Pulsed Doppler echocardiography for diagnosis of ventricular septal defects.
In order to assess the performance of pulsed Doppler echocardiography and to examine the factors affecting its reliability for the diagnosis of ventricular septal defects, 51 patients, in whom angiographic studies had recently been performed, were investigated before and after operation by this technique. The diagnosis was correct in all cases with left-to-right shunt, when the defect was locat...
متن کاملPulsed Doppler Echocardiography in the Diagnosis of Ventricular Septal Defect and Patent Ductus Arteriosus
some limitations and it is unable to detect small abnormalities beyond the imaging resolution of the apparatus. Ventricular septal defects (VSDs) can only be detected if they are sufficiently large or are associated with certain anatomical malformation (Magherini et al., 1983). Accurate demonstration of a patent ductus arteriosus (PDA) is limited due to echo dropout which makes visualisation of...
متن کاملDiagnosis of ventricular septal defect by pulsed Doppler echocardiography. Sensitivity, specificity and limitations.
The M-mode echocardiographic findings of ventricular septal defect (VSD) are nonspecific. A specific pulsed Doppler echocardiographic (PDE) diagnosis of VSD can be made by following the turbulent VSD jet through the septum. To assess the sensitivity, specificity and limitations of PDE diagnosis of VSD, 105 children undergoing cardiac catheterization were examined by PDE. These children had a va...
متن کاملBidirectional shunt in uncomplicated atrial septal defect.
The presence of right to left shunts at atrial level in 40 patients with an uncomplicated atrial septal defect was determined by measuring the pulmonary vein to systemic artery oxygen stepdown . In six patients (group 1) a sizeable right to left shunt was found: left atrial oxygen stepdown was greater than or equal to 0.7 vol%, mean right to left shunt 0.67 1/min/m2 (range 0.36-1.0), and arteri...
متن کاملNormal left ventricular systolic time intervals assessed by pulsed wave Doppler echocardiography in the Turkmen horse of Iran
The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contrac...
