Canadian guidelines for training in adult perioperative transesophageal echocardiography. Recommendations of the Cardiovascular Section of the Canadian Anesthesiologists' Society and the Canadian Society of Echocardiography.

PURPOSE: To establish Canadian guidelines for training in adult perioperative transesophageal echocardiography (TEE). METHODS: Guidelines were established by the Canadian Perioperative Echocardiography Group with the support of the cardiovascular section of the Canadian Anesthesiologists' Society in conjunction with the Canadian Society of Echocardiography. Guidelines for training in echocardiography by the American Society of Echocardiography, the American College of Cardiology and the Society of Cardiovascular Anesthesiologists were reviewed, modified and expanded to produce the 2003 Quebec expert consensus for training in perioperative echocardiography. The Quebec expert consensus and the 2005 guidelines for the provision of echocardiography in Canada formed the basis of the Canadian training guidelines in adult perioperative TEE. RESULTS: Basic, advanced and director levels of expertise were identified. The total number of echocardiographic examinations to achieve each level of expertise remains unchanged from the 2002 American Society of Echocardiography and the Society of Cardiovascular Anesthesiologists guidelines. The increased proportion of examinations personally performed at basic and advanced levels, as well as the level of autonomy at the basic level suggested by the Quebec expert consensus are retained. These examinations may be performed in a perioperative setting and are not limited to intraoperative TEE. Training 'on-the-job', the role of the perioperative TEE examination, the requirements for maintenance of competence and the duration of training are also discussed for each level of training. The components of a TEE report and comprehensive TEE examination are also outlined. CONCLUSION: The Canadian guidelines for training in adult perioperative TEE reflect the unique Canadian practice profile in perioperative TEE and address the training requirements to obtain expertise in this field.

Economic impact of contrast stress echocardiography on the diagnosis and initial treatment of patients with suspected coronary artery disease.

OBJECTIVE: To estimate the impact of contrast stress echocardiography on resource use in the treatment of patients with suspected coronary artery disease (CAD). METHODS: Fifty-nine patients with suspected CAD underwent nuclear perfusion imaging and contrast echocardiography examination. Further treatment was planned after each test and a final treatment was recommended after reviewing the results of both examinations. Medical resources and productivity losses were then collected for a 3-month follow-up period. RESULTS: Diagnosis was possible in 96.6% of patients with nuclear perfusion imaging and 93.2% with contrast echocardiography, resulting in a cost per successful diagnosis of $637 (Can) and $476 (Can), respectively. For the majority of patients (74%), both tests provided the same result, but for 12 patients nuclear imaging suggested abnormal perfusion, whereas contrast echocardiography indicated normal function and for 2 patients it was the opposite situation. Per-patient costs for the total patient population decreased from $316 (Can) after nuclear perfusion imaging to $250 (Can) when results from both tests were known. Three-month follow-up societal costs were $441 (Can) per patient, with hospitalization contributing 58% of this total cost. CONCLUSION: Contrast echocardiography has a similar success rate to nuclear perfusion imaging in diagnosing CAD, but has a 28% lower cost and has the potential of additional cost savings through the elimination of further diagnostic tests.
