Area of Science:

Cardiovascular Surgery
Medical Technology
Surgical Navigation

Background:

Minimally invasive cardiac surgery (MICS) presents challenges due to limited operative field and exposure.
Effective preoperative planning and intraoperative visualization are critical for MICS success.

Purpose of the Study:

To evaluate the initial experience of using HoloLens® 2 as an intraoperative guide in MICS procedures.
To assess the utility of mixed reality (MR) for surgical planning and real-time image guidance.

Main Methods:

Three-dimensional (3D) patient CT data were rendered into holograms on HoloLens® 2.
Holographic images were superimposed onto patients for real-time anatomical guidance during aortic valve replacement, coronary artery bypass graft, and pulmonary valve replacement surgeries.
Incision sites were marked using HoloLens® 2 and compared to conventional methods.

Main Results:

HoloLens® 2 guided incision marking resulted in a more appropriate entry site compared to conventional methods.
The device provided an unobstructed view of the surgical field.
The superimposed holographic image facilitated understanding of anatomical relationships.

Conclusions:

HoloLens® 2 can serve as an effective intraoperative guide in MICS.
Mixed reality technology has the potential to enhance surgical precision, reduce risks, and improve patient safety in cardiac surgery.
