    "abstract": "Cardiogenic shock (CS) occurs infrequently in pregnancy and has a high mortality rate. Medical treatment options are few, with limited evidence of efficacy. Temporary mechanical circulatory supports (tMCS) may play a key role in addressing this therapeutic lacuna. We report successfully managing second-trimester CS using an Impella 5.5 micro-axial pump. Our patient presented in the second-trimester with CS. Hemodynamic parameters indicated biventricular dysfunction (low cardiac index, low pulmonary artery pulsatility index). She received diuresis and inotropic support to optimize her fluid status and cardiac function. However, failure to improve to the point where she would be able to tolerate the hemodynamic stresses of labor despite optimizing medical therapy prompted consideration of tMCS. The Impella 5.5 was chosen for its higher output (to maximize fetal perfusion), relative longevity, and lower hemolysis rates compared to other devices. It was used to support her from gestational weeks 28-30 and through the delivery. Support was continued for 4 weeks postpartum to allow for any potential cardiac recovery. Hope unrealized, a workup for destination therapy was initiated. Patient preference and high panel reactive antibodies informed the decision to pursue destination left ventricular assist device (LVAD) therapy. After a 3 month neonatal intensive care unit (NICU) stay, mother and baby were successfully discharged home.",
