Curative intermediate-term outcomes are possible in dogs undergoing open tricuspid valve replacement with a bioprosthesis. Prosthesis-related complications include inflammatory pannus, thrombosis, and endocarditis. Postoperative atrial fibrillation or flutter can be reduced or prevented by prophylactic preoperative treatment with amiodarone. Several identified complications are avoidable or can be reduced with increased awareness and experience with these techniques.

This study was performed to ascertain the incidence of anticoagulant use in oculoplastic surgical patients and the reliability of patient medication disclosure. Differences in perioperative bleeding complications among patients continuing anticoagulants, those who withheld the medications, and those not anticoagulated were investigated.

During follow-up bleedings occurred in 47 (60.3%) patients, 26 patients (33.3%) had recurrent bleedings at therapeutic INR and 21 patients (26.9%) had single bleeding. Mean time in therapeutic range (TTR) was >70.

An ANN was applied to develop a warfarin dosing algorithm. The proposed dosing algorithm has the potential to recommend warfarin dosages that are close to the appropriate dosages.

This study sought to investigate the outcomes following cardioversion or catheter ablation in patients with atrial fibrillation (AF) treated with warfarin or rivaroxaban.

Our objective was to determine the rate of intracranial bleeding in anticoagulated patients with minor and minimal head injuries and the association with clinical features and international normalized ratio (INR).
coumadin drug test
The prospective use of the first-generation American Academy of Orthopaedic Surgeons guidelines resulted in a low incidence of clinically important thromboembolic events in total hip and total knee arthroplasty patients. When properly used in these patients, the guidelines to minimize adverse outcomes are executable and effective.

Our aim was to identify risk factors for acute gastrointestinal (GI) bleeding in patients with myocardial infarction (MI) who were prescribed clopidogrel following hospital discharge.

To compare the bleeding risk after cold snare polypectomy or conventional polypectomy for small colorectal polyps in anticoagulated patients.

Despite increasing scientific investigation, the best method for preventing postoperative thromboembolism in patients undergoing a total hip replacement (THR) remains unclear. National Institute for Health and Clinical Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN) guidelines on the prevention of thromboembolism have caused much controversy. We surveyed Scottish surgeons regarding their thromboprophylaxis prescribing after THR. Questionnaires were sent to all Scottish orthopaedic consultants. They were asked about routine pharmacological and mechanical prophylaxis in patients undergoing a THR. Comparison was made with a previous survey done in 2003. The response rate was 75%. The survey showed an increased use of pharmacological prophylaxis from 93% to 100%. This was due to the increased use of aspirin from 51% to 64%. The use of low molecular weight heparin has remained constant at 51%. No surgeons routinely use warfarin, un-fractionated heparin or fondaparinux. Use of graded compression stockings has increased from 59% to 70%. In conclusion, there is increasing evidence that patients undergoing THR should receive extended prophylaxis for up to 35 days. Oral agents such as dabigatran and rivaroxaban have offered a new option for oral extended prescribing. The results in change of practice must be closely audited.

Eighteen consecutive patients receiving long-term stable warfarin therapy were enrolled in this study. AZ-ER was administered 1 hour prior to tooth extraction. The international normalized ratio (INR) value was measured prior to AZ-ER administration as well as during, 1 day after, and 7 days after the tooth extraction. Additionally, the azithromycin concentration in the extraction wound as well as in the peripheral venous blood was assessed.

NVAF patients ≥ 18 years of age with continuous insurance coverage were identified (January 1, 2007, to December 31, 2009) from the MarketScan Commercial and Medicare Research databases. Patients with 1 inpatient or 2 outpatient dyspepsia diagnoses within 12 months following any NVAF diagnosis were grouped into the dyspeptic cohort, and patients without any dyspepsia diagnosis were grouped into the nondyspeptic cohort. Of the overall cohorts, patients were matched by key patient characteristics. Dyspepsia was further categorized as having a prior history of dyspepsia (chronic) or no dyspepsia (nonchronic) during the baseline period. Health care resource utilization, associated costs, and warfarin use were evaluated during a 12-month follow-up period.

In the Randomized Evaluation of Long-term Anticoagulant Therapy (RE-LY) trial, dabigatran 150 mg was shown to be superior to warfarin for the prevention of stroke or systemic embolism. However, there are some concerns with the RE-LY trial, such as its open-label design, potential unblinding of "blinded" adjudicators, the use of concomitant warfarin-aspirin (ASA), the disparity between baseline use of nonselective NSAIDs; the high unequal rate of drop-outs; unaccounted drop-ins; high rates of major bleeds in warfarin-treated patients, despite being a low risk population; and rates of major bleeds that do not match historic warfarin trials. Furthermore, although dabigatran offers potential advantages versus warfarin, there are disadvantages that must be taken into consideration before a patient is switched from the latter to the former. This review will summarize the flaws of the RE-LY trial as well as the clinically important advantages and disadvantages of dabigatran and warfarin.

Only one-fifth of patients who present with chest pain or suspected ACS have ACS as their final diagnosis. Our new guideline proposal is highly specific and would minimize unnecessary administration of potent anti-thrombotic therapy to low risk patients.
Advanced age alone should not exclude the use of dabigatran. Clinicians should base their decision on patient characteristics and careful assessment of risk versus benefit.
