Stenosis of individual pulmonary veins

Congenital stenosis of individual pulmonary veins.

CONGENITAL STENOSIS of individual pulmonary veins as they join the left atrium is a rare cause of pulmonary venous and arterial hypertension. Cases have been reported by Reye,1 Ferencz and Dammann,2 Andrews,3 Bernstein and associates,4 and Edwards.5' 6 Emslie-Smith and associates7 reported a patient with membranous occlusion of the pulmonary veins associated with pulmonary hypertension. The pur...

How to image individual pulmonary veins with transthoracic echocardiography

Although Doppler analysis of pulmonary veins (PVs) is crucial in the assessment of cardiac hemodynamics, there is controversy regarding individual anatomical PV imaging with transthoracic echocardiography (TTE). This report is a discussion of how to image PVs accurately using TTE. To resolve any contradiction, multiple TTE images were obtained during the selective catheterization of the PV in p...

Stenosis of pulmonary veins with ventricular septal defect. A cause of premature pulmonary hypertension in infancy.

Pulmonary vein stenosis is recognised as a rare, silent cause of pulmonary hypertension. ' The condition can occur with or without intracardiac anomalies. '3 The presence of lesions, such as ventricular septal defect, which cause pulmonary hypertension in their own right, can make suspicion of associated pulmonary venous obstruction difficult. In only one of the four reported cases4-7 of ventri...

[Bilateral pulmonary veins atresia].

Rev Esp Cardiol 2002;55(6):671-2 671 Congenital atresia of the pulmonary veins is a rare anomaly that is not associated with other heart disease. It has a poor prognosis and patients die secondary to pulmonary hypertension, recurrent hemoptysis, pulmonary edema, or congestive cardiac insufficiency. We present a 5-year-old male patient admitted to the hospital for asthenia, anorexia, hemoptoic v...
