    ABSTRACT: 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.

    ABSTRACT: It remains undefined if transradial coronary angiography from a right or left radial arterial approach differs in real-world practice. To address this issue, we performed a subanalysis of the PREVAIL study. The PREVAIL study was a prospective, multicenter, observational survey of unselected consecutive patients undergoing invasive cardiovascular procedures over a 1-month observation period, specifically aimed at assessing the outcomes of radial approach in the contemporary real world. The choice of arterial approach was left to the discretion of the operator. Prespecified end points of this subanalysis were procedural characteristics. Of 1,052 patients consecutively enrolled, 509 patients underwent transradial catheterization, 304 with a right radial and 205 with a left radial approach. Procedural success rates were similar between the 2 groups. Compared to the left radial group, the right radial group had longer procedure duration (46 ± 29 vs 33 ± 24 minutes, p <0.0001) and fluoroscopy time (765 ± 787 vs 533 ± 502, p <0.0001). At multivariate analysis, including a parsimonious propensity score for the choice of left radial approach, duration of procedure (beta coefficient 11.38, p <0.001) and total dose-area product (beta coefficient 11.38, p <0.001) were independently associated with the choice of the left radial artery approach. The operator's proficiency in right/left radial approach did not influence study results. In conclusion, right and left radial approaches are feasible and effective to perform percutaneous procedures. In the contemporary real world, however, the left radial route is associated with shorter procedures and lower radiologic exposure than the right radial approach, independently of an operator's proficiency.

    ABSTRACT: To assess: the reasons behind an operator choosing to perform radial artery catheterisation (RAC) as against femoral arterial catheterisation, and to explore why RAC may fail in the real world. A pre-determined analysis of PREVAIL study database was performed. Relevant data were collected in a prospective, observational survey of 1,052 consecutive patients undergoing invasive cardiovascular procedures at nine Italian hospitals over a one month observation period. By multivariate analysis, the independent predictors of RAC choice were having the procedure performed: (1) at a high procedural volume centre; and (2) by an operator who performs a high volume of radial procedures; clinical variables played no statistically significant role. RAC failure was predicted independently by (1) a lower operator propensity to use RAC; and (2) the presence of obstructive peripheral artery disease. A 10-fold lower rate of RAC failure was observed among operators who perform RAC for > 85% of their personal caseload than among those who use RAC < 25% of the time (3.8% vs. 33.0%, respectively); by receiver operator characteristic (ROC) analysis, no threshold value for operator RAC volume predicted RAC failure. A routine RAC in all-comers is superior to a selective strategy in terms of feasibility and success rate.

    ABSTRACT: Myocardial revascularization with drug-eluting stents (DESs) is emerging as an alternative to conventional coronary artery bypass surgery in patients with multivessel coronary artery disease (MV-CAD). First-generation DESs have yielded equivalent safety results at mid-term compared with surgery, but inferior efficacy in preventing the recurrence of ischemic symptoms. The outcome of percutaneous coronary intervention with a second-generation everolimus DES as compared with a paclitaxel DES in patients with MV-CAD has not been established. The aim of the study is the assessment of the efficacy and performance of the XIENCE V everolimus-eluting stent in the treatment of de-novo coronary artery lesions in patients with MV-CAD. The study is composed of two parts: a prospective, double arm, randomized multicenter trial to assess the angiographic efficacy of the XIENCE V everolimus-eluting coronary stent system (EECSS) compared with the Taxus Liberté Paclitaxel Eluting Coronary Stent System (Taxus Liberté Stent) and a prospective, open-label, single arm, controlled registry to analyze the clinical efficacy and safety of XIENCE V EECSS at mid-term and long-term follow-up in patients treated for MV-CAD. For the EXECUTIVE randomized trial, the primary endpoint is in-stent late lumen loss at 9 months. For the EXECUTIVE registry, the primary endpoint is a composite of all death, myocardial infarction (Q-wave and non-Q-wave), and ischemia-driven target vessel revascularization at 12 months. The study will be conducted at 30 study centers in Italy and 600 patients will be enrolled in total: 200 patients will be enrolled (1: 1) in the randomized trial and 400 patients will enter the registry. It was calculated that, assuming a mean in-stent late lumen loss of 0.20 +/- 0.41 mm in the XIENCE V EECSS arm and 0.30 +/- 0.53 mm in the Taxus Liberté stent arm, and a noninferiority margin delta of 0.12 (according to the SPIRIT III results), the analysis of 81 lesions per arm would provide over 90% power. Therefore, 200 patients will be enrolled to account for dropouts. The present study is expected to provide as yet unavailable information about the performance of second-generation stents in the specific setting of patients with MV-CAD.

    ABSTRACT: To obtain a "snapshot" view of access-specific percutaneous cardiovascular procedures outcomes in the real world. Multicentre, prospective study performed over a 30-day period. Nine hospitals with invasive cardiology facilities, reflecting the contemporary state of healthcare. Unselected consecutive sample of patients undergoing any percutaneous cardiovascular procedure requiring an arterial access. Percutaneous cardiovascular procedures by radial or femoral access The primary outcome was the combined incidence of in-hospital (a) major and minor haemorrhages; (b) peri-procedural stroke; and (c) entry-site vascular complications. The secondary outcome was the combined incidence of in-hospital death and myocardial infarction/reinfarction. For analysis purposes, outcomes were allocated to arterial access-determined study arms on an intention-to treat basis. Multivariable analysis adjusted using propensity score was performed to correct for selection bias related to arterial site. A total of 1052 patients were enrolled: 509 underwent radial access and 543 femoral access. In both groups, 40% underwent a coronary angioplasty. Relative to femoral access, radial access was associated with a lower incidence both of primary (4.2% vs 1.96%, p = 0.03, respectively) and secondary endpoints (3.1% vs 0.6%, p = 0.005, respectively). Multivariate analysis, adjusted for procedural and clinical confounders, confirmed that intention-to-access via the radial route was significantly and independently associated with a decreased risk both of primary (OR 0.37, 95% CI 0.16 to 0.84) and secondary endpoints (OR 0.14, 95% CI 0.03 to 0.62). Our study indicates strikingly better outcomes of percutaneous cardiovascular procedures with radial access versus femoral access in contemporary, real-world clinical settings.

    ABSTRACT: The follow-up strategies after percutaneous coronary intervention (PCI) have relevant clinical and economic implications. The purpose of this prospective observational multicenter study was to evaluate the effect of clinical, procedural and organizational variables on the execution of functional testing (FT) and planned coronary angiography (CA) after PCI, and to assess the impact of American College of Cardiology (ACC)/American Heart Association (AHA) guidelines on clinical practice. Four hundred twenty consecutive patients undergoing PCI were categorized as class I, IIB and III indications for follow-up FT according to ACC/AHA guidelines recommendations. Furthermore, all patients were grouped according to the presence or absence of FT and/or planned CA over 12 months after PCI. Multivariable analysis was used to assess the potential predictors of test execution. During the 12-month follow-up at least one test was performed in 72% of patients with class I indication, 63% of patients with class IIB indication and 75% of patients with class III indication (p=ns). A total of 283 patients (67%) underwent testing. The use of tests was associated with younger age (R.R. 0.94, C.I. 0.91+/-0.97, p<0.001), a lower number of diseased vessels (R.R. 0.60, C.I. 0.43+/-0.84, p=0.003), follow-up by the center performing PCI (R.R. 2.64, C.I. 1.43+/-4.86, p=0.002), and the specific center at which PCI was performed. Most asymptomatic patients completed their testing prematurely with respect to the risk period for restenosis. The use of FT and planned CA after PCI is unrelated to patient's symptom status, and depends on patient's age and logistics. ACC/AHA guidelines have no influence in clinical practice, and test timing is not tailored to the risk period for restenosis.
