The pulmonary artery pulsatility index (PAPi), defined as the ratio of pulmonary artery pulse pressure to right atrial pressure (RAP), predicts RVF after acute inferior myocardial infarction and 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). 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). 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).

A suction event is a common LVAD complication and is associated with low flow events, including dysrhythmia, hemorrhage, and other hypovolemic states such as diarrhea or vomiting. 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 We explored the association of preimplantation Pulmonary Artery Pulsatility index (PAPi) and other hemodynamic parameters as predictors of prolonged postoperative inotropes/pulmonary vasodilator use after CF‐LVAD implantation.
