AIMS Myocardial work is a novel echocardiographic algorithm that corrects speckle-tracking-derived global longitudinal strain (GLS) for afterload using non-invasive systolic blood pressure as a surrogate for left ventricular systolic pressure (LVSP). Yet,

Abstract Aortic valvuloplasty for calcific aortic stenosis requires the removal of large calcified plaques from the leaflets, particularly at the hinge areas at the bases of the leaflets, and opening the commissures to the annulus. By this technic the leaflets are made flexible, and an adequate and competent valve can be obtained in the large ...

Expert Review of Cardiovascular Therapy, 2004
Aortic stenosis is the most commonly encountered valvular disease in the elderly, with approximately 2-3% of individuals over 65 years of age afflicted. The most common cause of acquired aortic stenosis is calcific degeneration, characterized by a slowly progressive, asymptomatic period which can last decades.

Catheterization and Cardiovascular Diagnosis, 1989
AbstractA 56 year‐old woman presented in congestive heart failure 4 weeks after cardiac catheterization. By repeat catheterization, the mean gradient across the native aortic valve had progressed from 10 mm Hg to 51 mm Hg. In patients with calcific‐degenerative valvular disease, the rapid worsening of aortic stenosis should be considered in the ...

Current Treatment Options in Cardiovascular Medicine, 2000
Subvalvular aortic stenosis (SAS) is a congenital heart defect that causes fixed form of hemodynamically significant left ventricular outflow tract (LVOT) obstruction with progressive course. It has a spectrum of anatomy. It appears usually beyond infancy, causes left ventricular hypertrophy and myocardial dysfunction, and tends to involve the aortic ...

Calcific aortic stenosis (AS) is primarily a disease of the elderly, possessing features that are biomechanical as well as systemic and inflammatory in nature, with risk factors and histopathology similar to atherosclerosis. To date no medical therapy has been shown to conclusively alter the progression of the disease, and for those with symptomatic AS,

Expert Review of Cardiovascular Therapy, 2005
Neonatal aortic stenosis is a complex and heterogeneous condition, defined as left ventricular outflow tract obstruction at valvular level, presenting and often requiring treatment in the first month of life. Initial presentation may be catastrophic, necessitating hemodynamic, respiratory and metabolic resuscitation. Subsequent management is focused on
