Optical coherence tomography catheter for cardiac tissue imaging and characterization

總結

Catheter-based cardiac surgery has become routine in standard clinical practice, allowing clinicians to probe the interior of the heart without an intensive surgical procedure. Although electrical mapping and force-based catheters have been developed for cardiac applications, the ability to extract structural and functional information from the targeted tissue remains limited. Optical coherence tomography (OCT) is an established imaging modality that so far has largely been used for high-resolution imaging of the retina. The technology presented here is an OCT-based imaging catheter for structural analysis of cardiac tissue. By incorporating OCT technology into a clinical, catheter-based system, interventional cardiologists may be able to leverage the high resolution capabilities of OCT to perform screening for endomyocardial biopsy (EMB) or to monitor the formation of ablation lesions.
