BACKGROUND Transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve (MCV) system might represent an alternative to conventional redo surgery in older high-risk patients with a failing aortic valve bioprosthesis. METHODS AND RESULTS Symptomatic patients with failing aortic valve bioprosthesis, aged ≥65 years with a logistic EuroSCORE ≥10 % were considered for treatment. Loc...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether transcatheter aortic valve-in-valve replacement (viv-TAVR) or redo aortic valve replacement (rAVR) is the best strategy in a patient with a degenerative bioprosthetic aortic valve. Altogether, 162 papers were found using the reported search, of which 12 represented the bes...

OBJECTIVES A very high percentage of patients submitted to coronary artery bypass grafting (CABG) develop symptomatic aortic disease requiring surgery upon ageing. The surgical risk of the redo procedure is controversial. We describe our recent experience with patients submitted to this surgery under such conditions. METHODS From July 1999 to July 2010, 51 patients (mean age, 70.3 ± 7.0 years...

cold agglutinins are of unique relevance in cardiac surgerybecause of the use of hypothermic cardiopulmonary bypass (cpb). cold autoimmune diseases are defined by the presence of abnormal circulating proteins (usually igm or iga antibodies) that agglutinate in response to a decrease in body temperature. these disorders include cryoglobulinemia and cold hemagglutinin disease.immunoglobulin m aut...

background and objective: the present study aimed to assess the role of magnesium sulfate (mgso4) sup-plementation after cardiac surgery in pediatric patients, evaluating the incidence of cardiac complications, such as arrhythmia. methods: in this study, 105 children scheduled for elective cardiac surgery were randomly divided into 3 groups. the first group, as the placebo group, received salin...

base deficit is a non-respiratory indicator of acid base status. aim of this study is to assess relationship between the base deficit value in immediate post operative period of cabg and valvular heart disease with cardiopulmonary and in hospital outcome of patient. a total of 136 consecutive with cabg and valvular heart disease scheduled in study. 20 variables were determined during the pre-in...

abstarct background: base deficit is a non-respiratory indicator of acid base status that evaluates the severity of shock at the cellular level. base deficit results from cellular metabolism of pyruvate under anaerobic conditions. in this situation, base deficit is a sensitive marker of the magnitude of anaerobic metabolism and tissue oxygen deficit [1]. several studies have shown a strong posi...

AIM In this paper we report our clinical experience with extended utilization of axillary artery cannulation for cardiopulmonary bypass (CPB) and discuss the indications and the results of the procedure in terms of complications and usefulness. METHODS Between January 1999 and May 2004, 26 patients underwent right axillary artery cannulation for CPB. Fifteen patients presented acute type A ao...

BACKGROUND To evaluate the perioperative risk of redo aortic valve replacement (AVR). MATERIALS AND METHODS Sixty-three patients (53 males, 10 females) underwent redo AVR from 2001-2005. Forty-one bioprostheses had to be replaced for degeneration and/or paravalvular leakage, and 18 mechanical prostheses were changed because of thrombosis and/or paravalvular leakage. Four patients with a bicus...
