WebJan 20, 2024 · Pulmonary venous hypertension secondary to high left-sided filling pressures is not a contraindication to VAD implantation, and actually, VAD therapy will likely improve the pulmonary artery pressures by decreasing pulmonary venous pressures. WebAs patients with LVADs have minimal (if any) left ventricular pulsatility, non-invasive blood pressure recordings as well as pulse-oximeter readings are unreliable. 19 A bedside measurement, called a “return to flow” is one way of assessing mean arterial pressure in patients with LVADs.
