Background: Percutaneous transluminal coronary angioplasty, while an effective intervention, can frequently lead to acute occlusion with severe consequences. Although clinical trials have demonstrated the efficacy of drug-coated balloons (DCB) in treating acute coronary artery occlusion and in preventing restenosis, there has been limited exploration on the use of DCB in treating de novo lesions in large vessels. Currently, DCB are only recommended for patients with small vessel lesions and in-stent restenosis lesions, those at high risk of bleeding, and other special groups of patients.
Case summary: This report presents a case of successful drug-coated balloon treatment of de novo lesions in large coronary vessels. Postoperatively, the patient demonstrated favorable recovery, with subsequent examination results revealing no significant differences from the previous examination.
Conclusion: The successful treatment of the patient in our case highlights the potential of DCB in the treatment of de novo lesions in large coronary vessels.
