“…152,153 There have been a few successful cases of balloon dilation of discrete membranous subaortic stenosis, but long-term efficacy remains unknown, and this condition continues to be designated Class II. Fibromuscular or tunnellike subaortic stenosis and supravalvular aortic stenoses are not amenable to balloon dilation, and these indications remain Class III.…”

“…Patients having any type of fibromuscular component, including those patients with a thin membrane but a fibromuscular base in the outflow tract, were excluded. These forms of the disease, which are almost always collar type, have shown poor results 3,8 and were not attempted for catheter intervention. We also excluded patients with any degree of aortic valve gradient and those with a thin membrane on the outflow tract that becomes markedly reduced in systole, contributing in some way to the stenosis.…”

“…Since its first description in 1985, 1,2 several studies have confirmed that persistent pressure relief is achieved after balloon dilation. [3][4][5][6][7][8][9][10][11][12][13] This treatment has not been widely used, and the experience with percutaneous treatment is very different from surgery. However, the mean gradient reduction in 11 series including 170 patients was 70%.…”

“…However, the mean gradient reduction in 11 series including 170 patients was 70%. [3][4][5][6][7][8][9][10][11][12][13] Selection of patients is an important issue, and only patients with a thin membrane without any fibromuscular component should be attempted. In our series, there was a wide age range; children, adolescents, and adults were included.…”

“…Since 1985, 1,2 several studies have confirmed that persistent pressure relief is achieved after balloon dilation. [3][4][5][6][7][8][9][10][11][12][13] Tearing of the membrane by the balloon provided a mean gradient reduction of 70% in 11 series of patients without resultant aortic or mitral valve dysfunction. However, given the progressive nature of the disease, the long-term efficacy of this treatment remains unknown.…”

Long-Term Outcome of Patients With Isolated Thin Discrete Subaortic Stenosis Treated by Balloon Dilation

Background-Transluminal balloon tearing of the membrane in a thin discrete subaortic stenosis is an alternative to membrane surgical resection. However, the long-term outcome of patients with isolated thin discrete subaortic stenosis treated by transluminal balloon tearing remains unknown. Methods and Results-This 25-year study describes findings from 76 patients with isolated thin discrete subaortic stenosis who underwent percutaneous transluminal balloon tearing of the membrane and were followed up for a mean period of 16Ϯ6 years. The age at presentation had a wide range (2-67 years). The mean age at treatment was 19Ϯ16 years. Immediately after treatment, the subvalvular gradient decreased from 70Ϯ27 to 18Ϯ12 mm Hg (PϽ0.001). No significant postprocedural aortic regurgitation was observed. After a mean follow-up time of 16Ϯ6 years, 11 patients (15%) developed restenosis, 3 patients (4%) progressed to muscular obstructive disease, and 1 patient (1.3%) developed a new distant obstructive membrane. Twelve patients (16%) were redilated at a mean of 5Ϯ3 years after their first treatment, and 4 patients (5%) underwent surgery at a mean of 3Ϯ2 years after their first treatment. Fifty-eight patients (77%) remained alive and free of redilation or surgery at follow-up. Larger annulus diameter and thinner membranes were independent factors associated with better long-term results. Conclusions-Most patients (77%) with isolated thin discrete subaortic stenosis treated with transluminal balloon tearing of the membrane had sustained relief at subsequent follow-ups without restenosis, the need for surgery, progression to muscular obstructive disease, or an increase in the degree of aortic regurgitation.
