conclusions in light of our findings, we concluded that ra function is severely diminished in adult patients with tof. it would play an important role in pathophysiological process of the right sided heart failure in these patients. results the myocardial velocities and deformational indices of ra free wall were significantly compromised in tof patients compared with normal subjects. there was ...
Background: Asthma is a predisposing factor for the development of atrial fibrillation. Asthma disturbs the electrophysiology in the right and left atrium. The aim of this study was to evaluate atrial electromechanical delay by coupling obtained from tissue Doppler imaging (TDI) in children. Methods: A cross-sectional study was conducted on 50 patients with Bronchial Asthma, compared with 50 hea...
A case of right atrial myxoma in a 5 year old male is presented. The Patient was admitted in the pediatric department with systemic manifestations. Myxoma was incidentally diagnosed.
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
Pulmonary artery pressure can be estimated from right ventricular-right atrial pressure gradient in patients with tricuspid regurgitation. The most common approach is to estimate pulmonary artery systolic pressure from right ventricular pressure (assuming no pulmonic stenosis) determined as the sum of the right ventricular-right atrial pressure gradient and either an assumed or clinically deter...
hydatid disease is a rare parasitic disease, which mainly involves liver then lung tissues. cardiac involvement is very rare, especially when there is not hepatic involvement. we describe a 47-year-old woman with a history of a lung hydatid cyst who was referred to rajaei heart center, tehran, iran in 2012. her chest computed tomographic scan showed a cardiac mass. echocardiographic examination...
introduction the eustachian valve (ev) remnant, when present in adults, is usually rudimentary. however, in echocardiographic examinations, it may appear as a mobile long structure in the right atrium, and it rarely protrudes into the right ventricle. when it is quite large, the ev remnant could be misdiagnosed as a right atrial tumor, thrombus, or vegetation. case presentation an 83-year-old p...
introduction left atrial thrombi are present in one third of patients with severe rheumatic mitral stenosis and atrial fibrillation. a left atrial mass can be diagnosed as a thrombus by transthoracic echocardiography in the presence of the predisposing factors for a thrombus such as mitral stenosis and atrial fibrillation. the sensitivity of transthoracic echocardiography for detecting left atr...
