Percutaneous transluminal coronary angioplasty (PTCA) has extended its indications to multivessel disease and impaired left-ventricular function. In these patients, failed PTCA may induce cardiogenic shock or arrest. Coronary and circulatory support devices such as antegrade perfusion catheters, coronary sinus retrograde perfusion, intraaortic balloon pumping, left-ventricular pumping (Hemopump) and percutaneously applicable cardiopulmonary support are the tools necessary for high-risk PTCAs. The devices are a prerequisite for developing a minimally invasive cardiac surgery.
经皮腔内冠状动脉成形术（PTCA）的适应证已扩展至多支血管病变和左心室功能受损的患者。在这些患者中，PTCA失败可能会诱发心源性休克或心脏骤停。冠状动脉和循环支持设备，如顺行灌注导管、冠状静脉窦逆行灌注、主动脉内球囊反搏、左心室泵血（Hemopump）以及经皮应用的体外膜肺氧合，是高危PTCA所需的工具。这些设备是开展微创心脏手术的先决条件。
