Intraoperative transesophageal echocardiography is a minimally invasive monitoring tool that can provide real-time visual information on ventricular function and hemodynamic volume status in patients undergoing liver transplantation. The American Association for the Study of Liver Diseases states that transesophageal echocardiography should be used in all liver transplant candidates in order to assess chamber sizes, hypertrophy, systolic and diastolic function, valvular function, and left ventricle outflow tract obstruction...

BACKGROUND Carbon dioxide (CO2) is believed to be the safest gas for laparoscopic surgery, which is a standard procedure. We experienced severe cerebral infarction caused by paradoxical CO2 embolism during laparoscopic liver resection with injury of the hepatic vessels despite the absence of a right-to-left systemic shunt. CASE REPORT A 60-year-old man was diagnosed with hepatocellular carcinoma in the right hepatic lobe secondary to alcoholic liver disease. We planned the laparoscopy-assisted liver resection...

BACKGROUND: The diagnosis of thrombus in the left atrium in patients with persistent atrial fibrillation (AF) and may be inconsistent because of variability in thrombus morphology. In some cases it is challenging and requires unusual approach. New Doppler-derived methods might be helpful to identify such thrombi. We evaluated quantitative differences in mechanical function of the left atrial appendage (LAA) basal segments using tissue Doppler imaging (TDI)and speckle tracking echocardiography (STE) in patients with non-valvular AF with and without LAA thrombus and compared them with SR patients...

BACKGROUND: 2D-transesophageal echocardiography (TEE) is routinely performed to guide percutaneous ASD closure in children. We aimed to assess whether two-dimensional (2D)-transthoracic echocardiography (TTE) is a safe alternative for assessment and guidance of atrial septal defect (ASD) closure in unselected children. METHODS: We performed a retrospective single-center study including 389 consecutive children aged less than 15-year-old who underwent percutaneous ASD closure under 2D-TEE (1998-2005, n=133) or 2D-TTE (2005-2014, n=256)...

BACKGROUND: This study aimed to investigate the value of left atrial (LA) strain and strain rate (S/SR) by transthoracic echocardiography (TTE) in predicting left atrial appendage (LAA) stasis, in order to find a way for LAA stasis screening which is easily performed in patients with nonvalvular atrial fibrillation (NVAF). METHODS: One hundred and thirty NVAF patients prepared for AF ablation were enrolled. TTE and transesophageal echocardiography (TEE) were performed in all patients...

Hemangiomas are rarely found in the heart and pericardial involvement is even more rare. We report a case of primary pericardial hemangioma, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images. Our case also highlights the importance of systematic cropping of the 3D datasets in making a diagnosis of pericardial hemangioma with a greater degree of certainty. In addition, we also provide a literature review of the features of cardiac/pericardial hemangiomas in a tabular form...

BACKGROUND: Metastatic cardiac tumors are far more common than primary tumors. Although the hematogenous spread of osteosarcoma is well known, the imaging findings of cardiovascular involvement by osteosarcoma are seldom reported and can be difficult to recognize. CASE PRESENTATION: A 21-year-old man of African descent presented to our center complaining of shortness of breath, awareness of heart beats, easy fatigability, swelling of lower limbs, and left-side chest discomfort for the past 6 months getting worse for the last 3 months prior to his third readmission...

Loeffler endocarditis is a complication of hypereosinophilic syndrome resulting from eosinophilic infiltration of heart tissue. We report a case of Loeffler endocarditis in which three-dimensional transthoracic and transesophageal echocardiography provided additional information to what was found by two-dimensional transthoracic echocardiography alone. Our case illustrates the usefulness of combined two- and three-dimensional echocardiography in the assessment of Loeffler endocarditis. In addition, a summary of the features of hypereosinophilic syndrome and Loeffler endocarditis is provided in tabular form...

A 39-year-old woman underwent uneventful percutaneous occlusion of an ostium secundum atrial septal defect (ASD) with a 22 mm Ultrasept ASD Occluder(®). Transesophageal echocardiography (TEE) performed two years after implantation revealed a de novo residual left-to-right shunt through the correctly implanted device. Three-dimensional transesophageal echocardiography (3D TEE) further clarified this finding by showing a perforation of the device membrane coating. The patient underwent transcatheter closure of the residual shunt with a 20 mm Ultrasept PFO(®) device...

Transthoracic echocardiography (TTE), computed tomography (CT) and magnetic resonance (MR) cannot always clearly identify angiosarcoma. A 22 year old woman presented with dyspnea. Preoperative TTE showed no tumor, and CT and MR both gave the impression that an extra-cardiac, mediastinal tumor was present. Transesophageal echocardiography (TEE), performed during surgery showed an intra-cardiac tumor, which was a well-delineated mass at the intra-ventricular groove of the right heart and surrounding the superior vena cava...

PURPOSE: Aortic valve area (AVA) is usually estimated by the continuity equation (CE) in which the left ventricular outflow tract (LVOT) area is calculated assuming a circular shape. This study aimed to compare measurements of LVOT area using standard 2D transthoracic echocardiography (2DTTE), 3D transesophageal echocardiography (3DTEE), and multidetector computed tomography (MDCT) and assess their relative impact on AVA estimated by the CE. METHODS AND RESULTS: We prospectively enrolled 60 patients with severe aortic stenosis (AS) referred for transcatheter aortic valve replacement (TAVR) who systematically underwent 2DTTE, 3DTEE, and MDCT...

The case of a 24-year-old male with complaints of migraine headaches was referred for echocardiography. The rest of medical history was unremarkable. Agitated saline contrast bubble study showed evidence of a right to left intracardiac shunt, probably secondary to a patent foramen ovale. Results of a transesophageal echocardiogram suggested the possibility of an anomalous venous circulation and eventually identified as anomalous left-sided superior vena cava with cardiac magnetic resonance imaging.

We compared transcranial Doppler (TCD) with transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) for the detection of right to left communication (RLC) in the heart. All patients explored from 2013 to 2016 in a vascular medicine unit to detect RLC by TCD were included. Right to left communication was detected by TCD monitoring for microembolic signals after intravenous injection of agitated 5% glucose and air. One hundred one patients were explored for RLC by TCD, 64 by TEE (not possible in 10, bubble injection in 51), and 93 by TTE because of unexplained stroke or arterial thrombosis (51 males, 50 females, age 51...

BACKGROUND: Previous studies have identified ABO blood groups as predictors of thromboembolic diseases. In patients with atrial fibrillation (AF), however, potential association between ABO blood groups and the risk of left atrial (LA) and/or left atrial appendage (LAA) thrombogenic milieu (TM) has not been established. METHODS: This is a retrospective case-control study that included 125 consecutive patients with non-valvular atrial fibrillation (NVAF) plus TM, as evidenced by transesophageal echocardiography (TEE) during a period from1 January 2010 to 31 December 2016...

Aortic intramural hemorrhage (IMH) is one of the disease processes that comprise the spectrum of acute aortic syndrome (AAS) with clinical manifestations and a mortality rate similar to those of classic aortic dissection (AD). However, IMH should be considered as a distinct disease entity rather than a precursor to classic dissection because of differences in their pathology, etiology, natural history, and imaging findings. Multidetector computed tomography (CT) is recommended as the first-line diagnostic imaging modality for IMH, but transesophageal echocardiography (TEE) and magnetic resonance imaging (MRI) are also helpful...

Anesthetic experience in frontotemporal dementia (FTD) with severe hypotension associated autonomic dysfunction has not yet been reported. Here in case, we report on the case of treatment with vasopressin to refractory hypotension in FTD patient. A 54-year-old male presented with a ten-year history of FTD with frequent syncope. The patient was scheduled to undergo subtotal gastrectomy for resection of stomach cancer. During the operation, sudden hypotension occurred and it was refractory to fluid and 1 unit of blood resuscitation and did not respond to catecholamine...

We report on a 32-year-old male patient with acute left-hemispheric stroke caused by embolism due to infective endocarditis affected from the HACEK group. Additionally, atypical findings from the transesophageal echocardiography (TEE) which showed fluttering structures belonging to the papillary muscle could be proven as infectious agents with the help of a glucose positron emission tomography (PET) scan. TEE controls showed increasing vegetation involving the mitral valve so that surgery became necessary. The current work reflects, in detail, the emergent clinical course of this young patient, suffering from both an unusual localization and an infrequent cause of endocarditis and focuses on an actual view to the literature...

Intracardiac echocardiography (ICE) is used in humans for percutaneous interventional procedures, such as transcatheter device closures. Intracardiac echocardiography provides high-resolution imaging of cardiac structures with two-dimensional, M-mode, Doppler, and also three-dimensional modalities. The present report describes application of ICE during transcatheter occlusion of patent ductus arteriosus using a canine ductal occluder in a dog for which transesophageal echocardiography could not provide an optimal acoustic window...
