Transesophageal 3-dimensional echocardiographic guidance for pacemaker lead placement improves lead position accuracy and reduces fluoroscopy
Authors' conclusion
For pacemaker and ICD lead placement, 3DE guidance substantially improves the accuracy of lead placement in the septum, with a shorter QRS duration, while reducing fluoroscopy exposure.
