Randomized Controlled Trial Multicenter Study
Elective intra-aortic balloon counterpulsation during high-risk percutaneous coronary intervention: a randomized controlled trial.
Observational studies have previously reported that elective intra-aortic balloon pump (IABP) insertion may improve outcomes following high-risk percutaneous coronary intervention (PCI). To date, this assertion has not been tested in a randomized trial. ⋯ Elective IABP insertion did not reduce the incidence of MACCE following PCI. These results do not support a strategy of routine IABP placement before PCI in all patients with severe left ventricular dysfunction and extensive coronary disease.
