Gas Embolism With Use of Argon Plasma Coagulation
Completed
- Conditions
- Embolism, Air
- Registration Number
- NCT00676858
- Lead Sponsor
- Beth Israel Deaconess Medical Center
- 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).
- 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.
Recruitment & Eligibility

- All
- Target Recruitment
- 42
Inclusion Criteria
- Adults (male and female) 18 years of age or older

- 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
