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....

INTRODUCTION AND OBJECTIVES The reported incidences of stenosis after radiofrequency ablation of pulmonary veins are highly variable. Moreover, most studies have focused on severe stenosis and have overlooked mild stenosis. Our aims were to study postablation morphological changes in the pulmonary veins and to evaluate preablation magnetic resonance imaging predictors for stenosis. METHODS Ei...

The average pulmonary blood volume in normal persons was 211 ml./m.2, in patients with mitral regurgitation 266 mnl./m2, and in those with mitral stenosis 419 ml./m.2 In patients with mitral stenosis the pulmonary blood volume could be related to pulmonary symptoms like exertional dyspnoea, haemoptysis, and paroxysmal nocturnal dyspnoea. Pulmonary blood volume could also be related directly to ...

After having undergone surgical correction at an early age, many patients with tetralogy of Fallot develop long-term complications including progressive pulmonary regurgitation and peripheral pulmonary stenosis. A high percentage of these patients need to undergo a second operation in their adolescence or early adulthood. If simultaneous treatment of both pulmonary regurgitation and peripheral ...

Flash pulmonary edema frequently develop in case of bilateral renal artery stenosis and unilateral renal artery stenosis with functional solitary kidney. In some rare cases, unilateral renal artery stenosis with bilaterally functional kidneys may also lead to flash pulmonary edema. Here, we present a case of flash pulmonary edema caused by accessory renal artery stenosis. To our knowledge, it i...

OBJECTIVE Currently, no quantitative guidelines have been established for treatment of left pulmonary artery (LPA) stenosis. This study aims to quantify the effects of LPA stenosis on postoperative hemodynamics for single-ventricle patients undergoing stage II superior cavopulmonary connection (SCPC) surgery, using a multiscale computational approach. METHODS Image data from 6 patients were s...

INTRODUCTION Pulmonary stenosis remains the most frequent complication and cause of reintervention after the arterial switch operation for transposition of the great arteries We investigated the onset, incidence, and outcome of pulmonary stenosis after arterial switch operation in neonates with transposition of the great arteries and intact ventricular septum. METHODS Arterial switch operatio...
