Abstract
- This clinical image vignette describes the inadvertent placement of a balloon pump in the vena cava during a "code blue" scenario, and the lessons to be learned from that experience. The hemodynamic benefits of intra-aortic balloon pump during experimental cardiac arrest include shorter circulation time and increases in end-tidal CO2 and coronary perfusion pressure. However, the hemodynamic effects of venous diastolic augmentation during experimental cardiogenic shock vary, being detrimental in cases of low preload, and possibly beneficial in a high preload state. When performed emergently at the bedside, inadvertent intra-caval placement of a balloon pump can occur due to elevated venous pressures, in the presence of severe tricuspid regurgitation, or through an arteriovenous fistula. A similar radiographic appearance can also be seen in the presence of a right-sided aortic arch. Clues to improper position include an abnormal pressure waveform and the absence of hemodynamic changes or blood pressure augmentation.
