Despite the many advances in the management of patients with acute heart failure, the outcome for patients with refractory acute cardiogenic shock remains disproportionately poor. Clearly, there is a definitive role for wider application of temporary circulatory support in such patients. ⋯ There are currently several options available for circulatory support and include surgically implanted ventricular assist devices, percutaneous assist devices, and extracorporeal membrane oxygenation. This review includes a brief summary of the current assist devices available along with the University of Minnesota's experience with the Levitronix CentriMag system.

Cardiogenic shock following acute myocardial infarction affects 5% to 10% of patients and carries a grave prognosis. The dismal prognosis associated with post-MI cardiogenic shock, allied with surgical and technological advancements, has shifted the treatment paradigm toward wider use of mechanical circulatory support devices (MCSD). ⋯ However, perceived limitations with existing devices mean that they remain infrequently applied. There is an urgent need for increased awareness of MCSD options among clinicians treating post-MI shock patients.

Comparative Study
Symptomatic young infants with tetralogy of fallot: one-stage versus staged repair.
Debate continues over the optimal timing for total repair of tetralogy of Fallot. Here, we report our experience with early one-stage total repair of tetralogy of Fallot. ⋯ Early one-stage total repair of tetralogy of Fallot can be performed safely without increasing the risk for reoperation or reintervention, in the short term. The pulmonary annulus is likely to be preserved when it is repaired at an early age. Early total repair may be better for the pulmonary arterial growth than staged repair.

Case Reports
Thoracic endovascular aortic repair of an aberrant right subclavian artery: technique and long-term outcome.
Aberrant right subclavian artery (ARSA) is the most common congenital arch anomaly, which can be complicated by aneursymal dilation at its ostium. We describe a successful repair of an ARSA with a three-stage operative procedure using a left carotid to subclavian bypass, coiling of the ARSA, and thoracic endovascular aortic repair with long-term clinical and radiographic follow-up.
