Brief summary
This research project is investigating how a right ventricular strain, also known as deformation, obtained during trans-oesophageal echocardiography, may be used to predict kidney failure in patients who are placed on cardiopulmonary bypass for heart and lung surgery. Right ventricular strain may be calculated from echocardiographic images, already taken during heart surgery. Trans-oesophageal ultrasound is an established bedside ultrasound investigation that is used on most patients having heart and lung surgery. Recent technological advancements have allowed us to look at the heart in more detail with the aim of improving the outcomes of these patients. Kidney failure is a major problem after heart and lung surgery and increases post-operative mortality. It also results in longer hospital stays, invasive investigations, invasive treatments, and may result in the patient needing long term dialysis and transplantation. Our understanding of how right ventricular strain relates to kidney dysfunction is currently very poor. This research project will improve our understanding and our aim is that this will enable us to direct treatments to preserve kidney function in at risk patients and improve the burden of kidney failure on the patients affected and on the hospitals taking care of them.
Interventions
This study is a retrospective analysis of previously captured echocardiographic images of the right ventricle obtained from peri-operative trans-oesophageal echocardiography at the completion of cardiothoracic surgery once patients have been separated from cardiopulmonary bypass. These images are used to determine a numerical value for right ventricular strain. The source of images is from the database of trans-oesophageal echocardiography images obtained as part of the normal care of patients

These images are used to determine a numerical value for right ventricular strain. The source of images is from the database of trans-oesophageal echocardiography images obtained as part of the normal care of patients that have undergone cardiac surgery requiring cardiopulmonary bypass at Fiona Stanley Hospital, Perth, WA, Australia between 3rd February 2020 to 3rd August 2020.
