Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. One of its most devastating complications is the development of thromboembolism leading to fatal or disabling stroke. Oral anticoagulation (OAC, warfarin) is the standard treatment for stroke prevention in patients with AF with an increased stroke(More)
Heart failure as a result of a variety of cardiac diseases is an ever growing, challenging condition that demands profound insight in the electrical and mechanical state of the myocardium. Assessment of cardiac function has largely relied on evaluation of cardiac motion by multiple imaging techniques. In recent years electrical properties have gained(More)
BACKGROUND Degenerative aortic valve (AV) stenosis is the most prevalent heart valve disease in the western world. Surgical aortic valve replacement (SAVR) has until recently been the standard of treatment for patients with severe AV stenosis. Whether transcatheter aortic valve implantation (TAVI) can be offered with improved safety and similar(More)
INTRODUCTION Preoperative anemia is common in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and has been linked to a poorer outcome--including a higher 1-year mortality. The aim of this study was to investigate the impact of successful TAVI on baseline anemia. METHODS A total of 253 patients who survived at(More)
M itral regurgitation (MR) is one of the most prevalent val-vular heart diseases in Western countries. The current estimated prevalence of moderate and severe MR in the United States is 2 to 2.5 million, and it is expected that this number will rise to 5 million by 2030. 1 Surgical intervention is recommended for symptomatic severe MR or asymptomatic severe(More)
Uvod Nakon πto je Andreas Gruentzig revolucionarno upotrijebio balonsku angioplastiku, perkutane koronarne intervencije su postale glavno uporiπte u kardiologiji u sljedeÊim desetljeÊi-ma 1 ; odnosno, sve do nedavno kada je kardiologija usvojila inovacije koje se mogu smatrati jednako revolucionarnim kao i Gruentzigova angioplastika. Ponajprije je razvoj mo
