Summary
Orthotopic heart transplant recipients with a weight mismatch (recipient heavier than donor) and no prior cardiac surgery face higher risks of pericardial effusion. This finding aids in identifying at-risk patients for closer monitoring.
Area of Science:
- Cardiology
- Transplantation Medicine
- Surgical Outcomes
Background:
- Pericardial effusions are common post-orthotopic heart transplantation (OHT), but risk factors remain poorly understood.
- Previous studies suggested rejection or cyclosporine, but anatomical factors were not investigated.
Purpose of the Study:
- To identify etiological factors contributing to significant pericardial effusion after OHT.
- To assess the impact of pericardial effusion on patient survival post-transplantation.
Main Methods:
- Retrospective review of 203 OHT patients' medical records and echocardiograms.
- Analysis included ischemic time, rejection severity, donor-recipient weight difference, and prior cardiac surgery history.
- Multivariate analysis and Kaplan-Meier survival curves were employed.
Main Results:
- 8.9% of patients developed moderate to large pericardial effusions, with 44% requiring pericardiocentesis.
- Recipient weight > donor weight and lack of prior median sternotomy were strong predictors of effusion.
- No significant association was found between effusions and rejection or survival rates.
Conclusions:
- Positive weight mismatch and absence of previous cardiac surgery are linked to significant pericardial effusion formation post-OHT.
- Increased surveillance for high-risk patients may be beneficial.
