Twenty-four patients underwent SM, and 16 patients underwent PSMA. All patients were symptomatic despite maximal medical treatment and had an LVOT gradient higher than 65 mm Hg. Their echocardiographic data were recorded before and after the procedure and then compared. The patients were followed up postoperatively for a mean of 13 months.</p><p><b>Results:</b> There was no mortality in either group. One year after the procedure, the LVOT gradients for the 2 groups were not statistically different. During the follow-up, moderate MR was found in 4 patients (25%) in the ablation group and in 2 patients (8.3%) in the myectomy group. Exercise capacity and New York Heart Association class improved after PSMA, whereas postoperative MR severity and effort capacity were better in the surgical group.</p><p><b>Conclusion:</b> The 2 approaches yielded similar results with regard to reducing the LVOT gradient. We conclude that SM is preferable to PSMA in cases with MR.</p>}, number={6}, journal={The Heart Surgery Forum}, author={Vural, A.
