@entity4618 is the most common pediatric @entity4617 . @entity299 ( @entity299 ) have a natural history of spontaneous regression and are closely associated with @entity2916 ( @entity2916 ). We aimed to evaluate the clinical presentation and outcome of @entity299 and their association with @entity2916 . @entity1 with @entity299 diagnosed in last six years were retrospectively analyzed. A total of 25 @entity5 were identified in seven @entity1 by echocardiography. Three @entity1 were diagnosed prenatally by fetal echocardiography, three @entity1 in the neonatal period and one @entity1 in early infancy. The median followup period was two years (range: 5 months-6 years). Five @entity1 (71%) had @entity5 . Three @entity1 had @entity943 and two @entity1 required surgery. Only 36% (9/25) of the @entity5 regressed. @entity2916 was diagnosed in four @entity1 during the follow-up. @entity299 may have different presentations and clinical course. Surgery is only necessary when hemodynamically significant obstruction is present. As @entity299 are associated with long-term development of @entity2916 and other diagnostic features are not yet typically apparent in the prenatal and neonatal periods, careful evaluation and follow-up are essential to exclude @entity2916 .
