[Low sensitivity of the echocardiograph compared with contrast transcranial Doppler in right-to-left shunt].
BACKGROUND Contrast transcranial Doppler (c-TCD) has a high sensitivity for detecting right-to-left shunt (RLS), and is probably higher than transthoracic echocardiography (TTE) and comparable with transesophageal echocardiography (TEE). OBJECTIVE To evaluate the accuracy of echocardiography (TTE and TEE) to detect RLS compared to c-TCD. MATERIAL AND METHODS Observational study of patients ...
متن کاملContrast transcranial Doppler compared to transesophageal echocardiography in detection of right-to-left shunt.
OBJECTIVE To assess contrast transcranial Doppler (TCD) for detection of right-to-left shunt (RLSh). METHODS We studied 30 patients aged between 25-45 years admitted to Al-Zahra Hospital, affiliated to Isfahan University of Medical Sciences, between May 2003 and May 2005. All patients underwent transesophageal echocardiography (TEE) with contrast and contrast TCD. RESULTS Eleven (36.6%) pat...
متن کاملSensitivity of transcranial Doppler versus intracardiac echocardiography in the detection of right-to-left shunt.
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...
متن کاملEffects of posture on right-to-left shunt detection by contrast transcranial doppler.
BACKGROUND AND PURPOSE There is controversy about the optimal patient position for the detection of right-to-left shunt (RLS). The study was performed to investigate which patient position best detects RLS during contrast-enhanced transcranial Doppler. METHODS We prospectively evaluated consecutive patients with ischemic stroke or TIA referred to our Noninvasive Cerebrovascular Laboratory for...
متن کاملComparison of High and Low Doses of Captopril in the Treatment of Neonates with Left-to-Right Shunt
Introduction: Due to the significant differences between the physiology and pathology of adults and neonates, clinical guidelines for adults are not directly applicable to children. This study was performed to evaluate the effects of high- and low- dose captopril on the neonates with large left-to-right shunts. Methods: The study was conducted on 20 neonates with congenital heart disease, left-...
