RESUMO

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 ±â€Š6.88 mm. The reference vessel diameter was 2.32 ±â€Š0.44 mm and the percentage diameter stenosis was 67 ±â€Š12. Procedural success was obtained in all patients. After a median of 6.6 ±â€Š2.5 months, late lumen loss was 0.09 ±â€Š0.34 mm and the percentage diameter stenosis was 31 ±â€Š18. 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.

RESUMO

AIMS: Drug-coated balloons (DCBs) are a recognized alternative to stents for the treatment of in-stent restenosis (ISR), and there is some initial clinical evidence about their efficacy for the treatment of small coronary vessels. Newer-generation DCBs were developed to overcome the reduced deliverability of the previous generation, also warranting a more effective drug delivery to vessel wall. However, the vast majority of new-generation DCBs still lack of reliability due to paucity of clinical data. METHODS: Between 2012 and 2015, all patients treated with Elutax SV DCB (Aachen Resonance, Germany) at nine Italian centers were enrolled in this retrospective registry. Primary outcome was the occurrence of target-lesion revascularization (TLR) at the longest available follow-up. Secondary endpoints were procedural success and occurrence of device-oriented adverse cardiovascular events including cardiac death, target-vessel myocardial infarction, stroke, and TLR. A minimum 6-month clinical follow-up was required. RESULTS: We enrolled 544 consecutive patients treated at 583 sites. Fifty-three per cent of the patients had ISR, and the rest native vessel coronary artery disease. Procedural success occurred in 97.5%. At the longest available clinical follow-up (average 13.3 ±â€Š7.4 months), 5.9% of the patients suffered a TLR and 7.1% a device-oriented adverse cardiovascular event. We did not register cases of target-vessel abrupt occlusion. At multivariate analysis, severe calcification at the lesion site was the first determinant for the occurrence of TLR. CONCLUSION: This registry on the performance of a new-generation DCB shows an adequate profile of safety and efficacy at mid-term clinical follow-up.

RESUMO

OBJECTIVES: With this prospective study we aim at investigating the long-term outcome of a consecutive cohort of patients successfully treated with bioresorbable scaffold (BVS) implantation. BACKGROUND: It is not clearly understood if there is a relation between the technique of BVS implantation and the outcome. METHODS: Between December 2012 and December 2014, all consecutive patients treated with BVS were included in this registry and received an angiographic follow-up. After a run-in phase, all BVS were implanted using a specific technique consisting of aggressive predilation, correct scaffold sizing, visually determined, and high-pressure post-dilation with a noncompliance balloon. Primary endpoint was late lumen loss (LLL) at 1-year angiographic follow-up and ischemia-driven target-lesion revascularization (ID-TLR) at 2-year clinical follow-up. Secondary endpoints were the occurrence of binary restenosis, major adverse cardiac events (MACE), and every single component of MACE (cardiac death, myocardial infarction, TLR) at 2 years. RESULTS: A total of 144 lesions in 122 patients treated consecutively with BVS, were enrolled. Diabetics were 29.5% and acute coronary syndrome at presentation occurred in 29.5% of patients. At the angiographic follow-up LLL was 0.38 ± 0.9. At 2-year clinical follow-up, ID-TLR occurred in eight patients (5.6%). We observed two cases of scaffold thrombosis (1.38%, one early and one very late). At multivariate statistical analysis, STEMI presentation remained a significant predictor for TLR. CONCLUSIONS: In a complex, all-comers real world population, BVS implantation with a specific, and standardized technique showed to be feasible, with acceptable mid-term angiographic and long-term clinical outcome.
