Timing of Intra-Aortic Balloon Pump Placement Before Off-Pump Coronary Artery Bypass Grafting and Clinical Outcomes.

abstract：:Mechanical circulatory support (MCS) devices for pediatric patients continue to lag in development behind those for adults. There is no heart pump with the design innovation to support dysfunctional states of heart failure and the anatomic heterogeneity of cardiac defects in pediatric patients. To address this unmet n...
