The purpose of this study was to compare the opening and closing sounds of three different mechanical mitral valves and to analyze their effects on the quality of life of patients.
Ninety patients who underwent mechanical mitral valve replacement (MVR) were divided into three groups: those who received Advancing the Standard (ATS), St. Jude Medical (SJM), or Carbomedics (CM) mechanical valves. The sound pressure of the different valves was measured with a microphone. A detailed, self-designed questionnaire with a 1 to 10 analog scale and the 36-item Short Form Health Survey (SF-36) score was used to assess the quality of life of the patients.
The sound pressure measured by ATS was 64.4 ± 3.1 dB, while that measured by SJM, and CM was 64.5 ± 4.7 and 67.2 ± 5.3 dB, respectively. The overall subjective interference score in the ATS group was the lowest compared with that in the SJM and CM groups (ATS: 1.3 ± 0.9 dB, SJM: 3.9 ± 1.6 dB, CM: 4.1 ± 1.5 dB). Relatives and nonfamily members of the ATS group also had the lowest analog scale scores. Specific questions showed that the ATS valve had the least impact on sleep and daily life (impact on sleep: ATS: 4/30, SJM: 9/30, CM: 11/30, impact on daily life: ATS: 2/30, SJM: 8/30, CM: 8/30). The SF-36 score showed that there were significant differences in social functioning, role-emotional, mental health, and vitality.
Patients receiving ATS mechanical MVR may be less disturbed by valve noise than those receiving SJM or CM mechanical MVR in a single Chinese cardiac center.
本研究旨在比较三种不同机械二尖瓣的开合声音，并分析其对患者生活质量的影响。
90例行机械二尖瓣置换术（MVR）的患者被分为三组：分别接受标准推进（ATS）、圣犹达医疗（SJM）或卡波美迪克斯（CM）机械瓣膜的患者。用麦克风测量不同瓣膜的声压。使用一份详细的、自行设计的采用1至10模拟量表的问卷以及36项简短健康调查（SF - 36）评分来评估患者的生活质量。
ATS测量的声压为64.4±3.1dB，而SJM和CM测量的声压分别为64.5±4.7dB和67.2±5.3dB。与SJM和CM组相比，ATS组的总体主观干扰评分最低（ATS：1.3±0.9dB，SJM：3.9±1.6dB，CM：4.1±1.5dB）。ATS组的亲属和非家庭成员的模拟量表评分也最低。具体问题显示，ATS瓣膜对睡眠和日常生活的影响最小（对睡眠的影响：ATS：4/30，SJM：9/30，CM：11/30；对日常生活的影响：ATS：2/30，SJM：8/30，CM：8/30）。SF - 36评分显示，在社会功能、角色情感、心理健康和活力方面存在显著差异。
在单一中国心脏中心，接受ATS机械MVR的患者可能比接受SJM或CM机械MVR的患者受瓣膜噪音干扰更少。
