Objective: To investigate the clinical effect of PBAV in the treatment of senile CAS complicated with cardiac insufficiency. Methods: From June 2015 to June 2017, 64 patients with senile CAS complicated with cardiac insufficiency were selected. All patients were randomly divided into control group (n=32) and observation group (n=32).The control group was treated with drug therapy and the observation group with percutaneous aortic valve balloon dilatation. The indexes of echocardiography (maximum transvalve pressure difference, mean transvalve pressure difference, aortic valve area, LAD, LVESD, LVEDD, LVEDV, LVEF) and NYHA cardiac function grading were compared between the two groups before and after operation. And the quality of life score and the incidence of complications 1 month after operation were compared between the two groups. Results: Compared with the control group, the maximum transvalve pressure difference, the average transvalve pressure difference and the aortic valve orifice area in the observation group were significantly decreased (P<0.05). There was no significant difference in LAD, LVEDD, LVEDV, LVEF between the two groups after treatment. After treatment, compared with the control group, the NYHA cardiac function grade of the observation group was significantly lower, the scores of health feeling, somatosensory, sleep state and other quality of life of the patients in the observation group were significantly higher (P<0.05).One month after treatment, the incidence of complications in the control group and the observation group was 40.63% and 31.25%, respectively (P>0.05). Conclusion: Percutaneous balloon aortic valvuloplasty is effective in the treatment of senile calcified aortic stenosis.
