Background: Prior exposure to cardiotoxic cancer therapies has been associated with an increased risk of peripartum cardiomyopathy (PPCM). The management of PPCM in this population remains a clinical challenge. Few studies have explored the use of mechanical circulatory support in PPCM. We present a case of early implementation of intra-aortic balloon pump (IABP) therapy for acute stabilization and intrapartum support of PPCM. Case summary: A 36-year-old G4P2103 (4th pregnancy, two full-term, one premature birth, 0 abortions, and three living children) woman at 26 weeks and 5 days gestation with history of combined peripartum and anthracycline-induced cardiomyopathy [previously left ventricular ejection fraction (LVEF) 10-15% and recently 40-45%] presented with acute decompensated heart failure. Her clinical status deteriorated with a drop in LVEF to 15-20% with a significant increase in pulmonary pressures and worsening mitral regurgitation. A multidisciplinary decision with the cardio-obstetrics team was made to place a pulmonary artery catheter for invasive haemodynamic monitoring and IABP insertion prior to delivery. Intra-aortic balloon pump support had a profound immediate decrease in her systemic and pulmonary vascular resistance allowing for a successful repeat caesarean delivery. Her haemodynamics remained stable after IABP removal and pulmonary pressures improved. She was discharged one week following her delivery on guideline-directed medical therapy. Discussion: O...
