Comparison of patient outcome for aortic valve replacement verses transcatheter aortic valve replacement
Aortic stenosis or narrowing of the aortic valve is the most common cause for surgical valvular replacement in the United States. The disease of aortic stenosis has a long asymptomatic latency period followed by a quickly progressing symptomatic phase. Symptoms of the disease include dyspnea, …

Stents for transcatheter aortic valve replacement
… heart disease (RHD) is the leading cause of aortic valve disease in the world. Surgery to repair or replace the diseased valves is the only means to save a patient's life once the disease becomes symptomatic. Transcatheter aortic valve replacement (TAVR) has revolutionised the treatment of …

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 …

Improving Preadmission Testing Nurses' Knowledge of Aortic Stenosis and Transcatheter Aortic Valve Replacement
… (PAT) nurses’ knowledge 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 …

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 …

Aortic Valve Replacement: The Influence of Prosthesis-Patient Mismatch for Left Ventricular Remodeling, Cardiac Function and Survival
The best valve substitute for aortic valve replacement (AVR) in terms of hemodynamic performance, durability, incidence of complications, and survival remains the subject of much debate. It has been suggested that valve performance is influenced by the potentially modifiable variable …

DEVELOPMENT AND VALIDATION OF B2AND2SV2ASC SCORE FOR PREDICTING RISK OF STROKE ONE YEAR AFTER TRANSCATHETER AORTIC VALVE REPLACEMENT
INTRODUCTION Stroke 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 …

Thirty-Day Readmissions after Early versus Delayed Discharge after Uncomplicated Transcatheter Aortic Valve Replacement: Insights from the Nationwide Readmissions Database
Early discharge 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 …

Prognosis and Prognostic Factors in Aortic Valve Replacement for Aortic Stenosis // Прогноза и прогностични фактори при аортно клапно протезиране по повод на аортна стеноза
Калцификационната аортна клапна стеноза е хронично заболяване с прогресиращ ход. В крайния стадий на болестта се изявяват клинично белезите и симптомите на сърдечната недостатъчност и настъпва летален изход. Калцификационната аортна стеноза заема първо място, като причина за хирургично аортно …

Zweidimensionale Strain-Echokardiographie zur Analyse der regionalen linksventrikulären Funktion bei Aortenklappenvitien vor und nach operativem Aortenklappenersatz
In 53 patients scheduled for aortic valve replacement (22 with aortic stenosis (AS), 18 with aortic insufficiency (AI), 13 with aortic stenosis and insufficiency serial echocardiographic studies were performed pre- and postoperatively (within 7 days and at 6 months). Basal, mid and apical …

Fluid Dynamics Characterization of Transcatheter Aortic Valves
<p>Aortic stenosis due to degenerative calcific aortic valvular disease is the most reason for aortic valve replacement in developed countries. Aortic stenosis affects up to 7% of the world population, and current clinical data indicate that the number of the affected people could be triple by …

A sequential evaluation of left ventricular function in asymptomatic and symptomatic patients with chronic severe aortic regurgitation
The optimal timing of valve replacement surgery in chronic severe aortic regurgitation (AR) has remained a major clinical problem in the management of these patients. Although the onset of symptoms is the generally accepted indication for aortic valve replacement (AVR), the unpredictable …

A Journey Through The Thoracic Aorta: From Root To Arch
… and pathological outcomes of disease of the aortic valve and the ascending aorta, including the aortic root. Purpose: The aortic valve and proximal aorta are the anatomical origin of the systemic circulation and pathology in this area can be catastrophic. Despite this, there is limited …

Predicting Transcatheter Aortic Valve Leaflet Thrombosis Risk Using Pre-Procedural Computed Tomography Angiogram and Computational Modeling
Aortic stenosis (AS) is a disease that affects nearly 3% of adults above the age of 65 and is characterized by narrowing of the aortic heart valve due to calcium buildup. It restricts blood flow from the heart and, if left untreated, can lead to irreversible damage to the left ventricle wall and …

Design and implementation of an apparatus for hydrodynamic and fatigue testing of prosthetic aortic valves
Aortic valve replacement in humans may be needed due to pathology leading to valve stenosis and regurgitation. Replacement is by either mechanical or soft tissue prosthetic valves. Before new valves are medically approved and introduced into the market they are required to undergo rigorous testing …
