Cardiovascular hemodynamics in mice with tumor necrosis factor receptor-associated factor 2 mediated cytoprotection in the heart.

Introduction: Many studies in mice have demonstrated that cardiac-specific innate immune signaling pathways can be reprogrammed to modulate inflammation in response to myocardial injury and improve outcomes. While the echocardiography standard parameters of left ventricular (LV) ejection fraction, fractional shortening, end-diastolic diameter, and others are used to assess cardiac function, their dependency on loading conditions somewhat limits their utility in completely reflecting the contractile function and global cardiovascular efficiency of the heart. A true measure of global cardiovascular efficiency should include the interaction between the ventricle and the aorta (ventricular-vascular coupling, VVC) as well as measures of aortic impedance and pulse wave velocity.

Background: Many echocardiographic parameters have been proposed to evaluate right ventricular (RV) systolic function. We comprehensively assessed a wide range of quantitative echocardiographic parameters in a single cohort compared with same-day cardiovascular magnetic resonance (CMR).
Methods And Results: 92 subjects were examined prospectively: Group 1 consisted of 46 healthy controls (21 males, 33.
Preoperative right ventricular dysfunction is a strong predictor of 3 years survival after cardiac surgery.

Background: Prognostic value of right ventricular (RV) systolic function is well established in valvular disease, heart failure but has not been evaluated in patients undergoing cardiac surgery.
Objectives: The aim of the present study was to evaluate the prognostic value of preoperative RV dysfunction extensively evaluated on the basis of a large set of echocardiographic parameters [S', RV fractional area change (RVFAC), right myocardial performance index (RMPI), isovolumic acceleration (IVA), RV dP/dt and basal longitudinal strain (BLS)] in a large population of unselected patient awaiting cardiac surgery.
Methods: We prospectively studied 400 consecutive patients referred for cardiac surgery, in a single surgical center.
(90)Y-PET/CT Imaging Quantification for Dosimetry in Peptide Receptor Radionuclide Therapy: Analysis and Corrections of the Impairing Factors.

Purpose: We evaluated the possibility to assess (90)Y-PET/CT imaging quantification for dosimetry in (90)Y-peptide receptor radionuclide therapy.
Methods: Tests were performed by Discovery 710 Elite (GE) PET/CT equipment. A body-phantom containing radioactive-coplanar-spheres was filled with (90)Y water solution to reproduce different signal-to-background-activity-ratios (S/N).
