Integrated x-ray and echocardiography imaging for structural heart interventions.

Area of Science:

• Cardiovascular Imaging
• Interventional Cardiology
• Medical Technology Innovation

Background:

• Percutaneous treatment of structural heart disease (SHD) is increasing but faces challenges.
• Current imaging modalities, primarily fluoroscopy, limit simultaneous visualization of anatomy and devices.
• 3D transesophageal echocardiography (TEE) offers soft tissue insights but visualization challenges persist.

Purpose of the Study:

• To address the limitations of visualizing cardiac anatomy and devices during percutaneous SHD interventions.
• To explore the potential of fusing live 3D TEE with live X-ray for improved procedural guidance.
• To enhance communication, confidence, and efficiency in SHD interventions.

Main Methods:

• Review of current imaging technologies for SHD interventions.
• Discussion of the challenges in visualizing soft tissue anatomy and device interaction.
• Proposal of an innovative imaging technology integrating live 3D TEE and live X-ray.

Main Results:

• Inability to simultaneously visualize anatomy and devices is a key difficulty in SHD interventions.
• 3D TEE provides valuable soft tissue anatomical information.
• Fusion of live 3D TEE and live X-ray is proposed as a solution to improve visualization and guidance.

Conclusions:

• Improved visualization is critical for the success of percutaneous SHD treatments.
• Integrated imaging technologies like fused live 3D TEE and X-ray can enhance operator confidence and anatomical awareness.
• This innovative approach has the potential to increase procedural efficiency and success rates in SHD interventions.
