Study Description
Brief Summary:
The purpose of this study is to use transesophageal echocardiography (TEE) to determine the incidence, severity, and clinical significance of gas bubbles during argon plasma coagulation (APC).

Condition or disease
Embolism, Air

Detailed Description:
Gas embolism is a rare but serious complication of APC. We will use TEE to monitor for gas bubbles during APC. APC will be terminated if gas bubbles are associated with ischemic heart rhythms, wall motion abnormalities, or if large gas bubbles are noted in the left ventricle.
