16 ECMO and MCS for patients undergoing PCI: experience from taipei veterans general hospital

Intra-aortic balloon pump (IABP), which simultaneously augments coronary blood flow and decreases myocardial oxygen demand, usually provides haemodynamic support in patients with impaired left ventricular function undergoing percutaneous coronary intervention (PCI)1 2 or for patients with established cardiogenic shock.3 Several observational studies have reported that prophylactic IABP insertion could reduce major adverse cardiovascular events (MACE) compared with a provisional counterpulsation strategy during high-risk PCI.4 However, meta-analysis did not reveal a benefit of routine elective use of IABP or percutaneous ventricular assisted device.5 Due to a lack of national data from Taiwan, this presentation therefore summarises the experience at Taipei Veterans General Hospital, and the patients’ clinical characteristics and long-term outcomes including cardiac mortality and MACE associated with high-risk PCI and/or acute myocardial infarction.
