介入性治疗是应用心导管技术,达到纠治心血管病的目的,因此又称导管治疗学(Catherapy),从事介入性治疗的医师称导管治疗学家(Catherapist)。可见介入性治疗是一门高度专业化的治疗新技术,已成为介入性心脏病学的主要内容。冠心病的介人性治疗经皮冠状动脉腔内成形术(PTCA)始于1979年,而腔内成形用于外周动脉早已盛行,不过PTCA要求更高的技术条件和设备,它必须在冠状动脉造影(CAG)基础上进行。开始仅选单支冠状动脉狭窄者,现PTCA的病例已超过冠状动脉架桥手术。多支病变、冠状动脉开口处狭窄也选用PTCA。术后心绞痛的缓解率可达90％左右,手术并发症不多。术中冠状动脉
Interventional therapy is the use of cardiac catheterization technology to achieve the purpose of correcting cardiovascular diseases. Therefore, it is also known as Catherapy and the physician engaged in interventional therapy is referred to as Catherapist. Visible interventional treatment is a highly specialized treatment of new technologies, has become the main content of interventional cardiology. Interventional treatment of coronary heart disease Percutaneous transluminal coronary angioplasty (PTCA) began in 1979, while the use of endoluminoplasty for peripheral arteries has long been prevalent, but PTCA requires higher technical conditions and equipment, it must be in coronary angiography (CAG) on the basis of. The beginning of only a single coronary artery stenosis, PTCA cases have been more than coronary artery bypass surgery. Multivessel disease, coronary stenosis also use PTCA. Postoperative angina pectoris remission rate of up to 90%, few surgical complications. Intraoperative coronary artery
