Although mild increase in pulmonary vascular resistance following intracardiac repair of tetralogy of Fallot is often seen in the early postoperative period, it usually subsides without any sequel. Persistent severe pulmonary artery hypertension after total correction is rare. We report a child with tetralogy of Fallot and Down's syndrome, who developed severe pulmonary hypertension and low car...

a2-year-old cachectic cross-breed gelding was admitted toveterinary teaching hospital of university of tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. therespiratory and heart rates were 35/min and 60 bpm, respectively.agrade iii/iv pansystolic murmur...

Chronic thromboembolic pulmonary hypertension (CTEPH) is the end result of persistent obstruction of the pulmonary arteries following episodes of acute and/or recurrent pulmonary emboli [1]. Pulmonary hypertension probably stems from a smaller pulmonary arterial cross sectional area due to thrombus organisation and a redistribution of blood flow through the patent pulmonary arterial bed produci...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening disease due to pulmonary artery obstruction by persistent organised clots related to one or more episodes of acute pulmonary embolism. To date, the pathogenesis of CTEPH remains unexplained. Pulmonary endarterectomy removes obstruction from pulmonary vessels and can cure patients. However, some unreachable distal pulmon...

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but life-threatening condition resulting from unresolved thromboembolic obstructions. Pulmonary endarterectomy surgery is currently the standard of treatment, as it is potentially curative; however, not all cases are amenable to surgical intervention due to distal distribution of the organized thromboembolic material or the presenc...
