THE use of transesophageal echocardiography for intraoperative monitoring of cardiac function is increasing. Complications are rare. Oropharyngeal injury and hypopharyngeal perforation during difficult insertion of the echoprobe in anesthetized patients have been reported. [1,2] One case of perforation of the cervical esophagus in an awake patient after multiple attempts at insertion of the ech...

BACKGROUND The overall performance of available mechanical intravascular ultrasound catheters for fetal transesophageal echocardiography during fetoscopic fetal cardiac interventions in sheep has been limited by radioelectronic interference, low system frame rates, and low acoustic outputs. Therefore, a more reliable device is desired for human fetoscopic surgical procedures. METHODS AND RESU...

In vivo assessment of cardiac structure and function in small animals is an important experimental goal, but currently available techniques have significant limitations. A commercially available intravascular ultrasound (IVUS) system was adapted to perform transesophageal echocardiography (TEE) in rats. Twelve Sprague-Dawley rats (270-370 g) were anesthetized with intraperitoneal pentobarbital ...

L'echocardiographie trouve de plus en plus une place importante dans L'evaluation des di­verses cardiopathies tant acquises que Congeni­tales. Cette technique, non sanglante et atrau­matique a surtout l'intcrrct de Pouvoir etre re­pete a volonte.  Ainsi l'echoc'.lrdiographie rend de servic-:: certains dans L'etablissement du bilan preopera­toin: des cctrdiooathies valvulaires sifrequente en Ir...

introduction: although surgery is the corner stone of treatment for esophageal cancer, there have been widespread efforts to find new methods of treatment .therefore, neoadjuant crt certainly increases the rate of resectability and 3 years survival .in our research, we reviewed effects of neoadjuant rct on short-term complications and hospital mortalities. materials & methods: 114 cases of esop...

achalasia is a primary motor disorder of the esophagus, in which esophageal emptying is impaired. diagnosis of achalasia is based on clinical findings and confirmed by radiologic, endoscopic and manometric evaluations. several treatments for achalasia have been introduced. we searched the pubmed database for original articles and meta-analyses about achalasia to summarize the current knowledge ...

INTRODUCTION Anomalies of the aortic arch are frequent congenital malformations, which rarely form partial or complete vascular rings. A rare form of vascular ring is the encircling, or circumflex, aortic arch. CASE REPORT A 19-month-old boy, with no respiratory symptoms, was referred for ventricular septal defect (VSD) repair. Cardiac magnetic resonance imaging and echocardiography confirmed...

Introduction Current standard techniques for imaging the thoracic aorta include CT, standard body-coil MRI, transesophageal echocardiography (TEE), and contrast aortography. Each of these techniques suffers some limitation in its ability to allow detailed mapping of the aortic wall and its anatomic and functional lesions. Body-coil MRI and CT lack adequate resolution of the aortic wall for prec...

positive defects are mainly observed in the inferoposterior, inferior, and apical myocardium, which could be explained by differences in regional blood flow during ventricular pacing [4] . Importantly, these perfusion abnor malities are more prominent during physical exercise compared with pharmacological stress using dipyridamole or adenosine [5] . Stress echocardiography is usually performed ...
