Background Outpatient parenteral antibiotic treatment (OPAT) has proven efficacious for treating infective endocarditis (IE). However, the 2001 Infectious Diseases Society of America (IDSA) criteria for OPAT in IE are very restrictive. We aimed to compare the outcomes of OPAT with those of hospital-based antibiotic treatment (HBAT). Methods Retrospective analysis of data from a multicenter, prospective cohort study of 2000 consecutive IE patients in 25 Spanish hospitals (2008–2012) was performed. Results A total of 429 patients (21.5%) received OPAT, and only 21.7% fulfilled IDSA criteria. Males accounted for 70.5%, median age was 68 years (interquartile range [IQR], 56–76), and 57% had native-valve IE. The most frequent causal microorganisms were viridans group streptococci (18.6%), Staphylococcus aureus (15.6%), and coagulase-negative staphylococci (14.5%). Median length of antibiotic treatment was 42 days (IQR, 32–54), and 44% of patients underwent cardiac surgery. One-year mortality was 8% (42% for HBAT; P < .001), 1.4% of patients relapsed, and 10.9% were readmitted during the first 3 months after discharge (no significant differences compared with HBAT). Charlson score (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.04–1.42; P = .01) and cardiac surgery (OR, 0.24; 95% CI, .09–.63; P = .04) were associated with 1-year mortality, whereas aortic valve involvement (OR, 0.47; 95% CI, .22–.98; P = .007) was the only predictor of 1-year readmission. Failing to fulfill IDSA criteria was not a risk factor for mortality or readmission. Conclusions OPAT provided excellent results despite the use of broader criteria than those recommended by IDSA. OPAT criteria should therefore be expanded.
Cardiac surgery induces geometrical and functional changes, which are not clearly explained. Objective: to investigate the physiopathology of the heart after cardiac surgery using advanced techniques of echocardiography. Thirty patients undergoing cardiac surgery had echocardiographic study prior and after surgery. Left and right ventricular (RV) longitudinal displacement and strain were studied with speckle-tracking. Using longitudinal displacement, we defined a static longitudinal reference-point (sLRP) to which the other segments moved during systole. Transversal displacement and global function were determined by conventional-echo. Left and RV segments showed systolic longitudinal displacement towards the apex, which was the sLRP before surgery; and towards the medium segment of lateral RV-wall one week after surgery. The displacement of basal RV segment towards this sLRP was smaller, causing decreased TAPSE. Apical segments showed an inverse displacement towards the new sLRP, and septum displacement was decreased or inverted towards the lateral RV-wall, causing paradoxus septal motion. RV-wall longitudinal strain was reduced (- 23.1 ± 8.6 vs. - 14.6 ± 5.3;p < 0.001), RV transversal fractional shortening was increased (36.5 ± 10.5 vs. 41.7 ± 13; p = 0.011), and the RV fractional area change was unchanged (46.7 ± 9.5 vs. 47.8 ± 11.7; p = 0.625). The medium segment of RV lateral wall, in contact with sternotomy, remains static after surgery and acts as a new sLRP towards which the rest of segments move, explaining the reduction of TAPSE and paradoxus septal motion. The longitudinal strain of the lateral RV-wall gets impaired, but an increase of transversal motion maintains global RV function.
We report a case of a 23-year-old man who was diagnosed with Kawasaki disease that progressed to a coronary aneurysm in the left main coronary artery (LMA). He had suffered from acute coronary syndrome and then underwent an emergent percutaneous coronary angioplasty, in which a polyurethane-covered stent was placed inside the aneurysm. The stent was thrombosed one year later, despite the patient had been treated with anticoagulant and antiplatelet therapy. Emergency percutaneous intervention was then performed. LMA was reopened and stent malposition was observed. Therefore, urgent coronary bypass grafting was performed in which a high degree of competitive flow was observed through the reopened stent. LMA was ligated at the inflow of the aneurysm, resulting in an improvement of graft flow. Left main ligature has not been previously reported.
Objectives (1) To describe the incidence, clinical characteristics, treatment and outcome of Aspergillus Endocarditis (AE) in a nationwide multicentric cohort (GAMES). (2) To compare the AE cases of the GAMES cohort, with the AE cases reported in the literature since 2010. (3) To identify variables related to mortality. Methods We recruited 10 AE cases included in the GAMES cohort (January 2008‐December 2018) and 51 cases from the literature published from January 2010 to July 2019. Results 4528 patients with infectious endocarditis (IE) were included in the GAMES cohort, of them 10 (0.2%) were AE. After comparing our 10 cases with the 51 of the literature, no differences were found. Analysing the 61 AE cases together, 55.7% were male, median age 45 years. Their main underlying conditions were as follows: prosthetic valve surgery (34.4%) and solid organ transplant (SOT) (19.7%). Mainly affecting mitral (36.1%) and aortic valve (29.5%). Main isolated species were as follows: Aspergillus fumigatus (47.5%) and Aspergillus flavus (24.6%). Embolisms occurred in 54%. Patients were treated with antifungals (90.2%), heart surgery (85.2%) or both (78.7%). Overall, 52.5% died. A greater mortality was observed in immunosuppressed patients (59.4% vs. 24.1%, OR = 4.09, 95%CI = 1.26–13.19, p = .02), and lower mortality was associated with undergoing cardiac surgery plus azole therapy (28.1% vs. 65.5%, OR = 0.22, 95%CI = 0.07–0.72, p = .01). Conclusions AE accounts for 0.2% of all IE episodes of a national multicentric cohort, mainly affecting patients with previous valvular surgery or SOT recipients. Mortality remains high especially in immunosuppressed hosts and azole‐based treatment combined with surgical resection are related to a better outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
