Echocardiographic detection of intracardiac right-to-left shunts following peripheral vein injections.
نویسندگان
چکیده
A contrast echocardiographic technique using peripheral vein injections for the detection and localization of intracardiac right-to-left shunting is described. Fifty children underwent cardiac catheterization and peripheral contrast echocardiographic studies. The site, degree, and direction of shunting were established at catheterization by oximetry, indicator dilution analysis and/or angiography. Peripheral vein injections were performed from the right antecubital vein or the right saphenous vein. Right-to-left shunts were documented at catheterization in 27/50 patients; contrast echocardiographic studies indicated the presence and level of shunting in all 27 patients. The contrast echocardiographic technique using peripheral vein injections detects and localizes right-to-left intracardiac shunting. It is a safe and sensitive method to evaluate systemic desaturation in ambulatory and postoperative patients.

Intracardiac right-to-left shunts demonstrated by two-dimensional echocardiography after peripheral vein injection.
venous injections ofdextrose 5 per cent in water, for the detection and localisation of atrial and ventricular right-to-left shunts was evaluated in 70 adult patients. Based on their catheterisation data, 20 patients had a shunt at atrial level (group 1) and 14 patients a ventricular septal defect (group 2). Thirty-six patients without a shunt by oximetry served as controls. Echo contrast could...

متن کاملRecognition of residual postoperative shunts by contrast echocardiographic techniques.
A bedside echocardiographic technique was used to detect and localize residual intracardiac shunts in 26 patients who had surgical repair of septal defects. Contrast echocardiography was performed through central venous and left atrial monitoring catheters at the same time as cardiogreen dye curves. Indicator dilution confirmed residual atrial defects in ten patients and ventricular defects in ...

OBJECTIVES The purpose of this study was to understand the reason for variation in the sensitivity of different methods of detecting right-to-left shunts (RLS). BACKGROUND Patent foramen ovale (PFO) is implicated in the pathogenesis of cryptogenic stroke, decompression illness, and migraine headaches. Intravenous agitated saline injections with tomographic imaging (transthoracic, transesophag...

A patient with hypoplastic left heart syndrome was studied using contrast echocardiography after peripheral venous injection of dextrose. The combination of the parasternal and suprasternal approach allowed for identification of the right ventricular cavity, excluded the presence of right-to-left intracardiac shunts, and established normal ventriculoarterial connections. From the abdominal appr...
