Transluminal balloon dilatation for discrete subaortic stenosis in adults and children: early and intermediate results.
Seven patients (four adults, three children) with discrete subaortic membranous stenosis underwent balloon dilatation using a single or double balloon technique with reduction in systolic gradient across the membrane from 100.42 +/- 19.23 to 29.14 +/- 12.54 mmHg (P less than 0.001). Echocardiography demonstrated thin membranes in all the patients and postprocedure torn fragments could be visualized.  The excellent hemodynamic benefits are sustained during 4-24 months follow-up.  The results indicate that transluminal balloon dilatation can be a safe and effective treatment for thin subaortic membrane.
