采用常规无创性方法检查心瓣膜病人的冠状动脉病变可能是困难的。对于冠状血管造影术检查的16例主动脉狭窄、17例主动脉回流、9例二尖瓣狭窄和6例二尖瓣回流的病人,评价了~(201)铊运动闪烁图检查冠状动脉疾病的价值。在21例冠状动脉阻塞≥50％的病人中,仅2例的铊闪烁图正常。3例血管造影没有冠状动脉狭窄证据的病人,通过铊闪烁图证实有灌注缺损。
It may be difficult to examine coronary artery lesions in patients with heart valves using conventional noninvasive methods. A total of 16 patients with aortic stenosis, 17 with aortic regurgitation, 9 with mitral stenosis and 6 with mitral regurgitation under coronary angiography were evaluated for ~ (201) thallium motor scintigraphy for coronary artery disease value. In 21 patients with coronary occlusion ≥50%, thalidomide scintigraphy was normal in only two patients. Three patients with evidence of angiographic coronary artery stenosis demonstrated perfusion defects by thallium scintigraphy.
