Better treatment through optical heart movement sensing during open cardiac surgery
CardiomeDIC™ supports clinicians’ decision-making with non-invasive optical movement sensing and deformation analysis of the heart during open heart surgery.
Demand and Benefit
At present, visual examination is one of the key diagnostic means when assessing the condition and filling of the right ventricle during open heart surgery.
The disadvantage of this routine is that it is prone to cognitive biases, it relies strongly on the surgeon’s
experience and memory and it does not provide recordable parameters to be entered in the patient’s surgery protocol.
CardiomeDIC™ compensates for these shortcomings by providing quantifiable data from digital image analysis in a way suitable for the medical context.
Lights up hearts
cardiomeDIC helps heart surgeons to achieve better results in open heart surgery and delivers new information about the functioning of the heart. The functioning of the right side of the heart cannot be reliably measured and quantified during the heart surgery by any current technological method, even though it is a well-known fact that any problems associated with the functioning of the right ventricle can have serious complications. Following the current state of the art, the function of the heart is evaluated using an ultrasonic sensor placed in the esophagus of the patient. This sensor provides information about the function of the left ventricle, but it has only limited feasibility in describing the deformation and motion of the right ventricle and atrium. The walls of the right ventricle are very thin compared to the left ventricle, whilst at the same time the heart is lifted up with cardiac sack during surgery, making contact non-optimal. Therefore, ultrasound technology has shortcomings in focusing on the right side of the heart. Furthermore, everyone who has seen an ultrasound image knows that they typically are of fairly low quality and require a lot of user expertise and experience for correct interpretation. Because of this, visual inspection by the operating surgeons is currently the best practice to evaluate the condition and functioning of the right ventricle and atrium. The accuracy obviously depends on the experience and skills of the surgeon, and is prone to cognitive bias.
cardiomeDIC technology offers solutions to these shortcomings by providing the operating team high quality measurement data describing the functioning of the right ventricle and atria. The data obtained with our solution is neither user nor user experience dependent, which brings about improvements in usability, reliability, repeatability and allows for better comparison of results. The measurements are based on optical imaging, and are therefore both contact free and free of any hazardous radiation. The description of the functioning of the heart, on the other hand, is based on deformation analysis and provides a quantitative description of the right heart. Results can be visualized in various ways as required by the situation. One significant benefit is the ability to compare the functioning of the heart at different stages during the operation, which typically lasts for several hours. The video below illustrates the capabilities of the technology and visualizes what the final product could look like.
The commercialization of the research results is funded by the TEKES New Knowledge and Business from Research Ideas program. The project is carried out in collaboration with Tampere University Hospital Heart Center. The academic and applied research, partly supporting the commercialization, is funded by the Foundation of Jane and Aatos Erkko.
