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...

A 34-year-old Puerto Rican w-as admitted to Lincoln Hospital February 10, 1956, complaining of chest pains, vomiting, marked dyspnea, and ankle edema.

متن کاملA Systematic Review of Acquired Left Ventricle to Right Atrium Shunts (Gerbode Defects).
T he left ventricle-right atrium (LVRA) shunt, a rare and special type of ventricular septal defect (VSD), was first reported by Gerbode et al1 in 1958, and was thus termed “Gerbode defect”, after the first author. In 1967, Riemenschneider and Moss2 classified Gerbode defects into two types: direct (or true) and indirect (or false). The direct type is a direct shunt between the left ventricle a...
متن کاملBuilding the right ventricle.
Abnormal development of the arterial pole of the heart underlies a significant fraction of congenital heart defects. Critical steps in arterial pole development are formation of the myocardial outflow tract (or conotruncal region) and its subsequent division into separate left and right ventricular outlets. Division of the cylindrical outflow tract is a complex morphogenetic process driven by c...
متن کاملLeft Ventricle: Role of the Pericardium and the Right Ventricle
IN CHRONIC CARDIAC DISEASE, the left ventricular diastolic pressure does not provide a reliable guide to the diastolic left ventricular volume,' and measurement of chamber volume, shape and wall thickness are necessary to identify changes in the myocardial stress-strain relation.' Under acute conditions, the stiffness of the left ventricular chamber progressively increases as passive diastolic ...
