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 congenital pulmonary lesions may be diagnosed through ultrasonographic screenings or be revealed as causes of respiratory distress in the neonatal period and infancy. less commonly, they are detected as incidental features. objectives our study represents the diversity of congenital pulmonary lesions and their characteristics during an 11-year period in a referral teaching children’s...

pulmonary hypertension is rare but is one of the complications that occur due to hiv infection. symptoms of hiv-associated pulmonary arterial hypertension are often non-specific but the main symptom of the disease is dyspnea. in this cross-sectional study, we measured systolic pulmonary arterial pressure (spap) by echocardiographic methods among hiv-positive patients who received art. this rese...

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...

hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...

although dental foci can be sources of bacteremia and bacterial endocarditis, hematogenous spread of infection presented with septic pulmonary embolism apparently is rare. the occurrence of septic pulmonary embolism in patients with periodontal disease without suppurative thrombophlebitis of the great vessels of the neck is well documented but to our knowledge, there is no report on septic pulm...
