Cardiac Bypass Surgery

The Kent Imaging device can measure the oxygen saturation of cardiac tissue during open heart surgery. The imaging device is quick and easy to use, providing visualization of oxygen delivery in less than a second. The technology makes it easy for medical professionals to identify perfusion deficits or changes in oxygen delivery before, during and after surgical intervention. Using the imaging may aid clinicians in evaluating the success of a graft during a coronary artery bypass graft (CABG) procedure and lead to better patient outcomes.

Below, a series of oxygenation images were taken showing perfusion of a pig heart where blood flow in the left anterior descending artery was manipulated during the sequence of multispectral images. The data generated suggests that the Kent Imaging device could be used to aid surgeons during coronary artery bypass surgery.

Perfusion is normal in the first and last images (left and right) of the sequence, while in the 2nd and 3rd images blood flow is reduced to 50% and 20%, respectively.
