    We here report a case of ST-elevation myocardial infarction (STEMI) due to simultaneous acute coronary artery occlusions of two major coronary arteries in a patient with coronary ectasia. The patient had been previously submitted to percutaneous coronary angioplasty with bare metal stent implantation in both culprit vessels. Very late stent thrombosis could be the cause of the first occlusion, triggering the event in the other vessel. In addition, concomitant embolic sources were not identified. Although routine aspiration thrombectomy in STEMI was not proven to be beneficial in randomized clinical trials, it was of great value in this case. We also discuss the relation between coronary ectasia, chronic inflammatory status, and increased platelet activity which may have caused plaque disruption in another already vulnerable vessel

    Objective As a parallel to the radial approach for left heart catheterisation, forearm veins may be considered for the performance of right heart catheterisation. However, data regarding the application of this technique under ultrasound guidance are scarce. The current study aims to demonstrate the feasibility of right heart catheterisation through ultrasound-guided antecubital venous approach in the highly heterogeneous population usually referred for right heart catheterisation. Methods Data from consecutive right heart catheterisations performed at an academic centre in Brazil, between January 2016 and March 2017 were prospectively collected. Results Among 152 performed right heart catheterisations, ultrasound-guided antecubital venous approach was attempted in 127 (84%) cases and it was made feasible in 92.1% of those. Yet, there was no immediate vascular complication with the antecubital venous approach in this prospective series. Conclusions Ultrasound-guided antecubital venous approach for the performance of right heart catheterisation was feasible in the vast majority of cases in our study, without occurrence of vascular complications

    A verminose é o principal fator limitante na produção de ovinos, seu controle tornou se cada vez mais difícil, devido a resistência dos helmintos gastrintestinais a alguns ingredientes ativos. Diante disso, o objetivo do trabalho foi analisar a eficiência da Moxidectina nocontrole das helmintoses em ovinos de uma propriedade rural de Concórdia SC. Realizou se o cálculo de teste de redução de contag em de ovos nas fezes (TRCOF) nos animais com alta carga parasitária (>900 OPG de ovos de Estrongilídeos) e pode se concluir que aMoxidectina apresentou baixa eficácia no rebanho avaliado
