Biological aortic valves linked to better pregnancy outcomes, but more reoperations

MedicalXpress | Jul 03, 2026

In cases of serious aortic valve disease, choosing a new heart valve is particularly difficult for young women who wish to become pregnant. A new Swedish registry study from Karolinska Institutet shows that a biological aortic valve provides good pregnancy and birth outcomes, even though the need for reoperation is more common than with a mechanical valve. The study is published in the JACC.
