摘要：
Background Percutaneous transluminal septal myocardial ablation (PTSMA) is an effective means for symptomatic patients with hypertrophic cardiomyopathy (HCM). We present a rare case in which myocardial bridge (MB) was exacerbated in a patient with HCM treated with PTSMA. Case summary Here, we present a case of HCM with palpitations and exertional dyspnoea for 2 years. There was no obvious epicardial coronary artery compression before PTSMA. Typical angina occurred 2 months after PTSMA. Coronary angiography showed no obvious stenosis of the coronary arteries, but an exacerbated MB in the middle part of the left anterior descending artery. Discussion This patient with HCM presented with typical angina, which might be caused by the rare exacerbation of the MB after PTSMA. Thus, patients with MB should carefully choose PTSMA. Future research is needed for HCM patients complicated with MB treated with PTSMA.
