VENTRICULOATRIAL SHUNT DISTAL CATHETER PLACEMENT USING TRANSESOPHAGEAL ECHOCARDIOGRAPHY - TECHNICAL NOTE

Accurate placement of the distal end of a ventriculoatrial shunt at the cavo-atrial junction is important for long-term shunt function as well as for avoiding cardiac arrythmias, thrombus formation, and damage to myocardial tissue. Standard methods of intraoperative localization, including chest x-ray, pressure measurements, and electrocardiogram recording, can be inaccurate. By using intraoperative transesophageal echocardiography, the distal end of the catheter can be localized to the cavo-atrial junction.
