Pulmonary hypertension in pediatric heart transplantation
1University of Utah School of Medicine and Primary Children's Medical Center, Salt Lake City, UT, USA
Insights
Pediatric pulmonary hypertension complicates heart failure management and heart transplantation. Early recognition and management are crucial for successful outcomes in pediatric heart transplant candidates.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Surgery
- Pulmonology
Background:
- Pulmonary hypertension (PH) is a significant challenge in pediatric congestive heart failure (CHF).
- Accurate assessment of pulmonary artery (PA) anatomy, pressures, and pulmonary vascular resistance (PVR) is vital for heart transplant evaluation.
- Elevated PVR can contraindicate transplantation due to risks of right ventricular failure.
Purpose of the Study:
- To review the recognition, diagnosis, and management of PH in pediatric heart transplant candidates.
- To highlight the impact of PH on pre-operative and post-operative care.
- To inform clinical decision-making regarding transplantation in PH patients.
Main Methods:
- Literature review focusing on pediatric PH in the context of heart transplantation.
- Analysis of diagnostic criteria and management strategies.
- Synthesis of information on pre- and post-operative care considerations.
Main Results:
- Severe, fixed PH is a contraindication for heart transplantation.
- Even moderate PH can complicate post-transplant management.
- Comprehensive pre-transplant evaluation is essential.
Conclusions:
- Effective management of PH is critical for pediatric heart transplant recipients.
- Understanding PH is key to optimizing outcomes in this vulnerable population.
- This review provides a framework for managing PH in pediatric heart transplant candidates.
Abstract:
Pulmonary hypertension can pose a significant problem in the management of children with congestive heart failure. Assessment of pulmonary artery anatomy, pressures and (when possible) pulmonary vascular resistance is critically important in the evaluation of these children when they are under consideration for heart transplantation. Severe, fixed elevation of the pulmonary vascular resistance is a contraindication to heart transplantation because of concerns of acute post-transplant donor right ventricular failure. However, even modest degrees of pulmonary hypertension can complicate the post-operative management of pediatric heart transplant recipients. This review will provide information regarding the recognition, diagnosis, and pre-operative and post-operative management of pulmonary hypertension in patients under consideration for heart transplantation.
