Coronary artery treatment with a urea-based paclitaxel-coated balloon: The European wide Falcon all comers DCB Registry (FALCON-Registry)

AIMS: The aim of this study was to investigate the use of a drug-coated balloon (DCB) in daily clinical practice and provide further evidence on the safety and efficacy of paclitaxel-coated balloon treatment using urea as an inert excipient.

METHODS AND RESULTS: Between December 2013 and December 2015, 757 patients treated for coronary lesions with the IN.PACT Falcon balloon were enrolled in this prospective real-world all-comers registry. The primary outcome was the clinically driven target lesion revascularisation (TLR) rate at 12 months. The secondary outcome was major adverse cardiac events (MACE) defined as cardiac death, myocardial infarction, TLR and target vessel revascularisation (TVR). Out of 805 lesions, 43.1% were de novo, and 53.2% drug-eluting stent (DES) or bare metal stent (BMS) in-stent restenosis (ISR). TLR at 12 months was 6.2% and TVR 8.3%. MACE occurred in 9.7% of patients with a composite of cardiac death in 0.8% and myocardial infarction in 2.7% plus TLR/TVR. Subgroup analysis confirmed a TLR rate of 7.5% for ISR (2.1% BMS and 9.5% DES) and 4.9% for de novo lesions.

CONCLUSIONS: The IN.PACT Falcon urea-based paclitaxel-coated balloon is safe and efficient in de novo and ISR lesions with low rates of TLR/TVR. The high proportion of treatment of de novo lesions indicates that a DCB-only strategy is nowadays common.
