OBJECTIVE To determine the pulmonary venous flow velocity (PVFV) values in a large normal population. DESIGN Prospective study in consecutive individuals. SETTING University hospital. METHODS Among 404 normal individuals, the flow velocity pattern in the right upper pulmonary vein was recorded in 315 subjects using transthoracic echocardiography, and in both upper pulmonary veins in 100 s...

disproportion between the work done by the left heart and that done by the right." If the amount of blood drawn from the lungs through the pulmonary veins is less than that delivered to them through the pulmonary artery, then the condition of affairs in the pulmonary circulation is such as will cause this dangerous emergency. Welch's experimental work 011 rabbits showed that after compression o...

A Cypriot male of 22 years died after suffering recurrent daily haemoptyses of varying severity and slowly increasing effort intolerance for a period of four and a half years. Examination of a lung biopsy specimen revealed dilated vascular channels suggestive of a congenital anomaly of the pulmonary vasculature. Histological examination of the lung following necropsy revealed the diagnosis of p...

A new method has been described for measuring the pressure and resistance to blood flow in the pulmonary arteries, capillaries, and veins. Studies were performed in dog isolated lung lobes perfused at constant flow with blood from a donor dog. Pulmonary artery and vein volume and total lobar blood volume were measured by the ether plethysmograph and dyedilution techniques. The longitudinal dist...

endocarditis is rarely reported in sheep and information presented for ovine endocarditis is based mostly on comparative findings in the cattle. infective vegetative endocarditis of the right heart was diagnosed in a 3-year-old fat-tailed ram. clinical findings included tachycardia, marked brisket edema, jugular veins distention and pulsation and pale mucous membranes. hematologic abnormality i...

A 56-year-old man with locally advanced gastric carcinoma underwent echocardiography prior to commencing chemotherapy to assess the left ventricular systolic function. Echocardiography disclosed a severely dilated right heart, with preserved right ventricular systolic function and a normal predicted pulmonary artery systolic pressure. The inter-atrial septum was intact and no other structural c...

A 51-year-old woman was admitted to our hospital because of shortness of breath. Her mean pulmonary artery pressure was 52 mm Hg, and idiopathic pulmonary artery hypertension was diagnosed. She received beraprost sodium, imidapril, warfarin, and home-based oxygen therapy. At 67 years of age, dyspnea on effort worsened to New York Heart Association functional class III. The plasma level of brain...

Discussion Although anomalies of the inferior vena cava are commonly discovered during imaging for other diseases,'-3 it seems that the anomaly in this patient directly contributed to the pathogenesis of the haemoptysis. The bronchial venous system communicates freely with the pulmonary veins and alveolar capillaries on one side, and with the azygos vein on the other." A direct communication be...
