Contrast 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...

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...

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...

Perflutren-based echocardiographic contrast in patients with right-to-left intracardiac shunts.

septum length, and rims and thickness with electronic caliper edgeto-edge (4). Four main features were used to analyze patients: 1) diameter of the fossa ovalis (FO); 2) presence and length of the channel; 3) presence and degree of atrial septal aneurysm (ASA), following the classification of Olivares et al. (5); and 4) rim thickness. We also analyzed the presence of Eustachian valve and Chiari...

Atrial level right to left intracardiac shunt associated with postoperative hypoxemia: demonstration with contrast two-dimensional echocardiography.

Transient hypoxemia is not uncommon after major cardiac or thoracic surgery. The differential diagnosis includes atelectasis, pulmonary embolus, pneumonitis, congestive heart failure and several other diverse cardiovascular and pulmonary problems. Less well recognized is transient right to left intracardiac shunting through a patient foramen ovale or previously unsuspected atrial septal defect....
