RESUMO

The impact of echocardiography on the continuum of cardiovascular health care is well established. Ongoing concerns regarding costs, accessibility, quality, and appropriateness of services rendered by practitioners of echocardiography have prompted various legislative proposals and regulatory policies from government, medical professional groups, and health plans. Specifically, there continues to be a drive to enact law for licensure of sonographers. These activities require continuing advocacy for the profession with active leadership. As part of its mission statement, the American Society of Echocardiography (ASE) states, "ASE strives to be a leader in public policy in order to create a favorable environment for excellence in the practice of echocardiography." As such, the ASE is committed to an increase in their interaction with legislators, payers, and policy makers. This article describes the historical perspective of state, federal, and provincial sonographer licensure issues to provide an understanding of the political perspectives.

RESUMO

In 1992, the American Society of Echocardiography published a report of the Sonographer Education and Training Committee's recommendations for education of sonographers who perform echocardiographic procedures. Since the publication of the original document, there has been continual progress in technology with the development of more sophisticated diagnostic applications that allow more information to be obtained from echocardiographic procedures. These recent changes in the clinical application of echocardiography should be included in all cardiac sonographer education programs. The American Society of Echocardiography, a professional society that currently represents approximately 2500 cardiac sonographers, provides these updated guidelines.

RESUMO

BACKGROUND: Clinical observations suggest that pulmonary artery occlusion pressure (PAOP) underestimates the resuscitative volumes required prior to release of aortic cross-clamp. METHODS: To investigate pressure-volume relationships associated with repair of abdominal aortic aneurysm (AAA), we simultaneously monitored PAOP by pulmonary artery catheter (PAC) and estimated left ventricular (LV) diastolic volume using two-dimensional transesophageal echocardiography (TEE) in 22 patients undergoing AAA repair. Data from PAC monitoring and TEE were collected before, during, and after aortic occlusion. TEE cross-sectional images were obtained at the mid-papillary level. RESULTS: Overall, PAOP correlated with left ventricular end-diastolic area (LVEDA), but the correlation was not particularly strong (r = 0.37, P < 0.0001). Even within individual patients, LVEDA varied widely for a given PAOP. The strength of the correlation between PAOP and LVEDA also appeared to deteriorate during the course of surgery. The best correlation was seen prior to aortic cross-clamping (r = 0.50, P < 0.0001), but fell somewhat during aortic cross-clamping (r = 0.41, P < 0.0001), and even further after unclamping (r = 0.25, P = 0.005). CONCLUSION: This study demonstrates a relatively weak correlation between PAOP and LVEDA using intraoperative TEE during AAA repair. Furthermore, the strength of the correlation worsened during surgery, particularly after unclamping. Although unclear at this time, this finding may be attributable to changes in LV compliance. We found TEE to be a valuable adjunct in guiding volume resuscitation of patients undergoing AAA repair.
