Acute Left Bundle Branch Injury During Deep Septal Lead Implantation.

Left bundle branch pacing (LBBP) is a novel technique that has emerged as an alternative method for conduction system pacing. As a new modality, this procedure may carry complications that are yet to be explored. This report describes a case of injury to the left bundle branch during deep septal lead implantation for LBBP.

Nivolumab, a Double-Edged Sword: A Case Report of Nivolumab-Induced Myasthenia Gravis.

Nivolumab is a checkpoint inhibitor approved to treat various solid organs malignancies. Although checkpoint inhibitors are very efficacious, these medications are also associated with a variety of side effects that could be life-threatening. We present a case of nivolumab-induced myasthenia gravis in a patient with stage IV esophageal cancer, who was found to have generalized weakness, blurry vision, diplopia, and later developed acute hypoxic respiratory failure with subsequent intubation.

Pulmonary Embolism in COVID-19 and the Unanswered Questions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has ravaged the global society as we know it. As almost a dozen pharmaceutical agents go into randomized controlled clinical trials, multiple studies have surfaced trying to associate a hypercoagulable state to coronavirus disease 2019 (COVID-19) patients. We report two COVID-19 cases who presented with occlusive pulmonary embolism (PE) strongly supporting a hypercoagulable state incurred by SARS-CoV-2.
