Seven patients, mean age 8 +/- 3.6 years, with clinical and hemodynamic diagnoses of discrete subaortic stenosis were treated by percutaneous transluminal balloon dilatation (PTBD) of the membrane during cardiac catheterization with results consistent with hemodynamic findings.Abstract:
Seven patients, mean age 8 +/- 3.6 years, with clinical and hemodynamic diagnoses of discrete subaortic stenosis were treated by percutaneous transluminal balloon dilatation (PTBD) of the membrane during cardiac catheterization. One patient had an associated aortic coarctation that was first dilated. After PTBD left ventricular (LV) systolic pressure decreased significantly, from 181 +/- 25 to 139 +/- 11 mm Hg (p less than 0.005); peak gradient diminished from 65 +/- 18 to 12 +/- 9 mm Hg (p less than 0.001). Mild aortic regurgitation was present in 6 patients during basal conditions. After PTBD, the same degree of regurgitation was observed in all but 1 patient, in whom it disappeared. There were no major complications. Clinical observations after PTBD were consistent with hemodynamic findings. Precordial thrill always disappeared and the peak murmur became earlier in systole. In 2 patients the discrete subaortic stenosis was clearly visualized at 2-dimensional echocardiography as a fixed subvalvular structure throughout the cardiac cycle. After dilatation this was only identifiable at its implantation base; during contraction there was no fixed structure at the LV outflow tract. Four patients were hemodynamically reevaluated 6.7 +/- 1.7 months later and were found to have LV pressure relief and a degree of aortic regurgitation similar to those observed immediately after PTBD.read more

TL;DR: Because there was a very heterogenous group of lesions both in types of lesions and techniques of dilation, only minimal data can be offered concerning the efficacy of the dilation of any or all of these lesions.

TL;DR: In this review, current state-of-the-art for each broad area of therapeutic catheterization is presented and a large variety of lesions could be opened-up or closed, as the case may be and the results were either similar to or better than those reported for the alternative surgical therapy.

Interventional catheterization in pediatric congenital and acquired heart disease.
TL;DR: The present status of catheter-directed therapy in pediatric congenital and acquired heart disease is reviewed and balloon pulmonary valvotomy, established as the procedure of choice for children and adults with isolated pulmonary stenosis, has now been extended to neonates with critical pulmonary stenotic.

TL;DR: It is indicated that balloon pulmonary valvotomy can be safely performed and is effective palliation in selected patients with cyanotic heart disease that is not suitable for primary repair and may improve oxygenation and growth of the pulmonary arteries without the need of a systemic to pulmonary artery shunt.

TL;DR: In none was there a significant change in peak systolic aortic valve pressure gradient or cardiac output compared with the study immediately after valvuloplasty, but all patients had a lessened gradient.

TL;DR: The criteria for operability of discrete subaortic stenosis should be the angiographic demonstration of a discrete subvalvular diaphragm and the presence of a resting left ventricular to aortic systolic pressure gradient of 40 mm Hg or more.

TL;DR: It is reasonable to resect discrete SAS in children less than 10 to 12 years old with LV outflow gradients greater than or equal to 30 mm Hg, and in patients with tunnel SAS the reduction was less satisfactory.

TL;DR: Even after resection, patients with discrete membranous subaortic stenosis require continued re-evaluation for residual or new LV obstruction, and possible explanations are discussed.

TL;DR: Early evaluation indicates that percutaneous balloon valvuloplasty may be useful in the definitive treatment of isolated pulmonary valve stenosis in some patients and of palliative value in others.
