A cavalpulmonary assist device utilising impedance pumping enhanced by peristaltic effect (2024)
Journal Article
Burns-Cox, A., Gan, L., & Khir, A. (2024). A cavalpulmonary assist device utilising impedance pumping enhanced by peristaltic effect. The International Journal of Artificial Organs, 47(10), 765-773. https://doi.org/10.1177/03913988241268419

Background: Fontan procedure, the standard surgical palliation to treat children with single ventricular defects, causes systemic complications over years due to lack of pumping at cavopulmonary junction. A device developed specifically for cavopulmo... Read More about A cavalpulmonary assist device utilising impedance pumping enhanced by peristaltic effect.

Synthesis of Multimodal Cardiological Signals Using a Conditional Wasserstein Generative Adversarial Network (2024)
Journal Article
Cretu, I., Tindale, A., Balachandran, W., Abbod, M., William Khir, A., & Meng, H. (2024). Synthesis of Multimodal Cardiological Signals Using a Conditional Wasserstein Generative Adversarial Network. IEEE Access, 12, 133994-134007. https://doi.org/10.1109/access.2024.3449134

Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. Recent advancements in machine learning have significantly enhanced early detection and treatment strategies for CVDs. While electrocardiogram (ECG) signals are commonly use... Read More about Synthesis of Multimodal Cardiological Signals Using a Conditional Wasserstein Generative Adversarial Network.

Manufacturing an Artificial Arterial Tree Using 3D printing (2024)
Journal Article
Hacham, W. S., & Khir, A. W. (2024). Manufacturing an Artificial Arterial Tree Using 3D printing. Heliyon, 10(11), Article e31764. https://doi.org/10.1016/j.heliyon.2024.e31764

Models of the arterial network are useful in studying mechanical cardiac assist devices as well as complex pathological states that are difficult to investigate in-vivo otherwise. Earlier work of artificial arterial tree (AAT) have... Read More about Manufacturing an Artificial Arterial Tree Using 3D printing.

A comparison of different methods to maximise signal extraction when using central venous pressure to optimise atrioventricular delay after cardiac surgery. (2024)
Journal Article
Cretu, I., Tindale, A., Abbod, M., Balachandran, W., Khir, A. W., & Meng, H. (2024). A comparison of different methods to maximise signal extraction when using central venous pressure to optimise atrioventricular delay after cardiac surgery. International Journal of Cardiology, 51, Article 101382. https://doi.org/10.1016/j.ijcha.2024.101382

Our group has shown that central venous pressure (CVP) can optimise atrioventricular (AV) delay in temporary pacing (TP) after cardiac surgery. However, the signal-to-noise ratio (SNR) is influenced both by the methods used to mitigate the pressure e...
