What is ascending aortic banding?
Ascending aortic banding is a surgical procedure that involves constricting the aorta to study the effects on cardiac function.
Why use swine for this model?
Swine are more similar to humans in terms of cardiovascular anatomy and physiology, making them suitable for translational research.
What are the advantages of minimally invasive procedures?
Minimally invasive procedures reduce recovery time, minimize pain, and improve animal welfare while allowing for effective research.
How is pressure monitored during the procedure?
High-fidelity pressure sensors are used to monitor the pressure gradient in real-time during the surgical procedure.
What are the implications of this research?
This research can lead to better understanding and treatment of cardiac diseases in humans by providing more relevant preclinical models.
