OBJECTIVES The aim of this study was to evaluate whether cardiac biomarkers, tissue velocity (TVI) and strain imaging, and cardiac magnetic resonance imaging can predict early left ventricular (LV) dysfunction in human epidermal growth factor receptor II-positive breast cancer patients treated with trastuzumab in the adjuvant setting. BACKGROUND Early indexes of LV systolic dysfunction with n...
Bioluminescence has been harnessed for use in bacterial reporter systems and for in vivo imaging of infection in animal models. Strain Xen35, a bioluminescent derivative of Streptococcus pneumoniae serotype 4 strain TIGR4 was previously constructed for use for in vivo imaging of infections in animal models. We have shown that strain Xen35 is less virulent than its parent TIGR4 and that this is ...
n this issue of the Journal, Tugcu et al1 report that by using velocity vector imaging (VVI), as well as tissue Doppler imaging (TDI), subclinical regional right ventricular (RV) dysfunction is diagnosed in patients with obstructive sleep apnea (OSA) who do not have systemic or pulmonary arterial hypertension. They found that the VVIderived RV peak systolic myocardial velocity, strain/strain ra...
Left atrial (LA) functional analysis has an established role in assessing left ventricular diastolic function. The current standard echocardiographic parameters used to study left ventricular diastolic function include pulsed-wave Doppler mitral inflow analysis, tissue Doppler imaging measurements, and LA dimension estimation. However, the above-mentioned parameters do not directly quantify LA ...
