Management of Patients Treated With Oral Anticoagulant Therapy Undergoing Percutaneous Coronary Intervention With Stent Implantation: The PERSEO Registry.

ABSTRACT: In patients on oral anticoagulant (OAC) therapy undergoing percutaneous coronary intervention (PCI) with stent, international guidelines endorse the use of direct oral anticoagulants (DOAC) rather than vitamin K antagonists (VKA) and dual antithrombotic therapy (DAT) rather than triple antithrombotic therapy (TAT). The aim of this study was to evaluate contemporary real-world data on antithrombotic regimens and outcome in patients on OAC undergoing PCI with stent. Consecutive patients on OAC undergoing PCI were enrolled in the multicenter, prospective, observational PERSEO registry (NCT03392948). Primary end point was net adverse clinical events (NACE) with VKA versus DOAC, whereas a secondary prespecified end point was NACE with DAT versus TAT both at 1-year follow-up. From February 2018 to February 2022; in total, 1234 consecutive patients were included. The main indication for OAC was atrial fibrillation (86%), and the mean CHA 2 DS 2 VASc and HAS-BLED scores were 4 ± 2 and 3.6 ± 1, respectively. Of the 1228 patients discharged alive, 222 (18%) were on VKA and 1006 (82%) on DOAC ( P < 0.01). DAT was employed in 197 patients whereas TAT in 1028. At follow-up, NACE rate was significantly higher than VKA compared with DOAC (23% vs. 16%, P = 0.013) and confirmed after propensity score adjustment. TAT and DAT did not differ as regards NACE rate (17% vs. 19%, P = 0.864) although, compared with TAT, DAT was associated with less major bleedings (2% vs. 5%, P = 0.014), confirmed after propensity score adjustment. In conclusion, in patients on OAC undergoing PCI, DOAC, compared with VKA, was associated with a significantly lower occurrence of NACE and DAT reduced bleedings compared with TAT.

Clinical outcomes of overlapping versus non-overlapping everolimus-eluting absorb bioresorbable vascular scaffolds: An analysis from the multicentre prospective RAI registry (ClinicalTrials.gov identifier: NCT02298413).

OBJECTIVES: To compare clinical outcomes of patients treated with overlapping versus non-overlapping Absorb BVS. BACKGROUND: Limited data are available on the clinical impact of stent overlap with the Absorb BVS bioresorbable stent. METHODS: We compared outcomes of patients receiving overlapping or non-overlapping Absorb BVS in the multicenter prospective RAI Registry. RESULTS: Out of 1,505 consecutive patients treated with Absorb BVS, 1,384 were eligible for this analysis. Of these, 377 (27%) were in the overlap group, and 1,007 (73%) in the non-overlap group. The most frequent overlap configuration was the marker-to-marker type (48%), followed by marker-over-marker (46%) and marker-inside-marker (6%) types. Patients of the overlap group had higher prevalence of multivessel disease and higher SYNTAX score, and required more frequently the use of intravascular imaging. At a median follow-up of 368 days, no difference was observed between overlap and non-overlap groups in terms of a device-related composite endpoint (cardiac death, TV-MI, ID-TLR) (5.8% vs. 4.1%, P = 0.20) or of a patient-related composite endpoint (any death, any MI, any revascularization) (15.4% vs. 12.5%, P = 0.18). Cardiac death (1.0% vs. 1.3%, P = 0.54), MI (4.5% vs. 3.6%, P = 0.51), TVR (4.5% vs. 3.6%, P = 0.51) and stent thrombosis (1.1 vs. 1.5%, P = 1.00) were also comparable between groups. When assessing outcomes of the overlap population according to overlap configurations used, no difference was observed in terms of the device- or patient-related composite endpoints. CONCLUSIONS: Outcomes of patients with or without overlapping BVS were comparable at mid-term follow-up despite higher angiographic complexity of the overlap subset. © 2017 Wiley Periodicals, Inc.

Radial versus femoral approach comparison in percutaneous coronary intervention with intraaortic balloon pump support: the RADIAL PUMP UP registry.

BACKGROUND: The role of intraaortic balloon pump (IABP) during percutaneous coronary intervention (PCI) in high-risk acute patients remains debated. Device-related complications and the more complex patient management could explain such lack of clinical benefit. We aimed to assess the impact of transradial versus transfemoral access for PCI requiring IABP support on vascular complications and clinical outcome. METHODS: We retrospectively analyzed 321 consecutive patients receiving IABP support during transfemoral (n = 209) or transradial (n = 112) PCI. Thirty-day net adverse clinical events (NACEs) (composite of postprocedural bleeding, cardiac death, myocardial infarction, target lesion revascularization, and stroke) were the primary end point, with access-related bleeding and hospital stay as secondary end points. RESULTS: Cardiogenic shock and hemodynamic instability were the most common indications for IABP support. Cumulative 30-day NACE rate was 50.2%, whereas an access site-related bleeding occurred in 14.3%. Patients undergoing transfemoral PCI had a higher unadjusted rate of NACEs when compared with the transradial group (57.4% vs 36.6%, P < .01), mainly due more access-related bleedings (18.7% vs 6.3%, P < .01). Such increased risk of NACEs was confirmed after propensity score adjustment (hazard ratio 0.57 [0.4-0.9], P = .007), whereas hospital stay appeared comparable in the 2 groups. CONCLUSIONS: In this observational registry, high-risk patients undergoing PCI and requiring IABP support appeared to have fewer NACEs if transradial access was used instead of transfemoral, mainly due to fewer access-related bleedings. Given the inherent limitations of this retrospective work, including the inability to adjust for unknown confounders, further controlled studies are warranted to confirm or refute these findings.

Design of the PERSEO Registry on the management of patients treated with oral anticoagulants and coronary stent.

AIM: Percutaneous coronary intervention with stent implantation (PCI-S) in patients requiring chronic oral anticoagulant therapy (OAC) is associated with an increased risk of bleeding and ischemic complications. Different randomized studies showed a significant advantage of a double antithrombotic therapy and superiority of direct oral anticoagulant (DOAC) compared with warfarin, but real-world data are limited. Aim is to evaluate the antithrombotic management and clinical outcome of patients with an indication for OAC who undergo PCI-S in a 'real-world' setting. METHODS: The multicentre prospective observational PERSEO (PERcutaneouS coronary intErventions in patients treated with Oral anticoagulant therapy) Registry (ClinicalTrials.gov Identifier: NCT03392948) has been designed to enrol patients requiring OAC treated by PCI-S in 25 Italian centres. A target of at least 1080 patients will be followed for 1 year and data on thromboembolic and bleeding events and changes in antithrombotic therapy will be registered. The primary end point is a combined measure of efficacy and safety outcome (NACE), including major bleeding events and major adverse cardiac and cerebral events at 1-year follow-up in patients treated with DOAC (and dual or triple antiplatelet therapy) compared with the corresponding strategies with vitamin K antagonists. A secondary prespecified analysis has been defined to evaluate NACE in dual versus triple antithrombotic therapy after hospital discharge at 1-year follow-up. CONCLUSION: The PERSEO Registry will investigate in a 'real world' setting the safety and efficacy of DOAC versus warfarin and dual versus triple antithrombotic therapy in patients with indication for oral anticoagulant therapy who undergo PCI-S.

The PREHAMI (PREsillion™ in high-risk acute myocardial infarction) registry: in-hospital and long-term outcomes.

OBJECTIVES: To evaluate the efficacy of the new Cobalt-Chromium (Co-Cr) Presillion™ stent for the treatment of high-risk acute myocardial infarction (MI) patients. BACKGROUND: Percutaneous coronary intervention (PCI) with stent represents the gold standard treatment for acute MI. METHODS AND RESULTS: We enrolled patients with high-risk acute MI (either ST-segment elevation MI or non-ST-segment elevation MI) treated with PCI using a new Co-Cr bare metal stent with closed cells design and limited balloon compliance. We considered high-risk features as one of the following: age ≥ 70 years, ejection fraction ≤ 35%, glomerular filtration rate ≤ 60 mL/min, diabetes mellitus, rescue PCI, or chronic atrial fibrillation or other conditions requiring long-term oral anticoagulation therapy. Primary outcome of the study was rate of major adverse cardiac events (MACE) defined as all-cause death, new MI, and target-vessel revascularization. A total of 129 consecutive patients were enrolled (69 ± 11 years, 74% men): 71 (55%) patients with ST-segment elevation MI and 58 (45%) patients with non-ST-segment elevation MI. A total of 153 vessels (169 lesions and 179 stents) were treated. The device success rate was high (98.8%). In-hospital MACE rate was 5.4% mainly because of death associated with the acute MI. At 1-year follow-up, the MACE rate was 17.3%, with 11% all-cause death (7.9% of cardiac origin), 0.6% of stent thrombosis, and 4.6% target-vessel revascularization. CONCLUSIONS: The use of the Co-Cr Presillion stent in patients with high-risk acute MI treated invasively seems to be safe and efficacious with optimal deliverability and good long-term outcomes and represents a good option in the treatment of these patients.

Clinical findings after bioresorbable vascular scaffold implantation in an unrestricted cohort of patients with ST-segment elevation myocardial infarction (from the RAI registry).

BACKGROUND: The bioresorbable vascular scaffold (BVS) technology may be an appealing option in ST-segment elevation myocardial infarction (STEMI) patients. However, the available evidence on its use in this challenging subset is limited. METHODS: Registro Absorb Italiano (RAI) is a multicenter, prospective registry that aims to assess BVS performance through a 5-year follow-up of all consecutive patients who undergone at least 1 successful BVS implantation. As a part of it, a subgroup analysis in STEMI patients was performed and the outcomes of this cohort compared to the remaining population (defined as "non-STEMI") are reported here. RESULTS: Among the 1505 patients enrolled, 317 (21.1%) had STEMI on admission. Among those, 232 (73.2%) underwent primary percutaneous coronary intervention (PCI) within 12 h from symptom onset; 64 (20.2%) were late-comers (>12 h); 16 (5%) underwent PCI after successful thrombolysis while 5 (1.6%) underwent rescue-PCI. At a median follow-up time of 12 months (IQR 6-20 months) no differences were noticed between STEMI and "non-STEMI" groups in terms of device-oriented composite endpoint (4.1% vs. 5.6%; p = 0.3) and its singular components: ischemia-driven target lesion revascularization (3.2% vs. 3.6%; p = 0.7), target-vessel myocardial infarction (3.2% vs. 2.8%; p = 0.7) and cardiac death (0.6% vs. 0.6%; p = 0.9). The rate of definite/probable scaffold thrombosis (ScT) was numerically higher but not significant in the STEMI group (2.5% vs. 1.3%; p = 0.1). CONCLUSIONS: BVS implantation in an unrestricted cohort of STEMI patients is associated with a numerically higher rate of ScT compared to the non-STEMI group. Further studies exploring the potential clinical impact of a pre-specified BVS implantation strategy in this high-risk clinical setting are needed.

Registro Absorb Italiano (BVS-RAI): an investigators-owned and -directed, open, prospective registry of consecutive patients treated with the Absorb™ BVS: study design.

BACKGROUND: The Absorb™ BVS is a bioresorbable, everolimus-eluting scaffold approved and marketed for coronary use. Published data on long-term results after treatment are limited to a small number of patients, most of them with elective PCI of simple lesions. The importance of scaffold resorption is variably appreciated among cardiologists, and indications for use from health technology assessment bodies or guidelines are missing. Instruments are needed to collect, share and assess the experience being accumulated with this new device in several centres. METHODS/DESIGN: The BVS-RAI Registry is a spontaneous initiative of a group of Italian interventional cardiologists in cooperation with Centro di Ricerche Farmacologiche e Biomediche "Mario Negri" Institute, and is not recipient of funding or benefits originating from the BVS manufacturer. It is a prospective registry with 5-year follow-up of all consecutive patients who have undergone successful implantation of 1 or more coronary BVS following the indications, techniques and protocols used in each of the participating institutions. Outcome measures are BVS target lesion failure within one year and device-oriented major adverse cardiac events within 5years. The registry started in October 2012 and will extend enrolment throughout 2015, with the aim to include about 1000 patients. ClinicalTrials.gov identifier is CT02298413. CONCLUSIONS: The BVS-RAI Registry will contribute observational knowledge on the long-term safety and efficacy of the Absorb™ BVS as used in a number of Italian interventional centres in a broad spectrum of settings. Unrewarded and undirected consecutive patient enrolments are key-features of this observation, which is therefore likely to reflect common clinical practice in those centres.

Transulnar sheathless percutaneous coronary intervention during bivalirudin infusion in high-risk elderly female with non-ST segment elevation myocardial infarction.

Due to the ageing population and raised life expectancy, elderly patients are increasingly referred for percutaneous coronary intervention (PCI) during acute coronary syndromes (ACS). Bleeding complications are not infrequent during ACS, occurring in 2-5% of patients with prognostic and economic consequences. In particular, periprocedural bleeding and vascular complications are associated with worse clinical outcome, prolonged hospital stay and increased short- and long-term mortality, especially in elderly patients with acute coronary syndromes. We report the case of an 83-year old female referred to our hospital because of non-ST segment elevation myocardial infarction with high bleeding risk and unsuitable radial artery undergoing tran-sulnar sheathless PCI during bivalirudin infusion. The clinical, technical, pharmacological and prognostic implications are discussed.
