Optimal use of left ventriculography at the time of cardiac catheterization: a consensus statement from the Society for Cardiovascular Angiography and Interventions.

The rationale to perform left ventriculography at the time of cardiac catheterization has been little studied. The technique and frequency of use of left ventriculography vary by geographic regions, institutions, and individuals. Despite the recent publication of guidelines and appropriate use criteria for coronary angiography, revascularization, and noninvasive imaging, to date there have been no specific guidelines on the performance of left ventriculography. When left ventriculography is performed, proper technique must be used to generate high quality data which can direct patient management. The decision to perform left ventriculography in place of, or in addition to, other forms of ventricular assessment should be made taking into account the clinical context and the type of information each study provides. This paper attempts to show the role of left ventriculography at the time of coronary angiography or left heart catheterization. The recommendations in this document are not formal guidelines but are based on the consensus of this writing group. These recommendations should be tested through clinical research studies. Until such studies are performed, the writing group believes that adoption of these recommendations will lead to a more standardized application of ventriculography and improve the quality of care provided to cardiac patients.
