[Prosthesis of the aortal valve in adult patients with "narrow" aortic root].
Results of treatment of 54 patients with aortal valvular disease and "narrow" aortic root are analyzed. Only adult patients were included in the study, their age ranged from 16 to 64 years (mean age 41.5+/-14.7 yrs). Thirty-four (63%) patients of them have undergone aortic valve replacement with disk prosthesis, in 20 (37%) patients this surgery was supplemented with dillative plasty of fibrous ring and aortic root by Nicks's method. The proposed algorithm of choosing the most effective operation in patients with the aortal defect and narrow aortal root permits one to avoid pathologic pressure gradient between the left ventricle and the aorta after surgery and to achieve the most favorable clinical effect.
