ABSTRACT=Objectives The aim of this all-comers registry study was to investigate the technical success, clinical efficacy and safety of a drug-coated balloon (DCB) with paclitaxel combined with citrate ester excipient (CEE) in percutaneous coronary intervention (PCI) of de novo coronary lesions in an all-comers population. 

Methods A total of 338 consecutive PCIs using the DCB (CEE)-only approach comprising 406 de novo lesions were included in the study. Technical success was determined by the successful delivery of the device and no need for bailout-stenting.  

Results The mean follow-up time was 25±12 months. The mean age of patients was 71±11 years and 48% had an acute coronary syndrome. 55% of the patients at risk factor bleeding. The delivery of DCB was successful in 98% of cases. The overall technical success rate was 83%. Bailout stenting was used in 9% of lesions. Rotational atherectomy was used in 11% of cases before the DCB-only approach. The mean diameter of the DCBs used was 2.7±0.5 mm and 38% of DCBs were large (≥3.0mm). The 12-month MACE rates were 5.4±1.7% and 18.3±3.1% in stable CAD and in ACS, respectively. The respective TLR rates were 3.0±1.3% and 8.5±2.3%. Unacceptable acute recoil (>30%) was found in 74% cases that needed repeat revascularization.  No acute vessel closures occurred after DCB treatment. 

Conclusions The DCB-only strategy using paclitaxel-coated (CEE) device was technically feasible, safe and effective in an all-comers population. Acute recoil was found as a significant cause of restenosis after DCB-only strategy.
