The Simplified Extraction of Atrial Tumor With Targeted Loop Electricity (SEATTLE) Procedure.

The removal of intramyocardial masses has long been thought of as a surgical procedure and is generally reserved for patients with obstructive symptoms when the mass is thought to be benign. Thus, many patients who are incidentally diagnosed with intracardiac masses are either subjected to protracted follow-up with serial imaging awaiting tumor growth before surgical excision is ultimately offered. We report a novel procedure in which a 54-year-old man with an atrial myxoma underwent successful percutaneous resection using electrosurgery followed by removal with a novel endovascular retrieval system.

Feasibility of pulmonary valve imaging using transesophageal echocardiography upper esophageal view.

Background: The present study designed to evaluate feasibility of transesophageal echocardiographic (TEE) imaging of the pulmonary valve (PV) at the transaortic upper esophageal (TAUE) window. We hypothesized that patients with larger aorta would be more likely to have visualization of the PV from this TAUE window.

Methods: 2D TEE images of the PV were prospectively acquired by one operator at the TAUE window looking through the aortic arch.
