Answer

The patient becomes volume dependent to maintain adequate left and right ventricular filling. Occasionally, dobutamine may be needed, or even an intraaortic balloon pump for hemodynamic support.

Avoid nitrates or any medications that lower preload in this setting. A pulmonary artery catheter can be helpful in guiding therapy.
