1/72. Clinical manifestation and survival of patients with idiopathic bilateral atrial dilatation.We studied the histories of eight patients who lacked clear evidence of cardiac abnormalities other than marked bilateral atrial dilatation and atrial fibrillation, which have rarely been discussed in the literature. From the time of their first visit to our hospital, the patients' chest radiographs and electrocardiograms showed markedly enlarged cardiac silhouettes and atrial fibrillation, respectively. Each patient's echocardiogram showed a marked bilateral atrial dilatation with almost normal wall motion of both ventricles. In one patient, inflammatory change was demonstrated by cardiac catheterization and endomyocardial biopsy from the right ventricle. Seven of our eight cases were elderly women. Over a long period after the diagnosis of cardiomegaly or arrhythmia, diuretics or digitalis offered good results in the treatment of edema and congestion in these patients. In view of the clinical courses included in the present study, we conclude that this disorder has a good prognosis.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/72. mycobacterium avium complex pleuritis accompanied by diabetes mellitus.A 72-year-old woman with diabetic nephropathy was hospitalized with peripheral edema in the extremities and weight increase. After diuretics and human serum albumin administration, her condition improved. From the 15th day she had run a subfever and her breathing was diminished in the left lower lung field. A plain chest x-ray film showed pleural effusion over the left lung field. The fluid was exudative. Fluid cultures were negative. A tuberculin reaction was negative. polymerase chain reaction method disclosed mycobacterium avium complex, indicating rare pleuritis due to mycobacterium avium complex. Eighteen days after chemotherapy, pleural effusion disappeared. Although her hemoglobin A1c (HbA1c) levels were maintained from 6.0 to 6.5% over 4 years, urinary albumin excretion levels and serum creatinine levels increased, indicating deteriorating diabetic nephropathy. serum albumin levels remained low (3.3-3.6 g/dl). malnutrition, impaired cellular immunity and apparently abnormal microvascular circulation due to diabetes mellitus may consequently have induced pleuritis due to mycobacterium avium complex.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
3/72. Pulmonary thrombosis, homocysteinemia, and reperfusion edema in an adolescent.Deep vein thrombosis, pulmonary embolism, and pulmonary thrombosis in situ are rare in childhood and adolescence [1,2]. Unfortunately, these diagnoses may be unsuspected in a pediatric patient with dyspnea and chest pain. This article illustrates the diagnostic and therapeutic challenges that arose from unrecognized chronic thrombotic disease in an adolescent.- - - - - - - - - - ranking = 2.6309348109848keywords = chest pain, chest (Clic here for more details about this article) |
4/72. Huge calcified aneurysm of the sinus of valsalva.Aneurysms of the sinus of valsalva often remain undiagnosed until they rupture. A 61-year-old man had a huge, heavily calcified unruptured aneurysm, originating from the right sinus of valsalva, detected incidentally on a chest radiograph taken for the diagnosis of cardiomegaly. Two-dimensional echocardiography revealed pericardial effusion with a huge calcified mass compressing the right ventricular outflow tract. The Doppler color-flow echocardiogram showed blood flow from the aortic root into the aneurysm. A chest computed tomographic scan revealed a large thrombosed aneurysm originating from the aortic root and measuring 10x10 cm. After pericardiocentesis, cardiac catheterization was performed, which showed that the right ventricular systolic pressure had elevated to 80 mmHg. Aortic root aortography demonstrated a huge unruptured calcified aneurysm in the sinus of valsalva arising from the right coronary sinus. The patient underwent surgical correction to prevent aneurysmal rupture and to relieve the right ventricular outflow obstruction.- - - - - - - - - - ranking = 2keywords = chest (Clic here for more details about this article) |
5/72. Congenitally unguarded tricuspid valve orifice with a giant right atrium and a massive clot in an asymptomatic adult.Congenitally unguarded tricuspid valve orifice, a variant of tricuspid valve dysplasia, is a rare malformation with protean manifestations. This report describes an asymptomatic adult who, on echocardiographic examination ordered in view of an abnormal 12-lead surface electrocardiogram and plain chest X-ray, was found to have an unguarded tricuspid valve orifice with a giant right atrium (12 x 10 cm), intense spontaneous echo contrast and a large right atrial clot.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
6/72. Asymptomatic giant right atrial aneurysm.A 5-year-old asymptomatic boy was found incidentally, on a chest radiograph, to have gross cardiomegaly; further evaluation by echocardiography showed a giant right atrial aneurysm. The patient underwent successful surgical reduction of the right atrium, closure of an atrial septal defect, and tricuspid valve repair These measures were taken to prevent thrombus formation in the right atrium, prevent paradoxical embolism, and lower the risk of atrial arrhythmias. The morphologic features of the resected atrial tissue showed paper-thin wall with a central aneurysm and focal endocardial fibrosis consistent with a diagnosis of idiopathic dilatation of the right atrium.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
7/72. Bilateral cystic adenomatoid lung malformation type III--a rare differential diagnosis of pulmonary hypertension in neonates.Congenital cystic adenomatoid lung malformation (CCAM) is a rare disorder characterized by replacement of normal pulmonary tissue with cysts of variable size and distribution. Only sporadic cases of CCAM type III have been described that were stillborn or died in the early neonatal period. To our best knowledge we report the first infant with bilateral CCAM type III that was not ventilator-dependent for the first 10 weeks of life and survived until the age of 5 months. Postnatally the newborn presented with signs of only mild respiratory distress and chest radiograph did not show evidence of cystic lesions. In the following weeks the major clinical symptom was persistent pulmonary hypertension with severe tachypnea, O2 requirement and CO2 retention. Pulmonary hypertension did not respond to HFOV ventilation, NO ventilation or prostacyclin inhalations. CONCLUSIONS: (1) Persistent pulmonary hypertension can be a major clinical feature in neonates with bilateral CCAM type III. (2) A normal chest X-ray does not exclude the possibility of bilateral type III CCAM. (3) Computerized tomography appears to be superior to conventional chest X-ray imaging in detection of small cystic lesions in infants with CCAM type III. (4) In cases of prenatally suspected CCAM type III, parents should be informed that short-term survival is possible.- - - - - - - - - - ranking = 3keywords = chest (Clic here for more details about this article) |
8/72. Intrapericardial teratoma in a twin with severe failure to thrive.We report on one affected twin who presented with cough, dyspnoea and severe failure to thrive. He was found to have gross cardiomegaly on chest X-ray. This proved to be due to an intrapericardial teratoma with an associated pericardial effusion. The operation on this rare tumour was successful.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
9/72. Cystic thymoma simulating contrictive pericarditis. The role of echocardiography in the differential diagnosis.A case is presented of a 60-year-old woman with fatigue, dyspnea, and chest pain. A chest x-ray film revealed an abnormal cardiac silhouette. echocardiography revealed a large, echo-free area with well-demarcated, discrete borders adjacent to the right heart border. This structure decreased in size with inspiration and did not show pulsatile cardiac motion. cardiac catheterization confirmed the extracardiac nature of the lesion and also showed a "constrictive" pattern with equalization of diastolic pressures. Surgical exploration revealed a large cystic thymoma. With removal of the tumor, intracardiac pressures returned to normal.- - - - - - - - - - ranking = 3.6309348109848keywords = chest pain, chest (Clic here for more details about this article) |
10/72. heart enlargement after thrombolysis for unsuccessful resuscitation.Thrombolysis has been recently reported for the treatment of unsuccessful out-of-hospital cardiopulmonary resuscitation. This case report presents the first case of mediastinal hematoma following thrombolysis in this setting. Chest X-ray and hemodynamic pattern mimicked pericardial effusion with cardiac-filling compromise. diagnosis was established by transesophageal echocardiography and chest computerized tomodensitometry.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
