    Aims Type-1 diabetes mellitus T1DM is among the most common chronic diseases in children. Serious long-term complications include both ultra-morphologic and functional cardiac impairment. Whether these pathologic processes already take place in the early phase of T1DM yet has to be determined. Aim of this prospective, blinded, clinical study was to assess the effect of T1DM on left ventricular LV myocardial function in pediatric patients using quantitative stress echocardiography. Methods We included 40 patients with T1DM aged Conventional and quantitative echocardiography was performed both at rest and during physical exercise on a bicycle. Myocardial strain and strain rate were measured using speckle tracking echocardiography. Results Children with T1DM had increased myocardial contractility both at rest and at all levels of physical stress testing when compared to healthy volunteers. At rest, T1DM patients had significantly higher circumferential strain rate During exercise, diabetic children showed more negative values for longitudinal strain rate Furthermore, in T1DM patients, disease duration inversely correlated with myocardial strain rate and serum HbA1c levels correlated with strain both at rest and during stress testing.

    Basics of Functional Echocardiography in Children and Neonates

    A clinical pediatric cardiologist is expected to be adept at the non-invasive diagnosis of congenital heart disease and those who plan to specialize in echocardiography will need to have knowledge of advanced techniques. Topics covered include: Author Bios Wyman W. Free Access. Summary PDF Request permissions. Part 1: Part 2: Part 3: Part 4: Part 5: A storage system and the possibility to measure structures and velocities off-line are advantageous as it permits comparison between the studies.

    The motion of the heart requires the use of greater frame rate, which is enhanced by beam focusing. Because of very different patient sizes in pediatrics, ranging from the newborn to the adult patient, several transducers with different frequencies are necessary, ideally from 12 to 2. This allows for imaging at different depths. Higher frequency transducers have higher resolution but less depth of penetration than lower-frequency transducers.

    High frequency probes focus at depth of 4—5 cm compared to low frequency probes able to focus at 12—16 cm.

    For this reason, high frequency probes are used in neonates and small children whereas low frequency probes are used in adults with mid-range frequency transducer used in toddlers or small children.

    Special care should be taken to adjust the ultrasound machine to optimize the echo image.

    Most echocardiography machines have a single button to adjust and optimize the image. There remain some simple adjustments that can help optimize image acquisition. The choice of transducer is the most important for enhancing image quality.

    It is important to choose appropriate presets, particularly for color Doppler.

    The image depth should be adjusted so that the heart fills the viewing screen. The 2D gain is used to adjust the strength of the returning echoes and may be controlled in two ways.

    Overall gain may be changed to enhance the brightness of the image. Additionally, time-gain compensation allows changes to the gain at various depth of interest and is controlled by a set of horizontal slide bars. The contrast can be improved by adjusting the compression or dynamic range.

    Echo machines also allow adjustment to the beam focus. The Anatomical Echocardiographic Examination of a Normal Heart In order to remove respiratory artifacts, patients are placed in a left lateral decubitus position whenever possible.

    All planes refer to the axis of heart and not to its position within the body. The different views are obtained from standard windows.

    Segmental approach is the preferred way of imaging the heart, especially for checking cardiac anatomy, and the situs and laterality need first to be determined, especially in the newborn. Thereafter, each cardiac structure is examined and described from the systemic and pulmonary venous return through the atria, ventricles, and great vessels. Each cardiac structure is morphologically recognizable 8 — The atrial septum has a right and left side with the foramen ovale flap on the left side and the Eustachian valve on the right side.

    The left and right atrium RA can be distinguished by looking at their atrial appendages: the left atrial appendage is thin and long, and the right atrial appendage is wide and triangular. The atrioventricular valves always belong to the appropriate underlying ventricle.

    The tricuspid valve is composed of three leaflets, lies more toward the apex, has septal attachments and is associated with the morphologic right ventricle.
