Complex adult congenital heart disease on cross-sectional imaging: an introductory overview

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Congenital heart disease (CHD) is the most common congenital pathology.
• Surgical advances have increased the adult population with repaired complex CHD.
• Adults with repaired CHD now represent a significant source of clinical morbidity, often requiring repeat interventions.

Purpose of the Study:

• To provide radiologists with an introductory overview of complex adult congenital heart disease.
• To familiarize non-specialist radiologists with post-operative anatomy, surgical management, and potential complications.
• To guide the use of CT and MRI in managing adult CHD patients.

Main Methods:

• Review of common complex congenital heart conditions and their surgical repairs.
• Discussion of CT and MRI protocols for imaging adult CHD.
• Analysis of CT/MRI findings for various complications in adult CHD patients.

Main Results:

• Adult patients with repaired complex CHD present unique diagnostic challenges.
• CT and MRI are essential for identifying hemodynamic pathophysiology and complications.
• Imaging findings correlate with specific post-operative anatomies and potential adverse events.

Conclusions:

• Radiologists require specialized knowledge to manage adult CHD patients effectively.
• Standardized CT/MRI protocols are vital for accurate diagnosis and timely intervention.
• This review serves as an educational resource for improving care in adult CHD.
