目的:评价~(99m)Tc-MIBI 心肌灌注显像术前了解瓣膜患者心肌缺血的诊断价值。材料与方法:81例瓣膜患者行术前核素心肌断层显像,并与冠状动脉造影,超声心动图及手术后结果进行对比。72例瓣膜患者做瓣膜置换术,其中9例同时做冠状动脉搭桥术。结果:41例做冠状动脉造影检查,结果阳性符合率95.5%,阴性符合率100%,提示病变部位一致率85.7%,总符合率97.6%。结论:40岁以上风湿性瓣膜病患者合并冠心病发病率很高,对于需手术治疗的患者,有必要通过心肌灌注断层显像和冠状动脉造影确诊瓣膜病合并冠状动脉疾病,有利于瓣膜手术与冠状动脉手术同时进行,免去两次手术,提高治愈率具有重要价值。
Objective: To evaluate the value of ~ (99m) Tc-MIBI myocardial perfusion imaging in the diagnosis of myocardial ischemia in patients with valvular heart disease. MATERIALS AND METHODS: Totally 81 patients with valvular heart disease underwent preoperative radionuclide myocardial imaging and compared with coronary angiography, echocardiography and postoperative results. Valve replacement was performed in 72 patients with valvular heart disease, in which 9 patients underwent coronary artery bypass grafting at the same time. Results: 41 cases underwent coronary angiography, the positive coincidence rate was 95.5%, the negative coincidence rate was 100%, suggesting that the consistency rate of the lesion was 85.7% and the total coincidence rate was 97.6%. Conclusion: Patients with rheumatic valvular disease over the age of 40 have a high incidence of coronary heart disease. It is necessary to diagnose valvular disease with coronary artery disease by myocardial perfusion tomography and coronary angiography in patients undergoing surgical treatment, which is beneficial to valvular surgery Coronary artery surgery at the same time, eliminating the need for two operations, improve the cure rate is of great value.
