1/93. T wave lability: a clue for separating the good from the bad, when ugly.Non-specific T wave abnormalities have challenged both the clinician and the insurance medical director for decades. Distinction between pathologic and physiologic T wave changes often requires costly and time-consuming diagnostic studies. The literature is reviewed on the subject of T wave manipulation by the oral administration of both potassium and glucose, introducing the concept of T wave lability. Based on this concept, a simple technique is suggested which, in many cases, can safely, expeditiously and inexpensively distinguish between organic and functional T wave changes. When employed in the investigation of asymptomatic insurance applicants with unexplained T wave abnormalities but no known cardiovascular or renal disease, this technique appears to be sufficiently reliable to classify the risk posed by non-specific T wave changes without resorting to a sophisticated, lengthy and costly cardiovascular investigation.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/93. phrenic nerve injury following cardiac surgery: a review.phrenic nerve injury following cardiac surgery is variable in its incidence depending on the diligence with which it is sought. Definitive studies have shown this complication to be related to cold-induced injury during myocardial protection strategies and possibly to mechanical injury during internal mammary artery harvesting. The consequences are also variable and depend to a large extent on the underlying condition of the patient, particularly with regard to pulmonary function. The response of the patient may range from an asymptomatic radiographic abnormality to severe pulmonary dysfunction requiring prolonged mechanical ventilation and other associated morbidities and even mortality. Two cases are presented to demonstrate the variability in clinical responses to diaphragmatic dysfunction secondary to phrenic nerve injury from cardiac surgery. In addition, treatment strategies are reviewed including early tracheostomy and diaphragmatic plication, which appear to be the most effective options for patients who are compromised by phrenic injuries.- - - - - - - - - - ranking = 0.24658405660447keywords = nerve (Clic here for more details about this article) |
3/93. A comprehensive analysis of the fluid and electrolytes system. An interactive exercise.The fluid and electrolyte system is difficult to study because one cannot examine an organ in order to understand the anatomical and functional connection. This exercise was developed to emphasize the connection between different fluid and electrolyte situations.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
4/93. Intrapericardial organized hematoma. A rare complication after open heart surgery.Intrapericardial organized hematoma, which compresses cardiac chambers late after open heart surgery, is extremely rare. We report a case of intrapericardial organized hematoma in a 63-year-old man who underwent aortic valve replacement 8 years prior, which may have aggravated rheumatic mitral valve regurgitation compressing the mitral valve anulus. Under extracardiopulmonary bypass and cardioplegic heart arrest, we removed the hematoma and replaced the mitral valve with a 27 mm St. Jude Medical valve. There were no bleeding points on the heart and pericardium at operation and no history of blunt chest trauma. The etiology of the hematoma is uncertain.- - - - - - - - - - ranking = 6keywords = organ (Clic here for more details about this article) |
5/93. Polyvisceral echinococcosis with involvement of the heart and chest wall: follow-up and review of literature.echinococcosis remains an endemic surgical problem in countries where sheep and cattle raising is carried out, particularly in many Mediterranean countries. The life cycle of echinococcosis is usually marked by the filtration of larvae through the liver and lungs which are the organs most commonly affected by a hydatid cyst. Hydatid cysts in other sites are not common. Cardiac echinococcosis has been reported infrequently even in countries in which hydatid disease is endemic, only isolated sporadic cases have been reported in the literature. Here we report a case of polyvisceral hydatid cyst with involvement of heart and chest wall and reviewed the literature and discussed clinical procedures and management.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
6/93. Cardiac involvement and left ventricular failure in a patient with the churg-strauss syndrome.The churg-strauss syndrome is characterised by a history of asthma and paranasal sinus disease, eosinophilia of more than 10 per cent, non-fixed pulmonary infiltrates on chest radiography and vasculitis which may affect multiple organ systems. The condition usually manifests in the 4th decade. We present a 21-year old female with a history of asthma since one year of age who developed symptoms and signs of pneumonia, a pulmonary infiltrate on chest radiography and eosinophilia. This was followed a few weeks later by vasculitis which affected the skin and myocardium and associated with a peripheral eosinophilia of more than 80%. physical examination revealed palpable purpura and signs of left ventricular failure. echocardiography confirmed significant diminution of left ventricular contractility. A rapid improvement was observed after steroid therapy. echocardiography after two months showed normal left ventricular function. In this presentation we review the cardiac manifestations of the churg-strauss syndrome and its management.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
7/93. Mobile right atrial hydatid cyst with multiorgan involvement.A 25-year-old woman who had hydatid cysts in her lung was referred to our clinic for the hydatid cyst in her cardiac localization. Multiple hydatid cysts of different cardiac localizations were diagnosed by two-dimensional echocardiography, confirmed by computed tomography and magnetic resonance imaging, supported by enzyme-linked immunosorbent assay (ELISA) for echinococcosis. Surgical resection was performed for the right atrial cyst and pathology confirmed the diagnosis. Oral albendazole treatment was given postoperatively. Cathet. Cardiovasc.

8/93. Rapid recurrence of an inflammatory myofibroblastic tumor in the right ventricular outflow tract.We describe an unusual case of rapid recurrence of a previously excised inflammatory myofibroblastic tumor of the right ventricular outflow tract in a 5-month-old infant. The infant is asymptomatic 18 months after the second surgery. The very rare cardiac involvement, and the early relapse of the inflammatory pseudotumor, to the best of our knowledge, is a unique combination. The inflammatory myofibroblastic tumor, as known as a pseudotumor or plasma cell granuloma is an uncommon reactive lesion with unknown aetiology. It is found most commonly in the lung and a number of visceral organs, such as the spleen, liver, ileum, salivary glands, urinary bladder, larynx or brain or in the retroperitoneum and lymph nodes. To our knowledge only 9 cases have been published of such tumor arising within the heart.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |

10/93. phenotype of a patient with pure partial trisomy 2p(p23-->pter).We present the case of a 7-month-old girl with the karyotype 46,XX, der(13) t(2;13)(p23;p11.2).ish der(13)(wcp2 ) de novo. Painting confirmed that the additional segment on 13p was of chromosome 2 origin, resulting in trisomy 2p23 -->2pter. The child had a prominent forehead with a flat hemangioma, depressed nasal bridge, protruding tongue, posteriorly angulated ears, esotropia with poor abduction of the right eye, bilateral severe myopia (-5.5 D), retinal hypopigmentation, foveal hypoplasia, and striking left optic nerve hypoplasia. She also had pectus excavatum, a protruding abdomen with diastasis recti, generalized hypotonia, delayed fine and gross motor development, grade II reflux on the left side, and grade III-IV reflux on the right side. An EEG showed epileptiform discharges. Computed tomographic scan of the brain showed decreased white matter, but magnetic resonance imaging showed normal results.- - - - - - - - - - ranking = 0.041097342767412keywords = nerve (Clic here for more details about this article) |
