[Usefulness of an audiovisual support to informed consent before percutaneous coronary intervention procedures].

Background: Informed consent must be obtained from all patients undergoing medical procedures, especially when these imply a significant risk of severe adverse events. However, as for interventional cardiology, recall of information has been shown to be poor. In this study we evaluated the usefulness of an audiovisual support, in adjunct to the standard written informative form, in obtaining: (a) effective patient information before invasive coronary procedures, and (b) patient familiarization with the cath lab team, equipment, and the main procedural phases.
