AIMS The aim of this study was to determine the utility of pulsed wave Doppler tissue imaging in the evaluation of regional left ventricular diastolic function in patients with ischaemic heart disease. METHODS AND RESULTS In 30 normal subjects and 43 patients with ischaemic heart disease, Doppler tissue imaging was performed in each of the 16 segments of the myocardium. The following diastoli...

This article discusses the traditional and more recent echocardiographic measures that have been employed to evaluate atrial function. Conventional parameters commonly used and reported in the literature include the study of the various phases of atrial activity using atrial volume measurements, the peak A wave velocity, its velocity time integral (VTI) and the fraction of atrial contribution (...

BACKGROUND Conventional Doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (LVEDP). However, these parameters have limitations in predicting LVEDP among patients with mitral regurgitation. This study sought to establish whether the correlation between measurements derived from tissue Doppler echocardiography and ...

Aim: Our aim was to gain an idea about testicular injury by comparing the reduced volume, which is one of indirect indicators damage in undescended testes, and evaluating microvascular blood flow superb imaging, also determine whether imaging modes could detect more detail decreased volume testes. Material methods: We compared testes via conventional Doppler color monochrome techniques with con...

This study evaluated the effectiveness of ultrasound, color Doppler imaging and conventional radiography in monitoring the post-surgical healing of periapical lesions of endodontic origin. Fifteen patients who underwent periapical surgery for endodontic pathology were randomly selected. In all patients, periapical lesions were evaluated preoperatively using ultrasound, color Doppler imaging and...

AIMS We evaluated the systolic and diastolic functions of both ventricles from the early neonatal period to adolescence using color tissue Doppler imaging and 2-dimensional tissue tracking echocardiography. METHODS We examined 100 healthy children (aged 1-5 days, n = 20; 1 month, n = 20; 1 year, n = 20; 6-7 years, n = 20; and 12-13 years, n = 20). Blood flow velocities in the mitral and tricu...

Introduction:  In order to assess echocardiographic left ventricular functional indices in patients with differentiated thyroid carcinoma (DTC), after L-T4 withdrawal (short-term overt hypothyroidism) and during TSH suppressive therapy, we have evaluated cardiac hemodynamics in a single cohort study. Methods: 24 patients with DTC were studied in two phases: 1: at least 4 weeks after L-T4 withd...

Mitral annular Doppler tissue imaging (DTI) has been proven to be useful in estimating left ventricular (LV) diastolic filling pressures, and can be applicable to clinical use in adult cardiology. Prior studies have highlighted the technical aspects of DTI and the reproducibility of its measurements; however, recommendations and a systematic approach designed to help sonographers obtain accurat...
