A cardiac arrest on a spiked helmet electrocardiographic sign in anterior leads in a patient with a diagnosis of acute myocardial infarction: A case report.

In patients with critical heart disease, such as acute coronary syndrome, aortic dissection, and other diseases, ST-segment elevation is a relatively common finding on the electrocardiogram (ECG). There are various other well-known signs described in heart diseases, such as negative T waves and q waves of necrosis. The "spiked helmet sign" is a novel electrocardiographic sign described first in 2011, whose pathophysiology and clinical applicability remain uncertain at this time. Herein we report the case of a cardiac arrest in a patient who developed the "spiked helmet electrocardiographic sign" concomitantly with acute myocardial infarction, leading to the patient's death from ventricular fibrillation. This case report aims to discuss the "spiked helmet electrocardiographic sign", and to detail the prognostic and diagnostic interest of this sign, wich seems to be different from a standard ST segment elevation.

Upper-extremity deep venous thrombosis and bilateral pulmonary embolism in a patient with COVID-19 under prophylactic anticoagulation: A case report.

The COVID-19 infection induces coagulation dysfunction resulting in an increased incidence of pulmonary embolism (PE) and deep venous thrombosis (DVT), mostly in the lower extremities. While upper-extremity DVT is less frequent than lower-extremity DVT, the thrombosis of internal jugular vein or brachiocephalic (innominate) vein is an uncommon presentation. All the current studies concerning the thrombotic risk linked to hospital COVID-19 indicate that therapeutic anticoagulation does not improve the clinical prognosis in the intensive care unit. Standard prophylactic anticoagulation is therefore recommended. But again, thrombotic complications of COVID-19 infection are still frequently reported nowadays despite anticoagulation therapy, as we can see in this case report. Here we report a rare case of a 50-year-old woman with a previous history of dyslipidemia, admitted for COVID-19 related acute respiratory failure. The patient developed during hospitalization an acute bilateral PE, with upper-extremity DVT including thrombosis of the left brachiocephalic vein extended to the left internal jugular vein, while under prophylactic anticoagulation since hospital admission, leading finally to the patient's death from respiratory failure. At present, the pathophysiology of the hypercoagulable state related to COVID-19 infection is poorly understood. The significant rate of thrombosis despite preventive and therapeutic dosage anticoagulation raises the possibility of a pathophysiology unique to COVID-19. This rare case highlights the importance of thrombotic morbidity and mortality associated with the SARS-CoV-2 epidemic, and the need for further studies to better understand the physiopathology behind the thrombotic state of COVID 19 infection and establish a more efficient way to deal with these complications.

Massive pulmonary embolism complicating mild Covid 19 pneumonia: Successful systemic thrombolysis using rt-PA in an elderly patient: A case report.

INTRODUCTION: and importance: Pulmonary embolism (PE) is still a major health concern around the world, and its link with SARS Cov-2 has led to an increase in morbidity, mortality, and ICU hospitalizations. CASE PRESENTATION: We present the case of a 92-year-old man with no prior medical history who admitted to our hospital in a state of acute respiratory failure, echocardiography revealed an acute right heart syndrome with a thrombus in the right atrium, computed tomography pulmonary angiogram revealed bilateral massive pulmonary embolism as well as Covid-19 pneumonia. He was treated with systemic thrombolysis using intravenous rt-PA (recombinant tissue plasminogen activator) with immediate clinical improvement and no hemorrhagic complications. CLINICAL DISCUSSION: In the presence of the SARs Cov-2 infection, several reports have indicated considerable procoagulant events, including life-threatening pulmonary embolism. There are still no current guidelines for the treatment of VTE in COVID-19 patients, but they are largely consistent with non-COVID-19 recommendations. Elderly patients are considered to be at high risk of developing thromboembolic complications, and also and above all are vulnerable to bleeding complications from anticoagulant treatments. CONCLUSION: This case highlight the importance of considering thromboembolic complications despite the severity of the associated SARS-cov-2 pneumonia and the role of prophylactic anticoagulation for Covid-19 patients hospitalized or not.

An uncommon presentation of COVID-19: concomitant acute pulmonary embolism, spontaneous tension pneumothorax, pneumomediastinum and subcutaneous emphysema (a case report).

The presenting symptoms and features of COVID-19 are non-specific and may be extrapulmonary complications such as thrombotic disorders but also pneumothorax, pneumomediastinum and subcutaneous emphysema; which are well-known complications of mechanical ventilation. Nevertheless, pneumothorax and/or pneumomediastinum, could complicate the course of a COVID-19 disease even in the absence of barotrauma involved. Herein, we report the case of a 55-year-old man with a previous history of erythroblastopenia due to thymoma admitted for COVID-19-related acute respiratory distress syndrome (ARDS) who simultaneously developed spontaneous tension pneumothorax, pneumomediastinum, subcutaneous emphysema and acute bilateral pulmonary embolism as presenting features of COVID-19 while on high-flow nasal cannula. This rare case highlights the importance of screening for other coexisting alternative diagnoses at the initial presentation of a patient suspected of COVID-19.
