Cardiac computer models can help us understand and predict the propagation of excitation waves (i.e., action potential, AP) in healthy and pathologic hearts. Our broad aim is to develop accurate 3D MR image-based computer models of electrophysiology in large hearts (translatable to clinical applications) and to validate them experimentally. The specific(More)
Arrhythmias are often associated with healing infarcts and could arise from the border zone of the scars. The main purpose of this work was to characterize the infarct scars using in vivo electro-anatomic CARTO maps (recorded in sinus rhythm) and high-resolution ex-vivo MR images in a porcine model of chronic infarct. The MR images were segmented into scar,(More)
BACKGROUND Diabetes mellitus (DM) and aortic stenosis (AS) are frequent findings in the elderly population. Data regarding the influence of DM on the outcomes of patients undergoing transcatheter aortic valve replacement (TAVR) due to AS are limited. The aim of this study was to examine the impact of DM on TAVR outcomes. METHODS We investigated 443(More)
BACKGROUND The relationship between appropriateness score, treatment strategy and quality of life (QOL) among patients with stable ischemic heart disease (SIHD) is not known. In this prospective cohort study, we evaluated changes in generic and cardiac-specific quality of life in patients with documented SIHD, comparing patients with revascularization(More)
coronary syndrome and undergoing PCI 1 did not show any significant benefit of the trans-radial approach on major bleeding, MACE 2 or mortality [7]. Recently, a randomized study comparing trans-radial to trans-femoral intervention in patients undergoing primary PCI for acute ST-elevation myocardial infarction was presented (TCT 2012). No differences were(More)
