Efficacy and safety of the adenosine administration test in the management of Wolff-Parkinson-White pattern in children with delta waves.

Background: The Wolff-Parkinson-White pattern is a delta wave frequently detected in school-based cardiovascular screening programs in Japan. Although most children with Wolff-Parkinson-White pattern are asymptomatic, initial symptoms may include syncope or sudden death, necessitating accurate diagnosis and management. Delta waves can also indicate a fasciculoventricular pathway, which poses no risk and does not require management.

Successful use of long-acting octreotide for protracted gastrointestinal bleeding related to protein-losing enteropathy after the Fontan procedure: a case report.

Gastrointestinal bleeding complicated with protein-losing enteropathy after the Fontan procedure has been often reported in recent years, but there is no established therapy for it.We report the case of an 18-year-old boy who suffered from abdominal pain, melena, and anaemia due to intractable haemorrhagic protein-losing enteropathy after the Fontan procedure. He was successfully treated with octreotide therapy.

Sliding Aortoplasty for Severe Supravalvular Aortic Stenosis After the Lecompte Procedure.

This report describes the case of a 3-year-old boy with supravalvular aortic stenosis after an arterial switch operation in whom the stenosis was successfully repaired using an ascending sliding arch aortoplasty without using a patch. Because patches were avoided, growth of the surgical site is expected. Ascending sliding arch aortoplasty and longitudinal expansion of the pulmonary bifurcation are useful for relieving stenosis and preventing supravalvular aortic stenosis recurrence after an arterial switch operation.
