Long-Term Mortality Data From the Balloon Pump―Assisted Coronary Intervention Study (BCIS-1): A Randomized, Controlled Trial of Elective Balloon Counterpulsation During High-Risk Percutaneous Coronary Intervention

There is conflicting evidence on the utility of elective intra-aortic balloon pump (IABP) use during high-risk percutaneous coronary intervention (PCI). Observational series have indicated a reduction in major in-hospital adverse events, although randomized trial evidence does not support this. A recent study has suggested a mortality benefit trend early after PCI, but there are currently no long-term outcome data from randomized trials in this setting. Three hundred one patients with left ventricular impairment (ejection fraction
