Heart failure & cardiomyopathies
Predicted Heart Mass: A Tale of 2 Ventricles
Authors' conclusion
The association between donor-recipient PHM match and the risk of graft failure after heart transplantation can be further understood as risk attributable to LV undersizing and RV oversizing.
Study context
- Population
- Adult heart transplant recipients, UNOS database, 2000–2018
- Participants
- 34,976 recipients
- Exposure
- Separate left ventricular (LV) and right ventricular (RV) predicted heart mass (PHM) vs total PHM for donor-recipient size matching
- Outcome
- Graft failure
- Follow-up
- 1 year
