Angiocardiography has undergone tremendous development. It currently repre- sents the imaging system offering the highest resolution and greatest detail information. A widely applicable, complex technique able to meet high standards was required by the increasing number of coronary bypass interventions as well as by the advent of interventional catheter techniques, such as transluminal per- cutaneous catheter balloon dilatation, recanalization techniques, and intracoro- nary thrombolytic procedures. At the same time, improved image resolution began to furnish information on intracoronary flow...
