Cardiogenic shock remains a significant cause of mortality and morbidity in children with heart failure. Percutaneous mechanical circulatory support may be an additional tool to augment left heart support and decompression in addition to conventional therapies. This report aims to review the clinical and hemodynamic outcomes of the Impella® device at a pediatric center. A retrospective review of all implants between October 2014 and November 2016 was conducted. Clinical outcomes, device implant techniques, complications, and hemodynamic data were collected. Statistical analysis was performed on hemodynamic and echocardiographic data. There were 10 Impella® device placements in 8 patients with a median age of 17 years (6.5 - 25) and support duration of 8 days (1-21). Implant diagnosis included 5 patients with either post-transplant rejection or allograft vasculopathy, 2 with myocarditis, and one patient with refractory ventricular tachycardia. ECMO support was required in 4 patients. Significant reduction in pulmonary capillary wedge pressures (p<0.039) and increase in near infrared spectroscopy (p=0.039) was seen pre and post Impella® implant. All patients survived to discharge from the intensive care unit with one late death. Percutaneous mechanical circulatory support is a viable option in experienced pediatric centers as a mode to augment cardiac output or to decompress the left heart in patients on ECMO or with cardiogenic shock.
