BACKGROUND The diagnosis of heart failure may be challenging because symptoms are rather nonspecific. Elevated left ventricular (LV) filling pressure may be used to confirm the diagnosis, but cardiac catheterization is often not practical. Echocardiographic indexes are therefore used as markers of filling pressure. OBJECTIVES This study investigated the(More)
BACKGROUND Transcatheter aortic valve replacement has become the procedure of choice for inoperable, high-risk, and many intermediate-risk patients with aortic stenosis. Conduction abnormalities are a common finding after transcatheter aortic valve replacement and often result in permanent pacemaker (PPM) implantation. Data pertaining to the clinical impact(More)
OBJECTIVES The aim of this study was to evaluate the prognostic value of quantitative assessment of pericardial delayed hyperenhancement (DHE) among patients with recurrent pericarditis (RP). BACKGROUND Pericardial DHE on cardiac magnetic resonance may persist beyond the acute phase of pericarditis, suggesting continued pericardial inflammation. METHODS(More)
A rising prevalence of end-stage renal disease (ESRD) has led to a rise in ESRD-related pericardial syndromes, calling for a better understanding of its pathophysiology, diagnoses, and management. Uremic pericarditis, the most common manifestation of uremic pericardial disease, is a contemporary problem that calls for intensive hemodialysis,(More)
BACKGROUND Reversibility of left ventricular (LV) dysfunction in high-risk aortic stenosis patient and its impact on survival after transcatheter aortic valve replacement (TAVR) are unclear. We aimed to evaluate longitudinal changes of LV structure and function after TAVR and their impact on survival. METHODS AND RESULTS We studied 209 patients with(More)
In Response: We thank Fadahunsi et al for their contribution to the field and their interest in our meta-analysis. In our meta-analysis of 23 studies, we had shown that 1-year mortality is comparable in patients with and without permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement. One of the articles included in our(More)
Despite the increase in use of percutaneous coronary intervention (PCI) in left main coronary disease, its efficacy compared with coronary artery bypass grafting (CABG) is unclear. We performed a meta-analysis of randomized controlled trials to assess the optimal revascularization strategy. Our search yielded 8 studies reporting relevant outcomes that were(More)
With so many conditions that can manifest in dementia, the question arises as to how extensive an evaluation need be done on the individual patient presenting with dementia. Thorough physical, neurologic, and psychiatric examinations are the cornerstones of the work-up, with special attention paid to the history, use of medications, and mental status of the(More)
Article history: Received 19 April 2016 Accepted 27 June 2016 Available online 29 June 2016 enlarged cardiac silhouette. Electrocardiogram showed normal sinus rhythm with no abnormalities. Transthoracic echocardiography was notable for pericardial enhancement anteriorly adjacent to the right ventricle and a small pericardial effusion (Fig. 1). Estimated(More)
