Polymeric Transcatheter Heart Valves
… Commercial bioprosthetic valves (surgical and transcatheter) suffer from calcification and decreased durability, especially when implanted into younger patients, while mechanical surgical valves require life-long anticoagulation. Polymeric transcatheter aortic valve insertion (TAVI) is proposed …

Stents for transcatheter aortic valve replacement
… life once the disease becomes symptomatic. Transcatheter aortic valve replacement (TAVR) has revolutionised the treatment of age-related degenerative aortic valve disease, but is currently not suitable for the majority of RHD sufferers due to the rapid degeneration of flexible leaflet valves …

Fluid Dynamics Characterization of Transcatheter Aortic Valves
… due to population ageing and health lifestyle. Transcatheter aortic valve replacement (TAVR) was introduced as a minimal invasive treatment of severe aortic stenosis. Even though surgical aortic valve replacement (SAVR) is considered the golden standard treatment for severe aortic stenosis …

Transcatheter Mitral Valve Replacement: Structural and Hemodynamic Analysis
<p>Transcatheter mitral valve replacement (TMVR) is being developed to become a substitute therapy for surgery in prohibitive or high surgical risk patients to treat severe mitral regurgitation. A limited number of TMVR systems are under clinical evaluation. However, transcatheter mitral valve …

Fluid Dynamics Assessment of Transcatheter Aortic Valve Replacement Performance
Transcatheter aortic valve replacement (TAVR) an alternative therapy to standardized surgical aortic valve replacement (SAVR) in the treatment of severe symptomatic aortic stenosis has evolved greatly in the last decade based on results from successful clinical trials. These trials revealed …
-
Transcatheter Aortic Valve Implantation: Risk Assessment and Clinical Outcome
Abstract Background: Transcatheter aortic valve implantation (TAVI) has emerged as a treatment for patients with aortic stenosis (AS) and high surgical risk. To date, reports of short- and mid-term survival have been favourable. The aim of this thesis was to evaluate early safety, risk assessment …

Hybrid Electrospun Transcatheter Aortic Heart Valves for Tissue Engineering Applications
… after various periods of hydrolytic degradation. Transcatheter aortic heart valves (23 mm) with DegraPol®, Pellethane®, and hybrid leaflets respectively, were fabricated by means of bonding and suturing into balloon expandable transcatheter stents and tested in vitro at left heart conditions to …

DESIGN & DEVELOPMENT OF HETEROTOPIC TRANSCATHETER TRICUSPID VALVES TO AMELIORATE TRICUSPID REGURGITATION
… conventional open heart surgery. The advent of transcatheter technology gives them a new treatment alternative. However, so far, there has been no commercially available transcatheter tricuspid valve. This may be because of the complex tricuspid valve anatomy and the lack of an anchorage zone. …

Transcatheter Arterial Embolization of Prostate in Hormone Induced Canine Prostate Hyperplasia
… unlike the non-embolized dogs. CONCLUSION: Transcatheter arterial embolization is effective and safe to reduce the prostate volume without serious complications in hormone induced canine prostate hyperplasia.

Albumin Is Predictive of 1-Year Mortality After Transcatheter Aortic Valve Replacement
The general metadata -- e.g., title, author, abstract, subject headings, etc. -- is publicly available, but access to the submitted files is restricted to UT Southwestern campus access and/or authorized UT Southwestern users.

Improving Preadmission Testing Nurses' Knowledge of Aortic Stenosis and Transcatheter Aortic Valve Replacement
… of severe/critical aortic stenosis (AS), transcatheter aortic valve replacement (TAVR) procedure and patient selection, and satisfaction with knowledge by 10%. Rapid growth of the TAVR program has contributed to a gap in nursing knowledge leading to inconsistent patient care and education. …

Design and development of an electrospun polymeric transcatheter heart valve for tissue engineering
… and the ground-breaking introduction of transcatheter valve technologies, current solutions offer suboptimal therapy as they either require lifelong anticoagulation or have limited durability. The ideal replacement valve should mimic the functionality of its native counterpart, comprise …

Comparison of patient outcome for aortic valve replacement verses transcatheter aortic valve replacement
… intervention until 2002 with the advent of transcatheter aortic valve replacement (TAVR). TAVR has since been approved by the Food and Drug Administration (FDA) for use in patients who are not candidates for AVR or who are at high risk for AVR. The initial studies of TAVR showed an elevated …

The Surgical Management of Severe Aortic Stenosis In the Era of Transcatheter Aortic Valve Replacement
Transcatheter aortic valve replacement (TAVR) has emerged as a treatment option for severe and symptomatic aortic stenosis across the spectrum of surgical risk and has potentially transformed the surgical management of aortic stenosis. The objectives of this dissertation were: (1) To determine if …

Predicting Transcatheter Aortic Valve Leaflet Thrombosis Risk Using Pre-Procedural Computed Tomography Angiogram and Computational Modeling
… valve either via open-heart surgery or transcatheter aortic valve replacement (TAVR), a less invasive procedure that has shown similar long-term outcomes as surgery. However, there have been reported instances of complications occurring post-TAVR, one of the most common ones being …

Development of a patient-specific finite element model of the transcatheter aortic valve implantation (TAVI) procedure
Transcatheter Aortic Valve Implantation (TAVI) is a procedure developed for replacing the defective aortic valve of a patient as an alternative to open heart Surgical Aortic Valve Replacement (SAVR). In the TAVI procedure a prosthetic valve, which is assembled on to a stent, is crimped and …

The design and prototyping of a Transcatheter Aortic Valve Implantation training system specific for aortic valve regurgitation.
… of a bioprosthetic or mechanical heart valve. Transcatheter Aortic Valve Implantation (TAVI) has become a common surgical procedure to replace defective aortic valves. The balloon-expandable (BE) transapical TAVI technique involves, a replacement valve crimped onto an inflatable medical balloon …
