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 …

DEVELOPMENT AND VALIDATION OF B2AND2SV2ASC SCORE FOR PREDICTING RISK OF STROKE ONE YEAR AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT
… after transcatheter aortic valve replacement (TAVR) is a significant cause of morbidity and mortality. It increases the risk of mortality within one year of TAVR threefold. It is also associated with significant disability and increased health care costs. A validated risk prediction tool for …

Predicting Transcatheter Aortic Valve Leaflet Thrombosis Risk Using Pre-Procedural Computed Tomography Angiogram and Computational Modeling
… 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 leaflet thrombosis (LT). LT is characterized …

Thirty-Day Readmissions after Early versus Delayed Discharge after Uncomplicated Transcatheter Aortic Valve Replacement: Insights from the Nationwide Readmissions Database
… after transcatheter aortic valve replacement (TAVR) has generally shown to be safe; however, studies have been limited to single centers or trial populations, making their generalizability unclear. This study sought to examine the rate of rehospitalization after early vs. late discharge …

Improving Preadmission Testing Nurses' Knowledge of Aortic Stenosis and Transcatheter Aortic Valve Replacement
… (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. An educational program was developed …

Comparison of patient outcome for aortic valve replacement verses transcatheter aortic valve replacement
… 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 risk of stroke in those undergoing …

Fluid Dynamics Characterization of Transcatheter Aortic Valves
… 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 patients, TAVR showed equivalent or even …

Fluid Flow Characterization and In Silico Validation in a Rapid Prototyped Aortic Arch Model
<p>Transcatheter aortic heart valve replacement (TAVR) is a procedure to replace a failing aortic valve and is becoming the new standard of care for patients that are not candidates for open-heart surgery [2]. However, this minimally invasive technique has shown to cause ischemic brain lesions, or …

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 …

Paravalvular sealing pf percutaneous heart valves
… after transcatheter aortic valve replacements (TAVR) can lead to adverse clinical consequences and has been shown to correlate to an increased late mortality and morbidity. Quantification, graduation and testing for PVR has proven challenging and a standardized method for pre-clinical testing is …

A Journey Through The Thoracic Aorta: From Root To Arch
… (Chapter 4) models; and 2. Comparing SAVR & TAVR in relation to (a) clinical outcomes (Chapter 5) and (b) patient-related outcomes (Chapter 6). Methods: Chapter 2, focused on histological analysis of aneurysmal aortas, and involved laboratory preparation of human aneurysmal and non-aneurysmal …

Optimizing interventions for the treatment of vascular flow disruptions
… such as transcatheter aortic valve replacements (TAVR), have significantly improved quality of life and life expectancy. However, these emerging technologies involve unique delivery modes and anchoring mechanisms that require the prosthesis to intimately interact with the aortic wall. As aortic …

Stents for transcatheter aortic valve replacement
… 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 in younger patients, contraindications …
