We performed a double-blind randomized trial comparing high doses of subcutaneous heparin (12,500 units every 12 hours) with low (5000 for 10 days in the prevention left ventricular mural thrombosis 221 patients acute anterior myocardial infarction. Left was observed by two-dimensional echocardiography on 10th day after infarction 95 (11 percent) high-dose group and 28 88 (32 low-dose (P = 0.0004). One patient four had nonhemorrhagic strokes 0.17). fatal pulmonary embolism. There no...

The objective of the present study was to compare midterm follow-up results percutaneous coronary intervention (PCI) and bypass graft surgery (CABG) for treatment unprotected left main artery disease in octogenarians.A total 249 consecutive patients > or =80 years age diagnosed with underwent revascularization our center between January 2002 2008; 145 CABG, 104 had PCI. Major adverse cardiac cerebrovascular events (MACCE [cardiac death, myocardial infarction, event, revascularization]) were...

Study Objective: To determine the efficacy and safety of adjusted subcutaneous calcium heparin compared with continuous intravenous as initial treatment for acute deep vein thrombosis. Design: Randomized control trial. Setting: University-affiliated general hospital. Patients: Of 111 consecutive patients considered, 103 had proximal or calf thrombosis confirmed by ascending venography met all other eligibility criteria. Interventions: Patients were randomly assigned to receive heparin. The...

Mild-to-moderate aortic regurgitation (AR) is not infrequently encountered after standard valve replacement, and reportedly more often following transcatheter implantation. Patients are usually managed by observational follow-up, but the clinical significance natural history of residual AR unknown. The goal this study was to determine its impact on outcome these patients. Between 1992 2011, 3201 consecutive patients underwent isolated replacement in our institution. Of these, 135 (4.2%) were...

Background The influence of coronary artery disease (CAD) on clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) is still controversial. We sought to evaluate the impact CAD severity as measured by SYNTAX score ( SS ) patients undergoing TAVR . Methods Results A total 377 who underwent in 2 high‐volume centers North America were included our retrospective analysis. blinded angiographic core laboratory calculated all available angiograms with use...

Deep brain stimulation (DBS) of the basal ganglia is an evolving technique for managing intractable movement disorders such as those due to Parkinson disease. We conducted a retrospective review DBS procedures that have been performed at our institution determine frequency and types complications occurred.After Institutional Review Board approval, 258 involving 250 patients were retrospectively reviewed. Univariate analysis using chi test categorical variables t-test continuous was on with...

In Brief Improvements in airway imaging technology provide the potential for an improved understanding of pathology and upper mechanics. We present here a preliminary report on applicability cone beam computed tomography conjunction with multidimensional digital analysis purposes clinical management. The use this anesthesiology has not been reported. Traditional skeletal soft tissue images as well distance volume measurements were obtained without difficulty. Three-dimensional image...
