Goal: Rotary blood pumps (RBPs) typically support the left ventricle by pumping blood from the ventricle to the aorta, partially bypassing the aortic valve (AV). Monitoring the AV opening during RBP support would provide important information about cardiac–pump interaction. However, currently this information is not continuously available. In this study, an algorithm to determine AV opening using...
Coronary Artery Bypass Graft (CABG) is the full name of bypass surgery method in coronary artery. There are two common bypass techniques which are individual technique and sequential technique. After bypass surgery, the bypass grafts seem to be obstructed in distal anastomosis between graft and host vessel. This obstruction in CABGs has been purposed as a factor from irregular hemodynamics, causing...
During left ventricular support by rotary blood pumps (RBPs), pump speed plays an important role in the amount of heart support. The reducing of pump speed seems important in order to prevent some adverse events in the heart valve. However, when pump speed was reduced, the backflow which is the flow that has the reverse direction to blood pumping direction may occur more easily. This is due to the...
