Patient Perceptions and Knowledge Surrounding Pregnancy After Heart Transplantation: A Multicenter Study.

Background: More women of childbearing age are surviving after heart transplantation (HT), many of whom have a desire to become pregnant. Limited data exist evaluating patients' perspectives, receipt of counseling, and knowledge surrounding contraception, pregnancy, breastfeeding, and medication safety after HT.

Methods: We conducted a voluntary, confidential, web-based cross-sectional survey of women who were childbearing age (defined as 18-45 years) at the time of HT. Transplants occurred between January 2005 and January 2020. Surveys were conducted across 6 high-volume HT centers in the United States.

Results: There were 64 responses from women who were of childbearing age at the time of HT. Twenty-five women (39.1%) were pregnant before HT, and 6 (9.4%) women reported at least 1 pregnancy post-transplant. Fifty-three percent (n=34) reported they did not receive enough information on post-HT pregnancy before listing for HT, and 26% (n=16) did not discuss their ability to become pregnant with their care team before proceeding with HT. Following HT, 44% (n=28) still felt that they had not received enough information regarding pregnancy. The majority of women (n=49, 77%) had discussed contraception to prevent unplanned pregnancy with their transplant team. Twenty percent (n=13) reported that pregnancy was never safe after transplantation based on the information they had received from their transplant providers.

Conclusions: Many women feel they are not receiving adequate counseling with regard to posttransplant reproductive health. This survey highlights an opportunity to improve both provider education and patient communication to better support women with HT desiring posttransplant pregnancy.
