title: Longitudinal angulation in coronary arteriography: apparatus and evaluation.
abstract: 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.
