• echocardiography
  • In patients with aortic stenosis (AS), it has been demonstrated that increased left ventricular (LV) load induces changes in LV geometry in order to allow preservation of a normal ejection fraction in spite of reduced long-axis excursion by M-mode echocardiography, 1 and depressed LV myocardial systolic function. (bmj.com)
  • We sought to determine whether the dual-source computed tomography assessment of aortic valve stenosis and coronary artery disease is equivalent to or even better than conventional invasive coronary angiography and transthoracic echocardiography. (clinicaltrials.gov)
  • Fetal aortic valve stenosis can be diagnosed by echocardiography before birth. (wikipedia.org)
  • While this method directly measures the valve area, the image may be difficult to obtain due to artifacts during echocardiography, and the measurements are dependent on the technician who has to manually trace the perimeter of the open aortic valve. (wikipedia.org)
  • In echocardiography the aortic valve area is calculated using the velocity time integral (VTI) which is the most accurate method and preferred. (wikipedia.org)
  • Aortic stenosis can be diagnosed by auscultation for characteristic heart sounds, particularly a crescendo-decrescendo (i.e., 'ejection') murmur, followed by echocardiography to measure aortic valve area (see diagnosis of aortic stenosis). (wikipedia.org)
  • Circulation
  • However, the ductus arteriosus closes during the first few days of life, resulting in systemic circulation failure in babies born with aortic valve stenosis. (wikipedia.org)
  • The atrial septum is removed, the aortic arch is reconstructed to remove any hypoplasia, and then the main pulmonary artery is connected into this reconstructed arch, resulting in the right ventricle ejecting directly into systemic circulation. (wikipedia.org)
  • Heyde's
  • Heyde's syndrome is now known to be gastrointestinal bleeding from angiodysplasic lesions due to acquired vWD-2A deficiency secondary to aortic stenosis, and the diagnosis is made by confirming the presence of those three things. (wikipedia.org)
  • aneurysm
  • It can also become necessary for the treatment of aortic aneurysm, less frequently for congenital aortic stenosis. (wikipedia.org)
  • The details of the aortic valve repair procedure depend on the possibility of congenital malformation of the valve, the type and degree of secondary deformation, and the existence of an aortic aneurysm. (wikipedia.org)
  • The results of this analysis including the possible presence of an aortic aneurysm then determine the plan for the repair procedure which must be individualized for every patient. (wikipedia.org)
  • treatment
  • This discovery holds promise for elucidation of the pathophysiology of aortic valve disease mechanisms and for the design of effective nonsurgical treatment. (ahajournals.org)
  • As a result, treatment of multiple valve problems depends on the combination of problems and which problem is in more urgent need of treatment. (lancastergeneralhealth.org)
  • Another treatment option is to correct the stenosis in utero. (wikipedia.org)
  • 50mm and risk factors and connective tissue disease The goal of the operation is the improvement of life expectancy and treatment of heart failure as the consequence of dysfunction of the aortic valve. (wikipedia.org)
  • Following unsuccessful treatment in Vienna in early 2011, Anania died in Cluj-Napoca of heart failure and aortic valve stenosis at age 89. (wikipedia.org)
  • ejection
  • Valve Area (cm 2 ) = Cardiac Output ( ml min ) Heart rate ( beats min ) ⋅ Systolic ejection period (s) ⋅ 44.3 ⋅ mean Gradient (mmHg) {\displaystyle {\text{Valve Area (cm}}^{2}{\text{)}}={\frac {{\text{Cardiac Output }}({\frac {\text{ml}}{\text{min}}})}{{\text{Heart rate }}({\frac {\text{beats}}{\text{min}}})\cdot {\text{Systolic ejection period (s)}}\cdot 44.3\cdot {\sqrt {\text{mean Gradient (mmHg)}}}}}} The Gorlin equation is related to flow across the valve. (wikipedia.org)
  • orifice
  • For interpretation of these values, the area is generally divided by the body surface area, to arrive at the patient's optimal aortic valve orifice area. (wikipedia.org)
  • valvuloplasty
  • Some young people or pregnant women may have another procedure called balloon valvuloplasty to enlarge the valve opening. (webmd.com)
  • Another less invasive procedure, balloon aortic valvuloplasty (BAV) may result in benefit but this is for only for a few months. (wikipedia.org)
