Left Ventricular Assist Devices and Pregnancy: Systematic Review of Existing Literature and Case Report.

ABSTRACT

Although pregnancy is generally contraindicated in advanced heart failure (AHF), successful pregnancies have been observed in patients with left ventricular assist devices (LVADs). The number of pregnancies in patients with LVADs is increasing, yet optimal management strategies remain undefined. Additionally, no successful pregnancies have been reported with the HeartMate 3 (HM3) (Abbott) LVAD. A systematic review of pregnancy in patients with LVADs was prepared utilizing 3 major scientific databases. We also present the first reported case of successful pregnancy and delivery in a patient supported by an HM3 LVAD. The systematic search yielded 95 results. After filtering to include only relevant citations, eight unique cases were identified. Cases were compared on the basis of several clinical factors. Although pregnancies supported by LVADs are medically complex, several cases of successful deliveries have been observed. Clinical management between cases, however, did vary significantly. Several areas requiring further study were identified.
