-Doppler and cardiac magnetic resonance (CMR) have allowed a visual approach to intracardiac flow behaviour, as well as measuring its velocity at single selected spots. Recently, the(More)
BACKGROUND High blood pressure increases left ventricular (LV) after-load. Furthermore, LV response to that high blood pressure varies among different subjects. Nevertheless, myocardial deformation behavior in these different adaptative responses has not been analyzed until now. METHODS Prospective study in which 66 consecutive hypertensive patients were(More)
Given the growing evidence about the use of membrane-covered stents to treat coronary artery aneurysms, it is fundamental to know the exact anatomy of the aneurysm to enable patients to be selected correctly. Invasive heart catheterization has limitations for diagnostic purposes and can underestimate the size of the aneurysm. In this article, we review the(More)
New oral anticoagulants (NOACs) are an alternative for vitamin K antagonists (VKAs) to prevent stroke in patients with non-valvular atrial fibrillation (AF). Unlike VKAs, these anticoagulants do not require routine INR monitoring and possess favorable pharmacological properties. The lack of an effective antidote, their cost, or reservations in patients with(More)
Obesity is considered as a strong risk factor for cardiovascular morbidity and mortality. 3D-wall motion tracking echocardiography (3D-WMT) provides information regarding different parameters of left ventricular (LV) myocardial deformation. Our aim was to assess the presence of early myocardial deformation abnormalities in nonselected obese children free(More)
