Right Ventricular Perforation Leading to Sudden Death Due to Extracorporeal Membrane Oxygenation (ECMO) Canula Dislodgement.

ECMO has been playing an increasingly important role in the management of coronavirus disease (COVID-19)-related acute respiratory distress syndrome (ARDS). However, despite its potential benefits, high mortality rates are still being reported worldwide. Herein, we report the case of a 32-year-old male who presented with worsening shortness of breath secondary to COVID-19. Unfortunately, he experienced a sentinel event when the cannula became dislodged due to coughing, which led to a right ventricular perforation and sudden pulseless electrical activity (PEA) cardiac arrest.

Esophageal Schwannoma: An Important Differential Diagnosis for Esophageal Subepithelial Lesions.

Esophageal schwannoma is a rare tumor and is classified as one of the esophageal subepithelial lesions (SELs). Endoscopic ultrasound (EUS) evaluation is the gold standard for evaluating subepithelial lesions. Differentiation through EUS-guided fine needle aspiration is sometimes important to exclude lesions with malignant potential. Immunohistochemistry differentiates schwannoma from other subepithelial lesions. Strong and diffuse positivity for S100 is characteristic. The decision for conservative management versus endoscopic or thoracoscopic intervention is made based on the tumor size, location, and symptoms.
