Overview
This registry aimed to investigate drug-coated balloon procedural factors (particularly delivery time and inflation duration) to evaluate the impact on angiographic and clinical outcomes in patients undergoing percutaneous coronary intervention for de novo coronary lesions.
Description
This study aimed to systematically investigate drug-coated balloon procedural factors including Y-to-B delivery time, inflation duration among patients with de novo coronary lesions undergoing PCI.The impact of these procedural factors on angiographic and clinical outcomes will be analyzed.Based on these findings, novel techniques and pretreatment strategies may be proposed to optimize the DCB treatment process
