Performing the Left Atrial Maze Ablation Pattern Without Atriotomy.
This report describes a technique how pulmonary vein isolation, an isolation of the posterior left atrial wall and an anterior mitral annular line, which substitutes for the mitral isthmus line in order to prevent perimitral atrial flutter, can be performed during aortic valve replacement without the need for an atriotomy. This technique allows for an optimal time management by minimizing additional cardiopulmonary bypass-time and cross-clamp-time; however, its equivalent efficacy in successfully treating atrial fibrillation compared to the left atrial Maze IV ablation pattern needs to be revealed in future trials.

Artificial aortic valve dysfunction due to pannus and thrombus - different methods of cardiac surgical management.
CONCLUSIONS: Precise and modern diagnostic methods facilitated selection of the treatment method. However, the intraoperative view also seems to be crucial in individualizing the surgical approach. PMID: 26702274 [PubMed]

Atrial Fibrillation Patients Treated With Long-Term Warfarin Anticoagulation Have Higher Rates of All Dementia Types Compared With Patients Receiving Long-Term Warfarin for Other Indications Cardiovascular Surgery
Conclusions The presence of AF significantly increases risk of dementia, including Alzheimer's disease, compared with matched patients receiving warfarin anticoagulation for other reasons. Quality of anticoagulation management remains an important risk factor for dementia in all patients.

Conventional versus Transapical Aortic Valve Replacement: Is It Time for Shift in Indications?
Conclusion For high-risk patients, the TAVI procedure is comparable with conventional AVR, but is not advantageous. These results do not support the expansion of TAVI to low- or intermediate-risk patients.

Study: TAVR safer than surgery in low-risk heart failure patients
Transcatheter aortic valve replacement procedures with self-expanding systems resulted in higher survival rates for patients at lower risk for surgery when compared to surgical aortic valve replacement procedures, according to a study released this month. Results from the study, which compared Medtronic‘s (NYSE:MDT) self-expanding CoreValve TAVR system, were published in JAMA Cardiology this month. The retrospective analysis compared patients from the CoreValve U.S. pivotal high-risk trial of patients with STS PROM scores of 7% or less who either underwent TAVR procedures or surgery, with a median STS Prom score of...

The Challenge of Timing Surgery in Degenerative Mitral Regurgitation Is B-Type Natriuretic Peptide the Solution? ∗
Degenerative mitral regurgitation (MR) with prolapse or flail of mitral leaflets has become the most frequent cause of severe primary MR in Europe and North America (1,2). In its chronic stage, even severe MR is tolerated very well for a surprisingly long time, and patients may remain asymptomatic for years. During this compensated stage of disease, pre-load, afterload, and both contractility and ejection fraction of the left ventricle (LV) remain normal, and the total stroke volume is increased as a result of the compensatory enlargement of the end-diastolic LV volume, which is enabled by an adaptive process of the LV myo...

Exploring unmet needs in venous and arterial thromboembolism with rivaroxaban.
This article will introduce and provide context for these RCTs in the contemporary management of arterial and venous thromboembolism in the following underserved areas: Patients with both NVAF and acute coronary syndrome (ACS) requiring percutaneous coronary intervention (PCI); patients with embolic stroke of undetermined source (ESUS); patients who require transcatheter aortic valve replacement (TAVR); patients with acute or chronic coronary artery disease (CAD; including those with heart failure [HF]); those at risk of or suffering from cancer-associated thrombosis (CAT) and those requiring long-term anticoagulation.

Direct Oral Anticoagulants in Emergency Trauma Admissions.
CONCLUSION: DOACs in the setting of hemorrhage are a clinical challenge in the traumatological emergency room because of the inadequate validity of the relevant laboratory tests. An emergency antidote is now available only for dabigatran. PMID: 27658470 [PubMed - in process]

Trial design: Rivaroxaban for the prevention of major cardiovascular events post transcatheter aortic valve replacement: rationale and design of the GALILEO study
Conclusions GALILEO will test the hypothesis that a rivaroxaban-based antithrombotic strategy reduces the risk of thromboembolic complications post-TAVR with an acceptable risk of bleeding compared with the currently recommended antiplatelet therapy-based strategy in subjects without need of chronic oral anticoagulation.

Atrial Fibrillation Patients Treated With Long-Term Warfarin Anticoagulation Have Higher Rates of All Dementia Types Compared With Patients Receiving Long-Term Warfarin for Other Indications Cardiovascular Surgery
BackgroundThe mechanisms behind the association of atrial fibrillation (AF) and dementia are unknown. We previously found a significantly increased risk of dementia in AF patients taking warfarin with a low percentage of time in therapeutic range. The purpose of this study was to determine the extent to which AF itself increases dementia risk, in addition to long‐term anticoagulation exposure.Methods and ResultsA total of 10 537 patients anticoagulated with warfarin (target INR 2–3), managed by the Clinical Pharmacist Anticoagulation Service with no history of dementia were included. Warfarin indication was for AF (n=...
