Background: In this study, we report our short- and mid-term surgical results in patients with discrete subaortic stenosis.

Methods: A total of 72 patients (43 males, 29 females; mean age 4.6±4.5 years; range, 6 months to 11 years) who were surgically treated for discrete subaortic stenosis in our clinic between September 2000 and January 2012 were retrospectively analyzed. Limited myectomy in addition to the transaortic excision of the stenotic structure was performed in all patients. Left ventricular outflow tract gradient and aortic valve regurgitation were evaluated by echocardiography following the procedure.

Results: The mean follow-up was 4.9±2.7 (range, 1 to 10) years. No mortality occurred during the early and late postoperative period. Heart block which necessitated the placement of a permanent pacemaker developed in one pediatric patient. The mean preoperative left ventricle systolic gradient which was measured as 48.4±13.7 mmHg (range, 32 to 70 mmHg), diminished to 8.6±5.6 mmHg (range, 4 to 15 mmHg) in the postoperative period. Reoperation was necessary due to recurrent stenosis in two patients (2.7%) during follow-up.

Conclusion: Our study results show that limited myectomy in addition to membranectomy results in good mid-term results without increasing morbidity and mortality.
