Minimally Invasive Off-Pump Technique for Temporary Left Ventricular Support.

Use of short-term mechanical circulatory support (MCS) for cardiogenic shock has rapidly increased. Most common initial MCS strategies entail institution of peripheral extracorporeal membrane oxygenation (ECMO) or temporary ventricular assist devices. For patients with anatomically small peripheral arteries or insufficient circulatory support, sternotomy and central cannulation techniques may be necessary. These invasive approaches are associated with increased risk of bleeding and other significant complications. We describe a minimally invasive, off-pump technique to provide adequate hemodynamic support and left ventricular unloading, allowing early postoperative ambulation, and ability to easily provide additional right ventricular/ECMO support if needed.
