OBJECTIVE Left atrial size is an important marker for adverse cardiovascular events. There is general consensus that left atrial volume index (LAVI) is the best measurement of size. The current LAVI measurement techniques are laborious. Semi-automated measurement with a 3-dimensional echocardiography (3DE) system may be a practical clinical alternative to(More)
BACKGROUND Low molecular weight heparin (LMWH) is in vast usage for treatment of thromboembolic diseases such as deep venous thrombosis and acute coronary syndromes. There are certain clinical situations where a quick point of care testing of the effect of LMWH would be useful. At this point there are no point of care devices available in the market for(More)
Dabigatran has been associated with greater risk of myocardial infarction (MI) than warfarin. It is unknown whether the increased risk is unique to dabigatran, an adverse effect shared by other oral direct thrombin inhibitors (DTIs), or the result of a protective effect of warfarin against MI. To address these questions, we systematically searched MEDLINE(More)
Decision-making regarding thromboembolism prophylaxis in atrial fibrillation remains a major clinical challenge. While evidence of the beneficial effect of anticoagulation for patients participating in clinical trials is well established, only half of eligible individuals in the general population are currently treated with warfarin. Using an evidence-based(More)
Background Cardiac MR (CMR) has emerged as the gold standard for the evaluation of biventricular systolic function. Semiautomated algorithms for investigating left ventricular systolic function exist, but application to the right ventricle (RV) is challenging. Recently, feature tracking has been developed to semi-automatically track the tricuspid annulus on(More)
Drug-eluting stents (DESs) have decreased the incidence of in-stent restenosis. Within the past 2 years several cases on late stent thrombosis (LST) have been reported. This study analyzed and reviewed all published cases of LST in DESs to explore possible trends not previously reported. We applied a Medline search using the key word "drug eluting stents."(More)
