Long Term Outcomes and Anticoagulation in Mitral Valve Surgery - A Report from the Society of Thoracic Surgeons Database
CONCLUSIONS: Anticoagulation was used in less than half of mitral valve surgery. In MVrep patients, warfarin was associated with increased bleeding and was not protective against either stroke or mortality. In BMVR patients, warfarin was associated with a modest survival benefit, increased bleeding and equivalent stroke risk. NOAC was associated with increased adverse outcomes.PMID:37308066 | DOI:10.1016/j.athoracsur.2023.05.025

Prominent cardiologist calls for a halt to Watchman implants
A prominent cardiologist is calling for a stop to left atrial appendage closure procedures using Boston Scientific‘s (NYSE:BSX) Watchman device, claiming the procedures, which seek to reduce stroke in patients with nonvalvular atrial fibrillation, result in the opposite. Dr. John Mandrola argues that randomized, controlled trials of the Watchman, designed for LAA closure, showed the device failed to reduce ischemic stroke, despite being designed for just that purpose. “Yet we look away; or we let advocates distract us with complicated statistics,” Dr. Mandrola wrote in an article on Medscape. “Iâ€...

Cost effectiveness of left atrial appendage closure versus Warfarin for stroke risk reduction in non-valvular Atrial Fibrillation in CMS patients
Stroke is the most severe and debilitating consequence of atrial fibrillation (AF), with many patients ranking the resultant disability as worse than death. Warfarin, the established first-line therapy, is effective at reducing ischemic stroke, but is associated with increased bleeding risk and lower quality of life (QoL). Left atrial appendage closure (LAAC) with the Watchman Device has been found to be superior to warfarin at reducing risk of stroke in AF patients. This analysis sought to assess the cost effectiveness of LAAC versus warfarin for stroke prevention in non-valvular AF from the perspective of the US Centers ...

National utilization patterns of warfarin use in older patients with atrial fibrillation: a population-based study of medicare part d beneficiaries.
CONCLUSIONS: Warfarin use rates vary by patient characteristics and region, with higher rates among residents of the Midwest and among patients seen by cardiologists and PCPs. Preventing stroke-related disability in AF requires implementation of evidence-based initiatives to increase warfarin use. PMID: 23324508 [PubMed - in process]
