AORTIC STIFFNESS MODIFICATIONS AFTER ENDOVASCULAR AORTIC REPAIR
Background: Endovascular aortic repair (EVAR and TEVAR) has transformed the management of aortic aneurysms and dissections through its minimally invasive approach and favorable short-term outcomes. However, concerns regarding the long-term cardiovascular implications of endograft implantation have …

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 …

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, …

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 …

Risk Factors in Abdominal Aortic Aneurysm
The mortality rate of ruptured abdominal aortic aneurysm (AAA) has been reported to be as high as 85%. Evidence suggests that ultrasound screening reduces overall and AAA-related mortality. The aim of this study was to identify and document risk factors for AAA from the largest Welsh cohort …

Molecular genetics of abdominal aortic aneurysm
Abdominal aortic aneurysm (AAA) is a common disorder and a major cause of death. Pathological processes involved in AAA formation include inflammation, proteolysis, angiogenesis and apoptosis. It has also a strong familial predisposition with linkage studies identifying chromosomes 19q13 and 4q31 …

Imaging microcalcium in thoracic aortic disease
… complications occur, such as stroke or aortic dissection. Current management strategies focus on preventative interventions which can include high-risk surgery. However, identifying those who are most appropriate for such interventions is challenging. Deposition of calcium crystals …

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 …

The design and prototyping of a Transcatheter Aortic Valve Implantation training system specific for aortic valve regurgitation.
Aortic regurgitation (AR) caused by rheumatic heart disease is a significant cause of mortality in developing countries. The replacement of the regurgitant aortic valve was historically performed by surgical insertion of a bioprosthetic or mechanical heart valve. Transcatheter Aortic Valve …

Abdominal Aortic Aneurysm – Different Aspects on Screening
Abstract Abdominal aortic aneurysm (AAA) is a hideous life threatening disease that most often is asymptomatic until it ruptures. Ruptured abdominal aortic aneurysm (rAAA) is a painful and serious predicament with a mortality of 80-90%. Half of the patients die before arriving to hospital, leaving …

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 …

Predicting Aortic Stenosis Severity using Deep Learning
… cause of death globally. This thesis focuses on aortic stenosis, one of the most common and severe valve diseases. The evaluation of patients with suspected aortic stenosis includes echocardiography - an ultrasound based procedure that is used to visualize and evaluate the aortic valve. …

Outcomes after thoracic endovascular aortic repair (TEVAR) in patients with traumatic thoracic aortic injuries (TTAI) - a single center retrospective review
… Blunt and penetrating traumatic thoracic aortic injuries constitute surgical emergencies that are attended with high mortality rates. Most patients do not survive long enough, post injury, to reach a hospital. On-site mortality rates may approach approximately 85%. Two main treatment …

Prediction of outcome after abdominal aortic aneurysm rupture
… for outcome prediction after abdominal aortic aneurysm (AAA) rupture and to design and validate a novel risk scoring instrument. It also aims to examine the utility of novel predictive variables. Finally, it examines the functional outcomes achieved by survivors of aneurysm rupture.
