Example Sentences
The pump, a new type of ventricular assist device, or VAD, is surgically attached to the heart to augment its blood-pumping action in individuals with heart failure, allowing time to find a donor heart.
To treat patients who are experiencing cardiogenic shock, a percutaneous VAD can be inserted through the arteries until it is positioned across the aortic valve, where it helps to pump blood out of the left ventricle.
If doctors knew that the right heart would also need support, they could implant another VAD that helps the right ventricle.
A VAD was implanted in the left ventricle of each animal, and the researchers analyzed several different metrics of heart function as the pumping speed of the device was increased and decreased.
The researchers found that the most important factor in how the right ventricle responded to VAD implantation was how well the pulmonary vascular system -- the network of vessels that carries blood between the heart and lungs -- adapted to changes in blood volume and flow induced by the VAD.
