Myocardial bridging (MB) is a congenital variation in which a coronary artery segment tunnels through the myocardium instead of following its usual epicardial route. Although MB is usually diagnosed incidentally and has a good long-term prognosis, it can lead to complications such as angina, myocardial infarction, arrhythmias, and sudden death. This study aimed to evaluate the outcomes of drug-eluting stent (DES) implantation in patients with MB and medically refractory angina. The study included 12 patients with significant MB who did not respond to maximal medical therapy and underwent DES implantation. The patients were followed up for a mean duration of 33 months. The procedural success rate was 92%, with only 1 patient experiencing acute coronary artery rupture during the procedure. During the follow-up period, none of the patients reported angina symptoms, required additional percutaneous coronary intervention, or developed stent thrombosis. One patient (8.3%) died from a non-cardiac cause. The procedure demonstrates a high procedural success rate and leads to favorable long-term outcomes, including the absence of angina symptoms and the avoidance of stent-related complications. In conclusion, this study suggests that DES implantation can serve as an effective treatment option for selected patients with medically refractory angina and significant MB.
