# First use of a new extended reality tool for preoperative planning in coronary artery bypass surgery: a case-report

## TL;DR

A new extended reality tool was used to help plan and perform a heart bypass surgery, improving precision and outcomes.

## Contribution

The first use of an AI-driven, extended reality tool for preoperative planning in CABG surgery is demonstrated.

## Key findings

- A patient-specific 3D coronary model was generated using an AI algorithm from CT angiography data.
- The extended reality tool improved spatial orientation and stenosis localization during surgery.
- The tool enhanced surgical planning and execution in CABG procedures.

## Abstract

A 73-year-old male presented with angina symptoms and was diagnosed with three-vessel coronary artery disease by use of computed tomography angiography and coronary angiography. This diagnosis necessitated coronary artery bypass grafting (CABG) surgery. A custom made AI-driven algorithm was used to generate a patient-specific three-dimensional coronary artery model from computed tomography angiography imaging data. This framework enabled precise segmentation and reconstruction of the coronary vasculature, yielding an accurate anatomical and pathological representation. Subsequently, this generated model was integrated into a novel extended reality tool for preoperative planning and intraoperative guidance in CABG surgery. Both preoperatively and intraoperatively, the tool augmented spatial orientation and facilitated precise stenosis localization, thereby enhancing the surgeon’s operative proficiency. This case report underscores the utility of advanced extended reality tools in cardiovascular surgery, emphasizing their pivotal role in refining surgical planning and execution.
