以色列学者Banai等研究发现,在冠状窦中置入支架造成冠状窦局限性狭窄可治疗慢性顽固性心绞痛。该学者在15例不适合行CABG和PCI、具有可逆性心肌缺血的严重心绞痛患者冠状窦中置入特制的不锈钢支架,造成冠状窦局限性狭窄,冠状窦压力升高。随访6个月结果发现,患者心绞痛症状明显 Israeli scholar Banai and other studies have found that placement of coronary stents in the coronary sinus caused by stenosis can treat chronic refractory angina. The scholar placed a special stainless steel stent in the coronary sinus of 15 patients with severe angina pectoris who were not eligible for CABG and PCI and reversible myocardial ischemia, resulting in stenotic coronary stenosis and elevated coronary sinus pressure. Follow-up of 6 months found that patients with angina symptoms
