Anomalous venoatrial connections - CT and MRI assessment

Area of Science:

• Cardiology
• Medical Imaging
• Pediatric Congenital Heart Disease

Background:

• Abnormal venous atrial (VA) connections are a significant challenge in pediatric congenital heart disease (CHD).
• Accurate anatomical evaluation is difficult during prenatal and perinatal periods but critical for surgical planning and patient outcomes.
• Echocardiography is the primary imaging tool for simple VA connections.

Purpose of the Study:

• To review the role of CT and MRI in evaluating complex abnormal VA connections over a decade.
• To illustrate challenging CHD cases and the utility of advanced imaging techniques.
• To discuss the impact of imaging on surgical strategy and outcomes for complex VA connections.

Main Methods:

• Retrospective analysis of abnormal VA connections investigated with CT and MRI from 2013-2022.
• Utilized 3D post-processing of volumetric CT and MRI data, including volume rendering (VR) and multiplanar reconstructions (MPR).
• Focused on complex cases and

Main Results:

• CT and MRI are essential for complex congenital heart disease and challenging VA connection cases.
• 3D post-processing aids in clarifying complex anatomical relationships.
• 3D printing models derived from CT/MRI data can customize surgical strategies.

Conclusions:

• Advanced imaging like CT and MRI, coupled with 3D post-processing, is vital for managing complex abnormal VA connections.
• These techniques improve anatomical understanding, surgical planning, and potentially patient outcomes.
• Addressing complex cardiovascular arrangements requires sophisticated imaging and tailored surgical solutions.
