A transesophageal echocardiogram (TEE) is a diagnostic procedure that uses echocardiography to assess the hearts function. Echocardiography is a procedure used to assess the hearts function and structures. During the procedure, a transducer (like a microphone) sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed on the chest at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or echo off of the heart structures. The transducer picks up the reflected waves and sends them to a computer. The computer displays the echoes as images of the heart walls and valves.. A transesophageal echocardiogram is performed by inserting a probe with a transducer down the esophagus rather than placing the transducer on the chest. The TEE transducer works in the same manner as the one described above.. By inserting the transducer in the esophagus, TEE provides a clearer ...

Objective: To compare the value of current harmonic transthoracic and transesophageal echocardiography for assessing echocardiographic markers of thromboembolic risk and identify left atrial thrombi in patients with atrial fibrillation and atrial flutter prior to cardioversion and/or overdrive stimulation. Transesophageal echocardiography has been suggested for guiding cardioversion in patients with atrial fibrillation and atrial flutter, because of its high accuracy for identifying left atrial thrombi. More recent studies have demonstrated that harmonic echocardiography may allow transthoracic detection of left atrial thrombi and assessment of left atrial appendage function. Setting: Tertiary cardiac referral centre. 172 Patients with atrial fibrillation and/or atrial flutter who were scheduled for cardioversion and/or overdrive stimulation were examined both by harmonic transthoracic and multiplane transesophageal echocardiography by independent observers to assess left atrial chamber and ...

A transesophageal echocardiogram, or TEE (TOE in the United Kingdom, reflecting the spelling transoesophageal), is an alternative way to perform an echocardiogram. A specialized probe containing an ultrasound transducer at its tip is passed into the patients esophagus. This allows image and Doppler evaluation which can be recorded. It has several advantages and some disadvantages compared with a transthoracic echocardiogram (TTE). Specialty medicine professional organizations recommend against using transesophageal echocardiography to detect cardiac sources of embolization after a patients health care provider has identified a source of embolization and if that person would not change a patients management as a result of getting more information. Such organizations further recommend that doctors and patients should avoid seeking transesophageal echocardiography only for the sake of protocol-driven testing and to agree to the test only if it is right for the individual patient. The advantage ...

Objectives. This study was conducted to determine the implications of negative findings on a transesophageal echocardiographic study in which neither a vegetation nor an abscess is identified in patients with clinically suspected infective endocarditis.. Background. Echocardiography is the procedure of choice for evaluating suspected infective endocarditis in patients. Transesophageal echocardiography has been shown to be superior to transthoracic imaging. Although the importance of positive results or a diagnostic study is known, the significance of negative findings on a transesophageal study is not clear.. Methods. All transesophageal echocardlographic studies performed over a 2-year period for suspected infective endocarditis were reviewed and the clinical course of patients with an initially negative study result was assessed to determine their final diagnosis. Results. Of the 105 patients identified. 65 bad a negative transesophageal study result. In the majority of this group (56 of 65), ...

The aim of the study was to compare the accuracy of multiplane transesophageal echocardiography (TEE) with the more conventional biplane technique in the direct assessment of aortic valve area in patients with aortic stenosis. Short-axis images of the aortic valve adequate for measuring aortic valve area were obtained in all 81 patients studied by multiplane TEE but in only 56 of 64 patients (88%) using the biplane approach. The correlation coefficient for aortic valve area determined by multiplane TEE (r = 0.89; SEE = 0.04 cm2) was higher (p ...

Paraprosthetic AR following TAVI is of potential importance for two reasons. First, patients with longstanding isolated severe AS without AR before the procedure sometimes have poor hemodynamic tolerance of acute AR caused by the procedure, owing to what is typically a small, hypertrophied (noncompliant) left ventricle. Second, data suggest that patients with significant AR following TAVI have worse survival statistics compared to others who do not. The latter begs the question of whether it is the AR that increases mortality risk, or whether the presence of AR is a marker of other disease--most likely diffuse arterial calcification. This study confirms that dense and asymmetrical valve calcification, along with mismatch between the cross-sectional areas of the aortic valve annulus and of the device being deployed, portent a higher risk of postprocedural AR with this balloon-expandable device. It remains to be determined whether AR or the underlying calcification is of clinical ...

Cardioversion procedures are usually scheduled in advance, although if your symptoms are severe, you may need to have cardioversion in an emergency setting.. You typically cant eat or drink anything for about 8 hours before your procedure. Your doctor will tell you whether you should take any of your regular medications before your procedure. If you do take medications before your procedure, sip only enough water to swallow your pills.. Before cardioversion, you may have a procedure called a transesophageal echocardiogram (TEE) to check for blood clots in your heart, which can be dislodged by cardioversion, causing life-threatening complications. Your cardiologist will decide if you need a transesophageal echocardiogram before cardioversion.. In a transesophageal echocardiogram, your throat is numbed and a flexible tube containing a transducer is guided down your throat and into your esophagus, which connects your mouth to your stomach. From there, the transducer can obtain more-detailed images ...

with the advent of real-time 3-dimensional transesophageal echocardiography (3d tee), rapid creation of high-quality, true-to-life images of mitral valve anatomy and pathology has become possible in the vast majority of patients (1). In addition to common mitral valve lesions, such as degenerative mitral valve disease, 3D TEE is invaluable for characterizing less frequently encountered disorders, including endocarditis and its complications (2). Precise localization of leaflet perforations can be challenging on 2-dimensional images, particularly for non-experts. While the affected scallop can often be identified with the help of color Doppler, it may be difficult to pinpoint the site of perforation with respect to the leaflet tip. The addition of 3D TEE often provides clarity in this regard, helping to determine the feasibility of surgical repair. In this iPIX, we demonstrate the role of real-time 3D TEE in characterizing mitral leaflet perforations at various sites. Asterisks denote the aorta ...

Objectives. The aim of this study was to identify the mechanism and features of artifacts encountered during transesophageal echocardiography of the aorta.. Background. Artifacts are an important potential limitation of transesophageal echocardiography of the aorta.. Methods. The mechanism of the artifacts was examined by in vitro modeling. The frequency and clinical correlates of artifacts were examined by retrospective review of transesophageal echocardiograms in 36 patients with aortic pathologic lesions.. Results. Two classes of artifact were seen: linear artifacts in the ascending aorta, which may mimic intimal flaps, and mirror image artifacts in the transverse and descending thoracic aorta. Linear artifacts in the ascending aorta, seen in 44% of patients, were shown in vitro to be multiple path artifacts caused by reflection of ultrasound within the left atrium. Linear artifacts in the ascending aorta were associated with dilation of the ascending aorta and were more frequent when the ...

A mitral inflow method by single-plane combined the time-velocity integral of mitral inflow at the mitral annulus with the area of mitral annulus, assuming it to be a circular shape, by use of either the four- or the two-chamber view. With both views, a mitral inflow method by biplane combined the average of time-velocity integral of mitral inflow from the four- and the two-chamber views with the area of mitral annulus, assuming it to be an ellipsoid shape. The correlation coefficients between thermodilution and single-plane method of cardiac output were 0.81 (SEE = 0.72 L/min) ...

Faculty Electrical Engineering, Mathematics and Computer Science. Department Microelectronics & Computer Engineering. Programme Microelectronics. Date 2013-01-22. Abstract The motivation behind this thesis is that cardio-vascular diseases claim the highest number of lives each year globally. In order to enhance the accuracy in diagnosis, construction of 3D images of the heart is required. From these images, precise information can be obtained regarding the 3D anatomy of the heart and its functioning. Trans-Esophageal Echocardiography (TEE) is a promising technique to achieve this kind of precision in diagnosis. The objective of my thesis is to perform optimization at the system and circuit level, in order to improve power-efficiency and area-efficiency of the front-end receiver electronics. This electronic circuitry is integrated at the tip of a miniature TEE probe, which will be inserted through the esophagus close to the heart of the patient for diagnosis (via a gastroscopic tube). The signal ...

Before antibiotics were discovered, infective endocarditis was almost uniformly fatal. Although the prognosis is now markedly improved, it remains a disease with considerable mortality and morbidity. Patients with abscesses are much less likely to be cured with medical therapy alone. Thus, the early detection of abscesses might be useful in leading to surgery before complications, such as congestive heart failure, develop. Transthoracic echocardiography is the standard method for diagnosing vegetations, but it is not very effective in diagnosing abscesses. Recently, transesophageal echocardiography has been documented to improve the diagnosis of vegetations. On the basis of this study, transesopha- geal echocardiography is also useful for diagnosing abscesses. Although the results of this study are acceptable on the basis of the sensitivity and specificity, the predictive values reported must be adjusted for local circumstances. As noted by the authors, the population studied was skewed. First, ...

Abstract Transesophageal echocardiography (TEE) is a key diagnostic modality in patients with acute aortic dissections, yet its sensitivity is limited by the blind-spot caused by air in the trachea. After placement of a fluid-filled balloon in the trachea visualization of the thoracic aorta becomes possible. This method, modified TEE, has been shown to be an accurate test for the diagnosis of upper aortic atherosclerosis.. In this study it was demonstrated that modified TEE can reveal the blind-spot of conventional TEE. In patients with (suspected) aortic dissection it is thus possible to obtain a complete echocardiographic overview of the thoracic aorta and its branches. This is of specific merit in hemodynamically unstable patients who cannot undergo CT. Modified TEE can also guide the surgical management and monitor perfusion of cerebral arteries..

Introduction: Patients with atrial fibrillation (Afib) routinely undergo transesophageal echocardiogram (TEE) for evaluation of left atrial appendage (LAA) to rule out thrombus prior to undergoing cardioversion or pulmonary vein isolation (PVI). Cardiac MRI (CMR) is now increasingly used for evaluation of these patients for defining pulmonary vein anatomy prior to PVI. We hypothesized that 2D and 3D non-contrast and contrast CMR is as effective as TEE in evaluating the LAA thrombus while providing simultaneous comprehensive non-invasive evaluation of the pulmonary vein anatomy within a single exam.. Methods: Afib Pts (n=110, male=82) underwent TEE and non-contrast and contrast CMR prior to undergoing an initial PVI procedure. CMR was performed on 1.5T GE scanner and two blinded CMR experts analyzed the images. The CMR images were analyzed under two categories: 1) the 2D non-contrast cine images showing LAA in 2 chamber and orthogonal views 2) 3D atrial contrast source-images acquired during ...

The final diagnosis was AL (primary) amyloidosis and smoldering multiple myeloma with cardiac involvement. Treatment was started with CYBord (velcade, cytoxan, dexamethasone). Enoxaparin therapy was started for the left atrial appendage thrombus. Given major cardiac involvement, and a clinically estimated 5 yr overall survival of 40%, ICD implantation for primary prevention was not recommended. Perspective: Several key findings of cardiac amyloidosis were identified in this study. Atrial fibrillation is common in this population, for which real-time cine imaging was helpful. CMR has not gained widespread use for LAA thrombus detection, despite prior reports suggesting high sensitivity and specificity. This may be attributable to the overall low incidence of thrombus in study populations comparing CMR to transesopohageal echocardiography2. With the addition of three dimensional contrast MRA, which was not performed in this study, detection may approach that of transesophageal echocardiography. ...

TY - JOUR. T1 - The use of transesophageal echocardiography to guide sternal division for cardiac operations via mini-sternotomy. AU - Sardari, Fred F.. AU - Schlunt, Michelle L.. AU - Applegate, Richard Lee. AU - Gundry, Steven R.. PY - 1997. Y1 - 1997. N2 - Cardiac surgery utilizing the mini-sternotomy technique offers many advantages, including lessened pain and hospitalization. Mid-line upper sternotomy (or mini-sternotomy) can provide adequate exposure of the ascending aorta, the aortic root, the right atrial appendage and the dome of the left atrium. Inherent in providing adequate exposure is the level at which the sternum is Td off. The lower aspect of the sternotomy is Td off at the second, third, or fourth intercostal space depending on the patients anatomy. We describe a technique that uses transesophageal echocardiography to determine the precise location for Ting off the sternotomy, rather than approximating the sternotomy site by physical exam and chest radiograph. This ...

A 48-year-old man with a medical history of hypertension was admitted with acute dyspnea and pyrexia. Echocardiographic examination revealed a dilated and volume-overloaded left ventricle and severe mitral regurgitation due to ruptured chordae tendinae resulting in posterior leaflet prolapse. Blood cultures were negative. The patient was treated with antibiotics considering that he had a chest infection based on the admission chest x-ray, diuretics, and angiotensin converting enzyme inhibitors, and his clinical condition improved. Subsequently, he was referred for cardiac surgery. Coronary angiography demonstrated normal coronary anatomy, and he had mitral valve repair with placement of a 27-mm Duran flexible mitral ring. Postoperatively, he developed pyrexia. Numerous blood cultures were negative, but on the 14th postoperative day serological tests came back positive for Coxiella burnetti. He was treated with the combination of doxycycline and chloroquine. On the 25th postoperative day, he ...

Background: Transesophageal echocardiography (TEE) is often performed to explore an embolic source in ischemic stroke patients without atrial fibrillation (AF). The aim of this study was to elucidate the relationship between the ratio of transmitral flow velocity (E) and mitral annular velocity (e) measured by using TEE (E/e TEE) and prediction of new AF during hospitalization.. Method: We prospectively enrolled 170 patients with acute ischemic stroke without known atrial fibrillation at admission. Transthoracic echocardiography was performed to assess left atrial diameter, ejection fraction, and E/e. A subset of patients underwent TEE to explore an embolic source. We obtained the e at the lateral wall located near the left atrial appendage by using TEE. Baseline characteristics, stroke features, initial National Institutes of Health Stroke Scale (NIHSS) score, plasma and serum biomarkers included brain natriuretic protein (BNP), and imaging findings were recorded. We investigated factors to ...

A 76-year-old woman with a medical history of permanent atrial fibrillation (CHA2DS2-VASc stage 4) underwent left atrium (LA) appendage closure with a LARIAT device (SentreHEART, Redwood City, California). She was then maintained on aspirin only due to major bleeding during postoperative period. Two years later, she presented with a mechanical fall. Chest computed tomography with contrast, done as work-up for trauma, showed a large unenhanced LA mass (Figure 1A). She underwent further evaluation with transesophageal echocardiogram (TEE), which showed very severe LA dilatation (LA volume = 150 ml or 79 ml/m2), LA appendage occlusion, and a new, very large, sessile mass attached to the posterior wall of the LA (Figures 1B and 1C, Online Video 1). The mass did not enhance after contrast infusion (Figure 1D, Online Video 2). This mass was new compared to her prior TEE during the procedure and the findings were consistent with thrombus. She was treated with vitamin K antagonist and had no clinical ...

TY - JOUR. T1 - Transesophageal contrast echocardiography is not always the gold standard method in the identification of a patent foramen ovale: A clinical case. AU - Novo, Salvatore. AU - Costa, Francesco. AU - Lunetta, Monica. PY - 2015. Y1 - 2015. N2 - In the embryo, Eustachian valve is a crescent-shaped membrane extending from the lower margin of the inferior vena cava and the ostium of the coronary sinus into the right atrium toward fossa ovalis and tricuspid valve. At birth, after the functional closure of the foramen ovale, the Eustachian valve loses its function, reducing to an embryo remnant. According to growing evidence, a persistent Eustachian valve is a frequent finding in patients with a patent foramen ovale (PFO). By directing the blood from the inferior cava to the interatrial septum, it may prevent the spontaneous closure of PFO after birth and indirectly predispose to paradoxical embolism. Transesophageal contrast enhanced echocardiography (cTEE) is considered the gold ...

[more ▼]. OBJECTIVES: Intraoperative three-dimensional (3D) transesophageal echocardiography (TEE) has been suggested to be a valuable technique for the evaluation of the mechanisms of ischemic mitral regurgitation (IMR). Studies comparing multiplane two-dimensional (2D) with 3D TEE reconstruction of the mitral valve using the new mitral valve quantification (MVQ) software are lacking. We undertook a prospective comparison between multiplane 2D and 3D TEE for the assessment of IMR. METHODS: We evaluated echocardiographically 45 patients with IMR who underwent mitral valve surgery in our institution. 2D and 3D TEE examinations followed by a 3D offline assessment of the mitral valve apparatus were performed in all patients. Offline analysis of mitral valve ...

Introduction: The 2012 HRS/EHRA/ECAS guidelines encourage pre-procedural transesophageal echocardiography (TEE) prior to ablation for atrial fibrillation (AF), but acknowledge a lack of consensus in patients maintained on therapeutic warfarin before, during and after the procedure. This is partly because the incidence of left atrial appendage (LAA) thrombus is so low, that it is hard to draw clear conclusion regarding the characteristics of patients who develop thrombus. We hypothesize that the presence of low LAA emptying velocities, which predisposes to thrombus, and/or thrombus itself can be predicted in patients undergoing ablation, based upon clinical characteristics and transthoracic echocardiography (TTE). Methods: In this multicentre study, we undertook TTE and transesophageal echocardiograms (TEE) in 586 patients (age 59.9±0.4 years old, 64.5% male) undergoing catheter ablation for AF who were anticoagulated on warfarin (target international normalized ratio 2-3.5) for ≥3 consecutive weeks

Abstract. Left atrial appendage (LAA) thrombus is an accepted risk factor for ischemic stroke. Following a literature review we were unable to identify a study that determined the incidence of ischemic stroke in patients with a confirmed LAA thrombus. The purpose of this study was to establish the incidence of ischemic stroke in patients with a LAA thrombus confirmed on trans-oesophageal echocardiography (TOE). A ten year retrospective single centre study was conducted for the period March 2005 to February 2014 in St. Vincents University Hospital, Ireland. All TOE studies performed during this period were reviewed. A chart review was carried out on any patient who had a LAA thrombus, left atrial (LA) thrombus or pre-thrombus state identified. Charts were reviewed for documented neurological deficits consistent with ischemic stroke or transient ischemic attack within six months following TOE study. Overall 1903 TOE studies were reviewed. A total of 67 TOE studies detected a LAA thrombus, LA ...

To date, there have only been limited data on the prevalence of LA thrombus detection among patients with AF on NOAC therapy. In a subgroup analysis of patients in the RELY (Randomized Evaluation of Long Term Anticoagulant Therapy) study, the rates of LA thrombus detection among patients undergoing TEE before cardioversion were 1.2% to 1.8% for patients on dabigatran (14). In the ARISTOLE (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation) study, TEE data were available in 86 patients on apixaban and none of these patients had LA thrombus (15). In an analysis of patients undergoing cardioversions or catheter ablation of AF in the ROCKET AF (Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation) study, no TEE data were collected to assess rates of LA thrombus detection among patients on rivaroxaban (16).. In our study, the rate of LA thrombus detection among patients on ...

Methods and apparatus for closing a left atrial appendage are described. The methods rely on introducing a closure tool from a location beneath the rib cage, over an epicardial surface, and to the exterior of the left atrial appendage. The closure device may then be used to close the left atrial appendage, preferably at its base, by any one of a variety of techniques. A specific technique using graspers and a closing loop is illustrated.

Atrial fibrillation is a common condition encountered in the cardiology inpatient service. It is associated with atrial thrombosis, which requires exclusion using transesophageal echocardiogram (TEE) before planned cardioversion. TEE can be operator dependent with a reported sensitivity of 93-100 %.1A significantly elevated D-dimer can help the TEE operator to look for intra-atrial clots more carefully in the absence of any other cause for an elevated D-dimer. This ultimately will increase operator efficiency. A 56 year old white male, status post renal transplant and CABG for 3 vessel CAD and a prior history of MRSA bacteremia, presented with chief complaints of nausea, malaise and lethargy. Examination revealed a frail white male in moderate distress, regular heart rate and rhythm with a grade III/VI SEM at the LLSB radiating to the carotids. He was admitted with the presumptive diagnosis of uremic syndrome secondary to transplant failure on account of elevated BUN and CR and was scheduled for ...

A 63-yr-old patient presented with a preoperative diagnosis of aortic stenosis and pulmonary stenosis for aortic valve (AV) replacement and possible pulmonary valve (PV) repair. His symptoms included chest heaviness and shortness of breath. A preoperative transthoracic echocardiogram demonstrated calcified tri-leaflet AV with severe stenosis and a peak pulmonic flow velocity of 3.7 m/s. Cardiac catheterization confirmed these findings with a right ventricular (RV) pressure of 71/−3 mm Hg, pulmonary artery (PA) pressure of 26/11 mm Hg and a peak pulmonic gradient of 45 mm Hg. Intraoperative transesophageal echocardiography (TEE) was performed and the PV was interrogated in several planes. The midesophageal (ME) RV inflow-outflow view was suboptimal due to shadowing from the calcified AV. Similarly, the ME AV short axis (SAX) view was obtained and the probe was gradually withdrawn to image the PA. This view was inadequate because of bronchial interference. Subsequently, the upper esophageal ...

Once the patient is on bypass, a cut is made in the aorta and a cross clamp applied. The surgeon then removes the patients diseased aortic valve and a mechanical or tissue valve is put in its place. Once the valve is in place and the aorta has been closed, the patient is taken off the heart-lung machine. Transesophageal echocardiogram (TEE, an ultra-sound of the heart done through the esophagus) can be used to verify that the new valve is functioning properly. Pacing wires are usually put in place, so that the heart can be manually paced should any complications arise after surgery. Drainage tubes are also inserted to drain fluids from the chest and pericardium following surgery. These are usually removed within 36 hours while the pacing wires are generally left in place until right before the patient is discharged from the hospital ...

Procedural sedation and analgesia, previously referred to as conscious sedation, is defined as a technique of administering sedatives or dissociative agents with or without analgesics to induce a state that allows the patient to tolerate unpleasant procedures while maintaining cardiorespiratory function. The American Society of Anesthesiologists defines the continuum of sedation as follows: This technique is often used in the emergency department for the performance of painful or uncomfortable procedures. Common purposes include: setting fractures draining abscesses reducing dislocations performing endoscopy for cardioversion during various dental procedures during transesophageal echocardiogram and certain imaging or minor procedures where the patient is unable (or unwilling) to keep still-especially children Propofol Ketamine Etomidate Midazolam Fentanyl Remifentanil continue infusion Morphine Ketamine: Small doses of ketamine have been found to be safer than fentanyl when used in ...

Objective: The benefit of the sitting position for surgery of the posterior fossa and cervical spine is still matter of controversy. The literature suggests a decline in the use of this position in neurosurgery. However, there are undisputable advantages of the sitting position, such as the reduction of blood loss or reduced rate of brain swelling. In our study we analyzed the results in a large series. We compared the incidence of venous air embolism (VAE) as recognized with different monitoring techniques and the severity of complications.. Methods: We retrospectively analyzed 521 patients, who underwent surgery for different posterior fossa pathologies and cervical spine pathologies in the sitting position in our institution from 1995 to 2009. Intra operative monitoring for VAE included end-tidal CO2 level, Doppler ultrasound or intraoperative transesophageal echocardiography (TEE). We definded VAE as a decline of the end-tidal CO2 levels by more than 4 mm Hg, a characteristic sound in the ...
