TAVR Vs Standard Surgery: Midterm Stroke, Death Rates Comparable
All-cause and cardiovascular mortality were similar for transaortic valve replacement compared to open-heart surgery in high-risk older patients at three years with no increased risk of stroke after 30 days, according to results from the PARTNER study presented at the American College of Cardiology's 62nd Annual Scientific Session. The transcatheter aortic valve replacement (TAVR) system was investigated as an alternative to open-heart surgery for high-risk patients with severe aortic stenosis - narrowing of a main circulatory gateway in the heart that reduces blood flow...

Mitral valve repair and bioprosthetic replacement without postoperative anticoagulation does not increase the risk of stroke or mortality ADULT CARDIAC
CONCLUSIONS Despite current guidelines recommending postoperative anticoagulation following MVRR or bioprosthetic replacement, the avoidance of warfarin does not increase perioperative complications and has no impact on intermediate survival. Accordingly, a prospective randomized study to adjudicate the role of extended warfarin thromboprophylaxis in mitral valve surgery is warranted.

COREVALVE reduces rate of death and stroke in sickest patients with aortic stenosis
In a clinical trial, a self-expanding transcatheter aortic valve met the key performance objective of reducing death and stroke in patients with severe aortic stenosis at "extreme risk" for surgery. Results of the COREVALVE EXTREME RISK trial were presented at the 25th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation (CRF), TCT is the world's premier educational meeting specializing in interventional cardiovascular medicine...

Preserved stroke volume late after tetralogy repair, despite severe right ventricular dilatation
To the Editor Right ventricular (RV) enlargement due to increased pulmonary regurgitation has been identified as a significant issue in patients after repair of tetralogy of Fallot. In a recent study, O'Meagher et al1 reported an interesting observation; exercise capacity and stroke volume are maintained with RV end-diastolic volume index (RVEDVi) above, as opposed to below, a commonly used cut-off (150 mL/m2 of RVEDVi) for pulmonary valve replacement (PVR) surgery. They go on to conclude that the optimal timing for PVR remains unclear.1 We agree with their conclusion because the evidence provided by currently availab...

Novel anticoagulants in patients with mechanical heart valves
Commentary on: Eikelboom JW, Connolly SJ, Brueckmann M, et al.. Dabigatran versus warfarin in patients with mechanical heart valves. N Engl J Med 2013;369:1206. Context Novel anticoagulants (including the direct thrombin inhibitor dabigatran etixilate) and oral factor Xa inhibitors have similar or superior efficacy and safety to warfarin for reducing thromboembolic stroke in patients with atrial fibrillation, and for prevention of deep venous thrombosis. Eikelboom and colleagues set out to examine whether these novel anticoagulants could be used as an alternative to warfarin in patients with mechanical heart valves. Method...

Outcomes of surgical aortic valve replacement for severe aortic stenosis: Incorporation of left ventricular systolic function and stroke volume index
We sought to a) assess predictors of mortality in consecutive patients with severe aortic stenosis (AS) undergoing aortic valve replacement (AVR) and b) determine if there are differences in mortality, separated on the basis of different AS subtypes and left ventricular stroke volume index (LV-SVI).

Reducing periprocedural complications in transcatheter aortic valve replacement: review of paravalvular leaks, stroke and vascular complications.
Authors: Paradis JM, Altisent OA, RodÉs-Cabau J Abstract Transcatheter aortic valve replacement has been established as the standard of care for inoperable patients and a valid alternative for high-risk individuals with severe symptomatic native aortic stenosis. Over the last decade, substantial improvement has been made in the transcatheter technology. Nevertheless, this less-invasive procedure is still associated with complications like paravalvular leaks, strokes and vascular complications. This review article discusses these worrisome complications associated with transcatheter aortic valve replacement and pro...

Embolic Protection Devices in Transcatheter Aortic Valve Replacement Contemporary Reviews in Interventional Cardiology
The initially reported periprocedural neurological events rates associated with transcatheter aortic valve replacement raised concerns that ultimately led to the development and to the clinical research of novel embolic protection devices. Although the reduction of clinical stroke is a desired goal, the current research design of embolic protection devices focuses on surrogate markers of the clinical disease, primarily on silent central nervous system lesions observed in postprocedural diffuse-weighted magnetic resonance imaging and cognitive function testing. As the mere presence of particulate debris in brain matter may ...

Carbon Dioxide Flushing Technique to Prevent Cerebral Arterial Air Embolism and Stroke During TEVAR
Conclusion: Arterial air embolism is a potentially underappreciated problem of aortic endografting, especially in the proximal segments of the aorta. CO2 flushing may have the potential to reduce air embolization during TEVAR.

Keystone Heart, Venus Medtech ink Asian TAVR stroke partnership deal
Keystone Heart and Chinese heart valve maker Venus Medtech said today they inked a partnership deal covering China and other Asian markets. Through the deal, the companies will provide Venus Medtech’s transcatheter aortic valve replacement system along with Keystone’s TriGuard cerebral embolic protection device. TriGuard is a cerebral embolic protection device designed to reduce the amount of embolic material entering blood circulation to the brain during TAVR procedures, by allowing blood to pass through while catching potentially dangerous embolic debris. “Providing brain protection for every TAVR pat...
