Project description:PURPOSE:The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS:Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability. Its use extends to include moderate-risk procedures for patients with significant cardiac diseases such as low ejection fraction, hypertrophic cardiomyopathy, severe valve lesions, or congenital heart disease. Vascular procedures involving the aorta, blunt trauma, and liver transplantation are all examples of procedures that may benefit from TEE. Transesophageal echocardiography examination allows assessment of volume status, ventricular function, diagnosis of gross valvular pathology and pericardial tamponade, as well as close monitoring of cardiac output, response to therapy, and the impact of ongoing surgical manipulation. In patients with unexplained and unexpected hemodynamic instability, "rescue TEE" can be used to help identify the underlying cause. CONCLUSIONS:Perioperative TEE is emerging as a preferred tool to manage hemodynamics in high-risk procedures and in high-risk patients undergoing non-cardiac surgery. A rescue TEE examination protocol is a helpful approach for early identification of the etiology of hemodynamic instability.

Project description:BackgroundThe impact of utilization of intraoperative transesophageal echocardiography (TEE) at the time of isolated coronary artery bypass grafting (CABG) on clinical decision making and associated outcomes is not well understood.ObjectivesThe purpose of this study was to determine the association of TEE with post-CABG mortality and changes to the operative plan.MethodsA retrospective cohort study of planned isolated CABG patients from the Society of Thoracic Surgeons Adult Cardiac Surgery Database between January 1, 2011, and June 30, 2019, was performed. The exposure variable of interest was use of intraoperative TEE during CABG compared with no TEE. The primary outcome was operative mortality. The association of TEE with unplanned valve surgery was also assessed.ResultsOf 1,255,860 planned isolated CABG procedures across 1218 centers, 676,803 (53.9%) had intraoperative TEE. The percentage of patients receiving intraoperative TEE increased over time from 39.9% in 2011 to 62.1% in 2019 (p trend <0.0001). CABG patients undergoing intraoperative TEE had lower odds of mortality (adjusted odds ratio: 0.95; 95% confidence interval: 0.91 to 0.99; p = 0.025), with heterogeneity across STS risk groups (p interaction = 0.015). TEE was associated with increased odds of unplanned valve procedure in lieu of planned isolated CABG (adjusted odds ratio: 4.98; 95% confidence interval: 3.98 to 6.22; p < 0.0001).ConclusionsIntraoperative TEE usage during planned isolated CABG is associated with lower operative mortality, particularly in higher-risk patients, as well as greater odds of unplanned valve procedure. These findings support usage of TEE to improve outcomes for isolated CABG for high-risk patients.

Project description:BackgroundDespite recommendations regarding the use of intraoperative transesophageal echocardiography (TEE), there is no randomized evidence to support its use in cardiac valve surgery. The purpose of this study was to compare the clinical outcomes of patients undergoing open cardiac valve repair or replacement surgery with and without transesophageal echocardiographic monitoring. The hypothesis was that transesophageal echocardiographic monitoring would be associated with lower 30-day mortality and shorter length of hospitalization.MethodsIn this observational retrospective cohort study, Medicare claims were used to test the association between perioperative TEE and 30-day all-cause mortality and length of hospitalization among patients undergoing open cardiac valve repair or replacement surgery between January 1, 2010, and October 1, 2015. Baseline characteristics were defined by inpatient and outpatient claims. Medicare death records were used to ascertain 30-day mortality. Statistical analyses included regression models and propensity score matching.ResultsA total of 219,238 patients underwent open cardiac valve surgery, of whom 85% underwent TEE. Patients who underwent TEE were significantly older and had greater comorbidities. After adjusting for patient demographics, clinical comorbidities, surgical characteristics, and hospital factors, including annual surgical volume, the TEE group had a lower adjusted odds of 30-day mortality (odds ratio, 0.77; 95% CI, 0.73 to 0.82; P < .001), with no difference in length of hospitalization (<0.01%; 95% CI, -0.61% to 0.62%; P = .99). Results were similar across all analyses, including a propensity score-matched cohort.ConclusionsTransesophageal echocardiographic monitoring in cardiac valve repair or replacement surgery was associated with lower 30-day risk-adjusted mortality, without a significant increase in length of hospitalization. These findings support the use of TEE as routine practice in open cardiac valve repair or replacement surgery.

Project description:Although only limited scientific evidence exists promoting the use of transesophageal echocardiography (TEE) in non cardiac surgery, several recent studies have documented its usefulness during liver surgery.In the present case study, through the use of color Doppler TEE, compression of the inferior vena cava and the right hepatic vein was clearly evident, as was their restoration after surgery.TEE should be encouraged in patients undergoing liver resection, not only for hemodynamic monitoring, but also for its ability to provide information about the anatomy of the liver, its vessels, and inferior vena cava patency.

Project description:BackgroundIn cardiac surgical procedures, patients carrying high-risk profiles are prone to encompass complicated cardiopulmonary bypass (CPB) separation. Intraoperative transesophageal echocardiography (TEE), a readily available tool, is utilized to detect cardiac structural and functional pathologies as well as to facilitate clinical management of CPB separation, especially in the episodes of hemodynamic compromise. However, the conventional TEE examination, always performed in a liberal fashion without any restriction of view acquisition, is relatively time-consuming; there appear its flaws in the context of critically severe status. We therefore developed the perioperative rescue transesophageal echocardiography (PReTEE), a simplified three-view TEE protocol consisting of midesophageal four chamber, midesophageal left ventricular long axis, and transgastric short axis.MethodsThis is a single-center and randomized controlled trial which will be implemented in Peking Union Medical College Hospital, Beijing, China. A total of 46 TEE scans are schemed to be performed by 6 operators participating in and randomly assigned to either the PReTEE or the conventional TEE group. This study is purposed to investigate whether the efficiency of discriminating leading causes of difficult CPB wean-off can be significantly improved via an abbreviated sequence of TEE views. The primary outcome of interest is the difference between the groups of PReTEE and the conventional TEE in the successful discrimination of etiologies in specified 120 s. Cox proportional hazards model will be further employed to calculate the outcome difference.DiscussionThe estimated results of this trial are oriented at verifying whether a simplified TEE exam sequence can improve the efficiency of etiologies discrimination during CPB separation in cardiac surgery.Trial registrationClinicalTrials.gov NCT05960552.

Project description:Introduced in 1977, transesophageal echocardiography (TEE) offered imaging through a new acoustic window sitting directly behind the heart, allowing improved evaluation of many cardiac conditions. Shortly thereafter, TEE was applied to the intraoperative environment, as investigators quickly recognized that continuous cardiac evaluation and monitoring during surgery, particularly cardiac operations, were now possible. Among the many applications for perioperative TEE, this review will focus on four recent advances: three-dimensional TEE imaging, continuous TEE monitoring in the intensive care unit, strain imaging, and assessment of diastolic ventricular function.

Project description:Pulmonary tumor embolization from renal cell carcinoma is associated with severe cardiopulmonary morbidity and high perioperative mortality rates. We report the case of a 71-year-old woman who presented with right-sided abdominal pain. Magnetic resonance images revealed a mass originating from the upper pole of the right kidney and extending into the infrahepatic portion of the inferior vena cava. Transesophageal echocardiography was continuously used to monitor the mass during intended radical nephrectomy and tumor resection. When the right kidney was mobilized, intracaval thrombus detached and migrated to the patient's right atrium, causing severe hemodynamic instability. After emergent sternotomy and during the initiation of cardiopulmonary bypass, the mass was no longer echocardiographically detectable in the heart; it was soon removed completely from the left pulmonary artery. The mass was a renal cell carcinoma. We recommend the use of transesophageal echocardiography as an efficient diagnostic tool in the early detection of pulmonary tumor embolization during the resection of renal cell carcinoma that involves the inferior vena cava.

Project description:RationalePoint-of-care ultrasound is widely used in patients with cardiac arrest, allowing for diagnosing, monitoring, and prognostication as well as assessing the effectiveness of the chest compressions. However, the detection of intraoperative cardiac arrest by Point-of-care ultrasound was rarely reported.Patient concernsA 21-year-old male with Marfan syndrome which manifested Valsalva sinus aneurysms was admitted for aortic valve replacement. After endotracheal intubation, TEE transducer was inserted to evaluate the cardiac structure and function with different views. Severe aortic valve regurgitation was observed in the mid-esophageal aortic valve long and short axis view.DiagnosisTEE showed that cardiac contraction was nearly stopped, the spontaneous echo contrast was obvious in the left ventricular and hardly any blood was pumped out from the heart despite the ECG showing normal sinus rhythm with HR 61 beats/min. Meanwhile, the IBP was dropped to 50/30 mm Hg.InterventionsChest compressions were started immediately and epinephrine 100 μg was given intravenously. After 30 times of chest compressions, TEE showed that cardiac contractility increased and the stroke volume was improved in the TG SAX view.OutcomesThe patient was discharged 18 days later in a stable condition.LessonsContinuous echocardiography monitoring may be of particular value in forewarning and detecting cardiac arrest in high-risk patients.

Project description:BackgroundLibman-Sacks endocarditis, characterized by Libman-Sacks vegetations, is common in patients with systemic lupus erythematosus and is commonly complicated with embolic cerebrovascular disease. Thus, accurate detection of Libman-Sacks vegetations may lead to early therapy and prevention of their associated complications. Although two-dimensional (2D) transesophageal echocardiography (TEE) has high diagnostic value for detection of Libman-Sacks vegetations, three-dimensional (3D) TEE may allow improved detection, characterization, and clinical correlations of Libman-Sacks vegetations.MethodsTwenty-nine patients with systemic lupus erythematosus (27 women; mean age, 34 ± 12 years) prospectively underwent 40 paired 3D and 2D transesophageal echocardiographic studies and assessment of cerebrovascular disease manifested as acute clinical neurologic syndromes, neurocognitive dysfunction, or focal brain injury on magnetic resonance imaging. Initial and repeat studies in patients were intermixed in a blinded manner with paired studies from healthy controls, deidentified, coded, and independently interpreted by experienced observers unaware of patients' clinical and imaging data.ResultsThe results of 3D TEE compared with 2D TEE were more often positive for mitral or aortic valve vegetations, and 3D TEE detected more vegetations per study and determined larger sizes of vegetations (P ≤ .03 for all). Also, 3D TEE detected more vegetations on the anterior mitral leaflet, anterolateral and posteromedial scallops, and ventricular side or both atrial and ventricular sides of the leaflets (P < .05 for all). In addition, 3D TEE detected more vegetations on the aortic valve left and noncoronary cusps, coronary cusps' tips and margins, and aortic side or both aortic and ventricular sides of the cusps (P ≤ .01 for all). Furthermore, 3D TEE more often detected associated mitral or aortic valve commissural fusion (P = .002). Finally, 3D TEE detected more vegetations in patients with cerebrovascular disease (P = .01).ConclusionsThree-dimensional TEE provides clinically relevant additive information that complements 2D TEE for the detection, characterization, and association with cerebrovascular disease of Libman-Sacks endocarditis.
