• 1. Echocardiography: The system's exceptional imaging quality and versatile modes make it a powerful tool for echocardiography, enabling clinicians to visualize heart structures, evaluate valve function, assess myocardial performance, and detect cardiac abnormalities. (medicareexel.net)
  • Pulsed-wave tissue Doppler imaging (TDI) of the left ventricular longitudinal myocardial velocity associated with atrial contraction (A'), both at the level of the interventricular septum and the LV free wall, was also used as an indicator of LA function. (openveterinaryjournal.com)
  • Assessment of myocardial longitudinal function has proved to be a sensitive marker of deteriorating myocardial function in aortic stenosis, demonstrated by both color Doppler tissue imaging and recently by two-dimensional speckle-tracking echocardiography. (thoracickey.com)
  • Since the era of M-mode echocardiography, many new methods have been added to the echocardiographic toolbox, and today we can assess myocardial performance with both tissue Doppler velocities and two-dimensional (2D) speckle-tracking echocardiography in relation to systolic and diastolic function and global, regional, and multidirectional performance. (thoracickey.com)
  • These include two-dimensional (2D) imaging for visualizing cardiac structures, Doppler imaging for assessing blood flow patterns, color flow imaging for detecting abnormalities in blood flow, and tissue Doppler imaging for evaluating tissue motion and strain. (medicareexel.net)
  • Although echocardiography has long been the principal imaging modality in this disorder, others including positron emission tomography (PET) and cardiac computed tomography (CT), and to a lesser extent intracardiac echocardiography (ICE), play an increasing role. (emedicalacademy.com)
  • It seems intuitively correct to monitor cardiac function to identify patients with worsening aortic stenosis, and measures of longitudinal cardiac function, evaluated by color Doppler tissue imaging (DTI) and 2D STE, seem especially appealing. (thoracickey.com)
  • The aims of this study were to evaluate the use of comprehensive Doppler echocardiography as a guide during Biv pacemaker optimization in patients after cardiac resynchronization therapy and to evaluate the feasibility of S 3 intensity to be a cost-efficient parameter for Biv pacemaker optimization compared with Doppler echocardiography. (thoracickey.com)
  • Comprehensive echocardiographically guided Biv pacemaker optimization produces significant improvement in Doppler echocardiographic hemodynamics, a reduction in S 3 intensity, and an improvement in functional class in patients after cardiac resynchronization therapy. (thoracickey.com)

  • The assessment of aortic valve stenosis (AS) severity based on Doppler velocity and pressure gradient is flow dependent. (emedicalacademy.com)
  • The aim of this study was to compare velocity (color Doppler tissue imaging) and deformation (two-dimensional speckle-tracking echocardiography) in relation to global and regional longitudinal function in asymptomatic and severe symptomatic aortic stenosis. (thoracickey.com)
  • Advocated Doppler parameters include the aortic velocity-time integral (VTI), diastolic mitral inflow pattern, Doppler tissue imaging, and Doppler-derived dP/dt. (thoracickey.com)
  • In previous studies, tissue velocities measured by color DTI have proved to be more robust measures of longitudinal function compared with the newer technique with 2D STE, but regional function may not be reflected accurately with color DTI, because of tethering. (thoracickey.com)
  • Diagnosis of severe AS, which is defined as an aortic valve area (AVA) ≤ 1.0 cm2, is done with echocardiography. (emedicalacademy.com)
  • demonstrated that longitudinal shortening, measured by M-mode echocardiography, was reduced in patients with aortic stenosis compared with normal subjects and patients with aortic or mitral regurgitation. (thoracickey.com)
  • The study population of 231 patients with aortic stenosis was recruited from March 2008 to January 2012 from two parallel studies investigating the use of multidetector computed tomography and echocardiography in asymptomatic patients ( n = 104) and symptomatic patients scheduled for aortic valve replacement, with or without coronary bypass grafting ( n = 127).

  • Doppler echocardiography of mitral inflow or aortic outflow or both has been validated and advocated to guide biventricular (Biv) pacemaker optimization. (thoracickey.com)
  • 5. Stress Echocardiography: The system is also equipped with stress echocardiography capabilities, allowing clinicians to assess the heart's response to physical stress. (medicareexel.net)
  • For each dog, two-dimensional (2D) echocardiography was performed to assess LA diameter and volume for each phase of the LA cycle and to assess complete, passive, and active LA function. (openveterinaryjournal.com)
