Use of a Single-Circuit CentriMag® for Biventricular Support in Postpartum Cardiomyopathy

Peripartum cardiomyopathy (PPCM) is defined by acute heart failure in the late stages of pregnancy to a few months postpartum. Cardiogenic shock in PPCM, though rare, can be life-threatening, often requiring support with mechanical circulatory support devices. We present a case of 37-year-old Caucasian female who developed cardiogenic shock within 24 hours of the delivery of her twins. The echocardiogram demonstrated severe biventricular failure which necessitated biventricular device placement and support with a CentriMag® centrifugal pump. This biventricular support was employed, using a single-circuit CentriMag® pump, using a ‘Y’ connection which made weaning from right-sided support and conversion to univentricular support easier and feasible. The patient recovered four weeks later and was explanted off the CentriMag® support and did well. This technology allows for the CentriMag® to be considered as an early option for biventricular support in the treatment and management of these patients as a bridge to recovery.
