Hybrid Imaging During Transcatheter Structural Heart Interventions.

Area of Science:

• Cardiovascular Imaging
• Medical Technology
• Interventional Cardiology

Background:

• Fusion imaging is increasingly popular for visualizing complex 3D cardiac structures.
• Most current fusion techniques use static images, limiting dynamic assessment.
• High-temporal and spatial resolution are crucial for imaging the beating heart.

Approach:

• This review focuses on real-time image fusion using transesophageal echocardiography and fluoroscopy.
• The approach involves real-time image overlay and marker use for enhanced visualization.
• The benefits of fusion imaging in structural heart disease (SHD) interventions are highlighted.

Key Points:

• Real-time fusion imaging is essential for complex interventions like transseptal puncture and valve procedures.
• Fusion imaging improves communication among structural heart disease teams.
• It potentially increases procedural success rates while reducing radiation exposure and contrast agent use.

Conclusions:

• Fusion imaging, particularly with echocardiography and fluoroscopy, offers significant advantages in SHD interventions.
• Further evidence is needed to confirm the impact of fusion imaging on safety and patient outcomes.
• This technique supports interventions on atrial septal defects, left atrial appendage, mitral, and aortic valves.
