大多數血管直徑狹窄超過50%的左主冠狀動脈疾病患者會出現臨床症狀,同時也是發生嚴重心血管事件的高危險群。在一位83歲女性患者,Dipyridamole鉈-201單光子斷層造影檢查除了偵測出嚴重左主冠狀動脈疾病,還導引安全的心導管檢查程序,並促成即時的經皮冠狀動脈介入性治療,從而防止災難性事件的發生。
Most patients with significant, defined as a greater than 50% diameter narrowing, left main coronary artery disease (LMCAD) are symptomatic and at high risk of serious cardiovascular events. We present an 83-year-old female patient with symptomatic LMCAD. In this case, dipyridamole Tl-201 SPECT myocardial perfusion imaging, besides detecting LMCAD, guided a safe diagnostic catheterization procedure and culminated in prompt percutaneous coronary intervention which had prevented a catastrophic event.
