[A 2-stage method for the surgical correction of calcified aortic stenosis in patients with an extreme degree of risk for an operation].

During the period of 1992-1998 the authors dealt with treatment of 32 patients with aortic stenosis under extreme risk of operation. All the patients were considered to be inoperable because of the severity of their state. At the first stage of operation the catheter balloon valvuloplasty (CBV) was performed for decompression of the left ventricle since it was the only possible variant at this stage of surgical treatment. Good results of CBV were obtained in 22 patients which led to the possibility to perform the prosthetizing of the aortic valve in 13 patients within two months at an average. There were no lethal outcomes. Long-term results followed-up during 6 years were estimated as satisfactory.
