Abstract Aortic valve stenosis (AS) is the most prevalent valvular heart disease and is increasingly diagnosed in high-income countries due to an ageing population but also to more widely available diagnostic tools. The prevalence of AS is estimated at ~0.5% in the general population, ~2–3% in the population over 65 years old.

Postgraduate Medicine, 1993
Aortic valve stenosis may be congenital or acquired. Medical management includes advice to avoid heavy physical effort, prevention of infective endocarditis, use of digitalis and diuretics for cardiac failure, and preservation of atrial systole. When operation is necessary, open aortic valve commissurotomy is preferred in children and replacement of ...

Abstract Echocardiography is the method of choice for the diagnosis, assessment of morphology, and aetiology, as well as quantification of aortic valve stenosis. It permits the additional evaluation of the consequences on left ventricular size and, function, wall thickness, mitral valve (functional regurgitation).Haemodynamic assessment ...

Aortic Valve Replacement for Aortic Stenosis in Nonagenarians
The American Journal of Cardiology, 2006We reviewed certain clinical and morphologic findings in 9 patients who had aortic valve replacement (AVR) for aortic stenosis (AS) when >or=90 years of age. All had AVR from February 2000 to April 2006. The aortic valve areas ranged from 0.41 to 1.00 cm2, and the transvalvular peak systolic gradients ranged from 20 to 110 mm Hg.

Indications for Aortic Valve Replacement in Aortic Stenosis
Journal of Intensive Care Medicine, 2007Aortic stenosis is a common condition, particularly in the elderly. The treatment is surgical, and any patient with symptomatic severe aortic stenosis should be considered for aortic valve replacement. Aortic stenosis causes an increase in afterload to the left ventricle, which when severe can lead to hemodynamic instability.

Translocation of aortic valve for calcific aortic stenosis
The Japanese Journal of Thoracic and Cardiovascular Surgery, 2000A 56-year-old man underwent surgery for treatment of severe calcific aortic stenosis. Because it was found after excision of the aortic valve that calcification of the annulus was too extensive for the placement of sutures, translocation of the aortic valve was performed.

Progression of aortic valve sclerosis to aortic stenosis
The American Journal of Cardiology, 2003level or low-density lipoprotein cholesterol and high-density lipoprotein cholesterol concentrations. Itwould be interesting to know the effects of thesefactors on severe calcific AS.In summary, this large case-control study showsthat the development of severe AS caused by thecalcific degenerative process is not simply a conse-quence of aging.

Aortic valve stenosis is the most frequent reason for prosthetic valve replacement in adults. Its incidence increases with age. Development of the most frequent form, degenerative-calcific aortic stenosis, is related to atherosclerotic risk factors. The narrowing of the aortic valve orifice leads to creation of a systolic pressure drop, the gradient ...

Aortic valve repair for aortic stenosis in adults
The Annals of Thoracic Surgery, 1990The stenotic aortic valve was surgically repaired in 48 adults, 21 women and 27 men, aged 38 to 83 years. Five had congenital aortic stenosis (AS), with a mean aortic valve gradient and area of 58 +/- 23 mm Hg (standard deviation) and 0.54 +/- 0.13 cm2, respectively; 32 had senile AS with a mean aortic valve gradient and area of 43 +/- 20 mm Hg and 0 ...

Transcatheter aortic valve replacement in unicuspid aortic valve stenosis
Catheterization and Cardiovascular Interventions, 2016Unicuspid aortic valve (UAV) offers unique challenges to transcatheter aortic valve replacement (TAVR), due to asymmetric expansion and apposition of the prosthesis during implantation. Although TAVR in bicuspid is now a well described experience, TAVR in unicuspid valve has not yet been described. A challenging case is described with TAVR in UAV using
