Echocardiographic Evaluation of Fixed Left Ventricular Outlet Obstruction in Children Pre and Postoperative Assessment of Ventricular Systolic Pressures
نویسندگان
چکیده
Recently, several investigators have utilized the echographically determined magnitude of relative left ventricular posterior wall hypertrophy as a reflection of normalized systolic wall stress to estimate left ventricular systolic pressure noninvasively. In this study, relative wall thickness determined echographically was compared to peak systolic pressure measured at catheterization in 20 children without obstruction to left ventricular outflow and with normal left ventricular function. From these data a relationship, pressure

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...
متن کاملNormal Value of Left Ventricular End-Systolic Elastance in Infants and Children
Background: In certain conditions, there is a need for a specific and improved measure of cardiac performance. Routine methods for assessing left ventricular (LV) function are based on image-analysis or right heart monitoring which do not allow evaluation of ventriculo-arterial interaction. Chen et al presented a noninvasive method allowing measurement of end-systolic pressure–volume relation ...
متن کاملDoppler-Derived Myocardial Performance Index in Healthy Children in Shiraz
Background: Assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. Ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. Objective: A myocardial performance index (MPI) or Tei index has been developed for adult...
