Objectives
Narrative objectives1
This study aimed to assess the ability to detect the right pericardiophrenic bundles using the venous as well as arterial phases of contrast-enhanced CT and to ascertain whether three-dimensional reconstruction of pericardiophrenic bundles from CT data could locate the running course of the PN detected by electrical phrenic pace map. Furthermore, we investigated what factors influence the detection of right pericardiophrenic bundles on contrast-enhanced CT.
