• Carcinoid
  • Additionally, insufficiency may be the result of carcinoid syndrome, inflammatory processes such a rheumatoid disease or endocarditis, or congenital malformations. (wikipedia.org)
  • Certain carcinoid syndromes can affect the tricuspid valve by producing fibrosis due to serotonin production by those tumors. (wikipedia.org)
  • prosthetic
  • The mitral valve annulus is reinforced internally by a variety of prosthetic rings (Duran Ring, Medtronic Inc) or bands (Cosgrove-Edwards Annuloplasty Band, Edwards Lifesciences Inc). The present paradigm of mitral valve reconstruction is therefore repair from inside the heart, with the annulus being buttressed or reinforced by the implantation of a prosthetic-band or ring. (google.es)
  • In terms of treatment for tricuspid insufficiency prosthetic valve substitutes can be used, though artificial prostheses may cause thrombo‚Äźembolic phenomena(bioprostheses may have a degeneration problem). (wikipedia.org)
  • dilatation
  • The present invention relates to devices and methods for treating dilatation of the valves at the base of the heart by external stabilization of the base of the heart, which subtend the atrio-ventricular valves of the heart. (google.es)
  • In some instances, depending on the cause, the dilatation may be localized to one portion of the base of the heart (e.g., mitral insufficiency as a consequence of a heart attack affecting the inferior and basal wall of the left ventricle of the heart), thereby affecting the valve in that region. (google.es)
  • Other conditions exist where the mitral valve structure is abnormal, predisposing to leakage and progressive dilatation of the valve annulus (area of valve attachment to the heart). (google.es)
  • 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)
  • chordae
  • They are anchored to the walls of the ventricles by chordae tendineae, which prevent the valves from inverting. (wikipedia.org)
  • The chordae tendineae act a bit like the strings on a parachute, and allow the leaflets of the valve to balloon up into the atria slightly, but not so much as to evert the cusp edges and allow back flow of blood. (wikipedia.org)
  • velocity
  • These patients had significant increased tricuspid valve Aa velocity and E/Ea ratio and had significant difference with normal references of age during follow up period. (tums.pub)
  • blood flows
  • 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)
  • surgical
  • 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)
  • reversal
  • The S1 sound results from reverberation within the blood associated with the sudden block of flow reversal by the valves. (wikipedia.org)
