简介：
Overview
This article presents a protocol for the noninvasive assessment of myocardial performance during normothermic ex situ heart perfusion. The method compares the epicardial echocardiography technique with the invasive pressure-volume loop technique for evaluating cardiac function.
Key Study Components
Area of Science
- Cardiology
- Heart Transplantation
- Noninvasive Assessment Techniques
Background
- Heart transplantation carries the risk of primary graft failure.
- Isolated ex situ perfusion is a critical phase for donor heart evaluation.
- Current methods for hemodynamic assessment are limited.
- Epicardial echocardiography may provide valuable insights during this process.
Purpose of Study
- To establish a reliable noninvasive method for assessing donor heart function.
- To compare the effectiveness of epicardial echocardiography and invasive techniques.
- To enhance the understanding of cardiac performance during ex situ heart perfusion.
Methods Used
- Epicardial echocardiography for noninvasive assessment.
- Invasive pressure-volume loop technique for comparison.
- Collaboration with a cardiologist trained in transoesophageal echocardiography.
- Evaluation of cardiac performance in working mode during isolated ex situ perfusion.
Main Results
- The protocol allows for effective assessment of myocardial performance.
- Epicardial echocardiography provides critical data before transplantation.
- Comparison with invasive techniques highlights its reliability.
- Team experience in ex situ heart perfusion is essential for success.
Conclusions
- The described protocol enhances the assessment of donor hearts.
- Noninvasive techniques can improve outcomes in heart transplantation.
- Further studies may validate the efficacy of this approach.
