Survival After Cardiac Transplantation in Adults With Single-Ventricle Congenital Heart Disease
- Retrospective cohort study
- outcome-blinded investigators
- probability-linkage of National Inpatient Sample and OPTN data sets
Authors' conclusion
Among adult CHD transplant recipients, single-ventricle physiology correlated with higher short-term mortality. However, 10-year conditional survival was similar for biventricular and most single-ventricle CHD patients, and notably better for biventricular CHD patients compared to non-CHD heart transplant recipients.
Study context
- Population
- Adults (≥18 years) with congenital heart disease (CHD) undergoing heart transplantation, 2005–2020
- Participants
- 382 CHD recipients
- Exposure
- Single-ventricle vs biventricular CHD heart transplant recipients
- Single-ventriclen = 185
- Outcome
- Survival after heart transplantation
- Follow-up
- 1 and 10 years
