Abstract
Transesophageal echocardiography is a semi-invasive technique that allows an evaluation of cardiac morphology and function in real time and it is a quality standard in cardiovascular surgery. It has become a fundamental tool for both monitoring and diagnosis in the intraoperative period that allows decide the correct surgical planning and pharmacological management. The goal of this document is to answer the questions of when and how the perioperative TEE should be performed in cardiovascular surgery, what are their applications in the intraoperative, who should perform it and how the information should be transmitted. The authors made a systematic review of international guidelines, review articles and clinical trials to answer by consensus to these questions.

Abstract
Peri-operative echocardiography is widely used because it provides information that significantly influences clinical/surgical management and improves outcome in patients undergoing cardiac surgery. The role of intra-operative trans-esophageal echocardiography (TEE) in valvular heart disease cannot be emphasized enough. Increasing use of newer surgical techniques-valve repairs and minimal invasive cardiac surgery also warrants intra-operative TEE. It gives us better insight into the anatomy and physiology of the valvular lesion by digital imaging. This manuscript provides an illustrative case based overview of intra operative TEE (IOTEE) in heart valve surgery.

Abstract
Intraoperative (IO) transesophageal echocardiography (TEE) is widely used for assessing the results of valvular heart disease (VHD) surgery. Epiaortic ultrasonography (EAU) has been recommended for prevention of perioperative strokes. To what extent does high-quality evidence justify the widespread use of these imaging modalities? In March 2009, we searched MEDLINE (PubMed and OVID interfaces) and EMBASE for studies published in English using database-specific controlled vocabulary describing the concepts of IOTEE, cardiac surgery, VHD, and EAU. We found no randomized trials or studies with control groups assessing the impact of IOTEE in VHD surgery. Pooled analysis of 8 observational studies including 15,540 patients showed an average incidence of 11% for prebypass surgical changes and 4% for second pump runs, suggesting that patients undergoing VHD surgery may benefit significantly from IOTEE, particularly from postcardiopulmonary bypass IOTEE in aortic repair and mitral repair and replacement, but less so in isolated aortic replacement. Further available indirect evidence was satisfactory in the test accuracy and surgical quality control aspects, with low complication rates for IOTEE. The data supporting EAU included 12,687 patients in 2 prospective randomized studies and 4 nonrandomized, controlled studies, producing inconsistent outcome-related results. Despite low-quality scientific evidence supporting IOTEE in VHD surgery, we conclude that indirect evidence supporting its use is satisfactory and suggests that IOTEE may offer considerable benefit in valvular repairs and mitral replacements. The value of IOTEE in isolated aortic valve replacement remains less clear. Evidence supporting EAU is scientifically more robust but conflicting. These findings have important clinical policy and research implications.

Abstract
BACKGROUND Previous studies have shown that intraoperative transesophageal echocardiography provides important preoperative and postoperative information in various cardiac and noncardiac surgeries that may alter patient management and outcome. The role of intraoperative transesophageal echocardiography in patients in whom isolated coronary artery bypass graft surgery is anticipated has been reported only in small selected groups. This study was designed to prospectively evaluate the role of intraoperative transesophageal echocardiography in a large, nonselected group of patients undergoing primarily coronary artery bypass graft surgery. METHODS From January 2001 to December 2003, 474 consecutive patients (76% men, 24% women) aged 30 to 89 years (mean age of 70 +/- 10 years) who were undergoing coronary artery bypass graft surgery had prebypass and postbypass intraoperative transesophageal echocardiography. New findings and alterations in the surgical plan were documented prospectively. RESULTS New prebypass findings were found in 10% of patients, and the surgical plan was altered in 3.4% of patients. New postbypass findings were found in 3.2% of patients, altering the surgical plan in 2% of patients. CONCLUSIONS This large consecutive, nonselected, prospective study reveals the significant impact of intraoperative transesophageal echocardiography in patients having coronary artery bypass graft surgery as a primary procedure. New findings (prebypass and postbypass) were found in 13% of patients overall, and the surgical plan was altered in 5.5% of patients. This study supports the use of intraoperative transesophageal echocardiography in patients undergoing primarily coronary artery bypass graft surgery.

Abstract
No single monitoring tool in the last decade has had more of an effect on intraoperative decision making and surgical management of cardiac valvular pathologies than has TEE. It has become the standard of care for evaluating reparative valvular procedures, thus providing an immediate gauge of the surgical results and helping to avoid suboptimal surgical outcomes. As the technology of TEE and its application advance, so too should the ability to diagnose and manage valvular pathologies, broaden the range of surgical options, and ultimately improve patient outcomes.

Abstract
OBJECTIVE Transesophageal echocardiographic examination tends to be somewhat observer and experience dependent, and observer bias can arise easily when data are calculated and interpreted by unskilled, nonblinded, or single observers. The study plan was to see whether authors have adequately described how observer bias is minimized in their studies. Thus, a study was conducted systematically reviewing methods reported in transesophageal echocardio graphy articles in peer-reviewed anesthesiology journals versus those reported in peer-reviewed cardiology journals. INTERVENTIONS After MEDLINE searches of the literature published from 1997 through 1999, the authors investigated 56 anesthesiology reports and 56 randomly selected, year-matched cardiology reports. An 8-item questionnaire was developed that examined several factors: the number of observers and their experience levels, whether observers were blind to clinical data, whether low-quality images were excluded, the use of on-line or off-line analysis, and observer variability. MAIN RESULTS The analysis revealed inadequacies in reporting of important information that relates to bias and quality in 91.1% of anesthesiology and 98.2% of cardiology articles. Observer variability was not reported in 50.0% of the anesthesiology reports and 67.9% of the cardiology reports; however, difference between the 2 bodies of literature was not significant. The journal impact factor was significantly higher for the cardiology literature than for the anesthesiology literature (2.42 [0.386-10.893] v 1.07 [0.664-3.439]; median [range], p < 0.001). CONCLUSION Articles reviewed had at least some inadequacies in reporting the methods to minimize observer bias in both the anesthesiology and cardiology literature. Reporting methodology standards in TEE examinations remain to be established.

Abstract
Mild paravalvular aortic insufficiency (AI) is common immediately after stentless bioprosthetic aortic valve replacement. Although resolution of paraprosthetic jets with protamine has been described, the predictability of resolution has not been addressed. Intraoperative transesophageal echocardiography was performed before and after protamine administration among 2 groups. The first group (n = 20) was used to define the prevalence and severity of paravalvular AI after stentless tissue AVR, and define a threshold value for jet size associated with resolution with protamine. A second group (n = 18) was used to prospectively test the determined threshold. Paravalvular AI occurred in 13 of 20 (65%) patients. Using a threshold value of 0.3 cm or less jet width, prospective testing revealed positive and negative predictive values for AI resolution with protamine of 93% (14 of 15) and 100% (3 of 3), respectively. Protamine administration is associated with resolution of small AI jets immediately after implantation of a stentless aortic bioprosthesis, with a jet width 0.3 cm or less strongly predictive of resolution.

Abstract
OBJECTIVE In essential hypertension, especially in concentric hypertrophy, global diastolic function is impaired. But, whether the left ventricular (LV) geometric pattern influences regional systolic and diastolic function or not, is unknown. This study was aimed to evaluate the influence of left ventricular geometric pattern on regional systolic and diastolic function in hypertensive patients. DESIGN Ninety untreated mild to moderate hypertensive patients were studied. M-mode parameters, standard Doppler and PW tissue Doppler indices were measured. Patients were divided into four groups according to left ventricular mass index and relative wall thickness: normal geometry (n = 16), concentric remodeling (n = 16), eccentric hypertrophy (n = 32) and concentric hypertrophy (n = 26). RESULTS Age, gender, body mass index, systolic and diastolic blood pressure were similar among groups. E/A ratio was significantly lower in the concentric hypertrophy group compared with the normal geometry group. Em velocity and Em/Am ratio in basal septum and Em velocity in basal inferior were statistically lower in the concentric hypertrophy group compared with the normal geometry group. In the concentric hypertrophy group, the number of segments with diastolic dysfunction was significantly higher compared with the normal geometry group. LV ejection fraction and regional S velocity could be compared among groups. CONCLUSION LV regional diastolic function is being impaired in concentric hypertrophy. LV regional systolic function does not show a difference according to the LV geometric pattern.

Abstract
OBJECTIVE To determine the value of intraoperative transesophageal echocardiography for the assessment of the pulmonary valve anatomy and the pulmonary autograft performance in patients undergoing the Ross procedure. DESIGN Open, prospective, observational survey. SETTING Favaloro Foundation, single institution. PARTICIPANTS Consecutive patients undergoing elective Ross procedure (n = 87). INTERVENTIONS Pulmonary valve function and anatomy were assessed by transesophageal echocardiography and the surgeon. Pulmonary autograft function was assessed after implantation. Regurgitation was considered mild (+/4), moderate (++/4), moderate-to-severe (+++/4), and severe (++++/4). Patients were restudied during midterm follow-up. MEASUREMENTS AND MAIN RESULTS The Ross procedure was done in 74 patients (85%). Overall mortality was 3.4%. Mean follow-up was 24 +/- 13 months. The Ross procedure was not done in 13 patients (15%): 6 patients had a bicuspid pulmonary valve, 6 patients had >3 mm fenestrations, and 1 patient had regurgitation. The surgeon diagnosed anomalies in the pulmonary valve through direct observation. Transesophageal echocardiography was not sensitive enough to diagnose pulmonary valve defects in 12 of 13 patients with anomalies. Pulmonary valve regurgitation was identified by intraoperative transesophageal echocardiography in only 1 patient. Autograft regurgitation was 1.07 +/- 0.35 at postoperative evaluation. At 1, 6, and 12 months, it was 1.25 +/- 0.7 (p = 0.18), 1.27 +/- 0.9 (p = 0.185), and 1.29 +/- 0.8 (p = 0.17). The difference in values was not statistically significant. Four patients (5.4%) showed an increase in regurgitation during the first transthoracic autograft control. CONCLUSION Intraoperative transesophageal echocardiography allows assessment of autograft performance after implantation. This method is not helpful, however, in detecting pulmonary valve anatomic anomalies.

Abstract
In this study, we sought to define the impact of intraoperative transesophageal echocardiography (IOTEE) among patients undergoing aortic valve replacement for severe aortic stenosis. We reviewed the clinical data and preoperative, intraoperative, and postoperative echocardiograms of all adults who underwent aortic valve replacement for aortic stenosis and had IOTEE between January 1993 and December 1996. There were 383 patients (223 men, 160 women; mean age, 69 years). Fifty-four (14%) of the 383 patients had mitral valve surgery at the time of aortic valve replacement. In 6 patients, mitral valve surgery was not planned but was added because of findings on IOTEE. In 25 patients, mitral valve surgery was canceled on the basis of the IOTEE. Additional information was found by IOTEE in 25 patients before and after bypass, altering the surgical plan in 18 of these 25 patients. Overall, IOTEE altered the planned operation in 49 (13%) of the 383 patients. These data support the routine use of IOTEE among patients undergoing aortic valve replacement for aortic stenosis.

Abstract
TEE overcomes many of the imaging constraints associated with transthoracic echocardiography for the assessment of valvular anatomy and function. Additional imaging artifacts and constraints associated with prosthetic valves are minimized or overcome with TEE. As such, TEE allows assessment of prosthetic valve anatomy and function and paraprosthetic anatomy, and serves as the diagnostic imaging modality of choice for patients with suspected prosthesis dysfunction or endocarditis.

Abstract
OBJECTIVE To determine the impact of intraoperative transesophageal echocardiography (IOTEE), an important adjunct in many types of cardiac surgical cases, on the surgical decisions made perioperatively in adult patients undergoing cardiac surgery. PATIENTS AND METHODS All adult patients who had cardiac surgery between 1993 and 1997 and who also had IOTEE were studied. New findings before and after cardiopulmonary bypass and alterations in the planned surgical procedure or management were documented prospectively. RESULTS A total of 3245 patients (60% men, 40% women; aged 18-93 years with a mean +/- SD age of 62 +/- 15 years) were included in the study. The most common operations performed were mitral valve repair (26%) and aortic valve replacement (22%). Over the 5-year period, 41% of patients had IOTEE. New information was found before bypass in 15% of patients, directly affecting surgery in 14% of the patients. The most common new prebypass information found was patent foramen ovale resulting in closure in the majority of patients. New information was found after bypass in 6% of the patients, resulting in a change in surgery or hemodynamic management in 4% of the total. The most common postbypass finding was valvular dysfunction with repeat bypass in most patients for re-repair or replacement. No major complications occurred. CONCLUSION In adult patients undergoing cardiac surgery, IOTEE provides important important information both before and after bypass that affects surgical and hemodynamic management.
