The previous guideline for the use of echocardiography was published in March 1997. Since that time, there have been significant advances in the technology of echocardiography and growth in its clinical use and in the scientific evidence leading to recommendations for its proper use.

Each section has been reviewed and updated in evidence tables, and where appropriate, changes have been made in recommendations. A new section on the use of intraoperative transesophageal echocardiography (TEE) is being added to update the guidelines published by the American Society of Anesthesiologists and the Society of Cardiovascular Anesthesiologists. There are extensive revisions, especially of the sections on ischemic heart disease; congestive heart failure, cardiomyopathy, and assessment of left ventricular (LV) function; and screening and echocardiography in the critically ill. There are new tables of evidence and extensive revisions in the ischemic heart disease evidence tables.

Because of space limitations, only those sections and evidence tables with new recommendations will be printed in this summary article. Where there are minimal changes in a recommendation grouping, such as a change from Class IIa to Class I, only that change will be printed, not the entire set of recommendations. Advances for which the clinical applications are still being investigated, such as the use of myocardial contrast agents and three-dimensional echocardiography, will not be discussed.

The original recommendations of the 1997 guideline are based on a Medline search of the English literature from 1990 to May 1995. The original search yielded more than 3000 references, which the committee reviewed. For this guideline update, literature searching was conducted in Medline, EMBASE, Best Evidence, and the Cochrane Library for English-language meta-analyses and systematic reviews from 1995 through September 2001. Further searching was conducted for new clinical trials on the following topics: echocardiography in adult congenital heart disease, echocardiography for evaluation of chest pain in the emergency department, and intraoperative echocardiography. The new searches yielded more than 1000 references that were reviewed by the writing committee.

This document includes recommendations for the use of echocardiography in both adult and pediatric patients. The pediatric guidelines also include recommendations for fetal echocardiography, an increasingly important field. The guidelines include recommendations for the use of echocardiography in both specific cardiovascular disorders and the evaluation of patients with frequently observed cardiovascular symptoms and signs, common presenting complaints, or findings of dyspnea, chest discomfort, and cardiac murmur. In this way, the guidelines will provide assistance to physicians regarding the use of echocardiographic techniques in the evaluation of such common clinical problems.

The recommendations concerning the use of echocardiography follow the indication classification system (eg, Class I, II, and III) used in other American College of Cardiology/American Heart Association (ACC/AHA) guidelines:

Class I: Conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective.
Class II: Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a procedure or treatment.
IIa: Weight of evidence/opinion is in favor of usefulness/efficacy.
IIb: Usefulness/efficacy is less well established by evidence/opinion.
Class III: Conditions for which there is evidence and/or general agreement that the procedure/treatment is not useful/effective and in some cases may be harmful.

Evaluation of the clinical utility of a diagnostic test such as echocardiography is far more difficult than assessment of the efficacy of a therapeutic intervention because the diagnostic test can never have the same direct impact on patient survival or recovery. Nevertheless, a series of hierarchical criteria are generally accepted as a scale by which to judge worth (1–3).

Hierarchical levels of echocardiography assessment.  

Because there are essentially no randomized trials assessing health outcomes for diagnostic tests, the committee has not ranked the available scientific evidence in an A, B, and C fashion (as in other ACC/AHA documents) but rather has compiled the evidence in tables. The evidence tables have been extensively revised and updated. All recommendations are thus based on either this evidence from observational studies or on the expert consensus of the committee.

The definition of echocardiography used in this document incorporates Doppler analysis, M-mode echocardiography, two-dimensional transthoracic echocardiography (TTE), and, when indicated, TEE. Intravascular ultrasound is not considered but is reviewed in the ACC/AHA Guidelines for Percutaneous Coronary Intervention (1) (available at http://www.acc.org/clinical/guidelines/percutaneous/dirIndex.htm) and the Clinical Expert Consensus Document on intravascular ultrasound (2) (available at http://www.acc.org/clinical/consensus/standards/standard12.htm). Echocardiography for evaluating the patient with cardiovascular disease for noncardiac surgery is considered in the ACC/AHA Guidelines for Perioperative Cardiovascular Evaluation for Noncardiac Surgery (3). The techniques of three-dimensional echocardiography are still in the developmental stages and are not considered here. New techniques that are still rapidly evolving and improvements that are purely technological in echo-Doppler instrumentation, such as color Doppler imaging and digital echocardiography, are not going to be separately discussed in the clinical recommendations addressed in this document. Tissue Doppler imaging, both pulsed and color, which detects low Doppler shift frequencies of high energy generated by the contracting myocardium and consequent wall motion, are proving very useful in evaluating systolic and diastolic myocardial function. However, these technological advances will also not be separately discussed in the clinical recommendations (4,5). Echocardiographic-contrast injections designed to assess myocardial perfusion to quantify myocardium at risk and perfusion beds also were not addressed.

These guidelines address recommendations about the frequency with which an echocardiographic study is repeated. If the frequency with which studies are repeated could be decreased without adversely affecting the quality of care, the economic savings realized would likely be significant. With a noninvasive diagnostic study and no known complications, the potential for repeating the study unnecessarily exists. It is easier to state when a repeat echocardiogram is not needed then when and how often it should be repeated, because no studies in the literature address this question. How often an echocardiogram should be done depends on the individual patient and must be left to the judgment of the physician until evidence-based data addressing this issue are available.

The ACC/AHA/ASE 2003 Guideline Update for the Clinical Application of Echocardiography includes several significant changes in the recommendations and in the supporting narrative portion. In this summary, we list the updated recommendations, as well as commentary on some of the changes. All new or revised language in recommendations appears in boldface type. Only the references supporting the new recommendations are included in this article. The reader is referred to the full-text version of the guidelines posted on the American College of Cardiology (www.acc.org), American Heart Association (www.americanheart.org), and American Society for Echocardiography (www.asecho.org) World Wide Web sites for a more detailed exposition of the rationale for these changes.

Recommendations for echocardiography to screen for the presence of cardiovascular disease.   Comment: A section has been added on the molecular genetics work that has identified a familial basis for many forms of cardiomyopathy, including dilated congestive cardiomyopathy, hypertrophic cardiomyopathy, and right ventricular (RV) dysplasia. A possible genetic basis for these cardiomyopathies supports echocardiographic screening of first-degree relatives (130–138).

Class I
5. First-degree relatives (parents, siblings, children) of patients with unexplained dilated cardiomyopathy in whom no etiology has been identified.

Class III

Recommendations for echocardiography in the adult patient with congenital heart disease.   Comment: A section has been added on the accuracy of echocardiography to allow surgery to proceed without catheterization in some congenital heart lesions. Echocardiography is useful in the performance of interventional therapeutic procedures (165–177).

Class I

  1. Patients with known congenital heart disease in whom it is important that pulmonary artery pressure be monitored (eg, patients with hemodynamically important, moderate, or large ventricular septal defects, atrial septal defects, single ventricle, or any of the above with an additional risk factor for pulmonary hypertension).
  2. Periodic echocardiography in patients with repaired (or palliated) congenital heart disease with the following: change in clinical condition or clinical suspicion of residual defects, obstruction of conduits and baffles, or LV or RV function that must be monitored, or when there is a possibility of hemodynamic progression or a history of pulmonary hypertension.
  3. Identification of site of origin and initial course of coronary arteries (TEE may be indicated in some patients).*

*TEE may be necessary to image both coronary origins in adults.

Recommendations for echocardiography in pediatric patients with arrhythmias/conduction disturbances.   Comment: Echocardiography is discretionary after radiofrequency catheter ablation. Persistent ventricular dilatation after successful ablation or effective medical control of the heart rate may indicate an arrhythmogenic primary cardiomyopathy (201–203).

Class IIa
2. Evidence of pre-excitation on ECG with symptoms.

Class IIb
3. Examination immediately after radiofrequency ablation.

Recommendations for echocardiography in pediatric acquired cardiovascular disease.   Comment: The leading cause of death after the first posttransplant year is transplant-related CAD. There is evidence that stress echocardiography identifies subclinical ischemia (204–213).

Class I

  1. Baseline and re-evaluation examinations of patients receiving cardiotoxic chemotherapeutic agents.
  2. Patients with severe renal disease and/or systemic hypertension.

Class III
1. Routine screening echocardiogram for participation in competitive sports in patients with normal cardiovascular examination.

Recommendations for echocardiography in pediatric acquired cardiopulmonary disease.   Comment: Echocardiography provides documentation of pulmonary artery hypertension and estimation of severity by the presence of RV dilation and/or hypertrophy, the presence of tricuspid or pulmonic valvular regurgitation, and Doppler estimation of RV systolic pressure (214,215).

Class I

  1. Re-evaluation after surgical intervention or initiation of oral and/or parenteral vasodilator therapy for pulmonary artery hypertension.
  2. Re-evaluation during withdrawal of extracorporeal cardiopulmonary support.

Recommendations for TEE in pediatric patients.   Comment: TEE has become particularly helpful in guiding placement of catheter-deployed devices used in closing atrial septal defects. It is essential in ensuring proper positioning of the device in the defect and assessing for residual shunts and abnormal device occlusion of venous inflow into the atria or encroachment on the atrioventricular valves. Likewise, placement of catheters for radiofrequency ablation of arrhythmogenic pathways can be facilitated by TEE when there are intracardiac abnormalities (216–222).

Class I

  1. Monitoring and guidance during cardiothoracic surgicalprocedures.
  2. Patients with right atrial to pulmonary artery Fontan connection, for identification of atrial thrombus.

Class IIa
1. Patients with lateral tunnel Fontan palliation.

Recommendations for intraoperative echocardiography.   Comment: This section is new. In 1996, a task force of the American Society of Anesthesiologists/Society of Cardiovascular Anesthesiologists (ASA/SCA) published practice guidelines for perioperative TEE. The guidelines were evidence based and focused on the effectiveness of perioperative TEE in improving clinical outcomes. A literature search conducted at that time retrieved 1844 articles, of which 588 were considered relevant to the perioperative setting. A more recent literature search identified an additional 118 articles related to the intraoperative use of echocardiography. The current text makes reference only to the latter. However, the indications for intraoperative echocardiography that are provided in these guidelines are based on both the initial ASA/SCA guidelines and the newer information (223–260).

For a detailed discussion of this topic, please see the full-text version of the guidelines posted on the ACC, AHA, and American Society of Echocardiography (ASE) World Wide Web sites.

Class I

  1. Evaluation of acute, persistent, and life-threatening hemodynamic disturbances in which ventricular function and its determinants are uncertain and have not responded to treatment.
  2. Surgical repair of valvular lesions, hypertrophic obstructive cardiomyopathy, and aortic dissection with possible aortic valve involvement.
  3. Evaluation of complex valve replacements requiring homografts or coronary reimplantation, such as the Ross procedure.
  4. Surgical repair of most congenital heart lesions that require cardiopulmonary bypass.
  5. Surgical intervention for endocarditis when preoperative testing was inadequate or extension to perivalvular tissue is suspected.
