Indications for heart transplantation in congenital heart disease

Area of Science:

• Cardiology
• Transplantation Medicine
• Congenital Heart Disease

Background:

• Congenital heart disease (CHD) represents a complex challenge in end-stage heart failure management.
• Cardiac transplantation is an established, yet intricate, treatment strategy for select CHD patients.
• Patient heterogeneity in CHD necessitates individualized approaches to transplantation.

Purpose of the Study:

• To review indications for cardiac transplantation in patients with congenital heart disease.
• To discuss the principles of transplant as a primary or secondary intervention.
• To highlight the importance of referral timing, evaluation, and complication management.

Main Methods:

• Literature review focusing on cardiac transplantation in CHD.
• Analysis of general principles, referral timing, and patient evaluation.
• Discussion of prognostic indicators and suitability for listing.

Main Results:

• Patient referral timing and evaluation methods differ between CHD and other heart failure etiologies.
• Complications in CHD transplant candidates require specialized team management.
• Risk stratification is crucial, as not all CHD patients face uniform high transplant risk; failing Fontan circulations carry higher morbidity than failing Mustard circulations.

Conclusions:

• Standardizing transplant timing in heterogeneous CHD populations is challenging.
• Investigations like BNP, 6-minute walk, and exercise testing have roles and limitations in assessing CHD transplant candidates.
• Addressing the organ donor shortage is critical for meeting the growing demand for cardiac transplants in diverse CHD pathologies.
