About

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).

Full 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.

Enrollment: 42 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Ability of the patient or proxy to read, comprehend, and sign informed consent document.

Exclusion criteria

• Presence of esophageal disorders that may complicate transesophageal echocardiography (strictures, varices, fistula, prior esophageal surgery)
• Presence of coagulopathy or other bleeding diathesis
• Inability to tolerate brief periods of apnea
• Presence of pulmonary vascular disease
