This is the third episode of a special podcast series on obstetric critical care.  Although I am the sole host of this podcast, the content was reviewed and edited by Dr. Elizabeth Garchar, MD, FACOG.  She is an OB/GYN and Maternal Fetal Medicine (MFM) specialist who has a particular interest in obstetric critical care.  She is also unique in that she flies regularly with our critical care transport teams and acts as one of our Assistant Medical Directors for the flight program.  So, Dr. Garchar has unique insight into managing this population in transport. The topic of this podcast is peripartum cardiomyopathy.  Acquired cardiac conditions in otherwise healthy pregnant patients can be a serious and life-threatening condition.  Sometimes, critical care transport crews are called to transport pregnant or recently postpartum females with severe, acquired cardiomyopathy or in frank cardiogenic shock.  This podcast reviews the presentation, underlying pathophysiology, and management of this patient population.   References  1.          Arany Z, Elkayam U.
