[Multimodality imaging in the cardiac catheterization laboratory]

Area of Science:

• Cardiology
• Medical Imaging
• Interventional Cardiology

Background:

• Cardiac catheterization has significantly advanced congenital heart disease (CHD) management, evolving from diagnostic use to interventional procedures.
• Interventional cardiology techniques like PDA and ASD closure, pulmonary dilatation, and valve implantation have become crucial for treating CHD.
• The progress in interventional cardiology is closely linked to advancements in imaging technologies such as fluoroscopy, ultrasound, MRI, and CT.

Purpose of the Study:

• To explore the application and benefits of image fusion in cardiac catheterization.
• To enhance the visualization of cardiac structures, lesions, and devices for interventional cardiologists.

Main Methods:

• Image fusion involves superimposing multiple imaging modalities.
• Techniques include combining real-time fluoroscopy with offline slice imaging (MRI/CT).
• Simultaneous fusion of real-time fluoroscopy with ultrasound imaging is also employed.

Main Results:

• Image fusion aims to provide a more comprehensive view of the heart and surrounding structures.
• This integrated imaging approach assists interventional cardiologists in complex procedures.
• Improved visualization aids in accurate navigation and device placement during interventions.

Conclusions:

• Image fusion represents a significant development in cardiac catheterization.
• By integrating various imaging techniques, it enhances the understanding and management of congenital heart diseases.
• This technology supports interventional cardiologists in performing procedures more effectively.
