an elevated pulmonary artery pressure (pap) from any cause is associated with increased mortality, especially in cases of primary pulmonary arterial hypertension (pah). one of the many reasons behind a bad prognosis is the inherent difficulty in assessing right ventricular (rv) function with reproducible methods. intensive research involving the left heart has made it relatively easy to assess ...

pulmonary arterial hypertension (pah) is a progressive disease with high morbidity and mortality rates. research has shown that pah has a prevalence rate of 10-79% in thalassemia major patients. this cross-sectional study was carried out in 2014 to determine the prevalence and risk factors of pah in all thalassemia major patients of over 18 years of age in ilam, iran. a cardiologist measured sy...

patients with pulmonary cavities are usually exposed to other pulmonary infections, especially of fungus origin, such as asnprgillosis and coccidiomycosis. they are manifested by the formation of fungus ball in these cavities, which is completely resistant to anti-fungal therapy. in these circumstance the best method of treatment is removing of the ball by surgery, in this paper a case of pulmo...

Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...

    Background: Since pulmonary angiography is the only non-invasive method for diagnosing pulmonary embolism, the use of radiation reduction methods without affecting the quality of images seems necessary. One of the simplest reasons for unnecessarily increasing of patient exposure is repetitive imaging due to poor image quality. Therefore, it is necessary to identify and ...

The six-minute walk test (6MWT) is a well-tolerated test which reflects daily activities and can be easily used in clinical practice. The 6MWT provides information about functional capacity, response to therapy and prognosis across a range of chronic cardiopulmonary conditions. Moreover, the 6MWT is sensitive to the common therapies used for chronic obstructive pulmonary disease, such as pulmon...

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...
