Abstract

Quantitative assessment of right ventricular (RV) function has been difficult to assess non-invasively secondary to its non-geometric shape and respiratory-variable filling. With recent improvements in ultrasound equipment we are now able to study myocardial velocity changes, which is known as tissue Doppler imaging. To define normal indices of tricuspid pulse tissue Doppler echocardiography imaging in children and infants. We enrolled 100 healthy children with the age of 1 month-15 year old who were referred for echocardiography and had no cardiac lesion in primary echocardiography evaluations. Pulse tissue Doppler images of the lateral tricuspid annular motion were recorded using 4-chamber apical view. Simultaneous electrocardiography was used to correct annular motion time with electrical events. Among our patients 9 were under 1 year, 46 between 10 and 15, 36 between 5 and 10, and 9 between 10 and 15. Infants had decreased peak early diastolic annular velocities and early diastolic annular velocity-to-diastolic annular velocity at atrial contraction ratios compared with the older group. Isovolumic relaxation time difference was not significant between two different groups. In this group of patients, deceleration time and is...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
