Patients with primary mediana 010 or 001 left main bifurcation lesions were treated with drug ball coated balloon from November 2018 to November 2020 in four hospitals in Huaihai area. The clinical characteristics, pathological changes, operation process and perioperative drug treatment data were collected. Clinical follow-up included hospitalization, postoperative telephone or outpatient follow-up. Objective to compare the safety and efficacy of drug-eluting balloon and drug-eluting stent implantation alone in the treatment of primary mediana 010 or 001 left main bifurcation lesions.', 'detailedDescription': 'At present, the primary left main trunk end bifurcation lesions with mediana classification of 010 or 001 are mainly treated by crossing stent technique or direct precise positioning stent technology. Because of the difficulty of precise stent placement, the displacement of cristae across stent implantation is easy to affect the distal vessels of the side branch or main branch, and the long-term clinical efficacy is not good, so the standardized interventional therapy is still controversial. Recently, a registered study published by regatelli et al. Showed that spanning stent technology seems to be superior to precise positioning stent technology, but the major adverse cardiac event rate in clinical follow-up is high.\n\nDrug coated balloon (DCB) as a new interventional therapy in recent years, has been gradually used in the treatment of primary coronary artery disease in situ. The latest international consensus on the treatment of coronary heart disease with DCB indicates that more and more clinical studies have shown the safety and effectiveness of DCB in the treatment of coronary artery disease (≥ 3.0 mm). However, there are few studies on the interventional therapy of DCB in the primary mediana type 010 or 001 left trunk end bifurcation lesions, especially the combination of "1-2mm" drug-eluting stent (DES) implantation when necessary.\n\nThe purpose of this study was to investigate the feasibility and short-term clinical efficacy of DCB combined with DES implantation in the treatment of primary mediana 010 or 001 left main bifurcation lesions, and to explore a new treatment for such lesions.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
