Closed mitral valvotomy in pregnancy
… cardiac disease. In the Third World rheumatic mitral valve disease remains a most important condition during pregnancy. It is currently rarely seen in Europe and the United States. Mitral stenosis is the most commonly encountered rheumatic heart lesion that complicates pregnancy. The normal …

The longitudinal outcome of canine myxomatous mitral valve disease in dogs: The LOOK Mitral study
Myxomatous mitral valve disease (MMVD) is the most common heart disease in dogs. However, prospectively acquired data describing the natural history and prognostic factors in a large population of dogs affected by this disease are sparse. Thus, the Longitudinal Outcome of canine (K9) myxomatous …

The effects of mitral annular dynamics, and the laceration of the anterior leaflet with transcatheter mitral valve replacements
High-risk patients in need of a mitral valve replacement created a demand for percutaneous MV interventions. With no dedicated devices currently on the market, clinicians have resorted to placing transcatheter aortic valves (TAV) into mitral annular calcification (Valve-in-MAC), failing mitral …

Mitral insufficiency due to ruptured chordae tendineae
<p>The clinical features in six patients with mitral insufficiency due to chordae tendineae have been.</p><p> The patients in whom the etiology was not known did not become symptomatic till they were past 40, although a murmur had been present for several years. Pulmonary edema or paroxysmal …

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. …

Multimodal treatment of women with mitral valve prolapse syndrome
Mitral valve prolapse is the most commonly occurring cardiac condition. It is a benign condition which affects as many as 10% of the population. Some patients have symptomatic mitral valve prolapse. This condition is referred to as mitral valve prolapse syndrome. Symptoms include: chest pain, …

Optimisation of Surgical Timing in Rheumatic Mitral Valve Disease
… the left atrium in the management of rheumatic mitral valve disease. It finds that left atrial ejection fraction is the strongest and most reliable predictor for developing a guideline indication for valve intervention in the subsequent two-years. Finally, the insights gained in current …

Automated auscultation : using acoustic features to diagnose mitral valve prolapse
… cardiac disorders, the most common of which is Mitral Valve Prolapse (MVP). Yet, the practice of auscultation is highly fallible with reports of more than 80% of MVP referrals to cardiologists being unnecessary. The overall goal is to develop an inexpensive, easy-to-deploy software application …

Advanced Echocardiographic Imaging In Dogs With Myxomatous Mitral Valve Disease
Myxomatous mitral valve degeneration (MMVD) is the most common canine cardiac disease. In the studies presented in this dissertation, we used advanced echocardiographic techniques to elucidate several aspects of MMVD in dogs. Our hypothesis was that the mitral valve (MV) morphology could have a …

Dynamic simulation of heart mitral valve with transversely isotropic material model
… element setting, the material behavior of heart mitral valve leaflet tissue. First, a mixed pressure-displacement formulation is used to implement the constitutive material behavior with general 3D elements. Second, a shell is formulated that incorporates the 3D material behavior by use of a …

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, …

Insuficiencia mitral funcional: evolución clínica, estructural y funcional tras el clipaje de velos
La insuficiencia mitral es la segunda valvulopatía más frecuente en Europa, con un aumento de su incidencia en los últimos años debido al envejecimiento de la población. Durante muchos tiempo, el tratamiento médico era la única opción para aquellos pacientes con insuficiencia mitral funcional con …

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 …

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 …

Accuracy of Noninvasively Determined Pulmonary Artery Pressure in Dogs With Myxomatous Mitral Valve Disease
Development of pulmonary hypertension is an independent predictor of poor outcome in dogs affected by myxomatous valvular degeneration (MMVD). Systolic pulmonary arterial pressure is routinely estimated by Doppler echocardiography applying the simplified Bernoulli equation to the velocity of …
