Background

3D Holograms are an emerging tool for intuitively manipulating and visualizing CT images. However, measurements with 3D holographic images have not been validated. The new CanaLife Holo software offers a function to measure the length of objects in 3D spaces. In the current study, we aimed to assess the feasibility and accuracy of using CT holograms for bypass graft length measurement.

Methods

Twenty consecutive cases in theFAST TRACK CABG trial were included. The post-operative CT images performed at30 days follow-up were analyzed in an independent core lab. Analysts blinded toclinical information performed Holographic reconstruction and measurement usingthe CanaLife Holo software (Medapp, Krakow, Poland). (Figure panel A) Anotheranalyst with full access to clinical information performed the validationmeasurements on the CardIQ W8 system (GE Healthcare, Milwaukee, Wisconsin). (Figurepanel B)

Results

A total of 47 grafts (20 leftinternal mammary artery grafts, 19 saphenous vein grafts, and 8 right internalmammary artery grafts) were measured. On average, holographic reconstructionand measurement of a case took 3 minutes and 36 seconds± 49.45seconds as compared with around10 minutes per vessel on the traditional CT system. There was no significantdifference between the graft length measured by hologram and CT (190.38±55.62mmvs. 185.85±55.19mm,p=0.958). The measurements of hologram and CT are highly correlated (r=0.99,p<0.01) with good agreement. (Figure panel C, D)

Conclusion

Holographic vessel length measurementis feasible, fast, and accurate even for tortuous coronary bypass grafts. This newmethodology can empower surgeons to visualize and measure the results of their workby themselves and may provide insights to for procedure evaluation.
