OBJECTIVES In the last decade, cardiac surgery in octogenarians is becoming a routinely performed procedure in our Western countries. The functional benefit of this surgery had already been proved. The aim of this study was to evaluate operative mortality, to identify pre- and post-operative risk factors of early and late mortality, to assess the Euroscore(More)
We retrospectively reviewed the files of 19 extracorporeal life support (ECLS) applications performed after cardiac surgery in 15 patients from January 2002 to December 2004. We placed 16 arteriovenous ECLS applications with oxygenator, 2 venovenous ECLS applications with oxygenator, and 1 biventricular ECLS application without oxygenator (graft dysfunction(More)
BACKGROUND AND AIM OF THE STUDY The study aim was to determine the dynamics and risk factors related to cryopreserved homografts implanted to reconstruct the right ventricular outflow tract (RVOT) during the Ross procedure. METHODS A retrospective study, conducted between 1993 and 2009, included 107 consecutive patients who underwent a Ross procedure with(More)
BACKGROUND AND AIM OF THE STUDY The new-generation bioprostheses are associated with a longer lifespan, and therefore tend to be implanted in younger patients. However, with the increase in life expectancy, the trend is towards a higher rate of repeat valve replacement. Hence, the study aim was to evaluate the present mortality and risk factors for repeat(More)
BACKGROUND The purpose of this study was to find homograft-related factors that might be associated with the development of stenosis after the Ross procedure, as well as to identify the natural dynamics of stenosis and find echographic cutoff values after one year of follow-up that might predict such an outcome. METHODS We followed up 71 patients (mean(More)
OBJECTIVE Although the effects of halogenated agents on both normal and diseased left ventricles have been widely studied, the influence of these anesthetic agents on right ventricular (RV) performance remains less well characterized. This study was undertaken to examine the effects of 2 different concentrations of sevoflurane on RV function, and coronary(More)
The implant of a ventricular assist device is a standardized procedure. However, it carries a high-risk in reoperations, especially if there are patent by-pass grafts. An isolated thoracotomy has been previously described as an alternative access route in these patients, but it offers a limited exposure should intraoperative right-heart failure occur. In(More)
The aim of this study was to determine the surgical results of repair of coarcta tion of the aorta in children under 1 year of age and to assess the risk of recoarctation. Between 1984 and 2004, 206 children under 1 were operated for coarctation of the aorta. Three groups of patients were identified: Group I (isolated coarctation, N=99), Group II(More)
BACKGROUND AND AIM OF THE STUDY Cardiac surgery in octogenarians is now performed routinely, and generally results in a good improvement in functional capacity. The study aim was to evaluate operative mortality and to identify preoperative and postoperative risk factors of mortality. METHODS A total of 200 consecutive patients (79 males, 121 females; mean(More)
Mitochondria-related oxidative stress is a pathomechanism causally linked to coronary heart disease (CHD) and diabetes mellitus (DM). Recently, mitochondrial monoamine oxidases (MAOs) have emerged as novel sources of oxidative stress in the cardiovascular system and experimental diabetes. The present study was purported to assess the mitochondrial(More)
