Transthoracic echocardiography using second harmonic imaging with Valsalva manoeuvre for the detection of right to left shunts.
AIMS To assess transthoracic echocardiography (TTE) using second harmonic imaging with Valsalva manoeuvre compared to transesophageal echocardiography (TEE) for the diagnosis of right to left cardiac and pulmonary shunts. METHODS AND RESULTS One hundred and ten patients referred for TEE underwent TTE with bubble contrast. Bubbles in the left atrium within three cardiac cycles were considered ...
متن کاملComparison of transthoracic echocardiography using second harmonic imaging, transcranial Doppler and transesophageal echocardiography for the detection of patent foramen ovale in stroke patients.
AIMS The comparison of three imaging methods to determine which is the most accurate and reliable for the detection of right-to-left shunt. METHODS AND RESULTS One hundred and seven patients who were hospitalized for stroke underwent: a transthoracic echocardiography (TTE) using second harmonic, a transcranial Doppler (TCD) and a transesophageal echocardiography (TEE) from August 2003 to Apri...
متن کاملTransthoracic second harmonic two- and three-dimensional echocardiography for detection of patent foramen ovale.
AIMS Transoesophageal echocardiography (TEE) with contrast administration is still considered as the reference method for the detection of patent foramen ovale (PFO) with interatrial shunt, but it is a semi-invasive exam. The aim of the present study is to evaluate a role of two- and three-dimensional transthoracic echocardiography (TTE and R3DTE) as a diagnostic alternative to transcranial Dop...
متن کاملSecond harmonic transthoracic echocardiography: the new reference screening method for the detection of patent foramen ovale.
AIM Transesophageal echocardiography (TEE) is still considered as the reference method for the non-invasive detection of right-to-left shunts. Echocardiographic laboratories are spending most of their time performing TEE studies to exclude a thromboembolic cardiac disease. In a considerable proportion of these patients the question can be simplified to exclude a PFO. Replacing these TEE studies...
متن کاملImproved identification of viable myocardium using second harmonic imaging during dobutamine stress echocardiography.
OBJECTIVE To determine whether, compared with fundamental imaging, second harmonic imaging can improve the accuracy of dobutamine stress echocardiography for identifying viable myocardium, using nuclear imaging as a reference. PATIENTS 30 patients with chronic left ventricular dysfunction (mean (SD) age, 60 (8) years; 22 men). METHODS Dobutamine stress echocardiography was carried out in al...
