Most patients of 52 patients in center 1 were male (34\/52 [65.3%]).and the mean age was of 36.7\u2009\u2009\u00b1\u2009\u200919 years. Syncope before admission was reported in 5.7%, the mean left ventricular ejection fraction on admission was 53\u2009\u2009\u00b1\u2009\u20098%, the mean left ventricular outflow tract gradient was 66.3\u2009\u2009\u00b1\u2009\u200920.4 mm Hg, and the mean preoperativeseptal thickness was 25.4\u2009\u2009\u00b1\u2009\u20096.7 mm. A redo SM was performed in 3 patients (5.8%), mitral valve repair in 5 patients (9.6%), and atrioventricular repair in 5 patients (9.6%). A residual systolic anterior motion was detected in 4 patients (7.7%), the mean postoperative septal thickness was 19\u2009\u2009\u00b1\u2009\u20096 mm (25.1% septal thickness reduction), and in-hospital mortality was 5.8% (n\u2009\u2009=\u2009\u20093). A longer-term follow-up showed death in 3 patients (5.8%) and late recurrent left ventricular outflow tract obstruction in 1 patient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Transaortic myectomy is an effective surgery with acceptable early and late mortality rates.
