Rotational ablation is receiving increasing attention as a new therapeutic intervention for coronary artery disease. In a nonrandomized study, we compared echocardiographic regional wall-motion scores of patients treated with rotational ablation with those of patients treated with percutaneous transluminal coronary angioplasty. We found that rotational ablation achieved angiographic results comparable to those of percutaneous transluminal coronary angioplasty, and was in fact associated with less myocardial ischemia. The reduction in ischemia observed in the ablation group might arise from shorter treatment times in those patients, from the use of nitroglycerin infusion in the ablation group, or from both factors.
旋磨术作为一种治疗冠状动脉疾病的新的治疗手段正受到越来越多的关注。在一项非随机研究中，我们比较了接受旋磨术治疗的患者与接受经皮腔内冠状动脉成形术治疗的患者的超声心动图局部室壁运动评分。我们发现，旋磨术取得的血管造影结果与经皮腔内冠状动脉成形术相当，而且实际上与较少的心肌缺血相关。消融组观察到的缺血减少可能源于这些患者较短的治疗时间、消融组中硝酸甘油输注的使用，或这两个因素。
