Abstract:
Objective To study the characteristics of calcific valvular heart disease (CVHD) with the aid of echocardiography. Methods Nine thousand and seventeen patients over 50 year-old who had received transthoracic echocardiographic examination were enrolled in the study. Diagnosis of CVHD was made with 2 dimension, M-mode and color Doppler echocardiography. General state of health, clinical manifestation and history of CVHD patients were also analyzed. Results Five hundred and seventy-four cases of CVHD were diagnosed and the characteristics of CVHD were observed. The diagnostic rate increased as the age increased. There was no significant difference between male and female. The calcified regions were commoner in aortic valves than in mitral valves, more frequent in non-coronary valves than in right or left coronary valves, and more frequently seen at tips of aortic valves and annuli of mitral valves than in other parts. The size of calcific plaques was usually between 3 and 10mm. Hemodynamic changes could be found in some patients. History of hypertension, coronary artery disease, and arteriosclerosis of the aorta were often found in these patients. Conclusions Echocardiography can be used to evaluate the position of calcification, size of calcification area, and degree of valvular stenosis or insufficiency, thus offers useful information for early diagnosis and treatment, and prognosis of CVHD in clinic.
