HR-ECUS should be considered complimentary to TTFM. Simultaneous use of the two methods during CABG provides morphological and functional information improving considerably diagnostic accuracy of intraoperative graft verification procedure close to 100%.

In this study, the CVC-to-Ao ratio was a feasible, noninvasive ultrasonographically determined value that correlated well with SPV.

OCT is a promising means for monitoring stent strut coverage and vessel wall healing in vivo, the relevance of which will become even more significant with the increasing use of drug-eluting stents.

Few animal model studies have been conducted in order to evaluate the impact of androgenic anabolic steroids (AAS) supraphysiological doses on the cardiovascular system and myocardial injury. Twenty-five male CD1 mice (8-10 weeks old; 35g initial body weight) were randomized into three AAS treated groups and two control groups. The AAS mice received intramuscular Nandrolone Decanoate (DECA-DURABOLIN), vehicled in arachidis oil, for 42 days, twice per week, with different dosages, studying plasma lipid analysis, cardiac histopathological features, cardiac β (1) adrenergic receptor expression, and the effects of the myocardial expression of inflammatory mediators (IL-1β, TNF-α) on the induction of cardiomyocytes apoptosis (HSP 70, TUNEL), using proteomic and immunohistochemical analysis. The mice had free movements in their animal rooms (two groups) or exercised by running on a motor-driven treadmill the others three groups. Recurring high dose AAS administration and physical training in mice produce significant increase in body weight and for total cholesterol. A moderate increase of the heart weight, cardiac hypertrophy and wide colliquative myocytolysis, were observed in high dose AAS administration and physical training group. The expression of HSP70 and inflammatory cytokine IL-1β, increased in the three AAS-treated groups. TNF- α showed a more extensive expression in the AAS-high dose group. A significant apoptotic process randomly sparse in the myocardium was described. Our data support the hypothesis that the combined effects of vigorous training, anabolic steroid abuse and stimulation of the sympathetic nervous system, may predispose to myocardial injury.

HIA was found to have lower PF, lower intraoperative analgesic failure and faster motor block resolution. In this study HIA was shown to provide some advantages over EA in dogs undergoing commonly performed pelvic limb orthopaedic surgery in a day-hospital regime.
