Cardiac Imaging Report Content

From IHE Wiki
Jump to: navigation, search


This profile provides an HL7 CDA Implementation Guide for a Cardiac Imaging Report, derived from the Procedure Note specifications. The content is based on the roughly 100 Key Data Elements defined by the ACC/AHA Key Data Elements for Cardiac Imaging (JACC Vol. 53, No. 1, 2009).


Clinically-relevant cardiac imaging data is the key value proposition of this profile. The approach is to:

  1. reuse the distribution and structuring work from the XDS ( ITI domain), Medical summaries (PCC domain), and exchangable procedure notes (HL7)
  2. extend it through adding and codifying the Key Data Elements for Cardiac Imaging content identified by the American College of Cardiology (ACC) / American Heart Association (AHA) task-force on clinical data standards

Aligned with draft 2014 Meaningful Use requirements for care coordination


The Cardiac Imaging Report Content (CIRC) Profile specifies the content structure for a clinical report of a cardiology imaging exam, recorded in a DICOM Study. Such exams include:

  • Echocardiography (transthoracic - TTE, transesophageal - TEE, and TTE stress)
  • Cardiac computed tomography (angiography - CCTA, and coronary artery calcium scoring - CACS)
  • Cardiac magnetic resonance (angiography - MRA, and MR stress)
  • Cardiovascular nuclear medicine (SPECT myocardial perfusion, positron emission tomography - PET)
  • Diagnostic coronary catheter based fluoroscopy (interventional coronary angiography - ICA, and left ventriculography - LVG)

The CIRC Profile specifies the use of an HL7 Clinical Document Architecture (CDA) format for the report. Not included in the scope of this profile are non-imaging studies (e.g., ECG), electrophysiology procedures, and non-cardiology procedures (e.g., peripheral angiography). Such use cases may be supported by other similar content profiles.

Cardiac Imaging Report Content (CIRC) is a content profile – it is agnostic with respect to the workflow or data exchange mechanism in which the data is produced and handled.

The CIRC content is intended to be deployed, for example, in the Image Enabled Office (IEO) workflow profile for ambulatory care environments, the Displayable Reports (DRPT) workflow profile for in-patient environments, or the Cross-Enterprise Document Sharing (XDS) profile to propagate the content across organizational boundaries. It is important to note that that key report-generation/distribution workflow aspects such as physician identification, insurance preauthorization, report routing and acknowledgement, and patient consent, are out of scope for this Content Profile.

The aim is to enable collection and distribution of the most clinically-relevant discrete data on the diagnostic imaging procedures common in cardiology. The usage of the discrete data is two-fold:

  1. to enable individual test data to be more easily shared and used between care givers and systems
  2. to enable population-based outcomes-based research on test effectiveness

Systems Affected

The CIRC profile is a content profile, which defines the content of a Cardiac Imaging Report. The means of interchanging the report is not detailed in this profile but addressed in other profiles like IEO, DRPT, XDS or PDI. In general two types of systems would be relevant: A reporting workstation, Cardiovascular Information System or an Image Analysis workstation which creates a report and distributes it via one of the mechanism mentioned above. A workstation or system which is receiving and displaying the report. This could be an EMR System or any type of reporting workstation
