Background: The association of right coronary artery (RCA) stenosis in patients undergoing myocardial revascularization for left main coronary artery (LMCA) stenosis affects the prognosis. This study aimed to compare immediate results of patients with isolated LMCA stenosis and those with combined RCA stenosis. Patients and methods: We retrospectively evaluated 107 consecutive patients with LMCA disease who underwent coronary artery bypass grafts. The patients were divided into two groups: isolated LMCA stenosis (n = 36) and LMCA stenosis + RCA stenosis (n = 71). Different variables (preoperative, intra operative and post operative) were compared. Results: Patients with LMCA stenosis + RCA stenosis experienced higher prevalence of diabetes mellitus (p = 0.024) and smoker (p = 0.032). Also left ventricular EF was reduced (p = 0.004). Myocardial revascularization was more complete in patients with LMCA stenosis + RCA stenosis (p = 0.033), but in-hospital mortality rate was higher (12.6% vs 5.5%) in isolated LLMCA stenosis, but it did not reach statistical significance (p = 0.32). Except low output syndrome (LOS) that was frequent in presence of RCA stenosis (p = 0.026), no significant difference was found between groups for other complications. Conclusion: The presence of RCA stenosis in patients undergoing CABG for LMCA disease increases 30 day mortality but without significant impact on overall morbidities.

Aim: Comparing the results of acute phase infectious endocarditis surgery between two periods. Methods and Results: The study is about 2 series, series A between 1993 and 1997, and series B between 1998 and 2012, respectively 13 and 51 patients. The two periods were similar concerning the number of patients per year, which was 3.12 cases/year for series A and 3.64 cases/year for series B. The authors noted a change in epidemiological profile, with an increase of median age (31 y.o for series A and 37 y.o for series B), and the emergency of endocarditis on prosthetic valve (none on series A and 8 cases for series B). Surgical indications and results didn’t change too much, hospital mortality rate was 15.3% for series A and 17.6% for series B. Conclusion: Infectious endocarditis is still a major public healthcare problem in developing countries, despite the development of diagnostic tools and patient care. Prevention is still the major asset in the treatment of this disease.

Background: The aim of this study was to quantify the effect of obesity on early results after coronary artery bypass grafting (CABG). Methods: A retrospective cohort study of patients underwent isolated CABG from January 2000 through December 2012 was conducted. 586 patients were classified into two groups: Obese (n = 100) BMI ≥ 30 kg/m2 and non-obese (n = 486) BMI ≤ 30kg/m2. Results: The obese patients included more women (p 0.01), hypertensives (p = 0.01) and dyslipidemics (p = 0001). The CPB, aortic champ times and number of bypass graft were similar between the groups (p = 0.35, p = 0.51 and p = 0.59 respectively). Also the composite of in-hospital mortality and postoperative complication didn’t differ between the groups. The incidence of perioperative myocardial infarction, and need for inotropic drugs or IABP were significantly less in obese patients (p = 0.028, p = 0.031 and p 0.01 respectively). Conclusions: The current study showed that obesity is not a risk factor of adverse events after CABG and continuous to give another aspect of the “obesity paradox”.

＜正＞ Wurtzite structure monodisperse ZnS quantum dots （QDs） of 1 to 5 nm diameters were synthesized by colloidal chemical method. The strong enhancement of the blue shifted band edge emission from Zn（OH）2 capped ZnS QDs has been observed which indicates the role of surface passivation and supports the quantum size effect. The mismatching of the solvent polarities for stabilizer and QDs precursors lead to detectable far red shifted emission from ZnS core QDs. This emission is attributed to the surface trap states of different energies.

Redo cardiac surgery increases?mortality and morbidity. The aim of this study was to determine if aprotinin was superior to tranexamic acid concerning control bleeding loss after redo valve surgery. A retrospective study was conducted from January 1994 until December 2014. 221 patients underwent redo cardiac valve surgery and separated into two groups: aprotinin group (n?=?85) and tranexamic acid group (n?=?136). Univariate tests were applied for data analysis. A total of 221 patients were enrolled in this study. This cohort was separated into two groups: aprotinin group (n?=?85) and tranexamic acid group (n?=?136). Euroscore in tranexamic acid group was higher: 5.96 ± 3.04 vs.?5.17 ± 2.83 in aprotinin group?(p?=?0.055). There was no statistical difference in postoperative mortality between the two groups (p?= 0.153). No statistical differences were reported concerning: total blood loss (p?= 0.51), red blood cells transfusion (p?= 0.215), reexploration for bleeding (p?= 0.537) and postoperative renal failure (p?= 0.79). There were statistical differences concerning mechanical ventilation time, which is longer in tranexamic acid group (p?= 0.008) and the use of inotropic drug support, which is more frequent in the tranexamic acid group (p?= 0.001). Our results demonstrated that tranexamic acid and aprotinin reduce transfusion requirement and blood loss. Due to financial reason, we chose tranexamic acid in preventing blood loss in redo valve surgery.
