BackgroundThe reoperation for isolated tricuspid regurgitation in rheumatic population is rare and still unclear and controversial because of the rarity of publications. The aim of this study was to analyze short and long-term results and outcome of tricuspid valve surgery after left-sided valve surgery in rheumatic patients.MethodsTwenty six consecutive rheumatic patients who underwent isolated tricuspid valve surgery after left-sided valve surgery between January 2000 and January2017 were retrospectively registered in the study. The mean age was 48.2 ± 8.6 years with 8.3% as sex-ratio (M/F). EuroSCORE was 6.1 ± 5 (range 2.5 to 24.1). The mechanism of tricuspid regurgitation was functional and organic in respectively 14 (53.8%) and 12 cases (46.2%). Ten patients (38.5%) had previous tricuspid valve repair. Surgery consisted of 15 ring annuloplasty and 11 tricuspid valve replacement (5 bioprostheses and 6 mechanical prostheses). Follow-up was 96.1% complete, with a mean follow-up of 55.6 ± 38.8 months (range 1 to 165).ResultsThe operative mortality rate was 15.4% (n = 4) and the cumulative survival at 1, 5 and 10 years was respectively 80% ± 8%, 75.6% ± 8.7% and 67.2% ± 11.1% with no significant difference at 8 years between tricuspid valve replacement (80% ± 12.6%) and repair (57.6% ± 16.1%) (p = 0.5). Multivariable Cox regression analysis revealed that ascites (HR, 5.8; p = 0.01), and right ventricular dysfunction (HR, 0.94; p = 0.001) were predictors of major adverse cardiac events. There were no recurrence of tricuspid regurgitation and no structural or non-structural deterioration of valvular prostheses.ConclusionThe reoperation of rheumatic tricuspid regurgitation should be considered before the installation of complications such as right ventricular dysfunction and major signs of right heart failure. Despite the superiority of repair techniques, tricuspid valve replacement should not be banished.

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/m 2 and non-obese (n = 486) BMI ≤ 30kg/m 2 . 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".

Although the majority of patients with perimembranous ventricular septal defect and septal aneurysm remained asymptomatic, some of them presented with serious complications during adulthood and thus required high risky surgery. In accordance with other rare condition, the incidence and natural history have not been well documented. This case describes the occurrence of a septic pulmonary emboli associated with right ventricular outflow tract obstruction in a young child.

IntroductionCardiac surgery is frequently needed during active phase of infective endocarditis (IE). The purpose of this study was to analyze the immediate and late results and determine the risk factors for death.MethodsWe retrospectively reviewed 101 patients with IE operated in the active phase. The mean age was 40.5 ± 12.5 years. 16 patients (15.8%) were diagnosed with prosthetic valve endocarditis (PVE). 81 (80.9%) were in NYHA functional class III-IV. Blood cultures were positive in only 24 cases (23.9%).Resultsin-hospital mortality rate was 17.9% (18 cases). Multivariate analysis indentified five determinant predictor factors: congestive heart failure (CHF), renal insufficiency, high Euroscore, prolonged cardiopulmonary bypass time (> 120 min) and long ICU stay. The median follow-up period was 4.2 (2-6.5) years. Overall survival rate for all patients who survived surgery was 97% at 5 years and 91% at 10 years.ConclusionDespite high in-hospital mortality rate, when patients receive operation early in the active phase of their illness, late outcome may be good.
