Background: Over 6 million people in the US have a diagnosis of atrial fibrillation. Given the increased risk for stroke and systemic embolism, many patients are treated with direct oral anticoagulants (DOACs) to reduce their risk. In the major trials comparing to DOACs to warfarin for stroke and systemic embolism prevention in atrial fibrillation, DOACs [...]

Background: Warfarin and other anticoagulants increase the risk of hemorrhagic complications, including upper gastrointestinal hemorrhages (UGIB). Warfarin is commonly used in the management of atrial fibrillation to reduce the risk of ischemic stroke, and frequently resumed following UGIB. However, optimal timing of reinitiation remains unclear. Theory suggests that resuming warfarin immediately after UGIB would lead [...]

Case Presentation: A 53 year old female originally underwent an ablation for atrial fibrillation with post procedure course pericardial effusion requiring drain placement for 3 days. Patient recovered from original effusion and was sent home with colchicine and aspirin. She presented to our care on day 28 after procedure, one week after recent hospitalization. Patient [...]

Case Presentation: We report a case of a 38-year-old African American male with history of dysphagia who presented with complaint of acute chest pain. He described it as pressure like mid-sternal chest pain, radiating to his left arm associated with palpitations, worse on exertion and diaphoresis. On presentation, he was found to have atrial fibrillation [...]

Case Presentation: Introduction: Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. In the past decade, catheter ablation of AF has evolved from an investigational procedure to a frequent therapeutic one. Phrenic nerve injury (PNI) is a complication of ablation that internists should be familiar with, due to its increasing incidence. Case: A 77-year-old [...]
