References This particular case presented cardiogenic shock, fluid overloaded, with a recent cardiac arrest that required the use of venous arterial ECLS. It was very difficult to determine whether the pulmonary hypertension was severe enough to contraindicate the heart transplantation. Therefore, a bridge to candidacy strategy seemed reasonable in this regard. After six months of support, it proved to be effective in reducing the pulmonary vascular resistance making the patient eligible for heart transplantation.
