Claret Medical files for FDA clearance for Sentinel cerebral protection device
Claret Medical said today that it filed an application with the FDA seeking 510(k) clearance for its Sentinel cerebral protection system designed for use during transcatheter aortic valve replacements. The Santa Rosa, Calif.-based company’s Sentinel device is designed to capture and remove embolic debris dislodged during TAVR procedures, which can enter cerebral circulation and can potentially lead to strokes. “Our contribution in building significant new science will help the rapidly growing TAVR field embrace the critical role of cerebral protection in all left heart and endovascular procedures. These studi...

Rationale and design of the Transcatheter Aortic Valve Replacement to UNload the Left ventricle in patients with ADvanced heart failure (TAVR UNLOAD) trial
Publication date: Available online 26 August 2016 Source:American Heart Journal Author(s): Ernest Spitzer, Nicolas M. Van Mieghem, Philippe Pibarot, Rebecca T. Hahn, Susheel Kodali, Mathew S. Maurer, Tamim M. Nazif, Josep Rodés-Cabau, Jean-Michel Paradis, Arie-Pieter Kappetein, Ori Ben-Yehuda, Gerrit-Anne van Es, Faouzi Kallel, William N. Anderson, Jan Tijssen, Martin B. Leon Background Co-existence of moderate aortic stenosis (AS) in patients with heart failure with reduced ejection fraction (HFrEF) is not uncommon. Moderate AS increases afterload, while pharmacological reduction of afterload is a pillar of contemporary...

Incidence and risk factors for thromboembolism and major bleeding in patients with mechanical valve prosthesis; a nationwide population-based study
Conclusions In a nationwide cohort study with MHV and high TTR, heart failure and atrial fibrillation did not appear as risk factors of stroke/TE.

Zebrafish models of cardiovascular disease
AbstractCardiovascular disease (CVD) is one of the leading causes of death worldwide. The most significant risk factors associated with the development of heart diseases include genetic and environmental factors such as hypertension, high blood cholesterol levels, diabetes, smoking, and obesity. Coronary artery disease accounts for the highest percentage of CVD deaths and stroke, cardiomyopathies, congenital heart diseases, heart valve defects and arrhythmias follow. The causes, prevention, and treatment of all forms of cardiovascular disease remain active fields of biomedical research, with hundreds of scientific studies ...

Novel Oral Anticoagulants in Atrial Fibrillation: Update on Apixaban.
Authors: Mezue K, Obiagwu C, John J, Sharma A, Yang F, Shani J Abstract Almost 800,000 new or recurrent strokes happen every year. Atrial fibrillation, the most common cardiac arrhythmia, is a major risk factor for stroke, accounting for 15-20% of ischemic strokes. Apixaban is a direct inhibitor of Factor Xa that was approved in December 2012 by the US Food and Drug Administration (FDA) for the prevention of stroke in patients with non-valvular atrial fibrillation. It is part of a family of novel oral anticoagulants (NOACs) which have the advantage over warfarin of less dosing variability, rapid onset of action and...

Critical Role of Coaptive Strain in Aortic Valve Leaflet Homeostasis: Use of a Novel Flow Culture Bioreactor to Explore Heart Valve Mechanobiology Cardiovascular Surgery
Conclusions Failure of AV to close initiates an extensive response characterized by expression changes common to progression to calcific aortic valve disease. AV coaptation, whether phasic or chronic, preserved phenotypic gene expression. These results demonstrate, for the first time, that coaptation of valve leaflets is a fundamentally important biomechanical cue driving homeostasis.

Improving outcomes: case-matched comparison of novel second-generation versus first-generation self-expandable transcatheter heart valves ADULT CARDIAC
DISCUSSION TF-TAVI was feasible and safe using this new type of nitinol-based THV. Superiority to the current generation of self-expanding THVs was achieved regarding post-interventional pressure gradients and EOA, severity of residual PVL and rate of PM implantation. Results set a promising quality standard for TF-TAVI with a self-expanding THV, but will have to be confirmed in a larger patient cohorts for further clinical evaluation.

'Nine out of 10 strokes preventable,' claims study
Conclusion This valuable research aims to clarify which preventable risk factors are associated with stroke risk – knowledge that could have an effect on addressing this important global health problem. The study's strengths are that it is based on a large sample size of nearly 27,000 people from 32 countries and of different socioeconomic backgrounds. The researchers made careful attempts beforehand to calculate how many participants they would need to include to be able to reliably detect differences in risk factors. There was little missing data across the total sample – for the various different risk factors as...

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.

Thirty-day outcomes in patients at intermediate risk for surgery from the SAPIEN 3 European approval trial.
CONCLUSIONS: TF-TAVI using the SAPIEN 3 THV in patients at intermediate risk for surgery is associated with a very low risk of death and complications, including new pacemakers and paravalvular leaks. Although compelling, these initial results are being confirmed in larger global studies before expanding the indications for TAVI in severe aortic stenosis. PMID: 27290682 [PubMed - in process]

WITHDRAWN: Preoperative statin therapy for patients undergoing cardiac surgery.
CONCLUSIONS: Preoperative statin therapy reduces the odds of postoperative atrial fibrillation (AF) and shortens the patient's stay on the ICU and in the hospital. Statin pretreatment had no influence on perioperative mortality, stroke, myocardial infarction or renal failure, but only two of all included studies assessed mortality. As analysed studies included mainly individuals undergoing myocardial revascularisation, results cannot be extrapolated to patients undergoing other cardiac procedures such as heart valve or aortic surgery.
