BACKGROUND: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is a simple risk model able to predict early and late mortality after cardiac surgery. Recent data suggest that this score may also predict early clinical outcome after percutaneous coronary intervention (PCI). Data regarding EuroSCORE usefulness to predict late outcome after PCI in unselected patients are lacking. METHODS: EuroSCORE was prospectively assessed in consecutive patients undergoing PCI during 18 months. The primary end-point was cardiac mortality during the follow-up after PCI. Total mortality was the secondary end-point. Kaplan-Meyer analyses were performed dividing the study population in three subgroups according to the additive EuroSCORE algorithm (low risk group: EuroSCORE 0-2; medium risk group: EuroSCORE 3-5; high-risk group: EuroSCORE ≥ 6). Receiver operating characteristics (ROC) curve and landmark analysis on cardiac mortality after 30 days were performed. RESULTS: The study population comprised 1170 patients undergoing PCI. Mean follow-up duration was 633 days (range: 365-1000 days). Cardiac mortality was 2%; 2.4%; 13.2% in patients with low, medium and high EuroSCORE respectively. Kaplan-Meyer survival curves for cardiac death differed significantly between EuroSCORE groups (p<0.0001). The area under the ROC curve for the prediction of cardiac death was 0.77. Similar results were obtained for total mortality. At landmark analysis starting 30 days after PCI, EuroSCORE groups were significantly associated with different survival in the long term (P=0.014). CONCLUSION: EuroSCORE risk model can be efficiently utilized to predict late mortality in consecutive, unselected, patients undergoing PCI.

To investigate a possible independent predictive role of systemic inflammation markers on renal function after renal artery stenting.

Coronary aneurysmatic dilatation may be localized to a segment or may involve multiple segments. We herein report a case of a diffuse aneurysmatic dilatation of the right coronary artery.

OBJECTIVES: To investigate a possible independent predictive role of systemic inflammation markers on renal function after renal artery stenting. BACKGROUND: An elevated baseline serum creatinine has previously been shown to be the strongest predictor of improved renal function after percutaneous renal artery stenting. The inflammatory system is implicated in every stage of chronic kidney disease, and we hypothesized an additional value of markers of systemic inflammation in predicting response after renal artery stenting. METHODS: This single center, prospective study includes 62 consecutive patients with chronic kidney disease at stage ≥3 or resistant hypertension who underwent stent placement for 74 angiographically significant atherosclerotic renal lesions. Inflammatory markers, including serum C-reactive protein (CRP), erythrocyte sedimentation rate, and white blood cell count were determined prior to renal angioplasty and related to changes in renal function at follow-up. RESULTS: Six-month clinical follow up was completed in 57 patients. Overall, median serum creatinine concentration exhibited a non significant reduction from 1.40mg/dl (quartiles: 1.20, 1.75mg/dl) at baseline to 1.30mg/dl (quartiles: 1.1, 1.55mg/dl) at 6months (p=0.17). Significant multivariate independent predictors of decreased creatinine included higher baseline serum creatinine levels (adjusted OR per quartile increment, 2.5 [1.3 to 4.7], p=0.004) and lower C-reactive protein levels (adjusted OR per quartile increment 0.39 [0.19 to 0.82], p=0.013). CONCLUSIONS: Patients with higher serum creatinine and lower CRP derive the most benefit from renal artery stenting.

Trans-radial approach (TRA) reduces vascular access-site complications but has some technical limitations. Usually, TRA procedures are performed using 5 Fr or 6 Fr sheaths, whereas complex interventions requiring larger sheaths are approached by trans-femoral access.

Optimal management of patients needing non-cardiac surgery after coronary stenting has not been established. Objective. To assess the perioperative outcome of patients undergoing non-cardiac surgery after coronary bare-metal stent (BMS) or drug-eluting stent (DES) implantation. METHODS: We enrolled consecutive patients undergoing non-cardiac surgery (up to 2008) after coronary stenting in a single-center registry, prospectively registering clinical and procedural data about revascularization and retrospectively recording surgical details, perioperative therapy and in-hospital outcome after surgery. At our institution, we implant BMS for planned surgery at time of revascularization, and use antiplatelet therapy for surgery required within 1 month of BMS or within 12 months of DES implantation. The primary endpoint was defined as perioperative occurrence of major adverse events, both cardiovascular (death, myocardial infarction, stent thrombosis and repeated revascularization) and hemorrhagic (bleeding requiring transfusions or surgical hemostasis). RESULTS: We enrolled 101 patients: 70 treated with BMS (group 1) and 31 with DES (group 2). The mean interval between stenting and surgery was 288 days. The average number of antiplatelet drugs used during the operative period was higher in group 2 than group 1 (p = 0.02). Fifteen patients (15%) experienced major adverse events (5.9% had non-ST elevation myocardial infarction, 12% received blood transfusions), without a significant difference between the two groups (p = 0.72). At multivariate analysis, the predictor of primary endpoint was time interval between stenting and surgery (p = 0.022). CONCLUSION: We found similar outcomes for non-cardiac surgery after coronary stenting when BMS were selected for planned surgery and dual antiplatelet therapy was used, if indicated, during the operative period.

OBJECTIVE: To assess the clinical outcome of unselected patients undergoing drug-eluting stent (DES) implantation on bifurcated lesions using a "provisional T And small Protrusion (TAP)" stenting strategy. METHODS: Consecutive patients undergoing DES implantation on one major bifurcation lesion were treated by main-vessel (MV) stenting, followed (if needed) by side-branch (SB) rewiring (with a "pullback" technique) and kissing balloon. SB stenting was performed according to the TAP-technique in selected cases. The endpoint of the study was a 12-month incidence of major adverse cardiac events (MACE) defined as cardiac death, myocardial infarction (MI), stent thrombosis and target vessel revascularization (TVR). RESULTS: The study population included 266 patients (9% unprotected left main). Only 19 patients (7.1%) (with more complex angiographic features) received stents in both the MV and SB using the TAP-technique. Overall, 22 (8.2%) patients had MACE at 1 year. Observed, non-hierarchical MACE were: 1 (0.4%) cardiac death, 11 (4.1%) MI, 2 probable stent thromboses and 12 (4.5%) TVRs. Postprocedural troponin T increase and adverse events up to 12 months were similar between patients treated by MV stenting only or double stenting. CONCLUSIONS: In unselected patients undergoing DES implantation on bifurcated lesions, a provisional TAP-stenting strategy (with a low rate of SB stenting) appears to be safe and effective.
