As for secondary endpoints, LVOTG decreased from 68.75 ± 24.92 mmHg to 45.70 ± 26.55 mmHg (<i>p</i> = 0.0003), and the maximum interventricular septum thickness at end-diastole decreased from 19.77 ± 5.38 mm to 18.25 ± 5.41 mm (<i>p</i> = 0.0104). The average distance covered in the six-minute walk test increased from 180.00 ± 76.44 m to 317.50 ± 98.38 m (<i>p</i> &lt; 0.0001). Complete relief from chest pain symptoms was observed in 12 patients (60%, <i>p</i> &lt; 0.001), and 19 patients (95%) showed at least a one-class improvement in the New York Heart Association functional class (<i>p</i> &lt; 0.0001).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>This study is the first to incorporate AI guidance into PESA, demonstrating that this approach offers favorable safety and efficacy in the treatment of drug-resistant HOCM.
