echocardiographic assessment of left ventricle torsion by tissue doppler and velocity vector imaging
introduction left ventricular (lv) twist is believed to store potential energy and plays an important role in generating diastolic suction. recent advances in echocardiography techniques have allowed quantification of lv twist. the aim of the present study was to compare lv twist and torsion in healthy human subjects determined by velocity vector imaging (vvi) and tissue doppler imaging (tdi) a...
cardiac magnetic resonance imaging (cmri) is a well-established noninvasive imaging modality in clinical cardiology. its ability to provide tissue characterization make it well suited for the study of patients with cardiac diseases. we describe a multi-modality imaging evaluation of a 45-year-old man who experienced a near drowning event during swimming. we underline the unique capability of ti...
Life-threatening ventricular arrhythmias (VA) are a major cause of death in patients with cardiomyopathy. To date, impaired left ventricular ejection fraction remains the primary criterion for implantable cardioverter-defibrillator therapy to prevent sudden cardiac death. In recent years, however, advanced imaging techniques such as nuclear imaging, cardiac magnetic resonance imaging, and compu...
introduction: good radiographs are required for endodontic therapy and because some patient’s are intolerant to intraoral films and/or sensors, this can cause complications in endodontic treatment. extraoral film placement can be used to obtain clinically diagnostic and working radiographs. materials and methods: the no. 2 receptor was placed against the model ’ s cheek and centered in the mola...
background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...
introduction low-grade endometrial stromal sarcoma (lg-ess) is a malignant intrauterine tumor that rarely presents with distant metastasis. simultaneous lung and cardiac metastases from lg-ess is also an extremely rare event. case presentation a 42-year-old woman presented with dyspnea and exercise intolerance. she had a history of hysterectomy and left salpingoophorectomy. she underwent second...
Echocardiography accounts for nearly half of all cardiac imaging techniques. It is a widely available and adaptable tool, as well as being a cost-effective and mainly a non-invasive test. In addition, echocardiography provides extensive clinical data, which is related to the presence or advent of different modalities (tissue Doppler imaging, speckle tracking imaging, three-dimensional mode, con...
