Introduction Myocardial bridging (MB) is a common and usually benign inborn coronary abnormality that may lead to anginal symptoms, acute syndrome, arrhythmias, rarely sudden cardiac death. MB are most commonly localized in the middle segment of left anterior descending artery (LAD). The treatment LAD-MB still challenging. Our objective was assess short- long-term results surgical procedures patients with who had chest pain refractory medical therapy. Methods Between March 2005 January 2020, 26 (19 males 7 females; mean 55.8 ± 12.4 years) underwent surgery. All located mid-segment LAD length 4.2 1.7 cm. Coronary angiography before surgery demonstrated systolic compression more than or equal 70% all patients. Results Twenty-five myotomy one patient bypass grafting (CABG). survived recovered uneventfully. Neither hospital late death nor major complications occurred. Follow-up time 3–173 months (mean 55.7 months). computed tomography scan performed 16 restoration blood flow myocardial perfusion without significant residual artery. were symptom-free currently NYHA Class I. Conclusion symptomatic medication should actively undergo intervention such as CABG eliminate clinical symptoms achieve satisfactory by follow-up findings. Myotomy preferred procedure because its safety results.
