• surgical
  • An annuloplasty system for repairing a valve in a patient's heart comprises a surgical implant including a member having first and second end portions. (google.es)
  • Its presence increases long-term risk and mortality even after surgical valve repair. (ahajournals.org)
  • As a result the majority of mitral valve disorders can be repaired by modern surgical techniques in experienced hands. (maimonidesmed.org)
  • Generally, surgical treatment of tricuspid regurgitation is not indicated when it has arisen as a result of right ventricular dilatation. (wikipedia.org)
  • Leaking valves can be corrected by mitral valve annuloplasty, a common surgical procedure that aims at restoring proper leaflet adjustment. (wikipedia.org)
  • For decades after, mitral valve replacement was the only surgical option for patients with a severely diseased mitral valve. (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)
  • 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)
  • Treatment of damaged valves may involve medication alone, but often involves surgical valve repair (valvuloplasty) or replacement (insertion of an artificial heart valve). (wikipedia.org)
  • dilatation
  • Specific to these diseases, the mitral valve is normal, but the leaflet edges do not meet creating a large leak, because its supporting structures are pulled away and outward by the dilatation of the heart. (maimonidesmed.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)
  • Much more common than a congenital abnormality of the valve, however, is right ventricular dilatation of any cause. (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)
  • median sternotomy
  • 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)
  • 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)
  • While the techniques can differ, the principles of restoring adequate leaflet coaptation in the annular plane, and thus competency of the valve, remain the same. (maimonidesmed.org)
  • Microscopically, there is no evidence of an annular structure anteriorly, where the mitral valve leaflet is contiguous with the posterior aortic root. (wikipedia.org)
  • degenerative
  • As assessed using three-dimensional (3D) magnetic resonance imaging (MRI), what changes in left ventricular (LV) end-systolic dimension and volume occur among patients with isolated degenerative mitral regurgitation (MR)? (acc.org)
  • Because the results of valve repair done by experienced surgeons in experienced centers are so good and so advantageous over replacement, repair has become the standard of care for degenerative mitral valve disease. (maimonidesmed.org)
  • More often the mitral valve becomes abnormal with age (degenerative) or as a result of rheumatic fever. (wikipedia.org)
  • 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)
  • 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)
  • Inclusion criteria were (1) structurally normal MV, (2) technically adequate color flow Doppler image for proximal isovelocity surface area (PISA), (3) technically adequate RT3DE image of the LV chamber and the mitral apparatus to allow analysis of 3D geometry, and (4) normal sinus rhythm. (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)
  • myocardium
  • 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)
  • Pediatric cardiology - Heart - Chordae tendinae - Right atrium - Right ventricle - Tricuspid valve - Left atrium - Left ventricle - Mitral valve - Endocardium - Myocardium - Pericardial cavity - Transverse pericardial sinus - Pericardium - The cardiac physical exam focuses on portions of the physical exam that elucidate information about diseases and disorders outlined below. (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)
  • patients
  • Researchers are interested in testing these new techniques to determine their usefulness for patients with mitral regurgitation. (clinicaltrials.gov)
  • There is no incision, the recovery time is less and patients stay in the hospital one or two days and have very good results,' said Dr. Satpathy, who prior to coming to Baptist Heart Specialists was director of the Valve Clinic and Structural Heart Program at CHI Alegent Creighton Heart and Vascular Institute in Omaha, Neb. (prweb.com)
  • Thirty-five patients underwent mitral valve repair per current guideline recommendations. (acc.org)
  • While today, a well performed mitral valve repair is viewed as superior, particularly for valve regurgitation, replacement is still a viable option for some patients. (maimonidesmed.org)
  • Artificial valves are extremely durable, but they do require patients to take anticoagulant (anti-clotting) medication every day to prevent stroke. (maimonidesmed.org)
  • Patients whose valves have been repaired have a better survival over the next 10 to 20 years compared to patients who received a prosthetic valve. (maimonidesmed.org)
  • For patients who have no symptoms and in whom there has been no change in heart function, surgery is recommended if the diagnostic echocardiogram indicates a high expectation that the valve is indeed repairable. (maimonidesmed.org)
  • Quadricuspid aortic valves are very rare cardiac valvular anomalies with a prevalence of 0.013% to 0.043% of cardiac cases and a prevalence of 1 in 6000 patients that undertake aortic valve surgery. (wikipedia.org)
  • Mid-term results in patients having tricuspidization of the quadricuspid aortic valve. (wikipedia.org)
  • Patients with mechanical heart valves are required to take blood thinners for the rest of their lives, which presents a risk of bleeding complications. (wikipedia.org)
  • Patients with mechanical heart valves who use warfarin for anticoagulation have to be on long-term anticoagulation therapy. (wikipedia.org)
  • There has been great debate about timing of surgery in patients with asymptomatic mitral valve regurgitation. (wikipedia.org)
