PTCA is now applied to patients with unstable acute ischemic syndromes, severe multivessel coronary artery disease, and impaired left ventricular function. To minimize the risk during angioplasty, several coronary and systemic circulation support approaches have been developed as adjuncts to high-risk angioplasty. Local coronary support techniques include the perfusion balloon catheter, the coronary stent, directional coronary atherectomy, laser balloon angioplasty, perfluorocarbon coronary perfusion, coronary sinus retroperfusion, and distal coronary hemoperfusion. Systemic circulatory support includes intraaortic balloon counterpulsation, cardiopulmonary support, the hemopump, and left heart partial bypass. These support devices, while associated with significant complications, may ultimately improve the safety of coronary angioplasty and allow its application to those who would otherwise not be candidates for revascularization.
经皮冠状动脉腔内血管成形术（PTCA）目前应用于不稳定型急性缺血综合征、严重多支冠状动脉疾病及左心室功能受损的患者。为将血管成形术期间的风险降至最低，已开发出多种冠状动脉和体循环支持方法作为高危血管成形术的辅助手段。局部冠状动脉支持技术包括灌注球囊导管、冠状动脉支架、定向冠状动脉斑块旋切术、激光球囊血管成形术、全氟碳冠状动脉灌注、冠状静脉窦逆行灌注及冠状动脉远端血液灌注。体循环支持包括主动脉内球囊反搏、心肺支持、血液泵及左心部分旁路。这些支持装置虽伴有严重并发症，但最终可能会提高冠状动脉血管成形术的安全性，并使其能够应用于那些原本不适合进行血运重建的患者。
