Closing click of St Jude Medical and Duromedics Edwards ... | 合法醫療器材資訊網
The metallic clicking sound created by mechanical heart valve prostheses frequently bothers patients. To test whether sounds generated by different bileaflet valves correlate to complaints related to the prosthetic clicking 73 patients were investigated after valve replacement with Duromedics Edwards (DE) (n = 38) and St Jude Medical (SJM) (n = 35) valves. The patients were asked about their complaints, sound pressure levels were recorded and audiometry was performed. Sixty-five percent of patients could hear their valve, 18% had sleeping disturbances, 5% felt bothered during daytime and 12% would prefer a less noisy valve. In symptomatic patients, sound pressure levels were higher than in asymptomatic patients (valve audible 45 +/- 8 db(A) vs not audible 39.9 +/- 10 db(A) at 10 cm; P = 0.016). These differences were most apparent in the high frequency bands, corresponding to the metallic click. Symptomatic patients...
