@entity849 development and XXXX in atrioventricular septal defect: a case report.

@entity1 @entity120 @entity1757 @entity1163 @entity3888 @entity849 @entity299 @entity6924 @entity848
A 24-year-old @entity1 was admitted for dyspnoea and @entity1163 . He had a previous history of complete @entity1757 . At the age of 6 months, in 1984, cardiac catheterization revealed a quasi-systemic @entity120 with a bidirectional shunt corresponding to an @entity6924 . Corrective cardiac surgery was not performed at this time because surgical risk was considered too high. Until the age of 20 years old, he showed few symptoms while under medical treatment. But since 2006, his functional status became worse with an increased dyspnoea, @entity1163 , and severe @entity848 . In these conditions, haemodynamic parameters have been re-evaluated in 2006 and 2008.They highlighted a late and progressive development of a valvular and @entity3888 leading to a normalisation of pulmonary arterial pressures. At the age of 24 , the @entity1 underwent corrective cardiac surgery which was successful. Late development of both infundibular and @entity849 have not been described before in non operated congenital @entity1757 , but development of one or the other abnormality would be found in 8% of @entity1 . The physiopathological mechanism of this obstruction is unclear. Nevertheless, in unoperated @entity299 , reversibility of severe @entity120 should be reconsidered and re-assessed during follow up.
