sue for examination, was conducted in the two human patients, also showing no arrhythmia or other complications.

"Our studies suggest that using a trans-esophageal process to gain access to the heart may be feasible and safe for patients as an alternative to the much longer, indirect route through the femoralis artery in the groin or to open surgery," said Annette Fritscher-Ravens, M.D., of the Homerton University Hospital and lead study author. "This may be of specific interest for patients who have damaged heart muscle after a heart attack and may benefit from the injection of therapies directly into the muscle without another operation."

Endoscopic Ultrasound (EUS)-Guided Angiography: A Novel Approach to Diagnostic and Therapeutic Intervention in the Vascular System [Abstract W1321]

The human vascular system represents a unique highway that allows access to every part of the body, and problems with the system can result in serious health conditions. The ability to safely intervene, diagnose, and treat vascular abnormalities with minimally-invasive techniques represents significant advances in the practice of medicine.

In this study, researchers review the technical challenges and potential value of an endoscopic ultrasound (EUS)-guided angiography. Endoscopic ultrasonography is the practice of using an ultrasound transducer at the tip of an endoscope to visualize and offer therapeutic intervention to the gastrointestinal tract and its surrounding structures, which includes nearby vasculature and organs.

The researchers tested the feasibility of EUS to perform angiography in three pigs. EUS was conducted on each pig to identify major blood vessels, including the thoracic and abdominal aorta, celiac axis, superior mesenteric artery, splenic vein, portal vein, splenic artery and hepatic veins. During the EUS, the researchers injected contrast to improve vascular visualization, and - performed angiography using
