A Case of Severe Left Atrial Compression by a Mid-Esophageal Metastatic Mass

Left atrial (LA) compression by an esophageal mass is a rare structural finding and may lead to life-threatening manifestations. Often, LA compression is the result of the neighboring organs of the heart. Extracardiac etiologies of LA compressions are usually incidentally noted and better characterized with multiple imaging techniques. We present a case of a middle-aged man evaluated for sinus tachycardia, who was found to have severe LA compression secondary to an esophageal mass. This patient’s pathology was uniquely depicted in multiple imaging modalities.
