(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

Right ventricular failure (RVF) is a major cause of morbidity and mortality after left ventricular assist device (LVAD) implantation. The pulmonary artery pulsatility index (PAPi) is a novel hemodynamic index that predicts RVF in the setting of myocardial infarction, although it has not been shown to predict RVF after LVAD implantation.

Assessment of Doppler Blood Pressure Continuous and pulsatile-speed CF-LVAD assistance provided the same mean arterial pressure and flow rate, while the index of pulsatility increased significantly for both arterial pressure and pump flow rate signals under pulsatile speed pump support. 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. Pulmonary artery pulsatility index predicts right ventricular failure after left ventricular assist device implantation. journal of heart and lung transplantation Kang, G., Ha, R., Banerjee, D. 2016; 35 (1): 67-73 Abstract.

The pulmonary artery pulsatility index (PAPi), defined as [ (systolic pulmonary artery pressure – diastolic pulmonary artery pressure)/CVP], is a hemodynamic index originally used to predict RVF in inferior wall acute myocardial infarctions. Recently, PAPi has also been shown to be an independent predictor of postoperative RVF in continuous-flow

Dec 1, 2020 PDF | An increasing number of end-stage heart failure patients are now implanted with continuous-flow left ventricular assist devices LVAD controller parameters (alarms, rotary speed, power consumption, flow, pulsatility index);; Blood pressures (pulmonary artery pressure, mean arterial Aug 24, 2014 Left ventricular assist devices (LVADs) have gained widespread use as Pulsatility index (PI) is another common definition for quantifying Jan 3, 2014 First what is a left ventricular assist device (LVAD from here on out): And the PI is calculated from flow (max flow- min flow/avg flow over 15 BACKGROUND: Right ventricular failure (RVF) is a major cause of morbidity and mortality after left ventricular assist device (LVAD) implantation. The pulmonary Hypertension. – Effects on pump support. • May decrease forward flow.

The pulsatility index is low because the pump has to work harder to maintain the same cardiac output and flow since the patient’s volume and native heart function are low. 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.

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.
