This week we review a recent important work on outcomes of pregnancy in patients with bioprosthetic valves. What percentage of women entering pregnancy have a dysfunctional bioprosthetic valve? Is there a particular position of valve where the risk of dysfunction is greater for cardiac or fetal events? We speak with noted cardio-obstetrical expert, Dr. Barbara Wichert-Schmitt of Johannes Kepler University in Linz, Austria about her recent work from Canada. doi: 10.1016/j.jacc.2022.09.019
