Single ventricle hearts palliated with the Fontan operation present complications later in life as a result of increased venous pressures and abnormal ventricle function. Wave intensity analysis uses measurements of blood velocity and pressure to rep

Wave intensity analysis (WIA) as a framework to assess cardiovascular hemodynamics has been successfully used in many clinical applications. Typically, wave intensity calculations require the simultaneous acquisition of blood velocity and blood press

Changing the speed of left ventricular assist devices (LVADs) cyclically may be useful to restore aortic pulsatility; however, the effects of this pulsation on right ventricular (RV) function are unknown. This study investigates the effects of direct

The energy systems of mechanical circulatory support devices have evolved significantly since the inception of the Artificial Heart Program in 1963. The transition from bulky paracorporeal pulsatile blood pumps to continuous flow devices has facilita

The current generation of left ventricular assist devices (LVADs) provides continuous flow and has the capacity to reduce aortic pulsatility, which may be related to a range of complications associated with these devices. Pulsed LVAD operation using

Heart failure (HF) affects approximately 12,000-35,000 children each year in the United States. The development of blood pumps has provided circulatory support for many adults suffering with HF until they receive a heart transplant. However, while th

Right ventricular (RV) dysfunction has limited the effectiveness of mechanical circulatory support (MCS) therapy in some heart failure (HF) patients. Intravascular pumps can provide adequate circulatory support without the need for extensive operatio

While Fontan palliation in the form of the total cavopulmonary connection has improved the management of congenital single ventricle physiology, long-term outcomes for patients with this disease are suboptimal due to the lack of two functional ventri

Piezohydraulic pumps are high power density motors, which can be theoretically miniaturized with minimal loss in power output. The feasibility of using piezohydraulic pumps in pulsatile pediatric ventricular assist devices is presented in this study.
