Shortly after the diagnosis of aortic stenosis
and systolic myocardial failure was established, the patient was put on diltiazem (0.42mg [kg.sup.-1] TID PO), digoxin (0.005mg [kg.sup.-1] BID PO), enalapril (0.42mg [kg.sup.-1] BID PO) and furosemide (2mg [kg.sup.-1] TID SQ).
The valve currently stands as the largest available in the healthcare industry to treat severe aortic stenosis
patients with large anatomies.
Altered hemodynamics due to aortic stenosis
and regurgitation and also defects in aortic media like elastin fragmentation, decreased fibrillin, matrix disruption, loss of smooth muscle and increase in collagen have been thought to be the cause.
A study carried out by Torres A in 373 patients with aortic stenosis
with median systolic pressure was 59 (50-71) mm of Hg before balloon valvuloplasty and 22 (15-30) after the procedure.
Although many people with aortic stenosis
find out about their disease incidentally when their doctor hears a murmur while listening to their heart, others progress to more severe disease, with symptoms such as fatigue, shortness of breath, faintness (syncope), and chest pain.

While patients in these studies had aortic valve calcification, there was high prevalence of aortic stenosis

This condition, called aortic stenosis
, can be the result of a congenital heart defect called bicuspid aortic valve.
