Left-to-Right Shunts
Contrary to the opinion of French pediatrician HenriLouis that isolated ventricular septal defects (VSDs) are universally well tolerated, the subsequent discoveries of Eisenmenger, Abbott, Wood, and others have taught us that the prognosis of left-to-right shunt lesions is not always benign. After more than a century of research, as pediatric cardiologists and congenital heart surgeons, we clai...
متن کاملThe prevalence of right to left shunt in chronic obstructive pulmonary disease patients with increased pulmonary hypertension
Background: One of the important etiologies for cryptogenic stroke is paradoxical embolization secondary to Patent Foramen Ovale (PFO). Foramen ovale can secondarily reopen due to Pulmonary Arterial Hypertension (PAH) which is common among the older age. PAH is known as a frequent and life threatening complication of COPD. The aim of this study was to determine the prevalence of PFO between COP...
متن کاملThe effects of surgical abolition of left-to-right shunts on the pulmonary vascular dynamics of patients with pulmonary hypertension.
AN IMPORTANT deficiency in our knowledge of congenital heart disease is the lack of detailed information concerning the effects of corrective surgery on the pulmonary vascular bed in patients with pulmonary hypertension. It is now well established that operation in such patients is associated with a substantially higher mortality and morbidity than in patients with similar anatomic lesions but ...
متن کاملThe Identification of Right-to-Left Shunts
SEVERAL METHODS are now used in conjunction with cardiac catheterization for localizing and quantitating right-to-left shunts. These include the recording of indicator-dye concentration curves after selective intracardiac dye injection,14 the external recording of radioactivity following injection of radioactive materials,5 6 and the use of cardioangiograms or cineangiograms to picture the cour...
متن کامل[Cardiovascular magnetic resonance evaluation of left-to-right shunts due to cardiac septal defects in patients with pulmonary arterial hypertension].
INTRODUCTION AND OBJECTIVES As cardiac septal defects are frequently associated with pulmonary arterial hypertension, hemodynamic assessment is essential before deciding on surgery. The aim of this study was to evaluate the use of cardiovascular magnetic resonance imaging for assessing cardiac shunts and for quantifying pulmonary artery systolic pressure in patients with cardiac septal defects....
