RESUMO
Antiplatelet therapy is mandatory for prevention of thrombotic events in patients with a recent history of acute coronary syndromes and/or percutaneous coronary interventions. However, if an urgent surgery is required during antiplatelet therapy, a compromise between the ischemic/thrombotic and hemorrhagic risk has to be reached. Different bridging schemes are reported in the literature, but there is no clear consensus on the optimal treatment strategy in terms of efficacy and safety. Although some indications about the perioperative management of antiplatelet therapy regarding specific surgical specializations are available, balancing the thrombotic and hemorrhagic risk on an individual basis, no evidence referring to neurosurgical or neuro-oncologic procedures is reported. Herein, we present our preliminary experience in the perioperative management of a patient who underwent a neurosurgical procedure for the resection of a primary malignant brain tumor using an intravenous P2Y12 inhibitor (cangrelor) as bridging therapy after a recent acute myocardial infarction treated with primary percutaneous coronary intervention and stenting. The oral P2Y12 inhibitor (clopidogrel) was withdrawn 5 days prior to the surgical procedure and continuous infusion of cangrelor was started 3 days before the surgery at a dose of 0.75 µg/kg/min. Cangrelor was discontinued 2 hours before surgery and resumed 72 hours after tumor resection for further 60 hours. Neither cangrelor-related bleeding nor cardiac ischemic events were observed in the perioperative period and the following 90 days, supporting data regarding the feasibility and safety of this bridging scheme. Further studies are needed to confirm our promising results.
RESUMO
PURPOSE: Abdominal aortic aneurysms (AAA) are observed in 6% of patients with concomitant aortic valve stenosis (AS) requiring aortic valve replacement. Optimal management of these concomitant pathologies is still debated. CASE REPORT: An 80-year-old man presented with acute heart failure due to a severe AS. Past medical history included AAA under regular surveillance. A thoracic and abdominal computed tomography angiography (CTA) confirmed a 6 mm increase of AAA over an 8-month period (max 55 mm). A multidisciplinary team prescribed a simultaneous endovascular approach of transcatheter aortic valve implantation (TAVI) followed by endovascular aneurysm repair (EVAR) under local anaesthesia with bilateral femoral percutaneous access. No intra or post-procedural complications were registered; technical success was confirmed by completion angiography and post-operative ultrasound. The patient was discharged on postoperative day 5. A 2-month post-operative CTA confirmed ongoing technical success. CONCLUSION: Combined TAVI and EVAR under local anaesthesia for AS and AAA was associated with reduced hospital stay and technical success at 2 months from intervention in this case report.

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 54â±â11âyears and the majority were women (n = 50, 86%) with one or fewer cardiovascular risk factors (nâ=â35, 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 (nâ=â51, 88%) were treated conservatively without revascularization. The in-hospital and 30-day clinical course was uneventful in most patients (nâ=â54, 93%) with two cardiac deaths. During a median follow-up of 12âmonths, there were no further deaths. The global rate of SCAD recurrence was significant (nâ=â8, 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.

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.

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.
