OBJECTIVE: The authors investigated the preprocedural predictors of postprocedural intra-aortic balloon pump (IABP) need in patients undergoing transcatheter ventricular tachycardia (VT) ablation on venoarterial (VA) extracorporeal membrane oxygenation (ECMO).
DESIGN: Observational study.
SETTING: Hybrid operating room and intensive care unit of a teaching hospital.
PATIENTS: Participants were 121 consecutive patients with unstable VT undergoing transcatheter ablation with VA-ECMO.
INTERVENTIONS: In patients with postprocedural echocardiographic, radiographic, or hemodynamic signs of increased left ventricle afterload, an IABP was positioned.
MEASUREMENTS AND MAIN RESULTS: Patients in the IABP group were more frequently on angiotensin-converting enzyme inhibitors (58% v 37%; p = 0.03) and had lower median baseline ejection fraction (25% v 28% p = 0.05), larger end-diastolic diameter (69.7 mm ± 13.0 v 65.7 mm ± 11.3; p = 0.03), and more frequent ischemic etiology as the reason for dilated cardiomyopathy (76% v 47%; p = 0.04,) when compared with patients not requiring IABP. Postoperatively, the IABP group required longer mechanical ventilation (24 hours [20-56.5] v 23 hours [15-28]; p = 0.003), intensive care unit stay (78 hours [46-174] v 48 hours [24-72]; p < 0.001), and continuous renal replacement therapy (13.3% v 1.3%; p = 0.006). By multivariate analysis, end-diastolic diameter (odds ratio [OR]:1.08; confidence interval [CI]: 1.00-1.16; p = 0.049), ischemic dilated cardiomyopathy (OR: 8.40; CI: 2.15-32.88; p = 0.002), and more-than-moderate mitral regurgitation (OR: 4.83; CI: 1.22-19.22; p = 0.025) were independent predictors of need for IABP.
CONCLUSIONS: The need for an IABP to unload the left ventricle can be predicted by ventricular size, medium-severe mitral valvular defect, and ischemic etiology of the dilated cardiomyopathy.
