本文报道７０例经皮腔内冠状动脉成形术（ＰＴＣＡ）的造影初步经验。作者们将冠心病冠状动脉造影发现的冠状动脉狭窄形态分为单纯型与复杂型。本组结果显示，稳定型劳累性心绞痛常为单纯型病变，而冠心病的其它类型常为复杂型病变。还发现，单纯型病变在经皮腔内冠状脉动脉成形术后，很少发生再狭窄，但复杂型则常发生再狭窄。本文还讨论了当前经皮腔内冠状动脉成形术的造影特点和Ｘ线投照技术的重要性。
This article reports the initial experience of 70 cases of percutaneous transluminal coronary angioplasty (PTCA). The authors categorized coronary stenosis as coronary artery disease by coronary angiography as simple and complex. The results of this group show that stable exertional angina often simple lesions, and other types of coronary heart disease often complex lesions. Also found that simple lesions in percutaneous transluminal coronary angioplasty, the restenosis rarely occurs, but the complex often occurs restenosis. This article also discusses the current percutaneous transluminal coronary angioplasty angiography features and the importance of X-ray projection technology.
