Intracoronary optical frequency domain imaging: which one is the best? Insights from the PERFECTO study

Introduction:

Swept source Fourier domain optical coherence tomography, also known as the optical frequency domain imaging (OFDI), is a key tool for intracoronary assessment. The aim of the study was to determine whether there was a difference in terms of artefacts and image quality during a pullback process between ABBOTT (using the DragonFly OPTIS® catheter) and TERUMO (using the FastView® catheter).

Materials and methods:

The design was a historical multicentric cohort study with retrospective data analysis extracted from the PERFECTO study, from March 2018 to January 2020. Motion artefact, residual blood artefact and technical specifications were collected and evaluated by a single proofreader in open label.

Results:

Ninety-three patients from the PERFECTO study were included. An OFDI control was performed at J0 and at 3 months after percutaneous coronary intervention (PCI), resulting in a total of 338 pullbacks since a control could imply one or more pullbacks. The pullbacks were divided into two groups based on the catheter used during the PERFECTO study (ABBOTT n=61, TERUMO n=277). There was no statistically significant difference in the proportion of artefacted frames per pullback between ABBOTT and TERUMO (20% vs 18%; p = 0.81), and in terms of pullback image quality (85% vs 89%, p = 0.37). The studied artery length was greater in TERUMO group (54 vs 74mm; p <0,001).

Conclusion:

Both medical devices seem to be similar in terms of artefacts and image quality of pullback. However, TERUMO provides higher artery length, which could have clinical implications.
