The Crashing Cardiac Transplant Patient
- Approximately 2000 patients receive a cardiac transplant each year in the United States.
- With improvements in surgical techniques, immunosuppression, and management of complications, graft half-life is now approximately 13 years; thereby increasing the likelihood that a cardiac transplant patient will show up in your ED.
- In the crashing cardiac transplant patient, think of the following causes for acute decompensation:
- Acute rejection
- Primary graft failure
- RV failure
- Sepsis
- For patients with primary graft failure initiate inotropic support with dobutamine, epinephrine, milrinone, or isoproteronol. Those failing standard inotropes will likely require mechanical circulatory support (VAD) or ECMO.
- Patients with acute RV failure will often require the combination of a pulmonary vasodilator (inhaled NO, prostaglandins) and inotropic agent. In addition, it is critical to avoid hypercapnia and hypoxia.
