This report demonstrates the method of resection of a left atrial tumor involving the right superior pulmonary vein. The unique features are use of adjacent pericardium as an in situ patch to reconstruct the left atrium when there is no margin of left atrium remaining on the pulmonary veins and ...

The left tracheobronchial double-lumen tube is the commonest device to separate the left and right lungs for differential ventilation. With the appropriate tube, the left bronchial cuff is positioned in the bronchus so that the cuff is beyond the carina but the tip of the tube does not occlude the ...

Cardiac hydatid cysts are very rare in hydatid cyst disease. We report herein a case of hydatid cyst mimicking left atrial myxoma. A 78-year-old woman was admitted to our hospital with complaint of dyspnea and signs pulmonary edema and mitral stenosis. Echocardiography showed left atrial mobile, mostly solid mass with ...

RATIONALE: Cardiac biomarkers are used to distinguish acute dyspnea due to left-heart dysfunction from that of pulmonary origin. However, they have not been assessed in the specific setting of acute exacerbation of chronic obstructive pulmonary disease (AECOPD), where they might be released without left-heart impairment. OBJECTIVE: To assess the accuracy ...

The aim of this work was to study the handedness differences in the height of the right and left ethmoid roofs. Hand preference was assessed using the Edinburgh Handedness Inventory. The height of the right and left ethmoid roofs was measured with computerised tomography (CT). The incidence of persons who ...

Left Atrial Myxomas are notorious for their varied presentations. We describe one such case which initially presented with hemiparesis and seizures and was diagnosed as cerebral infarction and treated accordingly and decompression craniotomy with hinge flap was done for raised ICP and impending brain herniation. The main cause was a ...

A 62 year-old-woman presented with a right bundle branch block (RBBB) and left axis deviation (LAD) tachycardia. Radiofrequency (RF) energy was delivered to the left posterior fascicle (LPF) where 2 presystolic Purkinje potentials (P1 and P2) preceding onset of the QRS complex were recorded. During RF energy applications, the QRS ...

An 11-year-old Trakehner mare was presented with a firm moveable mass over the left maxilla. Radiography revealed a discrete opaque ovoid mass. Sialolithiasis of left parotid duct was diagnosed. The sialolith was excised by using a transoral approach and found to contain an organic nidus. The mare recovered without complications.

Cardiac myxoma is unusual and mostly located in left atrium. Although it is a benign tumor of the heart, it may cause life-threatening cardiac problems like valvular obstruction, systemic or pulmonary massive embolism, infection, arrhythmia, malignance. We report a huge cardiac myxoma originated from right atrium. It was moving between ...

The internal organs of animals often have left-right asymmetry. Although the formation of the anterior-posterior and dorsal-ventral axes in Drosophila is well understood, left-right asymmetry has not been extensively studied. Here we find that the handedness of the embryonic gut and the adult gut and testes is reversed (not randomized) ...

The purpose of the study was to evaluate the radiological anatomy of oblique fissures (OFs) on high-resolution computed tomography (HRCT) scans. We retrospectively reviewed HRCT scans of 144 patients with normal lung parenchyma. The uppermost level of OFs with respect to the ribs, configuration (concave, straight, convex and others), orientation ...

This editorial reviews the clinical presentation, electrocardiographic manifestations, appearance of the left ventricle by imaging techniques, and the state of the coronary arteries in four left ventricular apical abnormalities (Table I). Three of these conditions, namely, noncompaction, apical hypertrophy, and left ventricle aneurysm, can be somewhat malignant. The fourth condition--tako-tsubo--is ...

Cardiac myxomas are benign tumors of the heart with a surgical incidence of about 0.5/million population/year. They usually present during 4th to 6th decades and are more commonly seen in woman. About 75% arise in the Left Atrium (LA), most are single pedunculated, although multiple and villous forms have been ...

Luria (1947/1970) proposed left-top positions in arm folding (AF) and hand clasping (HC) to be signs of "latent left-handedness". However, research since has revealed that (1) left-top positions are canonical for European right-handers and (2) combined AF/HC measures may provide more information about cerebral laterality than either measure considered alone. ...

Myxoma is the most common tumor of the heart, with an estimated incidence of 0.5 to 1 per million per year. The majority of these tumors arise from the left atrium, and 20% arise from the right atrium with the remaining 5% arising in either the right or left ventricle. ...

Previous studies have shown that the left temporal polar (TP) region is important for the retrieval of proper names for persons. It has been proposed that the key specialization of left TP is for proper nouns (rather than names for persons, per se), which predicts that left TP should support ...

This presentation deals with a case of atrial flutter. During 2:1 A/V conduction, the QRS complexes showed a regular alternation of narrow beats and wide beats with a typical configuration of left bundle branch block. In contrast, pauses resulting from 4:1 A/V conduction ratio always resulted in narrow beats. Disappearance ...

The authors describe a patient who presented with a left sublingual swelling. Ultrasonic and sialographic investigation showed no salivary tissue in the expected left submandibular region, but a large salivary gland in the left floor of the mouth deep to the mylohyoid muscle. This is likely to represent an ectopically ...

In order to explore the microstructure of bilateral cingulum bundles associated with side and handedness, fractional anisotropy was extracted from diffusion tensor imaging. Distinguished from the conventional region of interest-based method, a fiber-based analysis method called scale-invariant parameterization method was employed to ascertain the anisotropy along the cingulum bundle in ...

To establish the vertebrate body plan, it is fundamental to create left-right asymmetry in the lateral-plate mesoderm to correctly position the organs. However, it is also crucial to maintain symmetry between the left and the right sides of the presomitic mesoderm, ensuring the allocation of symmetrical body structures, such as ...

Atrial myxomas are the most common primary tumors of the heart. Neurologic involvement usually occurs as a stroke with ischemic episodes. Following excision of cardiac myxomas, delayed neurologic events owing to aneurysms are rare and have not been reported from India. We report an operated case of left atrial myxoma. ...

The relationship between bilateral facial symmetry and beauty remains to be clarified. Here, straight head-on photographs of "beautiful" faces from the collections of professional modeling agencies were selected. First, beauty ratings were obtained for these faces. Then, the authors created symmetrical left-left and right-right composites of the beautiful faces and ...

We present eight adult patients with noncompaction (four with isolated left ventricular noncompaction and four with combined left and right ventricular noncompaction) in whom live three-dimensional transthoracic echocardiography (3D TTE) demonstrated multiple, prominent myocardial trabeculations, deep intertrabecular recesses communicating with the ventricular cavity, and a typical honeycombing appearance. In the ...

The diameter of the foramina varied between 0.4 mm and 1.6 mm. In most instances foramina were present between the lower ...

A 93-year-old woman with a history of hypertension was noted to have a mass in the left atrium prolapsing partially through the mitral valve on a routine surface echocardiogram in 2002. A transesophageal echocardiogram was then performed revealing an irregular mass with an appearance of protruding fronds of tissue. The ...

The case is reported of a 75 year old woman who presented with recurrent nocturnal episodes of acute pulmonary oedema. The cause was uncertain as she had normal cardiothoracic ratio on chest radiography and normal left ventricular systolic and diastolic function by transthoracic echocardiogram. Another transthoracic echocardiogram was repeated when ...

A 67-year-old patient, who had previously undergone Lucite ball plombage for pulmonary tuberculosis, presented with a hoarse voice, intermittent stridor and breathlessness. Direct laryngoscopy confirmed a left vocal fold palsy. A left supraclavicular mass became apparent and a computerized tomograph (CT) scan showed that a Lucite ball had migrated into ...

A 63-year-old man was admitted to our emergency department with the complaint of syncope. An electrocardiogram showed complete atrioventricular block with a low ventricular rate. He was hospitalized and a temporary transfemoral pacemaker was inserted under direct fluoroscopy urgently. Immediate postprocedural electrocardiogram in the paced mode showed right bundle branch ...

Atrial myxoma is the most common benign tumor of the heart. Patients who have atrial myoxmas usually present with cardiac obstruction, arrhythmias, or peripheral embolization. A tumor originating in the left atrium most often embolizes to the cerebrovascular system. Complete myxoma embolization to the peripheral vessels is rare and usually ...

Summary: A 22 year old female presented in 1987 a cardiac myxoma, removed in 1991. In 1992 catheter angiography showed bilateral aneurysms. Conservative treatment was elected. In 2000 recurrence of the myxoma and subsequent removal, prompted new angiography. All aneurysms had decreased in size, some had spontaneously disappeared.

The bicentenary of the birth of Rokitansky, the first true descriptive pathologist, was celebrated in February 2004. Rokitansky gathered many and important specimens that are now displayed in the Federal Museum of Pathological Anatomy in Vienna. On examining Rokitansky's collection we found a myxoma of the pulmonary valve of a ...

Most muscle originates from the myotomal compartment of the somites, paired structures flanking the neural tube. Whereas vertebrate embryos show molecular and morphological asymmetry about the left-right body axis, somitic myogenesis is thought to occur symmetrically. Here, we provide the first evidence that myotome pairs are transiently left-right asymmetric, with ...

Multiple myxomas in the ventricles, causing pulmonary obstruction, are extremely uncommon. We treated multiple myxomas, seemingly clinically malignant, which had caused acute right heart failure due to their position in the outlet of the right ventricle. The position of the myxomas obstructed the pulmonary artery. To prevent the right heart ...

Bundle branch reentrant tachycardia (BBRT) is an uncommon form of ventricular tachycardia involving diseased bundle branches. Phase IV bundle branch block also accompanies severe His-Purkinje disease. We present an unusual case of BBRT in a patient who also manifests a unique self-perpetuating cycle of AV block and phase IV left ...

We report the usefulness of live three-dimensional transthoracic echocardiography (3DTTE) in the morphological assessment of a left ventricular thrombus. Using live 3DTTE, the thrombus could be easily viewed end-on and from the sides. In addition, by cropping the 3D images sequentially in transverse (horizontal or short axis), longitudinal (vertical or ...

A pulsatile left ventricular assist device (LVAD) was used to support the aortic blood pumping function of an injured left ventricle, and as a result helped its recovery. It is important to observe a left ventricle's pumping status and to adjust the operating status of a LVAD to reduce the ...

Two experiments were conducted to examine how activation of the motivational systems of approach and withdrawal (arm flexion vs. extension) through 2 different bodily mechanisms (right arm vs. left arm) influenced participants' evaluations of neutral Chinese ideographs. Study 1 found that unilateral flexion on the right side and unilateral extension ...

Ureteral obstruction secondary to endometriosis is relatively uncommon. We present a 43-year-old multiparous woman who suffered from periodic left loin pain in the terminal period of her menstruation.

Width of craniofacial regions was assessed by computerized tomography. Handedness was associated with the left face width especially ...

The role of electrical heterogeneity in development of cardiac arrhythmias is well recognized. The extent to which transmembrane action potential (TAP) heterogeneity contributes to the normal electrophysiology of well-oxygenated atria is not well defined. The principal objective of the present study was to define regional and transmural differences in characteristics ...

The anesthetic of a patient who presented for vascular access under axillary block is described. After physical examination and ultrasound study, the patient was found to have a bifid axillary artery. Because of neurologic anomalies associated with this vascular variation, an interscalene block was chosen for the procedure. The clinical ...

INTRODUCTION: The occurrence of arrhythmias in adult patients may arise preferentially in anatomic regions derived from the specialized cardiac conduction system. To examine this hypothesis, we performed a detailed analysis of the developing cardiac conduction system using the recently described CCS-lacZ transgenic mouse strain. METHODS AND RESULTS: Transgenic embryos (E9.5-15.5) ...

Our purpose here is to describe our experience with important hemobilia following PTBD and to determine whether left-sided percutaneous transhepatic biliary drainage (PTBD) is associated with an increased incidence of important hemobilia compared to right-sided drainages. We reviewed 346 transhepatic biliary drainages over a four-year period and identified eight patients ...

Myxoma is the most common benign neoplasm of the heart. This work is the first to present an unusual left atrium and mitral valve cardiac myxoma which cannot be completely resected. This cardiac myxoma was also associated with abundant mucopolysaccharidic matrix, including mucin. Mucin gene expression is cell- and tissue-specific, ...

The purpose was to evaluate supine/left decubitus as an alternative to supine/prone scanning in computed tomographic colonography (CT colonography). Fifty patients were randomised to supine/prone, another 50 to supine/left decubitus scanning. Patients were scanned using a single-slice CT scanner. The colon was divided into eight segments. Comparisons of distension, breathing ...

BACKGROUND: The inability of volitional unilateral eyelid closure is an uncommon symptom of a central nervous system disorder. When it occurs as the result of a localized brain lesion, it is debated to be a form of supranuclear facial palsy or an apraxic phenomenon. OBJECTIVES: To report and discuss a ...

We evaluated the extent of agreement among three algorithms used for the localization of accessory pathways in patients with overt preexcitation. By the use of one algorithm, three independent couples of observers localized the accessory pathway in 95 consecutive patients showing overt preexcitation in the 12-lead surface electrocardiogram. We defined ...
