Demonstrates an accessory enabling longitudinal angulation during coronary arteriography on standard tables, preserving video monitoring and radiation shielding.
When good visualization of the left coronary artery and proximal branches is difficult, the longitudinally angulated projection has proved useful. An accessory for achieving this angulation with a conventional angiographic table and without sacrificing the advantages of video monitoring and the protection of lead vinyl shielding is described.
