Objective: Predictors of right ventricle (RV) dysfunction after continuous‐flow left ventricular assist device (CF‐LVAD) implantation in children are not well
Pulsatility may result from blood ejected through the aortic valve or transmission of the systolic pressure wave through the LVAD (in cases of a closed aortic valve). The HeartMate II and HVAD both identify changes in power (and corresponding flow) during systole and diastole using either a pulsatility index or a flow waveform.
At this point in the procedure, the endoscopist notes she is unable to localize the bleeding source, and will have to perform a double balloon enteroscopy. LVAD will lose power and stop working. It is critical to patient health that the LVAD be powered at all times.3,5,7,8 Pulsatility Index. Changes in a patient’s blood pressure (BP) can affect flow, with higher BP causing a decrease in flow.

Pulmonary Artery Pulsatility Index Pulmonary Artery Pulsatility Index (PAPi) is a recently described hemodynamic index, which has been used to predict right ventricular failure in those with inferior wall infarction and in those who have been implanted with left ventricular assist device (LVAD). As the left ventricle contracts and relaxes, the flow through the pump increases and decreases, adding a degree of pulsatility PI is the magnitude of this flow pulse The pulsatility index (PI) will normally decrease as pump speed is increased First generation LVADs had pulsatile flow Subsequent designs use continuous flow - patient will not have a palpable pulse Patient will be on anticoagulation and antiplatelet therapy secondary to high risk of pump thrombus, CVA, and other thromboembolic events a small tube that carries blood out of the heart into a pump then blood pumped back into the aorta (LVAD) or pulmonary artery (RVAD) can be continuous flow (cf-VAD) rather than pulsatile (generally older models); cf-VADs are smaller, quieter, and durable 2 main types of pumps currently used: 1. centrifugal (~2,500 rpm) Pulsatility Index: Not applicable MAP: 70 – 90 mm Hg Warfarin/Aspirin Pair of Batteries = 8 – 12 hours No Emergency Battery in Controller HeartMate 3™ Speed: 4800-6500 rpms Pulsatility Index: 2 – 6 Pair of Batteries = 15 hours Emergency Battery in Controller UR Medicine Transfer Center: 1-800-499-9298 585-275-4999 • LVAD’s can provide up to 10 L/min of cardiac output • The device estimates cardiac output based on power consumption and speed • HVAD and HM3 use hematocrit to estimate serum viscosity to allow for more accurate flow estimation • ESTIMATE!!
Jan 16, 2015 The parts, placement, and function of an implantable left ventricular assist device (LVAD) are then shown for treatment of severe left-sided heart
Alarms. The controller will alarm if there is low battery, suction events, low flow, high power usage, which can aide in trouble-shooting the LVAD.
Pulsatility Index. The HMII calculates the PI as (maximum power – minimum power)/(average power) averaged over 15 seconds. This value was displayed by the device monitor and was retrieved daily, simultaneous to PP assessment along with the LVAD speed (rpm), flow (L/min), and power (W).

CF-LVAD flow rate was measured with a Transonic ME13PXN flow probe at the outlet of the pump, connected to a Transonic 410 flow meter (Transonic, Ithaca, NY). The pulsatility was quantified using the index of pulsatility (I p) considering the fact that aortic valve remained
Pump Speed How fast the LVAD pump is spinning to circulate blood through your body; it is measured in revolutions per minute (RPM).

The pulsatility index (PI) (also known as the Gosling index) is a calculated flow parameter in ultrasound, derived from the maximum, minimum, and mean Doppler frequency shifts during a defined cardiac cycle. Along with the resistive index (RI), it is typically used to assess the resistance in a pulsatile vascular system. Pulsatility Index (1 – 10). A measure of how much the hearts native contraction contributes to cardiac output. If low, suggest hypovolemia or poor native LV function.
The usual range is 8,600 to 9,800 rpm.

The pulmonary artery pulsatility index (PaPi) is a recently described hemodynamic metric. We evaluated baseline PaPi as a predictor of post-operative right ventricular failure (RVF) following LVAD surgery. Methods: We conducted a retrospective review of 132 consecutive LVAD implantations at our hospital.
The HMII calculates the PI as (maximum power – minimum power)/(average power) averaged over 15 seconds.
