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 کاملLeft-to-right shunts in control of bleeding following surgery for aneurysms of the ascending aorta.
Surgical repair of complex thoracic aneurysms requiring aortic valve replacement and coronary revascularization is occasionally complicated by significant bleeding despite the experience of the surgeon. While bleeding from the mediastinal tissues and the anterior suture line is usually easily controlled, posterior bleeding may require dismantling the repair and a second bypass run. The synergis...
متن کاملCardiovascular abnormalities following surgery for left-to-right shunts. Observations in atrial septal defects, ventricular septal defects, and patent ductus arteriosus.
SUMMARY Seventy-two patients with left-to-right shunts were studied an average of 5 years after operation. Persistent residual shunts occurred in 24 of the 72 patients and were unsuspected clinically in 11. While significant residual shunts were usually suspected in the group with ventricular septal defects (VSD), residual shunts in the group with atrial septal defects (ASD) were frequently uns...
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 کاملHyperventilation test for diagnosis of left-to-right circulatory shunts.
Pulmonary and systemic arterial carbon dioxide tensions (Pco2) were measured at cardiac catheterization in I.f patients with left-to-right circulatory shunts and in irS patients with valvular heart disease. The measurements were performed under resting conditions and at 5-sec intervals during a 30-sec period of hyperventilation. In both groups the systemic arterial Pco2 fell significantly durin...
