Long-term results of aortic valvuloplasty for XXXX associated with @entity1757 .

@entity1 @entity177 @entity337 @entity1757
Long-term results in 64 @entity1 who underwent aortic valvuloplasty for @entity337 associated with @entity1757 are presented. The average age of the @entity1 was 10.2 years and the average cardiothoracic ratio was 0.57 at the time of operation. The average degree of @entity337 , as classified by Sellers, was 2.7. The type of @entity1757 was subpulmonic in 31 @entity1 , perimembranous in 20, and was a total conal defect in five @entity1 . Valvuloplasty was performed at one end of an aortic cusp in 23 @entity1 , at two ends in 33, at three ends in six, and at four ends in two @entity1 . There was one operative death (1.6%). The follow-up period was 447.7 @entity1 -years, and there were no late deaths. The actuarial survival rate was 98.3% at 5, 10, and 15 years. Postoperative cardiac catheterization was performed in 40 @entity1 . @entity177 was defined as the presence of a cardiothoracic ratio greater than 0.6, a loud regurgitant murmur (Levine grade 3/6 or greater), moderate or severe @entity337 (Sellers grade 3 or 4), or the necessity of reoperation. There were 17 @entity1 whose valvuloplasty failed. The freedom from valvuloplasty failure was 74.2% at 5 and 10 years and 55.3% at 15 years. Eight @entity1 underwent reoperation because of residual @entity337 , and all survived. The freedom from reoperation was 90.1% at 5 years, 80.5% at 10 years, and 63.7% at 15 years. Multiple regression analysis revealed that older age, a greater cardiothoracic ratio, perimembranous @entity1757 , and multiple valvuloplasties were significant contributing factors for residual regurgitation after aortic valvuloplasty.
