Surgically treated XXXX : over 50 years of follow-up.

BACKGROUND: Surgical correction was the treatment of choice for @entity849 until three decades ago, when balloon valvuloplasty was implemented. The natural history of surgically relieved @entity849 has been considered benign but is actually unknown, as is the need for re-intervention. The objective of this study was to investigate the morbidity and mortality of @entity1 with surgically treated @entity849 operated at Aarhus University Hospital between 1957 and 2000. RESULTS: The total study population included 80 @entity1 . In-hospital mortality was 2/80 (2.5%), and an additional four @entity1 died after hospital discharge; therefore, the long-term mortality was 5%. The maximum follow-up period was 57 years, with a median of 33 years. In all, 16 @entity1 (20%) required at least one re-intervention. Pulmonary valve replacement due to @entity338 was the most common re-intervention (67%). Freedom from re-intervention decreased >20 years after the initial repair. In addition, 45% of @entity1 had moderate/severe @entity338 , 38% had some degree of @entity1001 , and 40% had some degree of @entity997 , which did not require re-intervention at the present stage. CONCLUSION: Surgical relief for @entity849 is efficient in relieving outflow obstruction; however, this efficiency is achieved at the cost of @entity338 , leading to @entity1001 and @entity997 . When required, pulmonary valve replacement is performed most frequently >20 years after the initial surgery. Lifelong follow-up of @entity1 treated surgically for @entity849 is emphasised in this group of @entity1 , who might otherwise consider themselves cured.
