Ultrasonic Evaluation Of Relationship Between Aortic Valve Calcification And Artery Atherosclarosis

SubjectTo determine whether there is an association between the presence of aortic valve calcification and lower extremity artery atherosclerotic disease.Materials and Methods74 aged patients were performed transthoracic echocardiography and lower extremity artery sonography.All the patients were divided to two groups-the AVC group and the non-AVC group as control.For the AVC examination, we recorded the three aortic valves and recorded the valvar thickness, echo features,and movement.For the lower artey extremity examination, we recorded the intima-media thicknes(IMT) and the various plaques parameters, such as the number of plaques,the detection rate of plaques, the plaques burden and plaques index.The messages of gender, diabetic history, hyperlipoidemia history, and hypertension history were recorded to analyzed the correlative risk factors with aortic calcificationResults1. The intima-media thickness(IMT),the incidence rate of the atherosclerosis plaques and various plaque parameters of AVC group were higher than those of the control group. There were no statistical difference in the echo and site of the plaques between AVC and control group.2. There were no statistical difference in the gender, diabetic history, hyperlipoidemia history, and hypertension history history between AVC and control group.3. The intresting found was that there were significant difference between AVC group and the control group in lower extremity artery atherosclerosis echo characteristics especially in anterior tibial artery, posterior artery, dorsal is pedis artery.ConclusionsThere is significant correlation between the incidents of AVC and lower extremity artery atherosclaresis. The color Doppler ultrasound Of lower extremity artery may predict the severity of aortic valve calcification. In contrast, the aortic valve calcification can predict the lower extremity artery atherosclerosis.
