RESUMEN
AIM: Takotsubo cardiomyopathy is a cardiac syndrome characterized by reversible left ventricular dysfunction, ischemic changes on electrocardiogram, elevation of cardiac biomarkers, absence of obstructive coronary artery disease in the setting of various stressing conditions. To date, little is known on best clinical management of this syndrome in coronary care units. Whe thus aimed to present our experience in a real life takotsubo population. METHODS: We identified all patients with Takotsubo cardiomyopathy at our center Maria Vittoria Hospital, Turin, between October 2006 and February 2012. Patients where considered to have Takotsubo syndrome if they presented chest pain on admission, new elettrocardiographic changes suggestive of myocardial ischemia, evidence of apical balloning with hyperkinesis of basal segments on echocardiography, rise in troponin I and, after coronary angiography, no coronary artery disease. We adjudicated the following clinical events: death and recurrence of ischemic events; we also made a detailed analysis of the stressing conditions leading to clinical syndrome. RESULTS: A total of 26 patients were included, 4 (15%) males and 22 (85%) females; mean age was 71±13. After more than 1 year median follow-up the incidence of death was 7.7% (2 deaths), with all deaths, due to cardiogenic shock, occurring in the first 10 days of hospitalization; 2 patients (8%) experienced recurrence of ischemic event. Leading cause of Takostubo was major depressive episode (16%), followed by mourning (12%), falling down with difficulties in standing up (12%), vomiting (8%) and pulmonary infection (8%). In the coronary care unit major complications of patients with Takotsubo syndrome were acute hearth failure (62%), cardiogenic shock (27%), sepsis (31%), pulmonary aedema (27%) and anemia (12%). Two patients needed non-invasive ventilation support and one intra-aortic balloon conterpulasation. In addition one patient developed rabdomyolysis and one left heart thrombus. Cornerstone drug therapy was as follows: 96% of patients took aspirin, 58% beta blockers, 54% nitroglicerine, 46% intravenous heparin, 27% dopamine. CONCLUSION: Takotsubo syndrome is an important safety issue occurring predominantly in post-menopausal women undergoing specific stressing condition. Heart failure and cardiogenic shock are the most serious clinical complication and leading cause of death in the short period, good prognosis is seen thereafter.

We report the first related case of a metastasis from melanoma appeared on a pacemaker device pocket. The stadiation exams showed that this is the only localization of the pathology. The integrated management from both cardiologic and dermatologic surgery was described. It was composed by two interventions, a first time for the implant of a new device contralaterally, and later by the surgical intervention, with exeresis of the lesion, radical lymph node dissection of the axilla and plastic reconstruction. The previous pacemaker implant may hypothetically create a favourable environment for metastatic cells ingrowth. This could be explained by a chronic inflammatory reaction and capsule formation around the device as previously reported, or by a blockage of lymphatic drainage in this specific site.

AIM: Stent thrombosis is a major safety issue after percutaneous coronary intervention (PCI) with stent implantation and it is associated with major early and mid-term complications. However, its long-term impact has been incompletely described. We thus aimed to appraise incidence, predictors and very long-term outlook of stent thrombosis after bare metal stent (BMS) or drug-eluting stent (DES) implantation. METHODS: We identified all patients undergoing PCI with BMS or DES at our center between July 2002 and June 2004. For the purpose of this study, we employed a composite definition of stent thrombosis including any Academic Research Consortium stent thromboses (definite, probable, or possible). We adjudicated the following clinical events: death, myocardial infarction (stent thrombosis related), repeated revascularization, and the composite of these events (i.e., major adverse cardiac events, MACE). RESULTS: A total of 1112 patients were included, 854 (76.8%) treated with BMS and 258 (23.2%) treated with DES. At a median follow-up of 61.2 (11.03) months the incidence of stent thrombosis was 20 (1.8%), with 14 (1.3%) definite, 4 (0.4%) probable, and 2 (0.1%) possible according to the American Research Consortium statement. Patients developing stent thrombosis were more likely to have more complex angiographic features at baseline (including angiographically evident thrombus, 4 [20%] vs. 73 [6.6%], P=0.02) and a saphenous vein graft as target vessel (2 [10%] vs. 28 [2.5%], P=0.04). Conversely, being treated with a BMS or a DES did not confer any significant decrease or increase in the risk of stent thrombosis, as 7 [35%] of those with stent thrombosis had received at least a DES vs. 251 [22.9%] of those without stent thrombosis, P=0.28). Early clinical outcomes (at 30 days) distinguishing those with stent thrombosis versus those without were as follows: death in four (20%) vs. 2 (0.2%, P<0.001), myocardial infarction in 1 (5%) vs. 7 (0.6%, P=0.02), revascularization in 5 (25%) vs. 43 (3.9%, P<0.001), and MACE in 8 (40%) vs. 53 (4.8%, P<0.001). After more than 60 months of clinical follow-up, outcomes were as follows: death in 7 (35%) vs. 147 (13.5%, P=0.057), myocardial infarction in 6 (30%) vs. 40 (3.6%, P<0.001), revascularization in 15 (75%) vs. 317 (29%, P<0.001), and MACE in 19 (95%) vs. 453 (41.5%, P<0.001). CONCLUSION: This long-term registry shows that stent thrombosis remains a major safety issue after PCI with stent implantation, with a significant prognostic impact. However, in the present work the risk of stent thrombosis was similar with either DES or BMS, suggesting thus that DES are not associated with any increase in long-term thrombotic risk in comparison to BMS.

AIM: Peripheral arterial disease (PAD) in patients undergoing percutaneous coronary intervention (PCI) with stent implantation is a well known risk factor leading to an increased rates of stroke, cardiovascular death and myocardial infarction. Anyway there are few data on very-long term outcome (more than 1 year follow up) of PAD after stent implantation. We thus aimed to evaluate the influence of PAD on very long-term outcome of our PCI-population. METHODS: We retrospectively identified all patients undergoing PCI with stent implantation at our center between July 2002 and June 2004, and thus eligible for at least 4 years of follow-up. For the purpose of this study, we considered a diagnosis of PAD based on clinical evaluation and/or angiographic documentation. We adjudicated the following clinical events: death, myocardial infarction, repeat revascularization, and their composite (i.e. major adverse cardiac events, MACE). RESULTS; A total of 1008 patients were included, 109 with PAD and 899 Without PAD. Those with had more often diabetes (35% vs. 25%, P=0.002), hypertension (83% vs. 68%, P=0.001) and unfavorable basal clinical condition at the start of this study: past-Percutaneous Coronary Intervention (PCI) (30% vs. 22%, P=0.005), past-Coronary Artery Bypass Graft (CABG) (24% vs. 14%, P=0.001), ejection fraction (EF) <35% (14% vs. 7%, P=0.02) and chronic renal failure (CRF) (15% vs. 6%, P=0.002). In addiction patient with PAD were more likely to have chronic total occlusion (CTO) (36% vs. 25%, p=0.02) and unprotected left main (16% vs. 8%,P=0.01). Clinical outcome at the time of follow-up (4,42 ± 1,66 years) was as follow: Revascularization (53% vs. 37%, P=0.002), Cardiac death (21% vs. 13%, P=0.04), MACE (69% vs. 49%, p<.001). Independent predictors of MACE according to our survival analysis were: PAD (HR 1.31; 95% CI 1.01-1.69), Age >75 (HR 1.23; 95% CI 1-1.51), Chronic heart failure (HR1.72; 95% CI 1.19-2.5), Unprotected left main (HR 1.48; 95% CI 1.12-1.96). CONCLUSION: This long-term registry shows that PAD remains an important clinical condition that negatively influences the outcome of patients undergoing PCI with stent implantation in a very long-term follow-up period.

AIM: Patients with prior coronary artery bypass grafting (CABG) represent a sizable portion of those undergoing percutaneous coronary intervention (PCI): in many instances, it is unclear whether performing PCI on the bypass graft or in the native coronary vessels can offer the best risk-benefit balance. METHODS: We included patients with prior CABG undergoing PCI at our center between July 2002 and June 2004 and we distinguished them in three groups. Those in whom PCI was performed on stenotic saphenous vein graft (SVG group), those in whom PCI was performed on native vessels despite the presence of potentially treatable SVG disease (optional native group), and those in whom PCI had to be performed mandatorily in the native vessels because of chronic SVG occlusions or disease in non-bypassed segments (mandatory native group). The primary end-point was long-term rate of major adverse clinical events (MACE, i.e. death, myocardial infarction, or target vessel revascularization). RESULTS: We identified 109 patients: 28 were in the SVG group, 25 in the optional native group, and 56 in the mandatory native group. Early major adverse cardiac events (MACE) occurred with similar frequency in the three groups (respectively, 9.1%, 0% and 5.7%, P=0.35). After more than three years of follow-up, MACE occurred in 39.3% vs. 28 and 39.4% (P=0.59), death occurred in 27.2 vs. 24.0% vs. 13.5% (P=0.30), and TVR in 27.3% vs. 8.0% vs. 28.8% (P=0.14). CONCLUSION: In selected patients, PCI of native coronary vessels despite the presence of apparently treatable SVG lesions can be envisioned.
