Shunt Size in Atrial Septal Defect
Two-dimensional echocardiography and pulsed-Doppler studies have not proved to be reliable methods of assessing left-to-right shunt size in atrial septal defect. Doppler color-flow imaging displays the transatrial jet, providing a new dimension with the potential capability of quantifying left-to-right shunt size. Twenty-three patients with atrial septal defect were studied by color-flow imagin...
متن کاملIndicator dilution curves in atrial septal defect.
The indicator dilution technique has evolved into an invaluable method for the detection and localization of congenital and acquired cardiac shunts. The groundwork for much of the work in this field has been laid by Wood, Swan, and Helmholz (1957); Swan (1959); Hetzel, Swan, and Wood (1959); Braunwald, Tanenbaum, and Morrow (1958) and Braunwald and Morrow (1960). Indocyanine green is the most c...
متن کاملBidirectional shunt in uncomplicated atrial septal defect.
The presence of right to left shunts at atrial level in 40 patients with an uncomplicated atrial septal defect was determined by measuring the pulmonary vein to systemic artery oxygen stepdown . In six patients (group 1) a sizeable right to left shunt was found: left atrial oxygen stepdown was greater than or equal to 0.7 vol%, mean right to left shunt 0.67 1/min/m2 (range 0.36-1.0), and arteri...

متن کاملQuantitative, non-invasive assessment of ventricular septal defect shunt flow by measuring proximal isovelocity surface area on colour Doppler mapping.
OBJECTIVE To determine whether the proximal isovelocity surface area (PISA) method could be applied to estimate the magnitude of ventricular septal defect (VSD) shunt flow. DESIGN Prospective analysis of clinical, echocardiographic, and angiographic data. SETTING University hospital. PATIENTS 14 children with VSD. METHODS Colour Doppler images of VSD shunt flow were obtained in paraster...
