In CAD patients from the post-percutaneous coronary intervention era the presence of collaterals reduced mortality by 0.47 (p < 0.0001) and deaths and re-infarctions by 0.54 (p < 0.0001).
VA ECMO can be employed successfully in obstetric patients with cardiogenic shock with appropriate patient selection. Further research is needed to determine if VA ECMO provides a survival advantage over traditional management strategies in this vulnerable population.
