Abstract
Two factors changed the clinical course of infective endocarditis dramatically: 1) The discovery and evolution of techniques for identifying and treating its microbiologic causes and 2) Valvular surgery. We retrospectively evaluated 43 (33.5%) patients (8 female, 35 male) from 4 to 65 years old of 128 patients with infective endocarditis who underwent surgical intervention. Indication for surgery were: Refractory congestive heart failure 14 (32.5%), prosthetic valves 10 (23.2%), large vegetation 6 (13.9%), recurrent endocarditis 4 (9.3%), ring abscess 4 (9.3%), brucella endocarditis 2 (4.6%), staph aureus endocarditis 3 (6.9%) and recurrent emboli 2 (4.6%). 30 to 50% of patients with infective endocarditis are operated during the active phase of the disease, this percentage is higher in case of aortic valve endocarditis, prosthetic valve endocarditis, some microorganisms such as staph aureus, gram negative bacilli, fungus and brucella. We suggest that internists refer patients for surgical intervention with infective endocarditis as early as possible in the active stage of infection.

Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Surgical methods for treatment of tricuspid valve (TV) endocarditis include repair, replacement and partial or complete exicion. The aim of this study was to assess the results of these different techniques.
Methods: Sixty seven patients were enrolled in this retrospective study. This study was carried-out between April 1997 and July 2007 in Imam Khomeini hospital. Decision of methods of choice for surgery was according to intraoperative findings.
Results: The mean age was 25.52±7.35 years and 74.36% were male. The most common bacteria was Staphylococcus areus (62.30%). Most of patients (74.60%) were IV drug abuser. The most common treatment modality was TV reconstruction (56.72%) and after that was TV replacement (29.85%) and the last one was complete TV excision (13.43%). Eight patients (11.94%) needed emergent TV replacement. The morbidity rate was 28.36% and the mortality rate was 13.51%. Thirty seven patients were followed. In follow-up period it was shown that postoperative Ejection Fraction (EF) and End-Diastolic Right Ventricle Diameters (EDRVD) values did not differ from preoperative values, but Pulmonary Artery (PA) pressure and Tricuspid Regurgitation (TR) severity were significantly lower compared with preoperative values. The postoperative function class did not show any changes compared with peroperative values.
Conclusion: Considering the specific epidemiology of patients with infective endocarditis, who are suffering from TV regurgitation, in some patients, it would be better to consider replacement instead of repair. This could be due to sever deformities and diffuse damage of TV leaflets from infection in our patients.

Abstract
Background: Infective endocarditis occurs due to the presence of microorganisms in the endocardium or the heart valves. Nowadays, infective endocarditis is still a major cause of death with an incidence rate of 5 to 7.9 per 100,000 populations. The aim of the study was to determine antibiotic resistance pattern of bacterial agents isolated from blood culture of patients with infective endocarditis.
Methods: In this retrospective study, infective endocarditis patients who were admitted to Sina and Ekbatan hospitals in Hamadan City, Iran, from March 2005 to February 2014, were enrolled. All demographic data, clinical manifestations, physical examinations and echocardiography reports of the patients were recorded in a check list. For all patients, blood cultures in Mueller Hinton agar and antimicrobial susceptibility testing for ceftriaxone, ceftazidime, oxacillin, cefazolin, vancomycin, imipenem, clindamycin, etc. were done by disk diffusion method. All data analyzed by SPSS statistical software, version 16 (IBM, Armonk, NY, USA).
Results: A total of 61 patients with definitive infective endocarditis were included in the study, 50 of them (82%) were males and 11 patients (18%) were females. The mean age of the patients was 37.45±14.79 (range 17-74) years and 37 (60.7%) of the patients lived in urban areas. The mean duration of admission was 20±13.59 days. In addition, 38 patients (62.3%) were injection drug users (IDUs) and 23 (37.7%) non-IDU. Meanwhile, 54 (88.5%) of them had normal valve endocarditis and 7 cases (11.5%) had a prosthetic valve endocarditis. Moreover, the most common underlying disease in the natural valve endocarditis was rheumatoid fever (6.6%). Blood cultures were positive in 44.3% of the patients. The most common isolated organism was staphylococcus aureus in 15 cases (55.55%), which had the highest resistance to oxacillin. Most patients were managed by antibiotic therapy, but 15 cases (24.6%) underwent cardiac surgery. In follow up patients between 3 months to 9 years, 19.7% of the patients had complete recovery and 8.2% of them died.
Conclusion: According to the findings, antibiotic resistance pattern of bacterial agents isolated from blood culture of patients with infective endocarditis was changed.
