• leaflet
  • A portion of the AV valves originates from the endocardial cushions, and their improper fusion results in anterior and posterior components to the mitral valve leaflet. (medscape.com)
  • Without the third leaflet, the valve may be stiff (unable to open or close properly) or leaky (not able close tightly). (medicinenet.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)
  • Leaking valves can be corrected by mitral valve annuloplasty, a common surgical procedure that aims at restoring proper leaflet adjustment. (wikipedia.org)

  • anticoagulation
  • Mechanical valves last longer but they do require anticoagulation. (brainscape.com)
  • BestBets: Is short-term anticoagulation necessary after mitral valve repair? (bestbets.org)

  • Compared to the results of valve replacement there will be a minimal tendency towards clot formation after aortic valve repair, and anticoagulation is commonly not necessary, thus minimizing the possibility of bleeding complications. (wikipedia.org)
  • Diastolic
  • 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)
  • A mild diastolic murmur can be heard during auscultation caused by the blood flow through the stenotic valve. (wikipedia.org)
  • closure
  • 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)
  • The entire Delrin structure was covered with seamless Dacron velour and at a later stage, the margins of the scalloped edges were covered with a thin layer of pericardium in an attempt to prevent or reduce the abrasion of the leaflets when in contact with this margin during valve closure. (wikipedia.org)
  • commonly
  • These examples are not considered infectious diseases because they do not satisfy Koch's postulates - for example Staphylococcus intermedius, a commonly isolated bacteria from skin infections in dogs, would not cause pyoderma when introduced to a healthy dog. (wikipedia.org)
  • acute
  • It is the most prominent symptom in Kawasaki disease, is a characteristic sign of the acute phase of the disease, is normally high (above 39-40 °C), is remittent, and is followed by extreme irritability. (wikipedia.org)
  • It usually begins shortly after the onset of fever during the acute stage of the disease. (wikipedia.org)
  • In the acute phase of the disease, changes in the peripheral extremities can include erythema of the palms and soles, which is often striking with sharp demarcation and often accompanied by painful, brawny edema of the dorsa of the hands or feet. (wikipedia.org)
  • The pathophysiology of MI can be broken into three phases of the disease process: the acute phase, the chronic compensated phase, and the chronic decompensated phase. (wikipedia.org)
  • Patients who receive a diagnosis of cardiac disease are more apt to have acute pain. (wikipedia.org)
  • pericardial
  • The experimental and in vitro testing of this novel device took place in 1970, and in March 1971, Ionescu began, for the first time, the implantation of the pericardial valve in all three cardiac positions in humans.Between 1971 and 1976 the valves had been made in Ionescu's own hospital laboratory. (wikipedia.org)
  • Throughout these five years of usage in 212 patients the performance of the pericardial valve was thoroughly evaluated. (wikipedia.org)
  • Based on these results, the Shiley Laboratory in Irvine, California, began to manufacture this valve and to distribute it worldwide under the name of the 'Ionescu - Shiley Pericardial Xenograft. (wikipedia.org)
  • These modifications had been progressively introduced and all of them were incorporated in the 'Ionescu - Shiley Low Profile Pericardial Xenograft' valve, which became available in 1983. (wikipedia.org)
  • Approximately 200,000 pericardial valves manufactured by Shiley Laboratories were distributed around the world between 1976 and 1987 and it is presumed that most of them were implanted in patients. (wikipedia.org)
  • Despite all these difficulties and impediments, a general view of the performance of the pericardial valve as close to reality as possible could be obtained. (wikipedia.org)
  • chronic
  • In chronic dyspnea likely due to diffuse pulmonary disease, when the diagnosis is unclear, high-resolution noncontrast computed tomography of the chest should be performed. (aafp.org)
  • symptoms
  • Kawasaki disease presents with set of mouth symptoms, the most characteristic changes are the red tongue, swollen lips with vertical cracking and bleeding. (wikipedia.org)
  • The course of the disease is better if you can prevent a crisis and stay ahead of the symptoms. (cavaliertalk.com)
  • There is great variability in the course of the disease in Cavaliers - some can start symptoms which will continuously and quickly worsen, leading to death within a year. (cavaliertalk.com)
  • His litter sister is in mid stage but with no symptoms and on no meds because she has kidney disease. (cavaliertalk.com)
  • Lyme disease, or borreliosis, is caused by Borrelia burgdorferi and spread by Ixodes pacificus on the West coast of the United States and by I. scapularis (deer tick) in the rest of the U.S. Signs and symptoms include fever, joint swelling and pain, lameness, and swelling of the lymph nodes. (wikipedia.org)
  • Play media The symptoms associated with MI are dependent on which phase of the disease process the individual is in. (wikipedia.org)
  • Turner syndrome, a congenital condition that affects females, can often have a bicuspid aortic valve as one of its symptoms. (wikipedia.org)
  • The need for surgery on the aortic valve (including repair procedures) is indicated through objective criteria and the presence of symptoms. (wikipedia.org)
