Clinical and angiographic outcome of a single center, real world population treated with a dedicated technique of implantation for bioresorbable vascular scaffolds. The FAtebenefratelli Bioresorbable Vascular Scaffold (FABS) registry.

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.

Immediate and short-term performance of a novel sirolimus-coated balloon during complex percutaneous coronary interventions. The FAtebenefratelli SIrolimus COated-balloon (FASICO) registry.

BACKGROUND AND PURPOSES: Drug-coated balloons (DCB) currently represent an alternative to drug-eluting stents (DES) for the treatment of in-stent restenosis and they are also variably used for small coronary vessel and bifurcation lesion management. All DCB variably elute paclitaxel as an anti-proliferative drug. The first sirolimus coated balloon (SCB) received the CE mark in 2016, but its clinical performance has not been shown yet. METHODS AND RESULTS: FASICO in an all-comer registry of the first consecutive patients with at least one lesion treated with SCB between March and July 2016 at the first European centre that used this device. All patients were prospectively enrolled in a dedicated database. Primary endpoint was procedural success; co-primary endpoint was the rate of major adverse cardiac events at short-term follow-up. The 32 patients (34 lesions) enrolled had at least 6-month clinical follow up available. Forty-five percent had diabetes and indication to PCI was ISR in 47% of the cases. Lesions were always pre-dilated and device deployment was successful in all the cases. Procedural success was achieved in 100% of patients. We observed 3 cases of TLR at follow-up. CONCLUSIONS: SCB shows high immediate technical performance and adequate short-term efficacy and safety. The ongoing EASTBOURNE registry will shed light on mid-and long-term performance of this device in an adequately powered population.

Comparison of risk of acute kidney injury after primary percutaneous coronary interventions with the transradial approach versus the transfemoral approach (from the PRIPITENA urban registry).

The risk of acute kidney injury (AKI) is a major issue after percutaneous coronary interventions (PCIs), especially in the setting of ST-elevation myocardial infarction. Preliminary data from large retrospective registries seem to show a reduction of AKI when a transradial (TR) approach for PCI is adopted. Little is known about the relation between vascular access and AKI after emergent PCI. We here report the results of the Primary PCI from Tevere to Navigli (PRIPITENA), a retrospective database of primary PCI performed at high-volume centers in the urban areas of Rome and Milan. Primary end point of this study was the occurrence of AKI in the TR and transfemoral (TF) access site groups. Secondary end points were major adverse cardiovascular events, stent thrombosis, and Thrombolysis in Myocardial Infarction major and minor bleedings. The database included 1,330 patients, 836 treated with a TR and 494 with a TF approach. After a propensity-matched analysis performed to exclude possible confounders, we identified 450 matched patients (225 TR and 225 TF). The incidence of AKI in the 2 matched groups was lower in patients treated with TR primary PCI (8.4% vs 16.9%, p = 0.007). Major adverse cardiovascular events and stent thrombosis were not different among study groups, whereas major bleedings were more often seen in the TF group. At multivariate analysis, femoral access was an independent predictor of AKI (odds ratio 1.654, 95% confidence interval 1.084 to 2.524, p = 0.042). In conclusion, in this database of primary PCI, the risk of AKI was lower with a TR approach, and the TF approach was an independent predictor for the occurrence of this complication.
