Heart transplantation in adults with congenital heart disease

Area of Science:

• Cardiology
• Transplantation Medicine
• Congenital Heart Disease (CHD)

Background:

• Heart transplantation is an effective therapy for end-stage congenital heart disease (CHD) due to improved surgical techniques and patient selection.
• Indications for heart transplantation in CHD patients align with those for other forms of heart failure.

Purpose of the Study:

• To summarize the current understanding of heart transplantation in adult patients with congenital heart disease (CHD).
• To highlight key considerations in pretransplant assessment and outcomes for CHD patients undergoing heart transplantation.

Main Methods:

• Review of current literature and clinical practices regarding heart transplantation in adult CHD.
• Analysis of factors influencing pretransplant assessment, waitlist experience, and post-transplant survival.

Main Results:

• Pretransplant assessment for CHD patients requires thorough evaluation of cardiac anatomy, pulmonary vascular disease, allosensitization, hepatic dysfunction, and neuropsychiatric status.
• CHD patients face longer waitlist times and higher mortality while awaiting transplantation compared to other candidates.
• While CHD recipients have higher early mortality, they demonstrate a slight actuarial survival advantage by 10 years post-transplant.

Conclusions:

• Heart transplantation is a viable and increasingly utilized treatment for adults with end-stage CHD.
• Careful pretransplant evaluation is critical for optimizing outcomes in this complex patient population.
• Long-term survival data suggest a favorable outlook for CHD patients who successfully undergo heart transplantation.
