Abstract
Background Transcatheter left atrial appendage occlusion (LAAO) is a valuable therapeutic option for stroke prevention in patients with atrial fibrillation (AF) at high bleeding risk. However, complex LAA anatomies sometimes preclude the adoption of commercially available LAAO devices. The design of a custom-made LAAO device is a promising strategy in these cases. However, few examples of custom-made devices in case of giant LAAs have been reported. Case summary An 85-year-old man with permanent AF with CHA2DS2-VASc 4 and recurrent active gastrointestinal major bleedings was referred for transcatheter LAAO at Parma University Hospital after multidisciplinary team evaluation. Pre-procedural coronary computed tomography angiography revealed a giant windsock LAA, with a maximum ostium diameter of 44 mm, a landing zone diameter of 34 mm, and maximal length of 49 mm. Patient's management was particularly challenging given that available LAAO devices were too small to completely exclude the LAA. In accordance with the manufacturer, a custom-made LAmbre™ Closure System (Lifetech Scientific, Shenzhen, China), which specifically fitted with patient's LAA anatomy, was designed and successfully deployed under transoesophageal echocardiography (TEE) and fluoroscopic guidance. Periprocedural TEE confirmed the appropriate position of the device and the absence of peri-device leaks. No adverse ischaemic and haemorrhagic events were reported at 3-months follow-up. Discussion We present a case of a successful transcatheter LAAO procedure by deploying a custom-made LAmbre device 38/46 mm to mechanically exclude a giant windsock LAA. This case illustrates the effectiveness of a custom-made device strategy, which potentially enables the closure of all complex LAA anatomies.

Abstract
OBJECTIVES Transcatheter patent foramen ovale closure lowers recurrent stroke in patients with cryptogenic stroke or transient ischemic attack with an indication for closure. However, the incidence of recurrent stroke is not negligible and underlying pathophysiology remains largely unknown. We sought to evaluate the prevalence of recurrent ischemic neurological events and to assess its predictors after transcatheter patent foramen ovale closure. METHODS We enrolled consecutive patients who underwent patent foramen ovale closure for secondary prevention of neurological ischemic events at the University Hospital of Parma between 2006 and 2021. Clinical and procedure-related features were collected for each patient. The incidence of recurrent ischemic neurological events was assessed at follow-up. RESULTS We enrolled a total of 169 patients with mean Risk of Paradoxical Embolism score at hospital admission of 6.4 ± 1.5. The primary indication was previous cryptogenic stroke (94 [55.6 %] subjects), followed by transient ischemic attack (75 [44.4 %]). Among patients with complete outcome data (n= 154), after a median follow-up of 112 months, recurrent cerebral ischemia occurred in 13 [8.4 %], with an annualized rate of 0.92/100 patients. The presence of obesity [OR 5.268, p = 0.018], Risk of Paradoxical Embolism score < 7 [OR 5.991, p = 0.035] and migraine [OR = 5.932 p = 0.012] were independent positive predictors of recurrent stroke/ transient ischemic attack after patent foramen ovale closure. CONCLUSIONS The presence of obesity, Risk of Paradoxical Embolism score < 7 and migraine were independent positive predictors of recurrent ischemic neurological events after patent foramen ovale closure.

Abstract
BACKGROUND Spontaneous coronary artery dissection (SCAD) often presents with acute coronary syndrome and underlying pathophysiology involves the interplay between predisposing factors and precipitating stressors, such as emotional and physical triggers. In our study we sought to compare clinical, angiographic and prognostic features in a cohort of patients with SCAD according to the presence and type of precipitating stressors. METHODS Consecutive patients with angiographic evidence of SCAD were divided into three groups: patients with emotional stressors, patients with physical stressors and those without any stressor. Clinical, laboratoristic and angiographic features were collected for each patient. The incidence of major adverse cardiovascular events, recurrent SCAD and recurrent angina was assessed at follow-up. RESULTS Among the total population (64 subjects), 41 [64.0%] patients presented with precipitating stressors, including emotional triggers (31 [48.4%] subjects) and physical efforts (10 [15.6%] subjects). As compared with the other groups, patients with emotional triggers were more frequently female (p = 0.009), had a lower prevalence of hypertension (p = 0.039] and dyslipidemia (p = 0.039), were more likely to suffer from chronic stress (p = 0.022) and presented with higher levels of C-reactive protein (p = 0.037) and circulating eosinophils cells (p = 0.012). At a median follow-up of 21 [7; 44] months, patients with emotional stressors experienced higher prevalence of recurrent angina (p = 0.025), as compared to the other groups. CONCLUSIONS Our study shows that emotional stressors leading to SCAD may identify a SCAD subtype with specific features and a trend towards a worse clinical outcome.

Abstract
Abstract
Introduction
Cardiac arrest secondary to a spontaneous coronary artery dissection (SCAD) represents a challenging scenario. It deserves specific considerations due to the dramatic presentation and the need for secondary sudden cardiac death prevention.
Methods
We collected clinical data of four women admitted during the last two years in the Coronary Care Unit of Parma University Hospital, whose presentation of SCAD were cardiac arrest due to ventricular fibrillation.
Results
Three patients survived the acute phases. One patient, being considered at high risk of SCAD recurrence, received a subcutaneous implantable cardioverter-defibrillator (S-ICD). Acute management of cardiac arrest related to SCAD deserves specific considerations. Our case series illustrates the importance of prompt resuscitation manoeuvres and early defibrillation. We propose a flow chart of management of cardiac arrest in patient with suspect of SCAD. Evaluating risk of SCAD recurrence and sudden cardiac death The management of SCAD patients complicated by malignant ventricular arrhythmias and cardiac arrest is challenging. Looking at published registries, it appears that SCAD patients are more likely to suffer from ventricular arrythmia or sudden cardiac death than non-SCAD MI patients. The risk-benefit ratio of ICD implantation in these patients remain uncertain . Evaluation of scar burden with CMR can help stratify the global arrhythmic risk, especially as extensive myocardial scar with a residual impaired LVEF increases the risk of future arrhythmic events. In our series, only one patient underwent S-ICD implantation, and the decision was mainly driven by the finding of underlying arteriopathy affecting other vascular territories, suggesting a potentially higher rate of SCAD recurrence. For this particular subset of patients, we propose an algorithm that combines predisposing factors and myocardia injury quantification data that could be useful for the estimate of the risk of malignant arrythmias, as well as the risk of recurrence of SCAD, but needs to be validated in larger case studies.
Conclusions
The acute management of cardiac arrest related to SCAD deserves specific consideration. The residual myocardial damage, predisposing and precipitants factors should be evaluated in order to estimate the SCAD recurrence and sudden cardiac death risks.

Abstract
Abstract
Background
Transcatheter patent foramen ovale (PFO) closure is an effective therapy in patients with cryptogenic stroke (CS) or transient ischemic attack (TIA) and evidence of PFO. However, the incidence of recurrent cerebral ischemia is not negligible and underlying pathogenic mechanisms remain largely unknown. We sought to evaluate the magnitude of the problem and to assess predictors of recurrent stroke/TIA after transcatheter PFO closure.
Methods
We enrolled non-randomized consecutive patients who underwent PFO closure for secondary prevention of neurological ischemic events at the University Hospital of Parma between 2004 and 2021. Clinical, echocardiographic and procedure-related features were collected for each patient. The incidence of recurrent ischemic neurological events was assessed at follow-up.
Results
We enrolled a total of 154 patients. The primary indication for PFO closure was previous stroke (85 [55.2%] subjects) and a third of patients (51 [33.1%]) suffered from migraine, 22 [14.3%] with and 29 [18.8%] without aura. Moreover, mean Risk of Paradoxycal Embolism (ROPE) score at hospital admission was 6.4 ± 1.5. After a median follow-up of 112 months, the incidence of recurrent cerebral ischemia occurred in 13 [8.4%] patients, with an annualized rate of 0.92/100 patients. The presence of migraine, obesity and ROPE < 7 were independent positive predictors of recurrent stroke/TIA.
Conclusion
The presence of obesity, a familiar history of CVD, ROPE < 7 and migraine were independent positive predictors of recurrent ischemic neurological events after PFO closure.

Abstract
AIMS Spontaneous coronary artery dissection (SCAD) is an emerging cause of acute myocardial infarction (AMI) in young women without a typical cardiovascular risk profile. Knowledge on SCAD is based on observational studies and is still scarce. The aim of this monocentric observational study was to evaluate the predisposing factors, clinical features and prognosis of SCAD patients. METHODS Between 2013 and 2020, 58 patients with angiographic diagnosis of SCAD were identified in our centre with an overall prevalence of 0.9% among patients admitted for AMI (58 of 6414 patients). RESULTS The mean age was 54 ± 11 years and the majority were women (n = 50, 86%) with one or fewer cardiovascular risk factors (n = 35, 60%). The prevalence of Fibromuscolar Dysplasia (FMD) was 39% (7 of 18 screened patients). The rate of major adverse cardiovascular and cerebrovascular events (MACCEs) was used to assess the prognosis. Out-of-hospital cardiac arrest because of ventricular fibrillation was observed in four (7%) patients. The majority of patients (n = 51, 88%) were treated conservatively without revascularization. The in-hospital and 30-day clinical course was uneventful in most patients (n = 54, 93%) with two cardiac deaths. During a median follow-up of 12 months, there were no further deaths. The global rate of SCAD recurrence was significant (n = 8, 14%) but predictors have not been identified. CONCLUSION Although overall survival seems good, SCAD is a potentially malignant, not rare disease, which can present with sudden cardiac death and not uncommon recurrence. Prognostic stratification and optimal management of SCAD patients remain to be defined.

Abstract
Abstract
Aims
Oral anticoagulation (OAC) is the cornerstone therapy for stroke prevention in patients with atrial fibrillation (AF). However, a not negligible proportion of AF patients experiences major bleeding events or is affected by concomitant disorders that represent a contraindication for OAC. Left atrial appendage occlusion (LAAO) has emerged as an effective strategy to minimize the risk of thromboembolism in AF patients (without moderate/severe mitral stenosis or mechanical prosthetic heart valves) that are poor candidates for OAC. After the procedure variable regimens of antithrombotic therapy are prescribed, in order to provide protection and prevent device-related thrombus (DRT). The optimal post-procedural antithrombotic strategy remains to be assessed. Therefore, we aim to evaluate the safety and efficacy of LAAO procedure and the relationship between antiplatelet therapy and outcomes at long-term follow-up.
Methods and results
We conducted a retrospective observational study including consecutive AF patients who underwent LAAO at Azienda Ospedaliero-Universitaria of Parma from October 2010 to June 2021. The incidence of major ischaemic events [DRT, ischaemic stroke, transient ischaemic attack (TIA) and systemic embolism], Bleeding Academic Research Consortium major bleeding events and net adverse clinical events (major ischaemic + bleeding events) were assessed at follow-up. We enrolled 130 patients [median age 77 years (73; 81)] characterized by both high ischaemic (mean CHA2DS2-VASc 4.48) and bleeding risk (mean HAS-BLED 3.24). Technical procedure success was achieved in 123 (94.6%). Thirty-nine (31.7%) patients were discharged on short (≤1 month)-dual antiplatelet therapy (DAPT); 35 (28.5%) on long-DAPT (1–12 months) and 49 (39.8%) on single antiplatelet therapy (SAPT). Antiplatelet therapy was chosen after multidisciplinary discussion on the basis on the hemorrhagic risk [mean HAS-BLED 3.55; 3.11; 2.97 (P = 0.038) in SAPT, short-DAPT and long-DAPT groups respectively], while no differences were observed in ischaemic risk between the three groups. Clinical follow-up was completed in 119 (98.2%) of successfully implanted patients. After a median follow-up of 31 ± 16 months, 24 (20.2%) patients had a major adverse event: 11 (9.2%) ischaemic events [8 (6.7%) strokes and 3 (2.5%) TIA] and 13 (10.9%) major bleedings. Patients on short-DAPT had a significantly lower occurrence of major bleedings [0 vs. 4 (11.4%) on long-DAPT vs. 9 (18.4%) on SAPT; P = 0.033] and net adverse clinical events [3 (7.7%) vs. 7 (20.0%) on long-DAPT vs. 14 (28.6%) on SAPT; P = 0.005] compared to the other two groups, while no difference was observed in the incidence of major ischaemic events [3 (7.7%) on short-DAPT vs. 3 (8.6%) on long-DAPT vs. 5 (10.2%) on SAPT; P = 0.340].
Conclusions
In our cohort of AF patients with a contraindication for OAC therapy, LAAO showed high procedural success; however, long-term major ischaemic and bleeding events were not negligible. Short-DAPT therapy turned out to be the best antiplatelet regimen regarding net ischaemic-hemorrhagic balance. Evidence from well-designed randomized trials would be desirable to guide a tailored approach in the selection of post-procedural antithrombotic regimens.

Abstract
The incidence of complications of coronary perforation varied significantly among studies probably due to population heterogeneity and interventional techniques applied in each centre. Free wall rupture, cardiac tamponade and miocardial infarction are the most feared. The treatment of perforation remains a challenge of every cath- lab team. The management strategies range from observation to urgent operation depending on patient's hemodynamic status, severity and location of the perforation, coronary anatomy, interventional practice and equipment in each centre and operators' skills on-site. In this case an extracorporeal circulation and cardioplegic arrest with anterograde hot blood cardioplegia was done. A composite Dacron with autologous pericardium patch was used for left ventricular free wall rupture repair and the geometry of the left ventricle was restored. Subsequently aorta was declamped; the patient was weaned from CEC and a good spontaneous hemodynamic was recovered.

Abstract
Atrial fibrillation is the most common cardiac arrhythmia worldwide and represents a major risk factor for cerebral embolic stroke. The standard therapy in the prevention of stroke is oral anticoagulation therapy (OAT). However, a considerable number of patients are unable to tolerate chronic OAT. Among these are patients with hereditary hemorrhagic telangiectasia. We present the case of a female patient affected by Rendu-Osler-Weber disease and atrial fibrillation with indication to OAT. Because of worsening bleeding episodes, this therapy was discontinued and we decided to perform percutaneous left atrial appendage occlusion (LAAO) with implantation of the WATCHMAN device (Boston Scientific). Post-procedural antithrombotic therapy with clopidogrel 75 mg/day was prematurely interrupted after 3 weeks because of significant bleeding recurrences. After 12 months, the patient is in good health, with rare episodes of minor bleeding. Echocardiography showed a well-positioned LAAO device, without thrombotic apposition. In conclusion, this case confirms that percutaneous LAAO is a valid therapeutic alternative to OAT and represents a successful strategy in high bleeding risk patients with a contraindication to OAT. By thorough assessment, a single antiplatelet therapy after device implantation and for a time-limited period might be considered, according to the latest recent evidence.

Abstract
Aim of the study was to compare four different strategies of dual antiplatelet therapy (DAPT) in patients with acute coronary syndromes (ACS) treated with PCI. DAPT with Clopidogrel, Ticagrelor and Prasugrel has proved to be effective in patients with ACS treated with percutaneous coronary intervention (PCI) by reducing major adverse cardiovascular outcomes (MACE). However, the effect of the different strategies in a real-world population deserves further verification. A retrospective analysis of 2404 discharged ACS patients treated with PCI was performed, with a median follow-up of 1 year. The study population was stratified in four drug treatment cohorts: ASA + Clopidogrel (A-C), ASA + Plavix (A-PLx), ASA + Ticagrelor (A-T), ASA + Prasugrel (A-P). We assessed the incidence of net adverse cardiovascular events (NACE): all-cause death, myocardial infarction (MI), target vessel revascularization (TVR), stroke and bleeding during follow-up. At 1-year, the use of A-C and A-PLx was associated with the highest cumulative incidence of NACE in comparison with A-T and A-P therapies (respectively 14.8 and 29.6% vs. 9.2 and 6%). This difference was mainly driven by the mortality and TVR outcomes. Considering selection bias and differences in the patients baseline characteristics, the association of A-T and A-P seems to be superior in comparison with a DAPT strategy of A-C and A-PLx in low risk ACS-PCI patients from real world. In our Region the prescription is consistent with guidelines recommendations and Clopidogrel and Plavix are still predominantly used in older patients with more comorbidities, and this could partially explain the inferiority of this association.

Abstract
We report the case of a 34-year-old female treated with radiotherapy and chemotherapy for non-Hodgkin lymphoma at the age of 16. The patient came to our attention because of progressive dyspnea on effort and a positive result on a pharmacologic stress echo test. Coronary angiography revealed focal critical ostial stenosis of the left main coronary artery. Considering the high surgical risk due to possible post-radiation thoracic adherence and the young patient age, she underwent successful stenting of the left main stenosis with drug-eluting stent, followed by an intravascular ultrasound-guided post-dilation and final kissing balloon inflation. The procedure was uncomplicated.Heart diseases are among the frequently seen long-term effects of chemo/radiotherapy used for lymphoma treatment. The pathogenesis of radiation-induced coronary artery disease is complex and not yet fully understood, the mechanism is multifactorial and likely involves direct damage from radiation exposure or mediated by inflammatory cytokine secretion. Surgery management is often challenging due to radiation sequences, and a percutaneous approach is therefore used. The risk of long-term radiotherapy damage depends on radiation dose and the field of exposure. Modern techniques with lower radiation exposure and smaller treatment volumes may reduce these risks in future.

Abstract
AIMS We sought to assess the impact of different oral P2Y12 receptor inhibitors on residual thrombus and reperfusion indexes in ST-segment elevation myocardial infarction patients enrolled in the COCTAIL II trial, which included 128 primary percutaneous coronary interventions randomized to intracoronary vs. intralesion abciximab bolus with or without thrombectomy. METHODS Patients were divided into three groups: clopidogrel (n = 44), prasugrel (n = 45) and ticagrelor (n = 39). Residual intra-stent thrombus was quantified by optical coherence tomography using both the number of cross-sections with thrombus area more than 10% and thrombus volume. Reperfusion indexes included thrombolysis in myocardial infarction (TIMI) flow, corrected TIMI frame count, myocardial blush grade (MBG) and complete ST-segment resolution (≥70%). RESULTS In the prasugrel group, optical coherence tomography depicted a lower percentage of cross-sections with residual thrombus area more than 10% [4.0 (1.0-8.5)], as compared with clopidogrel [8.0 (1.0-15.0), P = 0.011] and ticagrelor [7.0 (3.0-13.5), P = 0.026].A higher thrombus volume was found in the clopidogrel group 4.0 mm(2.7-6.2) as compared with the prasugrel group [2.8 mm(1.8-4.4), P = 0.023], whereas the other between-group comparisons yield no significant differences. The frequency of MBG 3 was higher in the prasugrel group (73.3%) as compared with clopidogrel (45.5%) and ticagrelor [(56.4%), P = 0.027]. Final TIMI flow, TIMI frame count and ST resolution were not significantly different across the three groups (P = 0.423, 0.179 and 0.848, respectively). At multivariate analysis, pretreatment with prasugrel was independently associated with MBG 3 (odds ratio = 3.93; 95% confidence interval = 1.01-15.39). CONCLUSION Prasugrel loading dose was associated with a lower percentage of cross-sections with residual thrombus area more than 10% as compared with both clopidogrel and ticagrelor, although intrastent thrombus volume was not significantly different between prasugrel and ticagrelor.The frequency of MBG 3 was the only reperfusion index that was significantly more prevalent in prasugrel treated group as compared with clopidogrel and ticagrelor groups.

Abstract
We report the case of a 65--year-old woman admitted for inferior ST-segment elevation myocardial infarction complicated by complete atrioventricular block. The patient was under treatment with a novel oral anticoagulant (NOAC, rivaroxaban) because of a history of recurrent idiopathic pulmonary embolism. Emergency angiography showed complete acute thrombotic occlusion of the right coronary artery. After manual thrombectomy, there was no angiographic evidence of underlying atherosclerosis, therefore no further percutaneous coronary intervention was performed. Subsequent clinical course was uneventful. Laboratory tests demonstrated the presence of a heterozygous mutation of the factor II gene (G20210A), confirming the clinical evidence of a thrombophilic state. As rivaroxaban seemed to be ineffective in preventing spontaneous coronary thrombosis in this patient, antithrombotic therapy was shifted to warfarin plus low-dose aspirin. No further ischemic events occurred during the 1-year follow-up. It can be hypothesized that factor Xa inhibition by NOACs, such as rivaroxaban, could be insufficient in case of a thrombophilic state due to thrombin mutation. A brief review of the current literature on use of NOACs in acute coronary syndromes is also reported.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) caused by intraluminal thrombus organization and fibrous stenosis or complete obliteration of pulmonary arteries, is a not rare but life-threatening complication of acute pulmonary embolism. The prognosis of medically treated patients with CTEPH is poor and worsens as pulmonary hypertension exacerbates. We describe the case of a 43-years old with a history of progressive shortness of breath, hemoptysis, chest discomfort and syncope. Echocardiographic and imaging studies showed changes consistent with chronic thromboembolic pulmonary hypertension. Further work-up showed only moderate increase of homocysteine level with negative features for lupus and others primary thrombophilic disease. The patient was managed adequately with thrombolytic and inotropic therapy; oral anticoagulation was started with improvement of his clinical status and was screened for pulmonary thrombo endarterectomy, but he refused. The case presented despite its evolution 'temporarily' positive perhaps related to the reduction of hemodynamic overload through bronchial arteries, reiterates the importance of early surgical intervention, before it establishes the hypertensive vasculopathy. Abnormal pulmonary function at rest and after exercise stress test associated to non invasive echocardiographic measurements are an excellent tool to identify the bad prognosis patients in CTEPH. We discuss the pathophysiology and conclude that in selected cases, pulmonary thromboendarterectomy is the best therapy, but only if executed early.

Abstract
BACKGROUND Pulmonary arterial hypertension (PAH) in patients with systemic sclerosis is associated with a poor prognosis, but this can be improved by early disease detection. Abnormal pulmonary and cardiac function can be detected early by means of echocardiography, whereas right heart catheterization is usually performed later. OBJECTIVES The purpose of this prospective study was to detect early the presence of pulmonary artery vasculopathy in patients with verified systemic sclerosis without significant pulmonary fibrosis, normal lung volumes and a mildly reduced lung diffusion capacity of carbon monoxide (DLCO). METHODS Nineteen consecutive female NYHA class I-II patients with scleroderma and a PAPs of < 35 mm/Hg measured by echocardiography, were enrolled between September 2007 and September 2009. They had a mean age of 51 +/- 13 years, body mass index of 25 +/- 5 kg/m2). They all underwent complete Doppler echocardiography, CPET, a pulmonary ventilation test (carbon monoxide lung diffusion, DLCO), HRCT. To investigate PAH by means of complete resting Doppler echocardiography estimates of systolic pulmonary artery pressure (PAPs) derived from tr icuspid regurgitation, mean PAP derived from pulmonary regurgitation, pulmonary vessel resistance (PVR) derived from the acceleration time of the pulmonary outflow tract (ACTpo), and right ventricular function derived from tricuspid annular plane systolic excursion (TAPSE). Right heart catheterisation was conducted only, if pulmonary hypertension was suggested by echocardiography and an abnormal ventilator test.The data are given as mean values +/- SD, unless otherwise stated. The correlations between the variables were analysed using Pearson's r coefficient, and the predictive value of the variables was calculated using linear regression analysis. A p value of > 0.05 was considered significant. RESULTS Right heart catheterization detected PAH in 15/19 patients; mean PAP was 30.5 mm/Hg and RVP 3.6 UW. Coronary angiography of the patients aged more than 55 years showed some evidence of significant coronary artery disease. Echocardiography showed high systolic PAP values (46 +/- 8 mmHg), whereas right ventricular function was normal (TAPSE 23 +/- 3 mm), and in line with the NYHA class. ACTpo was reduced in the patients with a systolic PAP of < 46 mm/Hg (p > 0.001) and positively correlated with DLCO (p > 0.001) and the hemodynamic data.There was a good correlation between ACTpo and PVR (hemodynamic data) (r = -0615; p > 0.01). CONCLUSIONS Although they need to be confirmed by studies of larger series of patients, our findings suggest that, in comparison with hemodynamic data, non-invasive echocardiographic measurements are an excellent means of identifying early-stage PAH.

Abstract
Until now only few data have been published regarding the role of computed tomography for the detection of coronary thrombosis in coronary artery ectasias. We report the case of a 49-year-old man who was admitted to our hospital for prolonged chest pain followed by syncope. An early coronary angiography, performed after electrocardiography, the evaluation of cardiac enzymes and echocardiography, was carried out and revealed a diffuse coronary artery ectasia, involving particularly the right coronary artery. In addition, the following day the patient underwent contrast-enhanced cardiac 64-slice computed tomography, which revealed the presence of an intraluminal thrombus in the distal tract of the right coronary artery. Therefore, he was put on anticoagulant therapy and was discharged 2 days later. In conclusion, in this case, computed tomography played an additional and complementary role to coronary angiography.

Abstract
AIM Elective percutaneous coronary intervention (PCI) of left main coronary artery disease remains an important challenge in interventional cardiology. Nonetheless, this procedure is useful for patients with significant left main stenosis who are candidates for revascularization but unsuitable for coronary artery bypass graft. In this study the Authors sought to evaluate the safety and long-term mortality of PCI of left main coronary artery disease. Secondary endpoints were to analyse long-term mortality in various categories (patients<75 years vs patients<75 years, males vs females, drug eluting stents [DES] vs bare metal stents [BMS]). METHODS Between January 2003 and December 2006, 131 patients who consecutively under-went PCI on left main stem were reviewed. The mean follow-up time was 14.0+/-10.8 months. Survival curves were plotted with the Kaplan-Meier method and compared with the Log-rank test. RESULTS The Kaplan-Meier curves did not show statistically significant differences in terms of all-cause mortality at follow-up between protected and unprotected left main coronary disease (12% vs 14% respectively, P=0.67). In the protected left main group, there was a significantly higher use of DES compared with unprotected left main group (59% vs 43%, P=0.02). CONCLUSION The data show that PCI for left main coronary disease is feasible, safe and with an acceptable long-term mortality rate in patients at high-surgical risk unsuitable for surgical revascularization.

Abstract
BACKGROUND AND OBJECTIVE The clinical and immunologic activities of interleukin-2 (IL-2) in cancer patients have been extensively studied and described; however, in most of these studies, IL-2 was administered by intravenous bolus or continuous infusion, while the immunologic effects of IL-2 given by the subcutaneous (s.c.) route have not yet been well studied. DESIGN AND METHODS The present study was aimed at evaluating the effects of IL-2, given at very low doses s.c. to patients with advanced renal cell carcinoma (RCC), on a number of immunologic parameters: number of total lymphocytes, number of CD4-, CD8-, CD25-positive cells, number of natural killer (NK) cells, titers of IL-2 soluble receptor (sIL-2R) and of C4, eosinophils, eosinophilic cationic protein (ECP) and eosinophilic protein X (EPX). Finally, a logistic regression model was performed to identify early immunologic parameters that correlate with a favorable or unfavorable treatment outcome. RESULTS Independently from the mere report of the changes induced by immunotherapy, the analysis showed that, within the pre-treatment model, a large eosinophil number predicts the failure of IL-2 treatment; in contrast, within the post-treatment model, high C4 serum titers and, again, a large number of circulating eosinophils predict immunotherapy failure. INTERPRETATION AND CONCLUSIONS As far as concerns C4, its negative predictive value could be related to the fact that it is an indirect index of macrophage activation; thus, even though macrophages release substances with antitumor activity, they can also stimulate the release of sIL-2R, which may compete for exogenous IL-2. Some authors have postulated that macrophages may even stimulate tumor cell growth, or impair NK activity. Despite a great amount of uncertainty concerning the role of eosinophils, in our study, blood eosinophilia predicts a poor response to immunotherapy in patients with advanced RCC, thus supporting previous observations from our own group.

Abstract
Twenty-one nephrectomized patients with metastatic renal cell cancer were treated with recombinant interleukin 2 (rlL-2) and interferon alpha (rIFN alpha). rIL-2 was administered s.c. at a dose of 1 x 10(6) IU m(-2) every 12 h on days 1 and 2, followed by 0.5 x 10(6) IU twice daily on days 3-5; rIFN alpha-2 was given i.m. as 1.8 x 10(6) IU m(-2) on days 3 and 5 of each week for 4 consecutive weeks. The cycle was regularly repeated at 4-month intervals and continued ad libitum in patients showing some response and in patients with progressing disease. Of 20 patients evaluable for treatment response, one (5%) had a complete response and three (15%) showed partial response. Three patients (15%) achieved stable disease and 13 (65%) were evaluated as having progressive disease. The estimated actuarial 44-month survival rate was 44%. Toxicity was limited to WHO grades 1 and 2 only.
