Williams-Beuren Syndrome (WS) is a genetic syndrome seen in childhood, characterised by intellectual disabilities, outgoing personalities, elfin-like faces and cardiovascular complications. We report the story of a girl with WS who underwent complex cardiac surgery requiring extracorporeal membrane oxygenation (ECMO), to raise awareness of the perioperative challenges with WS.

At 2 years old, a cardiac murmur was incidentally discovered. Further investigations revealed WS with cardiac manifestations including peripheral pulmonary artery stenosis (PPAS) and supravalvular aortic stenosis (SVAS). Isolated SVAS repair was feasible, however the severity of pulmonary artery hypoplasia deemed her inoperable. Her care was redirected to palliation. 18 months later, she remained in good clinical condition which prompted the multidisciplinary team (MDT) to change their decision and proceed with complex SVAS repair surgery (Brom technique) at the age of 5. Postoperatively, 3 failed attempts to wean from cardiopulmonary bypass preceded veno-arterial ECMO, which lasted 7 days. She stayed in intensive care for 17 days, and in hospital for 28 days. Frequent MDT decision making was crucial during her complex care. The patient is currently 15 years old, in good clinical condition, albeit exercise restrictions.

WS patients have a known increased risk of perioperative sudden cardiac death and increasing use of paediatric ECMO, hence great attention and thorough preparation is required. Clear perioperative care guidelines for WS are essential to secure good outcomes in this patient population. This case demonstrated that MDT involvement and regular communication with the patient were key to deliver the appropriate care throughout her life.
