          Abstract

          Background: Cardiac magnetic resonance tomography (CMR) is a new imaging technique capable of imaging the aortic valve with high resolution. We assessed the aortic valve area (AVA) in patients with aortic stenosis (AS) using CMR and compared the results to those obtained by transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE). Methods: Forty-two patients (36% female, 71 ± 8 years) symptomatic for AS underwent TTE followed by TEE to determine the AVA; the continuity equation was used with TTE and the planimetry technique with TEE. In 26 of these patients, the AVA was additionally obtained by CMR planimetry. Results: The mean AVA derived by TTE, TEE and CMR were 0.74 ± 0.27, 0.87 ± 25 and 0.97 ± 0.30 cm<sup>2</sup>, respectively. The mean absolute differences in AVA were 0.13 ± 0.19 cm<sup>2</sup> for TTE vs. TEE, 0.21 ± 0.25 cm<sup>2</sup> for TTE vs. CMR and 0.05 ± 0.11 cm<sup>2</sup> for CMR vs. TEE. Conclusion: There is a good agreement between CMR and the echocardiographic determination of the AVA. If multicenter, large-scale studies confirm these observations, CMR could serve as a noninvasive alternative to TTE/TEE for the assessment of AVA in AS.

            The safety of intraoperative transesophageal echocardiography: a case series of 7200 cardiac surgical patients.

            Stanton Shernan, I Kallmeyer, S. Body … (2001)
            Transesophageal echocardiography (TEE) is an invaluable intraoperative diagnostic monitor that is considered to be relatively safe and noninvasive. Insertion and manipulation of the TEE probe, however, may cause oropharyngeal, esophageal, or gastric trauma. We report the incidence of intraoperative TEE-associated complications in a single-center series of 7200 adult cardiac surgical patients. Information related to intraoperative TEE-associated complications was obtained retrospectively from the intraoperative TEE data form, routine postoperative visits, and cardiac surgical morbidity and mortality data. The overall incidences of TEE-associated morbidity and mortality in the study population were 0.2% and 0%, respectively. The most common TEE-associated complication was severe odynophagia, which occurred in 0.1% of the study population. Other complications included dental injury (0.03%), endotracheal tube malpositioning (0.03%), upper gastrointestinal hemorrhage (0.03%), and esophageal perforation (0.01%). TEE probe insertion was unsuccessful or contraindicated in 0.18% and 0.5% of the study population, respectively. These data suggest that intraoperative TEE is a relatively safe diagnostic monitor for the management of cardiac surgical patients. The overall morbidity (0.2%) and mortality (0%) rates of intraoperative transesophageal echocardiography (TEE) were determined in a retrospective case series of 7200 adult, anesthetized cardiac surgical patients. The most common source of TEE-associated morbidity was odynophagia (0.1%), which resolved with conservative management. These results suggest that TEE is a safe diagnostic tool for the management of cardiac surgical patients.
