Abstract

Background. We interviewed patients and carried out frequency analyses to compare the closing sounds of ATS and St. Jude Medical (STM) prosthetic valves. Methods. Forty-five patients undergoing valve replacements using ATS valves were investigated. We interviewed patients at 1 month and 1 year after the operation, and carried out frequency analysis to investigate the prosthetic valve's closing sound. Results. According to the results of the interviews, 84.4% of patients with ATS valves were not aware of the valve sounds. ATS valves scored significantly lower than SJM valves on audibility of the valve sound, disturbance during daytime, sleep disturbance, request for replacement with a soundless prosthetic valve, audibility to others, and noise index. According to the frequency analysis on the prosthetic valve's closing sound, the sound peak of the ATS valves was around 1.2 kHz, and the sound pressure of the ATS valves was significantly lower than that of the SJM valves. Conclusions. Though a further long-term observation on thromboembolism andhemolysis is needed for evaluation of prosthetic valves, the ATS valve is presently considered to impart a better quality of life.
