The management of massive pulmonary embolism remains challenging, with a considerable mortality rate. Although veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for massive pulmonary embolism has been reported, its use as salvage therapy has been associated with poor outcomes. We reviewed our experience utilizing an aggressive, protocolized approach of VA-ECMO to triage, optimize, and treat these patients. ⋯ VA-ECMO appears to be an effective tool to optimize end-organ function as a bridge to recovery or intervention, with excellent outcomes. This approach may allow clinicians to better triage patients with massive pulmonary embolism to the appropriate therapy on the basis of recovery of RV function, residual thrombus burden, operative risk, and neurologic status.

The Nuss procedure is a minimally invasive surgery for pectus excavatum. Success of the Nuss procedure is dependent on a previously bent pectus bar that is shaped to the desired curvature of the chest wall. Traditionally, the size and curvature of the metallic pectus bar are determined by trial and error. Herein, we introduce a novel design method for the metallic pectus bar to optimize the bar curvature and outcome after the Nuss procedure. ⋯ Our initial results revealed that the 3D printed model-assisted Nuss procedure reduces the surgical duration and facilitates an optimal morphological outcome.
