Artificial muscle technology applied towards treating ischemic mitral regurgitation caused by left ventricular remodeling
Ischemic Mitral Regurgitation (MR) affects a large portion of patients suffering from ischemic heart disease. Significant MR develops in one quarter to one third of patients who suffer from ischemic heart disease and doubles their late mortality rate after a myocardial infarction or …

Assisted auscultation : creation and visualization of high dimensional feature spaces for the detection of mitral regurgitation
… built to aid medical practitioners in diagnosing Mitral Regurgitation (MR) based on heart sounds. Our work builds on the "prototypical beat" introduced by Syed in [17] to extract two different feature sets characterizing systolic acoustic activity. One feature set is derived from current medical …

Surgery for Degenerative Mitral Valve Disease:Earlier Intervention, New Procedures, and Better Outcomes
… of surgical techniques for degenerative mitral valve (MV) disease, and effects of these changes on surgical morbidity and mortality and hospital stay.Methods: From 1985 to 2010, 7,982 patients underwent surgery for degenerative mitral regurgitation; 5,045 had isolated MV procedures, …

Valvular heart disease: novel epidemiological and imaging studies
… of patients with clinically significant mitral regurgitation. The prevalence of undiagnosed valvular heart disease in those aged 65 and over is examined in Chapters 2 and 3. Chapter 2 outlines a population-based screening study for VHD in primary care in Oxfordshire, which the author …

Balloon mitral valvuloplasty at Groote Schuur Hospital : results, complications and short-term follow-up
Balloon dilatation of the stenosed mitral valve, in an attempt to relieve symptoms, was developed to replace the surgical procedure of closed mitral valvotomy. This procedure, whereby a balloon tipped catheter is introduced from the femoral vein and directed across the mitral valve after an atrial …

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 …

Echocardiographic Investigation of Canine Myxomatous Mitral Valvular Disease
… the echocardiographic anatomy of the canine mitral valve in healthy dogs and those affected by myxomatous mitral valve disease (MMVD), and to compare the level of agreement between two methods of assessment of left atrial size in identification of left atrial enlargement in dogs with MMVD. …

Development of a high-fidelity biorobotic cardiovascular in vitro simulator
… We then mimic a pathological condition (acute mitral regurgitation) with the heart model and demonstrate various interventions (such as surgical repair, replacement and minimally invasive repair procedure) with collaborating cardiac surgeons. Overall, the biorobotic cardiovascular in vitro …

Nuove acquisizioni in termini di insufficienza mitralica: complicanze tromboemboliche dopo chirurgia della valvola mitrale: incidenza, predittori e implicazioni cliniche
… to define in patients undergoing surgery for mitral regurgitation (MR) the risk of thrombo-embolic complications, particularly ischemic stroke (IS) compared to that in the general population. Background: MR is frequent, occurs mostly in the elderly and guidelines recommend surgery in …

Effect of ivabradine, a novel I<sub>f</sub> current inhibitor, on dynamic obstruction of the left ventricular outflow tract in cats with preclinical hypertrophic cardiomyopathy: a single-dose study
… of the left ventricular outflow tract and mitral regurgitation secondary to hypertrophy of the left ventricle and systolic anterior motion (SAM) of the mitral valve. This leads to an increase in left ventricular systolic pressure, and thus wall stress, that may ultimately lead to …

Neurohormonal and inflammatory markers in valvular heart disease
… including aortic stenosis (n=74), aortic regurgitation (n=40) and mitral regurgitation (n=49) underwent independent assessment of symptoms, transthoracic echocardiography and measurement of plasma levels of ANP, BNP and N-BNP. Natriuretic peptide levels were significantly higher in …

The development and course of heart failure after a myocardial infarction
… ACE inhibitors), a dilated atrium, substantial mitral regurgitation and atrial fibrillation (and therefore treatment with warfarin and digoxin) (p=0.0001). Thirty six patients died during follow-up; 28 (42%) with an NT-proBNP >50pmol/L (423pg/ml) (77% of all deaths). ROC curves suggested that …
