Calcific Aortic Stenosis

چکیده
To evaluate the short-term results of percutaneous aortic balloon valvuloplasty, 55 consecutive elderly patients with symptomatic, severe aortic stenosis who were at high risk for surgical intervention underwent the procedure, with follow-up by clinical evaluation and Doppler echocardiography. Over a mean follow-up of 6.2 months, there were three early deaths (<30 days) and eight late deaths. Nine patients underwent subsequent aortic valve surgery, and four had repeat balloon valvuloplasty. Doppler echocardiography revealed a reduction in aortic valve mean gradient from 48±18 to 33±12 mm Hg after the procedure (p<0.0001) but a return to 46±16 mm Hg at follow-up (p<0.05). The aortic valve area increased from 0.54±0.15 to 0.85±0.23 cm2 after the procedure (p<0.0001), but there was a significant decrease to 0.67 ± 0.19 cm2 at follow-up (p<0.05). Of patients free of aortic valve operation or death after 30 days after the procedure, 76% were severely symptomatic before the procedure

OBJECTIVE To test the hypothesis that vitamin D receptor polymorphism is associated with calcific aortic valve stenosis. DESIGN The distribution of one polymorphism of the vitamin D receptor (BsmI B/b) was examined in 100 consecutive patients with calcific valvar aortic stenosis and compared with a control group of 100 patients (paired match for age, sex, and the presence of coronary artery d...
متن کاملCalcific cerebral emboli and aortic stenosis: detection of computed tomography.
Embolism with brain infarction rarely complicates calcific aortic stenosis (CAS). We report a case with severe CAS where the patient experienced multiple embolic strokes immediately following retrograde heart catheterization. Calcific emboli in the cerebral arteries were demonstrated by computed tomography (CT).

Calcific aortic stenosis is the third most common cause of aortic valve disease in developed countries. This condition increases in prevalence with advancing age, afflicting 2–3% of the population by the age of 65 years. The aging US population has led to a burgeoning number of valve replacements per year, which in turn costs the USA approximately $1 billion. The natural history, as described b...
متن کاملTargeted therapy to prevent progression of calcific aortic stenosis.
Calcific aortic valve disease is common, affecting 25% of adults over the age of 65 years, with progression to severe valve obstruction resulting in more than 50 000 aortic valve replacements annually in the United States. “Degenerative” calcific aortic valve disease was thought for many years to be a passive accumulation of calcium binding to the aortic surface of the valve leaflet. Now, convi...
متن کاملSystemic and local levels of fetuin-A in calcific aortic valve stenosis.
Calcific aortic valve stenosis, the most frequent heart valve disorder in developed countries, is an actively regulated process with similarities to bone formation. Fetuin-A has recently been identified as a potent circulating inhibitor of calcification. While several studies involving patients with end-stage renal disease have shown an association between low serum fetuin-A and cardiovascular ...
