Donor heart quality control. Analysis of echocardiographic (EC) findings and patient outcome
Insights
Echocardiography (EC) screening identified significant donor heart abnormalities missed by conventional methods, improving graft viability. This enhances donor heart selection, reducing primary graft nonfunction and avoiding unnecessary surgical team transport.
Area of Science:
- Cardiology
- Transplantation Medicine
- Medical Imaging
Background:
- Donor heart selection relies on conventional clinical parameters.
- Limitations exist in current screening methods for detecting occult cardiac dysfunction.
Purpose of the Study:
- To evaluate echocardiography (EC) as an additional screening tool for donor heart selection.
- To assess the impact of EC screening on donor heart quality and transplant outcomes.
Main Methods:
- Retrospective analysis of 149 donor heart evaluations.
- Comparison of echocardiographic findings with conventional clinical parameters.
- Assessment of primary graft nonfunction rates in EC-screened hearts.
Main Results:
- 12% of donor hearts showed severe ventricular impairment or morphological abnormalities via EC.
- Nearly 50% of EC-detected pathological findings were missed by conventional screening.
- The primary graft nonfunction rate was 3.1% for EC-screened donor hearts.
Conclusions:
- Echocardiography provides crucial dynamic and morphological information for donor heart assessment.
- EC screening can identify occult cardiac dysfunction, potentially saving viable donors.
- Utilizing EC may prevent severe complications and reduce logistical costs associated with donor heart transplantation.
Abstract:
In a retrospective analysis, 149 echocardiographic (EC) evaluations were compared with conventional clinical parameters for donor heart selection. Of these cases, 12% were found with severe impairment of ventricular wall motion or with morphological abnormalities. Nearly half of the echocardiographically diagnosed pathological findings in donor hearts were not detected by conventional standards for heart screening. Analysis of EC-screened donor heart outcome showed a primary graft nonfunction rate of 3.1%. We suggest EC as an additional screening instrument for further dynamic and morphological information about donor heart condition. Potential donors can be saved for transplantation and severe complications can be avoided by detecting occult cardiac dysfunction. Early detection of cardiac dysfunction may have an impact on donor therapy and can avoid unnecessary and expensive transportation of the surgical team to the harvest site.
