While flow measurements help assess graft patency during surgery, there are limited tools available for surgeons to objectively evaluate myocardial perfusion after graft placement. Near-infrared fluorescence (NIRF) imaging shows promise in this area, offering real-time visualization of flow and perfusion without the need for radiation or nephrotoxic contrast agents.
