Aims To evaluate the angiographic performance of a novel sirolimus-coated balloon (SCB) in de novo coronary lesions.

Methods Out of an all-comer prospective registry of patients treated with the SCB at our center from April 2016 to September 2017, we selected those treated for a de novo stenosis on a native vessel, with a scheduled angiographic control at at least 4 months after the index procedure. We performed a centralized, blinded core-lab adjudicated quantitative coronary angiography analysis. Primary endpoint was late lumen loss. Secondary endpoints were binary restenosis and target-lesion revascularization.

Results A total of 27 patients with native coronary arteries treated with SCB and with angiographic follow-up entered the study; seven patients were excluded because a stent was implanted at the lesion site during the index procedure. The degree of calcification (assessed with coronary angiography) was high in six patients (30%) and the average lesion length was 20.52 ± 6.88 mm. The reference vessel diameter was 2.32 ± 0.44 mm and the percentage diameter stenosis was 67 ± 12. Procedural success was obtained in all patients. After a median of 6.6 ± 2.5 months, late lumen loss was 0.09 ± 0.34 mm and the percentage diameter stenosis was 31 ± 18. We observed two cases (10%) of binary restenosis which underwent subsequent target-lesion revascularization: in one a drug-eluting stent was implanted, whereas the other patient was treated with paclitaxel-coated balloon. No myocardial infarction or death was observed during follow-up.

Conclusion The use of a novel SCB in native coronary arteries was associated with good angiographic outcome at 6-month follow-up.
