    Optical Coherence Tomography Angiography (OCTA) to Assess Cardiac Output and Cerebral Perfusion at the Time of Children's Cardiac Surgery

    Around 3500 children including 1,000 babies a year in the UK require heart surgery. Open-heart repairs involve the heart being stopped, while blood is pumped around the body using a cardiopulmonary bypass machine. Following complex operations, the patient may temporarily develop poor heart function, leading to reduced organ blood supply. Low heart output leads to post-operative complications or even death. The current methods to assess cardiac output and to see if vital organs, especially the brain, are receiving enough blood flow, are indirect and can be inaccurate. If we find a better way to detect and then avert or ...
