CCAS is a society organized within the Society for Pediatric Anesthesia. The CCAS concept originated with cardiac anesthesia directors and other key leaders at major congenital heart disease programs, who believed there was a need for a new society because of rapid advancement of highly specialized knowledge in the field, and a great increase in the numbers of patients, including adults with congenital heart disease.

Question of the Week
A 3 kg neonate undergoes a Norwood-mBTT shunt procedure for hypoplastic left heart syndrome (HLHS). Following a prolonged cardiopulmonary bypass run, the patient is placed on veno-arterial (VA) ECMO postoperatively. After several days of support, a clamp trial is performed to assess readiness for decannulation. The patient is transitioned to full mechanical ventilation and restarted on inotropic support. The patient immediately demonstrates signs of hemodynamic instability and inadequate gas exchange, and the trial is aborted. Upon reinstitution of VA ECMO with adequate circuit flow, the patient exhibits persistently low saturations. The ECMO circuit appears intact with no signs of clot or flow disturbance. Which of the following is the MOST LIKELY cause of the desaturation?
A. Air entrainment in the arterial cannula
B. Sweep gas flow was not restored
C. Oxygenator membrane failure
