About

This study evaluates the Efficacy and Safety of Paclitaxel-Coated Balloon Catheter in Patients With Diffuse Long De Novo Lesions of Main Coronary Arteries.

Full description

Paclitaxel-Coated Balloon Catheter is a new device in coronary disease, it can inhibit the proliferation of smooth muscle of coronary vessels by transitory contaction, without residual implantation.

More and more evidences have shown its efficacy and safety in diffuse small coronary disease, bifurcation disease and in-stent restenosis. But there are still seldom evidences in De Novo Lesions of Main Coronary Arteries.

PCB has used in some subgroup of many study but confused with in-stent renstenosis or small coronary disease. The investigators designed this study to evaluate the Efficacy and Safety of Paclitaxel-Coated Balloon Catheter in Patients With Diffuse Long De Novo Lesions of Main Coronary Arteries.
