主动脉瓣退行性钙化(AVDC)是老年人心血管系统的常见心瓣膜病,临床意义主要取决于瓣膜功能的状况。其发病率随年龄的增长而增加,本病起病隐匿,临床表现隐袭,因此,二维彩色超声心动图已成为该病诊断的主要手段。我们采用此项技术分析50岁以上AVDC的检出率,心瓣膜功能失调发生率及心脏听诊对心瓣膜功能失调的评价。 Aortic valve degenerative calcification (AVDC) is a common heart valve disease in the elderly cardiovascular system, the clinical significance depends on the status of valvular function. Its incidence increases with age, the disease occult onset, implicit clinical manifestations, therefore, two-dimensional color echocardiography has become the main means of diagnosis of the disease. We used this technique to analyze the prevalence of AVDC over 50 years of age, the incidence of cardiac valve dysfunction, and the evaluation of cardiac auscultation of valvular dysfunction.
