BACKGROUND: Segmental analysis of diseased mitral valves is important to predict a successful surgical valve repair. An assessment was made of the comparative accuracy of intraoperative three-dimensional (3D) and two-dimensional (2D) transesophageal echocardiography (TEE) in the evaluation of mitral valve lesions when compared with intraoperative surgical segmental analysis. METHODS: A total of 42 consecutive patients (12 females, 30 males; mean age 70.5 ± 14 years) with severe mitral valve regurgitation due to degenerative disease and who underwent mitral valve repair was enrolled in the study...

We report a case of chronic dissecting thoracoabdominal aneurysm with intraoperative retrograde aortic dissection and rupture at proximal descending aorta, which was successfully treated by echoguided stent-graft insertion. An 82-year old male underwent thoracoabdominal aortic replacement for dilatation of infra-diaphragmatic aorta. Under F-F bypass, his thoracoabdominal aorta was replaced by a Dacron graft with 4-branches. After he weaned from F-F bypass, we found massive bleeding from proximal descending aorta...

Intravenous leiomyomatosis (IVL) is a condition in which leiomyoma originating from uterine myoma or intrauterine venous walls develops intravenously. A single-stage operation was planned by the departments of gynecology and cardiovascular surgery for a patient in which the IVL was extended across the tricuspid valve. It was possible to safely perform perioperative care with continued evaluation of the tumor position and intravascular volume through the use of transesophageal echocardiography (TEE). TEE can be useful in the intraoperative care of patients with intracardiac tumor extension as in this case...

A 74-year-old female underwent an uneventful bilateral thoracoscopic maze procedure for persistent atrial fibrillation with continuous transesophageal echocardiographic (TEE) guidance. She presented six weeks later with persistent fever and focal neurological signs. Computed tomography of the thorax revealed air in the posterior LA, raising suspicion for an abscess versus an atrioesophageal fistula (AEF). Before undergoing an exploratory median sternotomy, an esophagogastroduodenoscopy (EGD) was performed by the surgeon to check for any esophageal pathology...

BACKGROUND: Previous studies have demonstrated that three-dimensional (3D) transesophageal echocardiography (TEE) is an alternative to multi-detector computed tomography (MDCT) for aortic valve sizing in transcatheter aortic valve replacement (TAVR). However, conventional cross-sectional analysis of aortic annulus by 3D TEE has some limitations such as lengthy analytical time. A novel software for automated valve measurement has been developed for 3D TEE. We evaluated the accuracy and analytical time of aortic annular measurements using this novel automated software in the clinical setting...

BACKGROUND: Patients undergoing cardiac surgery need extensive and invasive monitoring, which needs to be individually adapted for each patient and requires a diligent risk-benefit analysis. The use of a pulmonary artery catheter (PAC) seems to be justifiable in certain cases; therefore, the preoperative diagnosis of pulmonary hypertension represents an indication for perioperative monitoring with PAC in the S3 guidelines of the German Society for Anesthesiology and Intensive Care Medicine (DGAI)...

Orthotopic liver transplantation (OLT) is characterized by significant hemodynamic disturbances and anesthetic challenges. Intraoperative transesophageal echocardiography (TEE) can be used to guide management during these procedures. This review examines the role of echocardiography during OLT, presents common TEE findings during each phase of OLT, and discusses the benefits demonstrated with TEE use and the safety of TEE in this patient population. Finally, the authors propose an algorithm for the safe use of TEE during OLT...

Intraoperative use of transesophageal echocardiography (TEE) has become commonplace in high-risk noncardiac surgeries but the balance of benefits and harms remains unclear. This systematic review investigated the comparative effectiveness and harms of intraoperative TEE in noncardiac surgery. We searched Ovid MEDLINE, PubMed, EMBASE, and the Cochrane Library from 1946 to March 2017. Two reviewers independently screened the literature for eligibility. Studies were assessed for the risk of selection bias, confounding, measurement bias, and reporting bias...

Masses in and near the interatrial septum may be either benign or malignant. The most common mass near the interatrial septum is lipomatous atrial septal hypertrophy (LASH). LASH can be present in patients with intracardiac malignancies, myxomas, lipomas, or other cardiac masses. It is important to recognize the transesophageal echocardiography (TEE) characteristics of these pathologies to arrive at an accurate diagnosis with an appropriate plan for intraoperative resection. At the authors' institution, patients have been referred for surgery due to a finding of significant LASH masquerading as a left atrial myxoma...

Supported by a growing number of studies and case reports in the literature, perioperative use of TEE in non-cardiac cases has significantly increased the past two decades. The utility of TEE in monitoring hemodynamic, and diagnosing causes of hypotension refractory to conventional therapy, have made it an almost indispensible tool during major surgeries, such liver transplantation. Despite this fact, compared to the adult population, there is a lack of an equivalent amount of literature on the perioperative use of TEE in pediatric cases...

Although the occurrence of stroke in patients undergoing coronary artery bypass grafting (CABG) is decreasing, it remains an important concern. Therefore, it is important to identify and adopt strategies that can decrease the incidence of stroke in these patients. One of the strategies that have demonstrated the potential to decrease the rate of post-CABG stroke is an assessment of aorta for atherosclerosis before surgery and changing the surgical plan accordingly to minimize the stroke risk. This assessment can be done through palpation of the aorta, transesophageal echocardiography (TEE), and epiaortic ultrasound scanning (EAS)...

Objective: Normative values of left ventricular (LV) end-diastolic area and diameter (EDA and EDD) for intraoperative transoesophageal echocardiography (TEE) have not been established. We aimed to define the ranges of LV EDA and EDD for intraoperative TEE examinations in patients undergoing coronary artery bypass graft (CABG) surgery. Methods: A MEDLINE search for studies reporting LV EDA and EDD in CABG patients was performed. Individual-level dataset from 333 anaesthetised and mechanically ventilated patients with preserved LV function (study population) were received from 8 studies...

OBJECTIVE: Pulmonary artery catheters (PACs) have routinely been positioned by wedging into the pulmonary artery before pulling back 1-2 centimeters or advancing the PAC several centimeters after achieving a pulmonary artery waveform. A rare, major complication is pulmonary artery rupture. This study presents transesophageal echocardiography (TEE) for PAC placement by leaving the catheter tip at the one o'clock position, upper window short-axis view of the ascending aorta at the bifurcation of the pulmonary artery (TEE distance)...

BACKGROUND: Estimation of cardiac output (CO) is essential in the treatment of circulatory unstable patients. CO measured by pulmonary artery catheter thermodilution is considered the gold standard but carries a small risk of severe complications. Stroke volume and CO can be measured by transesophageal echocardiography (TEE), which is widely used during cardiac surgery. We hypothesized that Doppler-derived CO by 3-dimensional (3D) TEE would agree well with CO measured with pulmonary artery catheter thermodilution as a reference method based on accurate measurements of the cross-sectional area of the left ventricular outflow tract...
