Pulmonary artery pulsatility index (PAPi) is a haemodynamic parameter that is derived from right atrial and pulmonary artery pulse pressures. A number of reports have described the prognostic value of PAPi in patients with advanced heart failure and cardiogenic shock.

We obtained PAPi besides common haemodynamic parameters in right heart catheterization before LVAD implantation.

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!!

After understanding the patient’s LVAD parameters, we can now recommend small boluses of intravenous fluids to reverse overdiuresis and return the LVAD parameters back to baseline. The LVAD recipients exhibited a significantly attenuated pulsatility index (PI) compared to controls prior to treatment (LVAD: 2±1; Controls: 15±2 AU, p<0.05), however, during the treatment PI was no longer different (LVAD: 37±10; Controls: 36±4 AU). A CF-LVAD consists of the inflow cannula that sits in the left ventricular (LV) cavity, the pump impeller that rotates at a constant pre-set speed, and the outflow graft that continuously delivers blood into the aorta, augmenting the circulation throughout the entire cardiac cycle with low to no arterial pulsatility. Pulsatility Index (PI): 1 – 10; How often does life threatening VAD malfunction occur?

PI is the magnitude of this flow pulse . The pulsatility index (PI) will normally decrease as pump speed is increased low power with low pulsatility index and steady pump speed. causes: inflow/ outflow obstruction, LV failure, dysrhythmia, hypertension; low power with normal or high pulsatility index.

Jan 2, 2020 Pulmonary Artery Pulsatility Index. Pulmonary Artery Pulsatility Index (PAPi) is a recently described hemodynamic index, which has been used to

Acutely, a larger flow into the cerebral circulation will result in increased resistance and possibly higher pressure. A low pulsatility has been advocated to be associated with increased rates of aortic insufficiency and bleeding; 5 HVAD and Heartmate 3 (HM-3) provide the possibility of estimate pulsatility and pulsatility index respectively and have incorporated features favouring pulsatility and aortic valve opening (Lavare cycle for HVAD and artificial pulse for HM-3), but, even if the rate of The pulmonary artery pulsatility index (PAPi) is a reliable marker of RV dysfunction in the setting of myocardial ischemia and RV failure post LVAD. However, its use in patients with pulmonary hypertension has not been properly evaluated. We aim to assess the use of PAPi in the evaluation of patients with PAH. Cardioversion/defibrillation can be performed on an LVAD patient TYPES OF CONTINUOUS FLOW LEFT VENTRICULAR ASSIST DEVICES HeartMate II™ Axial Flow Pump Speed: 8000-10000 rpms Flow: 4 – 6 Ipm Power: 4 – 6 watts Pulsatility Index: 4 – 7 MAP: 70 – 90 mm Hg Warfarin/Aspirin Pair of Batteries = 10 – 12 hours Emergency Battery in Controller However, AVO frequency was independent of opening area and systolic duration, which both decreased with increasing LVAD support. Furthermore, aortic pulsatility index quadrupled in the aortic root and doubled in the distal aorta during PLSA conditions, providing evidence that AVO and blood mixing are enabled by PLSA control at the appropriate utility of the PA pulsatility index (PAPi) as a measure of RV failure in the setting of acute MI.32 The PAPi is the ratio of PA pulse pressure divided by RA pressure.

Pulsatility Index (PI) 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

Setting.

Mechanical circulatory support using left ventricular assist devices (LVADs) is an established treatment option for patients with advanced heart failure resulting in improved mortality and quality of life compared to standard medical therapy. 1 Despite the evolution of technology, 10%–40% of patients develop severe right ventricular failure (RVF) after LVAD implantation. 2–4 The large (12) The resistive index (RI) and pulsatility index (PI) have been used in the evaluation of ovarian masses because of the expected low impedance and high diastolic blood flow seen in blood vessels supplying the malignant tumor. Imaging of ovarian cancer Pulsatility index (PI) – represents the balance of native ventricular function and unloading by the continuous flow VAD. An increase could suggest recovery of ventricular function whereas a decrease represents hypovolemia, worsening ventricular function, or increased pump speed causing more ventricular unloading and less pulsatility LVAD is working.
