Three quinquagenarians who underwent insertion of a left ventricular assist device (LVAD) because of severe heart failure and for whom histologic examination of the left ventricular apical " core " (removed to insert the device) showed noncaseating giant cell granulomas typical of sarcoidosis are described. Later, cardiac transplantation showed widespread(More)
AIM To assess whether under-use of coronary artery bypass graft (CABG) or percutaneous transluminal coronary angioplasty (PTCA) affects patient outcome. PATIENTS AND METHODS A prospective observational study was performed following up a cohort of patients, candidates for a revascularization procedure (either CABG or PTCA) after an index angiogram. A total(More)
Measurement of diffusion and its dependence on direction has become an important tool for clinical and research studies of the brain. Diffusion imaging of the spinal cord may likewise prove useful as an indicator of tissue damage and axonal integrity; however, it is more challenging to perform diffusion imaging in the cord than in the brain. Here we report(More)
BACKGROUND The advancing age and generally increasing risk profile of patients receiving isolated coronary artery bypass graft (CABG) surgery is expected to raise incidence of new-onset postoperative atrial fibrillation (AFIB) resulting in potentially higher risk of adverse outcomes. In the early postoperative course, new-onset post-CABG AFIB is considered(More)
BACKGROUND There is debate concerning whether an aneurysmal ascending aorta should be replaced when associated with a dysfunctioning aortic valve that is to be replaced. To examine this issue, we divided the patients by type of aortic valve dysfunction-either aortic stenosis (AS) or pure aortic regurgitation (AR)-something not previously undertaken. (More)
Performances of some common confidence interval construction procedures for direct standardized incidence or mortality rate were compared. The asymptotic method, the method based on matching moments, the method based on gamma distribution and the method based on beta distribution were investigated through Monte Carlo simulations based on data from an(More)
OBJECTIVE To examine changes in representation of women among first authors of original research published in high impact general medical journals from 1994 to 2014 and investigate differences between journals. DESIGN Observational study. STUDY SAMPLE All original research articles published in Annals of Internal Medicine, Archives of Internal Medicine,(More)
removed ≈5% of death records from its Death Master File and started excluding ≈40% of new death records, having determined that data submitted electronically by states cannot be publicly shared. Before this determination , the Death Master File provided an accessible source of national vital status data with a short time lag and high specificity and(More)
BACKGROUND The Society of Thoracic Surgeons (STS) is developing a portfolio of composite performance measures for the most commonly performed adult cardiac procedures. This manuscript describes the third composite measure in this series, aortic valve replacement (AVR) combined with coronary artery bypass grafting surgery (CABG). METHODS We identified all(More)
Cardiac transplantation (CT) has been one of the great medical advances of the last nearly 50 years. We studied the explanted hearts of 314 patients having CT at Baylor University Medical Center Dallas from 1993 to 2012, and compared the morphologic diagnoses to the clinical diagnoses before CT. Among the 314 patients the morphologic and clinical diagnoses(More)
