Vitanova K, et al. - Researchers reviewed shunt failure and shunt-related mortality by analysing data of all patients with biventricular circulation who underwent systemic-to-pulmonary artery shunt implantation between 2000 and 2016. They defined shunt-related mortality as death due to shunt dysfunction. They reported that perioperative platelet transfusion and shunt size of 3 mm were identified as risk factors for shunt failure. In addition, shunt size of 3 mm was identified as a risk factor for shunt-related mortality. They suggested that platelet transfusion raises the risk of shunt failure and should be avoided, however, type of shunt and diagnosis had no impact on morbidity or mortality after shunt placement.
