[Transcutaneous balloon aortic valvuloplasty as the 1st stage of surgical treatment of aortic valve stenosis].

The results of conduction of transcutaneous balloon aortic valvuloplasty in 99 patients were analysed. After the operation conduction was noted the systolic pressure gradient lowering on aortal valve by 67.8% from the initial one. In 28.3% of patients in such conditions the retrograde blood flow to aorta occurs or enhances, but in 7% of patients only the substantial aortic regurgitation increase by 2 points occurs. The occurrence or enhancement of retrograde blood flow in the aorta is more probable if there is a two cuspid valve and while the two balloon method application. Hospital mortality in the intervention performance had constituted 4%.
