Photoacoustic imaging for guidance of interventions in cardiovascular medicine

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Cardiovascular Interventions

Background:

• Minimally invasive interventions are crucial for treating cardiac disorders like coronary artery disease.
• Changes in vasculature and cardiac tissue composition are key indicators of cardiovascular disease.
• Current imaging modalities have limitations in providing detailed tissue information during interventions.

Purpose of the Study:

• To review state-of-the-art photoacoustic imaging techniques for cardiovascular intervention guidance.
• To assess the potential of photoacoustic imaging in detecting disease-related tissue changes.
• To provide an outlook on the clinical translation of these preclinical technologies.

Main Methods:

• Literature review of preclinical photoacoustic imaging studies.
• Analysis of techniques applicable to catheter-based cardiovascular interventions.
• Evaluation of image contrast mechanisms related to vascular and tissue composition.

Main Results:

• Photoacoustic imaging can visualize vasculature and tissue composition with high contrast.
• Several photoacoustic approaches show potential for real-time guidance during cardiovascular procedures.
• All reviewed techniques are currently in the preclinical development stage.

Conclusions:

• Photoacoustic imaging offers a promising non-invasive modality for guiding cardiovascular interventions.
• Further research and development are needed to translate these preclinical findings into clinical practice.
• Successful clinical application could enhance procedural success rates and patient outcomes in cardiology.
