2. Methods
The indications included in this publication cover a variety of cardiovascular signs and symptoms as well as clinical judgments as to the likelihood of cardiovascular findings. Within each main disease category, a standardized approach was used to capture a significant number of clinical scenarios without making the list of indications excessive. The term “indication” is used interchangeably with “clinical scenario” in the document for brevity and does not imply that imaging should necessarily be done. Diagnostic catheterization may include several different procedure components. The indications developed focused primarily on 2 aspects of diagnostic catheterization. Many indications focused on the performance of coronary angiography for the detection of coronary artery disease (CAD), with other procedure components (eg, hemodynamic measurements, ventriculography) performed at the discretion of the operator. The majority of the remaining indications focused on hemodynamic measurements to evaluate valvular heart disease, pulmonary hypertension, cardiomyopathy, and other conditions, with the addition of coronary angiography at the discretion of the operator.
The spectrum of cardiovascular disease was addressed as it would apply to the standard adult catheterization laboratory. The writing group did not consider invasive evaluations of complex adult congenital heart disease in this document, with the belief that such complex cases would be best performed by individuals with considerable specialized expertise and at institutions with sufficient patient volume. Recommendations in this area are addressed in separate subspecialty publications. Additionally, invasive procedures such as endomyocardial biopsy, pericardiocentesis, or right heart catheterization not performed in the catheterization laboratory are not covered in this document.
The indications were constructed by a varied group of experts in both invasive and noninvasive diagnostic cardiac imaging. Subsequent modifications in the indications were made based on discussions with the task force and feedback from independent reviewers. Wherever possible, indications were mapped to relevant clinical guidelines and key publications/references (see Online Appendix available at
http://content.onlinejacc.org/j.jacc.2012.03.003/DC2).
A detailed description of the methods used for rating the selected clinical indications is found in a previous publication, “ACCF Proposed Method for Evaluating the Appropriateness of Cardiovascular Imaging.”

ACCF proposed method for evaluating the appropriateness of cardiovascular imaging.
Briefly, this process combines evidence-based medicine and practice experience by engaging a technical panel in a modified Delphi exercise. The technical panel first rated the indications independently, after which the results were summarized and the panel convened for a face-to-face meeting to discuss each indication. At this meeting, panel members were provided with their scores and a blinded summary of their peers’ scores. After the meeting, panel members once again independently rated each indication to determine the final scores.
Although panel members were not provided explicit cost information to help determine their ratings, they were asked to implicitly consider costs as an additional factor in their evaluation of appropriate use. In rating these criteria, the technical panel was asked to assess whether the use of the test for each indication is appropriate, uncertain, or inappropriate, and was provided with the following definition of appropriate use:
An appropriate diagnostic cardiac catheterization (left heart, right heart, ventriculography, and/or coronary angiography) is one in which the expected incremental information combined with clinical judgment exceeds the negative consequences by a sufficiently wide margin for a specific indication that the procedure is generally considered acceptable care and a reasonable approach for the indication.
Each member of the technical panel assigned a score to each indication, and the scores of the technical panel were tabulated for the final ratings and assigned an appropriateness rating as follows:
Median Score 7 to 9
Appropriate test for specific indication (test is generally acceptable and is a reasonable approach for the indication).
Median Score 4 to 6
Uncertain for specific indication (test may be generally acceptable and may be a reasonable approach for the indication). Uncertainty also implies that more research and/or patient information is needed to classify the indication definitively.
Median Score 1 to 3
Inappropriate test for that indication (test is not generally acceptable and is not a reasonable approach for the indication).
The division of these scores into 3 levels of appropriateness should be viewed as a continuum. It is important to emphasize that the category of “uncertain” is a distinct category and must not be considered either “appropriate” or “inappropriate” or lumped together with the other categories when characterizing appropriateness ratings. A rating of uncertain will exist if: (1) there is considerable diversity in the ratings among individual members of the technical panel indicating a wide range of opinions; (2) there is insufficient clinical information provided in the clinical scenario for the raters to reach a firm conclusion about appropriateness; or (3) there is a lack of specific information in the medical literature to make a firm recommendation regarding appropriateness. The uncertain category designation should encourage investigators to perform definitive research whenever possible. A designation of “uncertain” does not imply that the test should not be used in a specific clinical scenario. Many other factors known by the clinician and difficult to characterize within the structure of the AUC could affect a decision to perform or not perform a procedure in a specific patient. It is anticipated that the AUC reports will continue to be revised as further data are generated and information from the implementation of the criteria is accumulated. The writing group recognizes that a large portion of routine medical care would be rated as uncertain when held to the standards of the AUC and therefore hope this rating is correctly interpreted and can be placed in proper context.
To prevent bias in the scoring process, the technical panel was deliberately comprised of a minority of specialists in cardiac catheterization. Specialists, although offering important clinical and technical insights, might have a natural tendency to rate the indications within their specialty as more appropriate than nonspecialists. In addition, care was taken in providing objective, nonbiased information, including guidelines and key references, to the technical panel.

was analyzed based on the BIOMED rule for a panel of 14 to 16 members. As such, agreement is defined as an indication where 4 or fewer panelists’ ratings fell outside the 3-point region containing the median score.
Disagreement was defined as where at least 5 panelists’ ratings fell in both the appropriate and the inappropriate categories. Any indication having disagreement was categorized as uncertain regardless of the final median score.
10. Discussion
Diagnostic cardiac catheterization incorporates both imaging and hemodynamic procedures aimed at providing information to document specific cardiovascular disease states as well as help care for and improve the health of patients with known or suspected heart disease. The AUC are meant to provide guidance concerning the rational and timely use of diagnostic cardiac catheterization and coronary angiography. The current document provides an evaluation of many of the indications commonly considered in clinical practice. The writing group felt that review of the recommendations by general procedures and indications would be of the highest utility to clinical practice.
10.1 Assessment for CAD
Several sets of indications were rated regarding the use of invasive coronary angiography for the evaluation of CAD. The writing group felt that the decision to include left heart catheterization, left ventriculography, and perhaps other invasive procedures with coronary angiography should be at the discretion of the operator, depending on the clinical situation, the presence or absence of noninvasive assessments of LV function and pulmonary pressures, and the perceived accuracy of these noninvasive results.
In general, these indications were grouped by the clinical suspicion for acute coronary syndromes, suspected or known obstructive CAD, use of adjunctive invasive diagnostic technologies, evaluation of arrhythmias, and preoperative evaluation. Although these scenarios represented many common clinical indications for the evaluation of CAD, the writing group acknowledges that this is not comprehensive and thus there are likely clinical scenarios encountered in practice that are not rated in this document. Nevertheless, review of these scenarios should provide clinicians guidance on the use of coronary angiography.
Overall, patients with definite or suspected acute coronary syndromes were rated as appropriate for coronary angiography. These ratings reflect the current management and risk stratification of patients with acute coronary syndrome (ACS), which usually involves defining the presence, location, and degree of coronary stenosis and is based on abundant clinical studies on the management of ACS patients that used coronary angiography. Alternatively, in patients without known CAD, referral directly for coronary angiography for the suspicion of obstructive disease was felt to be appropriate only in symptomatic patients with a high pretest probability. The remaining patients (asymptomatic patients and symptomatic patients with low or intermediate pretest probability) were felt to be uncertain or inappropriate for a management strategy that used coronary angiography as the initial diagnostic test.
In patients with prior noninvasive testing, coronary angiography was rated inappropriate for asymptomatic patients with low-risk findings. Symptomatic patients with intermediate- or high-risk findings or equivocal/discordant noninvasive findings were rated appropriate for coronary angiography. Coronary calcium scores, regardless of severity, were rated as inappropriate indications for invasive coronary angiography in asymptomatic patients. The technical panel was not asked to rate calcium scores in symptomatic patients as this test is usually only performed in asymptomatic patients to assess risk. For patients with known CAD, asymptomatic patients following revascularization and medically managed patients with stable symptoms and low-risk noninvasive test findings were rated inappropriate in general for coronary angiography, whereas patients with high-risk noninvasive findings or those with limiting or worsening symptoms were rated as appropriate.
Several clinical scenarios related to the use of coronary angiography in the evaluation of certain cardiac arrhythmias were developed. Coronary angiography was rated as appropriate for patients resuscitated after cardiac arrest (assuming return of reasonable neurologic function) and for those with sustained VT regardless of symptoms. The other scenarios developed related to syncope, new onset atrial fibrillation/flutter, high-degree atrioventricular block, or new LBBB and were generally inappropriate for patients with a low coronary heart disease (CHD) risk and uncertain with a high CHD risk.
Scenarios for patients scheduled for noncardiac surgical procedures were also rated. In the preoperative setting for noncardiac surgery, direct catheterization and angiography was not generally considered appropriate unless the patient had significant risk factors or was undergoing transplantation of a solid organ or vascular surgery.
10.2 Assessment for Conditions Other Than CAD
Assessment of intracardiac and pulmonary pressures and other testing such as measurement of cardiac output were evaluated primarily in the setting of valvular heart disease, cardiomyopathies, and pulmonary hypertension. In the section on CAD assessment, the scenarios developed considered the use of coronary angiography and considered other procedures during the invasive evaluation (eg, left heart catheterization, left ventriculography) as secondary to the primary purpose of the evaluation and at the discretion of the operator. In a similar format, the scenarios developed in this section rated the use of the hemodynamic evaluations and considered coronary angiography as secondary to the primary purpose of the evaluation and at the discretion of the operator.
It should be noted that, in general, for patients with planned valvular surgery, preoperative catheterization for coronary anatomy was rated as appropriate. Additionally, in patients with symptomatic and severe valvular heart disease with discordant clinical and noninvasive imaging findings, hemodynamic assessment was rated as appropriate. Specific groups such as those with low transvalvular gradient, depressed LV function or decreased cardiac output were rated as appropriate for further evaluation using hemodynamic studies.
Patients without symptoms, with mild to moderate stenosis or concordant clinical and noninvasive findings were generally rated as inappropriate for diagnostic catheterization procedures with hemodynamic assessment. Those without symptoms but with severe disease were rated as uncertain. Asymptomatic patients with valvular heart disease were rated based on the noninvasive findings alone since discordance between a clinical impression and noninvasive findings in these patients would not be easily determined. Patients with pulmonary hypertension, either clinically suspected or documented and requiring evaluation for pharmacological therapy, were identified as appropriate for invasive hemodynamic assessment at rest as well as with provocative maneuvers (exercise or pharmacological challenge).
Specific groups such as those suspected of pericardial disease, intracardiac shunts, tamponade, suspected cardiomyopathy or patients who have received cardiac transplant were rated as appropriate for hemodynamic studies and endomyocardial biopsy.
10.3 Application of the Criteria
In their work developing and rating these clinical scenarios, the writing group and technical panel focused on the multiple goals of diagnostic cardiac catheterization and coronary angiography and common clinical scenarios seen in clinical practice. Clinical scenarios and ultimately the ratings of the technical panel were focused on obtaining information from the procedure that should help in the management of patients with suspected or known heart disease including providing needed reassurance about the clinical status of the patient. Additionally, the diagnostic catheterization AUC was written with recognition that these indications would be linked with the coronary revascularization AUC. In fact, the hope of the writing group was to develop a system that would inform patients and clinicians to increase the right patients undergoing appropriate invasive catheterization procedures before discussions and considerations around revascularization.
With these goals in mind, there are many potential applications for the AUC in this document. Decision support and educational tools should be developed. Ideally, these would translate these ratings into clinical tools used at the point of care to aid clinicians and patients in the decision to perform or undergo an invasive procedure.

Facilities and payers may choose to use these criteria, either prospectively in the design of protocols or review procedures, or retrospectively for quality reports. It is hoped that payers would use these criteria to ensure that their members receive necessary, beneficial, and cost-effective cardiovascular care, rather than for other purposes. It is expected that services performed for appropriate and/or uncertain indications will receive reimbursement. In contrast, services performed for inappropriate indications may require additional documentation to justify payment because of the unique circumstances or the clinical profile that may exist in such a patient. This additional documentation should not be required for uncertain indications. It is critical to emphasize that the writing group, technical panel, AUC Task Force, and clinical community do not believe an uncertain rating justifies denial of reimbursement for these invasive procedures. Rather, uncertain ratings are those in which the available data vary and many other factors exist that may affect the decision to perform or not perform cardiac catheterization and coronary angiography. The opinions of the technical panel often varied for these indications, reflecting that additional research is needed. Indications with high clinical volume that are rated as uncertain identify important areas for further research. The writing group and technical panel favor the collaborative interaction between patients, referring clinicians, and cardiologists in determining the need for these invasive procedures.
When evaluating physician or facility performance, AUC should be used in conjunction with efforts that lead to quality improvement. Prospective preauthorization procedures, if put in place, are most effective once a retrospective review has identified a pattern of potential inappropriate use. Because these criteria are based on current scientific evidence and the deliberations of the technical panel, they should be used prospectively to generate future discussions about reimbursement, but should not be applied retrospectively to cases completed before issuance of this report or documentation of centers/providers performing an unexpectedly high proportion of inappropriate cases as compared with their peers.
The writing group recognizes that these criteria will be evaluated during routine clinical care. To that end, specific data fields such as symptom status, presence or absence of acute coronary syndrome, history of CAD or revascularization, and type of noninvasive testing and findings will be required to determine individual appropriate use ratings. It is recognized that the characterization of symptoms is inherently subjective, and there is variability in the interpretation of many noninvasive tests. Fundamental to the application of the AUC is the understanding that the characterization of symptoms or interpretation of noninvasive tests is performed in a manner such that independent qualified reviewers would reach the same conclusions or support the conclusions of the individual physician about symptoms or noninvasive test results.
The primary objective of this report is to provide guidance regarding the use of diagnostic catheterization including coronary angiography, left heart catheterization and left ventriculography, and right heart catheterization for a diverse set of clinical scenarios. As with previous AUC documents, consensus among the raters was desirable, but an attempt to achieve complete agreement within this diverse panel would have been artificial and was not the goal of the process. Two rounds of ratings with substantial discussion among the technical panel members between the ratings did lead to some consensus among panelists. However, further attempts to drive consensus would have diluted true differences in opinion among panelists and, therefore, was not undertaken.
Future research analyzing patient outcomes for indications rated as appropriate and inappropriate will help ensure the equitable and efficient allocation of resources for cardiac catheterization. Further exploration of the indications rated as “uncertain” will help generate the information required to further define the appropriate use of cardiac catheterization procedures. Additionally, the criteria will need to be updated with the publication of ongoing trials in imaging and revascularization occurs.
In conclusion, this document represents the current understanding of the clinical utility of diagnostic cardiac catheterization. It is intended to provide a practical guide to clinicians and patients when these procedures.
