Passive control of a biventricular assist device with compliant inflow cannulae.
Rotary ventricular assist device (VAD) support of the cardiovascular system is susceptible to suction events due to the limited preload sensitivity of these devices. This may be of particular concern with rotary biventricular support (BiVAD) where the native, flow balancing Starling response is diminished in both ventricles. The reliability of sensor and sensorless-based control systems which a...
متن کاملDynamic left ventricular assist device inflow obstruction.
A 72-year-old man with a history of rheumatic heart disease , prior bioprosthetic mitral and aortic valve replacement , severe nonischemic dilated cardiomyopathy (left ventricular [LV] ejection fraction 5%), and a history of ven-tricular tachycardia (VT) underwent implantation of a continuous flow LV assist device (LVAD; HeartMate II; Thoratec Corporation) as destination therapy for severe hear...
متن کاملCardiac Failure after Liver Transplantation Requiring a Biventricular Assist Device
Increased hepatic iron load in extrahepatic organs of cirrhotic patients with and without hereditary hemochromatosis portends a poorer long term prognosis after liver transplant. Hepatic as well as nonhepatic iron overload is associated with increased infectious and postoperative complications, including cardiac dysfunction. In this case report, we describe a cirrhotic patient with alpha 1 anti...
متن کاملOxygenation via a Biventricular Assist Device for Emergency Airway Management.
A 56-year-old man receiving mechanical circulatory support via a biventricular assist device suffered an airway emergency secondary to bleeding into the airway. An improvised solution to gain control of the airway in the short term was devised, and an oxygenator was inserted into the circuit, providing an alternative means of gas exchange while definitive control of the airway was achieved. Thi...
متن کاملA Case of Wide Complex Tachycardia in a Patient with a Biventricular Assist Device.
This case report highlights the variety of wide complex tachycardias, and the need for their prompt management, in the growing population of patients with circulatory support devices. We present a case that demonstrates how a wide complex supraventricular tachycardia in a patient with a biventricular assist device can be safely and effectively targeted for treatment using percutaneous radiofreq...
