  • dilatation
  • 12-17 In these studies, leaflet tethering by the displaced PMs due to regional or global LV dysfunction has been suggested as a main mechanism of functional MR. However, the geometry of the mitral apparatus accompanied by regional or global LV dilatation has not been clarified differentially. (ahajournals.org)
  • Regurgitation may be due to a structural change of components of the tricuspid valve apparatus, a lesion can be primary (intrinsic abnormality) or secondary (right ventricular dilatation). (wikipedia.org)
  • This dilatation of the left ventricle can be due to any cause of dilated cardiomyopathy including aortic insufficiency, nonischemic dilated cardiomyopathy, and Noncompaction cardiomyopathy. (wikipedia.org)
  • Functional
  • Conclusions- The pattern of MV deformation from the medial to the lateral side was asymmetrical in ICM-MR, whereas it was symmetrical in DCM-MR. RT3DE is a helpful tool for differentiating the geometry of the mitral apparatus between these 2 different types of functional mitral regurgitation. (ahajournals.org)
  • apparatus
  • The invention relates to heart valve repair and particularly to annuloplasty apparatus and methods. (google.es)
  • 6-11 With recent advances in 3D imaging techniques, geometric changes of the mitral apparatus accompanied by distortion of the LV chamber from which the PMs arise have been explored. (ahajournals.org)

  • The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. (wikipedia.org)
  • The subvalvular apparatus has no effect on the opening and closure of the valves, however, which is caused entirely by the pressure gradient across the valve. (wikipedia.org)
  • Dysfunction of any of these portions of the mitral valve apparatus can cause regurgitation. (wikipedia.org)
  • percutaneous
  • In patients who may not be appropriate candidates for traditional or minimally invasive valve surgeries, percutaneous options allow a replacement valve to be delivered and placed through a catheter that is threaded through blood vessels rather than performing open heart surgery. (ucsd.edu)
  • The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty. (wikipedia.org)
  • The resultant tricuspid regurgitation from percutaneous treatment is better tolerated than the insufficiency occurring during mitral valvuloplasty. (wikipedia.org)
  • myocardium
  • The present study, therefore, assessed the correlation between the LA volume and LV filling pressure in patients with severe mitral regurgitation (MR). Because the LA pressure increases to maintain adequate LV diastolic filling, increased atrial wall tension tends to dilate the chamber and stretch the atrial myocardium. (clinicaltrials.gov)
  • During left ventricular diastole, after the pressure drops in the left ventricle due to relaxation of the ventricular myocardium, the mitral valve opens, and blood travels from the left atrium to the left ventricle. (wikipedia.org)
  • This early filling phase is due to active relaxation of the ventricular myocardium, causing a pressure gradient that allows a rapid flow of blood from the left atrium, across the mitral valve. (wikipedia.org)

(wikipedia.org)
  • blood flows
  • The valves of the heart wouldn't close properly resulting in mitral regurgitation, where blood flows backward forcing the heart to work harder to pump blood throughout her body. (prweb.com)
  • In normal conditions, blood flows through an open mitral valve during diastole with contraction of the left atrium, and the mitral valve closes during systole with contraction of the left ventricle. (wikipedia.org)
  • Heart murmurs are heart sounds produced when blood flows across one of the heart valves that are loud enough to be heard with a stethoscope. (wikipedia.org)
  • Murmurs may also be the result of various problems, such as narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the heart. (wikipedia.org)
  • In ventricular systole under MR, regurgitant blood flows backwards/retrograde back and forth through a diseased and leaking mitral valve. (wikipedia.org)
  • severe
  • The study is designed to assess 1) the relationship between LV filling pressure and LA distensibility, and 2) the power of left atrial distensibility to predict the prognosis, including operation mortality, the rate of post-operation atrial fibrillation, and late heart failure event in patients with severe mitral regurgitation. (clinicaltrials.gov)
  • in many instances replacement will be the only realistic option because of severe destruction of the valve. (wikipedia.org)
  • leaflet
  • In the last two years, the development of transesophageal imaging with 3D capability has allowed a better visualization of mitral leaflet pathology. (clinicaltrials.gov)
  • Annular and subvalvular geometry both affect leaflet curvature, and should be considered during mitral repair. (biomedsearch.com)
  • Microscopically, there is no evidence of an annular structure anteriorly, where the mitral valve leaflet is contiguous with the posterior aortic root. (wikipedia.org)

  • Our Valve Clinic treats all types of valve disease, including referrals of the most challenging cases. (ucsd.edu)
  • Valve disease can be treated with medication, but depending on the severity of the case, valve repair surgery or replacement surgery (insertion of an artificial heart valve) is often necessary. (ucsd.edu)
  • Although traditional open heart surgery is still the standard for many patients, in certain patients with isolated valve disease, a minimally invasive approach can be used. (ucsd.edu)

  • For patients with the most common type of mitral valve disease, termed "degenerative" or "myxomatous" mitral valve disease, repair rates are very high and long term durability is excellent. (wikipedia.org)
  • Valve failure or dysfunction can result in diminished heart functionality, though the particular consequences are dependent on the type and severity of valvular disease. (wikipedia.org)
  • Irrespective of disease process, alterations to the valve occur that produce one or a combination of these conditions. (wikipedia.org)
  • Aortic and mitral valve disease are termed left heart diseases. (wikipedia.org)
  • Diseases of these valves are more prevalent than disease of the pulmonary or tricuspid valve due to the higher pressures the left heart experiences. (wikipedia.org)

  • This amount of blood is known as the end diastolic volume (EDV), and the mitral valve closes at the end of atrial contraction to prevent a reversal of blood flow. (wikipedia.org)
