Aortic Regurgitation in Patients with Left Ventricular Assist Device: A Contemporary Review

Aortic regurgitation (AR) developing under continuous flow-left ventricular assist devices (CF-LVAD) affects 25-30% of patients within the first year of implantation and is being increasingly recognized as a cause of recurrence of symptomatic heart failure (HF). The underlying mechanisms are likely multifactorial, including changes in the leaflets of the aortic valve (AV), altered root biomechanics and excessive left ventricular (LV) unloading, together promoting cusps remodeling and commissural fusion.
