Visualization of right atrial tumor mass with transesophageal echocardiography through nasal way (TEENW)

Transesophageal Echocardiography Through Nasal Way as a Guide to Percutaneous Closure of Patent Foramen Ovale

“…Several studies reported the feasibility and accuracy of ICE using a miniaturized 10 Fr, monoplane, probe (AcuNav/Acuson/Siemens) to guide transcatheter PFO closure 13–15 . This miniaturized probe has been used previously during conventional TEE, 7 and the nasal approach by means of both the AcuNav catheter and a prototype TEE probe has also been utilized for the purpose 8–12 . Prompted by the above studies, we felt that the AcuNav transducer inserted via the nose could have been used profitably to guide transcatheter closure of PFO.…”

“…Three days later, the patient underwent percutaneous PFO closure with the Amplatzer septal occluder (AGA Medical, Golden Valley, Minnesota). Prompted by previous reports, 7–11 we decided to perform the procedure under guidance of TEENW, with the purpose to avoid either two vascular accesses or endotracheal intubation with further general anesthesia 12–15 …”

[12][13][14][15] With the patient in supine position, a miniaturized, 10 Fr, multifrequency (5.5-10 MHz), monoplane probe developed for intracardiac echocardiography (ICE) (AcuNav, Acuson/ Siemens, Mountain View, CA), was inserted into the esophagus, only with a lubricant jelly, through a nostril (Fig.…”
