A predictive model for early mortality after surgical treatment of heart valve or prosthesis infective endocarditis. The EndoSCORE

BACKGROUND: The aim of this large retrospective study was to provide a logistic risk model along an additive score to predict early mortality after surgical treatment of patients with heart valve or prosthesis infective endocarditis (IE). METHODS: From 2000 to 2015, 2715 patients with native valve endocarditis (NVE) or prosthesis valve endocarditis (PVE) were operated on in 26 Italian Cardiac Surgery Centers. The relationship between early mortality and covariates was evaluated with logistic mixed effect models. Fixed effects are parameters associated with the entire population or with certain repeatable levels of experimental factors, while random effects are associated with individual experimental units (centers). RESULTS: Early mortality was 11.0% (298/2715); At mixed effect logistic regression the following variables were found associated with early mortality: age class, female gender, LVEF, preoperative shock, COPD, creatinine value above 2mg/dl, presence of abscess, number of treated valve/prosthesis (with respect to one treated valve/prosthesis) and the isolation of Staphylococcus aureus, Fungus spp., Pseudomonas Aeruginosa and other micro-organisms, while Streptococcus spp., Enterococcus spp. and other Staphylococci did not affect early mortality, as well as no micro-organisms isolation. LVEF was found linearly associated with outcomes while non-linear association between mortality and age was tested and the best model was found with a categorization into four classes (AUC=0.851). CONCLUSIONS: The following study provides a logistic risk model to predict early mortality in patients with heart valve or prosthesis infective endocarditis undergoing surgical treatment, called "The EndoSCORE"

Surgery for prosthetic valve endocarditis a retrospective study of a national registry

OBJECTIVES: We described clinical-epidemiological features of prosthetic valve endocarditis (PVE) and assessed the determinants of early surgical outcomes in multicentre design. METHODS: Data regarding 2823 patients undergoing surgery for endocarditis at 19 Italian Centers between 1979 and 2015 were collected in a database. Of them, 582 had PVE: in this group, the determinants of early mortality and complications were assessed, also taking into account the different chronological eras encompassed by the study. RESULTS: Overall hospital (30-day) mortality was 19.2% (112 patients). Postoperative complications of any type occurred in 256 patients (44%). Across 3 eras (1980-2000, 2001-08 and 2009-14), early mortality did not significantly change (20.4%, 17.1%, 20.5%, respectively, P  = 0.60), whereas complication rate increased (18.5%, 38.2%, 52.8%, P  -2 mg/dl, chronic pulmonary disease, low ejection fraction, non-streptococcal aetiology, active endocarditis, preoperative intubation, preoperative shock and triple valve surgery were significantly associated with mortality. In multivariable analysis, age (OR = 1.02; P  = 0.03), renal insufficiency (OR = 2.1; P  = 0.05), triple valve surgery (OR = 6.9; P  = 0.004) and shock (OR = 4.5; P  < 0.001) were independently associated with mortality, while streptococcal aetiology, healed endocarditis and ejection fraction with survival. Adjusting for study era, preoperative shock (OR = 3; P  < 0.001), Enterococcus (OR = 2.3; P  = 0.01) and female sex (OR = 1.5; P  = 0.03) independently predicted complications, whereas ejection fraction was protective. CONCLUSIONS: PVE surgery remains a high-risk one. The strongest predictors of early outcome of PVE surgery are related to patient's haemodynamic status and microbiological factors

Surgery for Bentall endocarditis: Short- And midterm outcomes from a multicentre registry

Objectives: Endocarditis after the Bentall procedure is a severe disease often complicated by a pseudoaneurysm or mediastinitis. Reoperation is challenging but conservative therapy is not effective. The aim of this study was to assess short- and midterm outcomes of patients reoperated on for Bentall-related endocarditis. Methods: Seventy-three patients with Bentall procedure-related endocarditis were recorded in the Italian registry. The mean age was 57 \ub1 14 years and 92% were men; preoperative comorbidities included hypertension (45%), diabetes (12%) and renal failure (11%). The logistic EuroSCORE was 25%; the EuroSCORE II was 8%. Results: Preoperatively, 12% of the patients were in septic shock; left ventricular-aortic discontinuity was present in 63% and mitral valve involvement occurred in 12%. The most common pathogens were Staphylococcus aureus (22%) and Streptococci (14%). Reoperations after a median interval of 30months (1-221 months) included a repeat Bentall with a bioconduit (41%), a composite mechanical (33%) or biological valved conduit (19%) and a homograft (6%). In 1 patient, a heart transplant was required (1%); in 12%, a mitral valve procedure was needed. The hospital mortality rate was 15%. The postoperative course was complicated by renal failure (19%), major bleeding (14%), pulmonary failure (14%), sepsis (11%) and multiorgan failure (8%). At multivariate analysis, urgent surgery was a risk factor for early death [hazard ratio 20.5 (1.9-219)]. Survival at 5 and 8 years was 75 \ub1 6% and 71 \ub1 7%, with 3 cases of endocarditis relapse. Conclusions: Surgery is effective in treating endocarditis following the Bentall procedure although it is associated with high perioperative mortality and morbidity rates. Endocarditis relapse seems to be uncommon
