Dilatation of the pulmonary artery occurs frequently in cases of valvular pulmonary stenosis and is often called "poststenotic." We determined the diameter of the pulmonary artery angiocardio-graphically and compared this with the data obtained by heart catheterization in cases of pulmonary stenosis and of idiopathic dilatation of the pulmonary artery. Features are presented which constitute ar...

The diagnosis of primary pulmonary vein stenosis is often overlooked because its symptoms overlap lung diseases and pulmonary arterial hypertension. Its diagnosis may be difficult because the condition is progressive and associated with other defects. We present a case of pulmonary vein stenosis in a newborn with stenosis of the left-sided common pulmonary vein, diffuse hypoplasia of the superi...

Pulmonary hypertension frequently complicates mitral stenosis. Increased pulmonary artery pressure results from raised left atrial pressure, pulmonary arteriolar constriction, and obliterative changes in the pulmonary vascular bed, and usually responds to surgical relief of mitral stenosis. However, severe pulmonary hypertension may persist after surgical treatment of mitral stenosis. We descri...

OBJECTIVE To evaluate the cardiovascular findings and clinical follow-up of patients with Williams-Beuren syndrome. METHODS We studied 20 patients (11 males, mean age at diagnosis: 5.9 years old), assessed for cardiovascular abnormalities with electrocardiography and Doppler echocardiography. Fluorescence in situ hybridization (FISH) was used to confirm the diagnosis of the syndrome. RESULT...

This report describes 3 cases of pulmonary stenosis in the recipient twin in twin-twin transfusion syndrome. Fetal echocardiography showed cardiomegaly, tricuspid valve regurgitation, and increased reverse flow in the inferior vena cava, as signs of congestive heart failure in all 3 cases. We diagnosed 2 cases of pulmonary stenosis by fetal echocardiography prenatally and confirmed our findings...

BACKGROUND Congenital pulmonary valve stenosis and patent ductus arteriosus are common congenital heart defects in dogs. However, concurrence of atypical pulmonary valve stenosis and patent ductus arteriosus is uncommon. This report describes the anatomic, histopathologic, and echocardiographic features in a dog with concomitant pulmonary valve stenosis and patent ductus arteriosus with atypica...

patients and methods ninety-eight children with congenital ps referred to affiliated hospital of jining medical college were recruited from october 2013 to march 2015. participants were divided into four groups according to different ages (0 - 1, 1 - 3, 3 - 7, 7 - 14), or three groups according to different heart rates (< 90, 90 - 110, > 110). image quality of pulmonary valves was assessed base...

Pulmonary vein stenosis is a recently described complication of radiofrequency ablation. We report a patient who experienced thrombosis of the lingular vein and pulmonary infarction resulting from mild single-vessel pulmonary vein stenosis. This report extends available experience with complications of radiofrequency ablation, by demonstrating pulmonary venous thrombosis as a complication of re...

Abstract Background Pulmonary hemosiderosis is a rare disease that may be idiopathic or have secondary etiology, such as mitral stenosis. The clinical and functional consequence of iron overload in the lungs form hemosiderin. diagnosis should considered patients with miliary nodules on chest tomography. Case presentation We report case 30-year-old man severe stenosis who presented pain dyspnea....
