Negative contrast echocardiography: a new method for detecting left-to-right shunts.
Cross-sectional echocardiographic visualization of the interatrial septum in both normal persons and patients with atrial septal defects has been reported. Although septal defects can generally be visualized, false positives are frequently encountered. This study evaluated whether visualizing the patterns of contrast flow in the region of an apparent atrial septal defect by cross-sectional echo...
متن کاملPulmonary shunt fraction measurement compared to contrast echocardiography in hereditary haemorrhagic telangiectasia patients: time to abandon the 100% oxygen method?
BACKGROUND The presence of pulmonary right-to-left shunting (RLS) is associated with severe neurological complications from paradoxical embolisation in patients with hereditary haemorrhagic telangiectasia (HHT) and screening is warranted. Pulmonary shunt fraction measurement with the 100% oxygen method can be used for the detection and quantification of functional pulmonary RLS, although transt...
متن کاملLeft-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 کاملReproducibility of right-to-left shunt quantification using transthoracic contrast echocardiography in hereditary haemorrhagic telangiectasia
AIM Transthoracic contrast echocardiography (TTCE) is recommended for screening of pulmonary arteriovenous malformations (PAVMs) in hereditary haemorrhagic telangiectasia. Shunt quantification is used to find treatable PAVMs. So far, there has been no study investigating the reproducibility of this diagnostic test. Therefore, this study aimed to describe inter-observer and inter-injection varia...
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...
