Performing a myocardial biopsy in a cardiac transplant patient with a persistent left superior vena cava

Area of Science:

• Cardiology
• Transplant Medicine
• Congenital Heart Disease

Background:

• Increasing life expectancy for congenital heart disease (CHD) patients leads to a growing adult population with these conditions.
• Invasive cardiologists require enhanced knowledge of complex congenital heart defect anatomy for optimal patient management.
• Adult congenital heart disease (ACHD) prevalence necessitates advanced procedural skills in interventional cardiology.

Observation:

• A case involving a cardiac transplant recipient with multiple congenital heart defects, including a persistent left superior vena cava (PLSVC), is presented.
• The patient underwent a right heart catheterization procedure.
• A myocardial biopsy was successfully performed during the procedure.

Findings:

• Right heart catheterization was feasible and informative in this complex ACHD patient post-transplant.
• Myocardial biopsy provided crucial diagnostic information in the context of transplanted heart management.
• The presence of a persistent left superior vena cava did not preclude successful cardiac catheterization.

Implications:

• This case underscores the importance of understanding complex CHD anatomy for invasive cardiologists managing adult patients.
• Expertise in ACHD is crucial for performing procedures like right heart catheterization and myocardial biopsy in specialized populations.
• Successful management strategies for ACHD patients, including those with PLSVC and post-transplant status, can be enhanced through case-based learning.
