Aortic valve prosthetic replacement in children and adolescents helps to improve their haemodynamics, and favourably affects the course of the rheumatic process. The correction of the defect is indicated in the presence of appropriate subjective and objective symptoms of aortic valve insufficiency. The lumen of the aorta was so large in many children that it permitted the employment of prostheses for adults. Calcification of the aortic valve was found in 9 of the 31 patients, which contradicts the commonly accepted belief of a low incidence of calcification in this disease in children. Hospital mortality and postoperative complications rate did not exceed those in aortic valve replacement in adults. The comparatively fast reduction of the heart size and the positive dynamics of the functional parameters in children and adolescents may be due to the high plasticity of the cardiovascular system in this age-group.
儿童和青少年的主动脉瓣人工置换有助于改善其血流动力学，并对风湿病程产生有利影响。当存在主动脉瓣关闭不全的适当主观和客观症状时，就需要对缺陷进行矫正。许多儿童的主动脉腔很大，以至于可以使用成人型假体。在31例患者中有9例发现主动脉瓣钙化，这与普遍认为的儿童该疾病钙化发生率低的观点相矛盾。医院死亡率和术后并发症发生率未超过成人主动脉瓣置换的情况。儿童和青少年心脏大小相对较快的缩小以及功能参数的积极变化可能归因于该年龄组心血管系统的高可塑性。
