Acute heart failure from a rapidly progressing large tumor in the right atrium

Abstract

The diagnosis and treatment of intracardiac mass are challenging for emergency physicians. Dyspnea is one of the most common chief complaints in ER among patients with rapidly progressed heart failure without significant medical history. Establishing such an unusual diagnosis based on dyspnea patients requires more evidence. We present a case of a patient who was diagnosed with a rapidly progressing right atrial mass.
