• Echocardiographic evaluation before the procedure is of paramount importance in defining the complex morphology of the valve and in detecting target leaflet lesion. (springer.com)
  • In the last two years, the development of transesophageal imaging with 3D capability has allowed a better visualization of mitral leaflet pathology. (clinicaltrials.gov)

  • Effect of percutaneous mitral repair with the MitraClip device on mitral valve area and gradient. (springer.com)
  • This disorder can be due to backward movement of the valve (prolapsing), thickening of the valve, gradual (chronic) degeneration of the valve, bacterial infection of the valve, narrowing of the opening in the valve or dysfunction of the muscles or chords controlling the valve.

  • Tissue valves (human tissue from a cadaver) lasts about 10 to 15 years. (brainscape.com)
  • Finally, artificial tissue valves will wear out - on average lasting between 10 and 15 years, requiring further surgery at an advanced age. (wikipedia.org)
  • Percutaneous repair or surgery for mitral regurgitation. (springer.com)
  • Procedures on the mitral valve usually require a median sternotomy, but advances in non-invasive methods (such as keyhole surgery) allow surgery without a sternotomy (and resulting pain and scar). (wikipedia.org)
  • In 1923 Dr. Elliott Cutler of the Peter Bent Brigham Hospital performed the world's first successful heart valve surgery - a mitral valve repair. (wikipedia.org)
  • The function of the four heart valves is to direct flow of blood through the heart. (beaumont.org)

  • Mitral regurgitation, or leaking of the mitral heart valve, is usually studied and assessed with an ultrasound test called a two-dimensional (2D) echocardiogram. (clinicaltrials.gov)
  • While this test has proved very useful, technological improvements have helped researchers develop ways to study the heart valves using imaging with three-dimensional (3D) capabilities. (clinicaltrials.gov)
  • Dermatan sulfate is a glycosaminoglycan (formerly called a mucopolysaccharide) found mostly in skin, but also in blood vessels, heart valves, tendons, and lungs. (wikipedia.org)
  • The mitral valve is the "inflow valve" for the left side of the heart. (wikipedia.org)
  • The development of the heart-lung machine in the 1950s paved the way for replacement of the mitral valve with an artificial valve in the 1960s. (wikipedia.org)
  • The traditional surgical approach to a mitral valve repair is a full or partial sternotomy, in which the surgeon cuts through the breastbone at the center of the chest to access the heart. (wikipedia.org)
  • In the past two decades, some surgeons have embraced surgical techniques to repair the damaged native valve, rather than replace it. (wikipedia.org)
  • Infection of the valve can occur, which is dangerous and difficult to treat. (wikipedia.org)
  • In this chapter we describe the normal mitral valve anatomy as displayed by 3D TEE, the 3D TEE pre-procedural characterization of valve morphology and the growing role of RT TEE in any individual steps of this complex procedure. (springer.com)
  • Color Doppler 3D studies have shown that 2D methods generally underestimate mitral regurgitant volume. (clinicaltrials.gov)
