Is oral anticoagulation effective in preventing transcatheter aortic valve implantation failure? A propensity matched analysis of the Italian Transcatheter balloon-Expandable valve Registry study
Conclusion After TAVI with Edwards Sapien valve OAT did not reduce the incidence of valve dysfunction and stroke but was responsible for mortality and bleeding increases.

Age-Dependence of Flow Homeostasis in the Left Ventricle
Conclusions: In average, blood spends 1 to 3 beats inside the LV with very low shear stress rates. The apical region is the most prone to blood stasis, particularly in mid-aged adults. The washout of blood in the normal LV is age-dependent due to physiological changes in the degree of apical penetration of the filling waves. Introduction Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis one of its major determinants (Adams et al., 1986). Left ventricular (LV) function has evolved to maximize mechanical efficiency and ensure organ perfusion at a low cost of energy and fill...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Neovasc touts Tiara TMVR success rate in study
A small study of the Neovasc (NSDQ:NVCN) Tiara transcatheter mitral valve replacement (TMVR) in high-risk patients revealed a 100% procedural success rate and immediate elimination of mitral regurgitation. Published in Circulation: Cardiovascular Interventions, the study also showed no death, myocardial infarction, stroke, major bleeding, or access site complications at 30 days. The twelve patients in the study had had a previous aortic valve replacement. Such patients have been excluded from most TMVR trials because of the potential risks of left ventricular outflow tract obstruction or interaction between the TMVR anch...

Transfemoral aortic valve implantation with new-generation devices: the repositionable Lotus vs. the balloon-expandable Edwards Sapien 3 valve
Background New-generation transcatheter heart valves have been developed to reduce complications of transcatheter aortic valve implantation (TAVI). With this study we sought to compare procedural and 30-day outcomes of the new-generation repositionable Boston Scientific Lotus (Lotus) and the balloon-expandable Edwards Sapien 3 (ES3) transcatheter heart valves. Methods A total of 315 patients with severe symptomatic aortic stenosis undergoing transfemoral TAVI with Lotus or ES3 included in two large Italian registries were considered for this analysis. After propensity matching, 93 matched pairs of patients were includ...
