Introduction:  In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...

background: actinomycosis is an indolent, slowly progressive infection caused by non acid fast, gram positive, anaerobic or microaerophilic bacteria. the most common site of actinomycosis infection is cervicofacial region. bacteriologic identification from infected site or detection of sulfur granules confirms the diagnosis. we report a rare case of simultaneous infection of larynx and lungs ac...

conclusions the etiology of pah in thalassemia is multifactorial such as inflammatory mediators. also, the absence of the spleen plays an important role in developing a high trv and pah. results average age of the patients was 21.15 ± 6.68 years. no significant difference was observed in the pap between the 2 groups of thalassemia major and intermedia and also the 2 sex groups. indeed, 6.6% of ...

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

pulmonary agenesis is a very rare condition and many of them are associated with a variety of cardiac and non-cardiac malformations. we report an eight-month old girl with chronic lung infection due to right sided pulmonary agenesis without any associated major cardiac or non-cardiac abnormalities. the case brings in forth the importance of investigating any infant presenting with features of c...

conclusion there is still excessive unjustified concern of pte in less trained physicians leading to excessive diagnostic work-up. loyalty to the existing guideline for management of suspected pte in educational hospitals and supervision of attending physicians could prevent overuse of ctpa. results during a 6-month period, 82 patients who underwent ctpa were included. the prevalence of pte was...

magnesium is an essential metal that has important roles in physiological function of the body organs. ethambutol is an oral antitubercular agent with chelating effects owing to its chemical structure. the aim of present study is to determine whether ethambutol usage can alter serum magnesium concentration in patients with pulmonary tuberculosis. sixty patients with diagnosis of pulmonary tuber...

background: determining the clinical significance of cardiac murmurs is widely considered in equine practice. pulmonary murmurs are commonly detected in athletic horses. echocardiography plays a leading role in assessment of these murmurs. objectives: echocardiographic evaluation of horses with pulmonary regurgitation and determining the importance of pulmonary valve murmurs. methods: a total n...
