[사진=게티이미지뱅크]A robotic replica of the right ventricle of the heart has been developed that mimics the beating and blood pumping action of a living heart. According to a study published in Nature Cardiovascular Research, the robotic ventricle created by MIT researchers combines real heart tissue with balloon-like synthetic artificial muscles to control the ventricle while observing how natural valves and other complex structures work. It allows you to control contractions.
The right ventricle is one of the four chambers of the heart, along with the left ventricle, left atrium, and right atrium. The right ventricle is a thin muscle with complex structure and movement, making it difficult for medical staff to accurately observe and evaluate the function of the right ventricle in heart disease patients. “Existing tools often fail to capture the complex mechanisms and dynamics of the right ventricle, potentially leading to misdiagnosis and inappropriate treatment,” the researchers said.
Researchers designed a realistic functional model of the right ventricle to improve understanding of the little-known right ventricle and speed the development of cardiac devices to treat right ventricular dysfunction. This model includes real heart tissue.
The researchers found that the pumping capacity and function of the internal structures of the artificial ventricle model were similar to those previously observed in healthy living animals. This showed that this model can realistically simulate the function and anatomy of the right ventricle. The researchers were also able to adjust the frequency and output of the pumping tube to mimic various heart conditions, including irregular heartbeat, muscle weakness, and high blood pressure.
The artificial ventricle the researchers created can be adjusted to mimic both healthy and diseased states. The researchers manipulated the model to simulate conditions of right ventricular dysfunction, including pulmonary hypertension and myocardial infarction. They also used this model to test cardiac devices.
“The right ventricle is particularly vulnerable to dysfunction in the intensive care unit environment, especially in patients on mechanical ventilators,” the researchers said. “Robotic right ventricular simulators can be used to develop strategies to prevent right heart failure in these vulnerable patients.” “He said.
“We are reviving the heart in a way that allows us to study and potentially treat dysfunction,” he said. “Combining this with an artificial functional model of the left ventricle that we are currently fine-tuning, we hope to create a fully tunable artificial heart that can function in people.” “I’m imagining it,” he added.
