[Infectious endocarditis on native valves. Report of a series of 142 surgically treated cases].

The results obtained in a series of 142 patients operated upon, between December 1978 and December 1987, for infective endocarditis on native valve are reported. 61 patients (group 1) had acute progressive endocarditis and 81 patients (group 2) had subacute old-standing endocarditis. In group 1 patients, hospital mortality (i.e. occurring during the first 30 post-operative days) was 11.5 p. 100. During a mean follow-up period of 37.6 months (1.5 to 104.5 months), the survival rates were 52 p. 100 at 72 months and 37.4 p. 100 at 104.5 months. Mechanical desinsertion without persistence or relapse of the infective process, and recurrent endocarditis accounted for 27.8 p. 100 of deaths of known cause. Prognosis was better in group 2 patients. Hospital mortality was 4.9 p. 100, and during a mean follow-up period of 58 months (2 to 124 months) the survival rates were 84 p. 100 at 72 months and 73.4 p. 100 at 124 months. 60 p. 100 of late deaths of known cause were due to heart failure. In native valve infective endocarditis the post-operative diagnosis depends upon the pre-operative haemodynamic status, and the assessment of this status (notably with echocardiography) is a crucial element in the decision to operate.

[Clinical Characteristics and Evolution of Recurrent Infectious Endocarditis in non Drug Addicts].

INTRODUCTION AND OBJECTIVES: Recurrence of infection is observed in a high proportion of patients who have had infective endocarditis in the past. The aim of our study was to evaluate the possible differences between the first and the recurrent episodes of endocarditis, as well as to assess the outcome and prognosis of patients with recurrent endocarditis. PATIENTS AND METHOD: We reviewed a series of 13 episodes of recurrent endocarditis from among 196 cases of infective endocarditis involving non-drug-addict patients in two hospitals from 1987 to 2000. RESULTS: There were no differences between recurrent and first episodes of endocarditis according to age, sex, heart valve involved or causal microorganisms. Prosthetic valve endocarditis was more common in patients with recurrent endocarditis (86% versus 27%; p < 0.001). Although there were no differences in the rate of complications or early surgery, overall mortality was significantly higher in patients with recurrent endocarditis (53% versus 27%: p < 0.05). When early and late mortality were analysed separately, the differences did not achieve significance. CONCLUSIONS: Recurrent endocarditis was frequent in our series (7% of all cases). The features were similar to those of the first episode except for a higher rate of prosthetic valve endocarditis and a higher overall mortality.

[Prevention of infectious endocarditis].

An antibiotic prophylaxis of infective endocarditis is recommended in patients at high risk for infective endocarditis (patients with valvular prosthesis, or cyanogen congenital or obstructive cardiac defect) or those with aortic, mitral or tricuspid valvulopathy, a non-cyanogen congenital or obstructive cardiac defect. Dental procedures (except treatment for superficial decay and preparation for the fitting of prostheses to teeth with intact pulp) are to be carried out under local antisepsis and a prophylactic antibiotics, such as 3 g of oral amoxicillin or in case of allergy to penicillin, 600 mg of clindamycin or 1g of pristinamycin, administered one hour prior to the procedure. A similar prophylaxis is recommended for the procedures on the upper respiratory tract. Amoxicillin, or vancomycin or teicoplanin are recommended for procedures under general anaesthesia. For surgery on the intestinal or urogenital tract, regimens combine amoxicillin with gentamicin, or in case of allergy to penicillin, vancomycin or teicoplanin with gentamicin.

Aortic valve or root replacement with cryopreserved homograft for active infectious endocarditis.

Active aortic endocarditis is a serious condition that carries a high mortality and morbidity. The aim of this study was to analyse results obtained from 24 patients who underwent aortic valve or root replacement with cryopreserved homograft for aortic endocarditis. Eleven patients had native valve endocarditis, and 13 had prosthetic valve endocarditis. The mean age was 47.7 years: there were seven women and 17 men. Causative organisms were staphylococci (12), streptococci (four), serratia (one), candida (one), pneumococci (one), while no organisms were isolated in the remaining five patients. Complete reconstruction of the aortic annulus with homograft conduits was necessary in 20 patients (six total root and 14 mini-root). Infracoronary homograft aortic valve replacement was performed in the remaining patients. One patient died 1 day after the operation from ventricular failure, and two others died after 4 and 6 months as a result of arrhythmia. One patient died of recurrent endocarditis 1 year after surgery. The actuarial survival rate at 3 years was 83.4%. All survivors are symptom-free, with no evidence of recurrent endocarditis. Doppler echocardiography showed minimal aortic regurgitation in four patients.

Infectious endocarditis due to Corynebacterium xerosis.

Corynebacterium xerosis is a rare cause of endocarditis, mainly affecting immunocompromised patients and those with predisposing cardiovascular lesions. While often considered a blood culture contaminant, serious infections by this organism have been reported. C. xerosis endocarditis is associated with poor outcomes that could be potentially improved by early recognition and treatment.

[Value of 2-dimensional echocardiography in the diagnosis of infectious endocarditis].

Cross sectional and simultaneous M-mode echocardiograms were performed on 15 consecutive patients with infective endocarditis, 14 of whom had pre-existing cardiac lesions. Patients were divided into two groups based on the presence or absence of echocardiographically detected vegetative lesions. In 10 out of 15 patients vegetations were present (66%): aortic valve 5, mitral valve 1, tricuspid valve 1, both aortic and mitral valves 1 and left ventricular endocardium associated with aortic valve lesion 2. In this group 3 had systemic embolic episodes and 2 died, whereas none of the 5 patients without detectable vegetations had complications. In 6 the preoperative echocardiographic findings could be confirmed at surgery or autopsy. Emergency surgery without catheterization was performed in 2 patients. Two dimensional echocardiography provides an important non invasive method of assessing a significant percentage of vegetations, but a negative echocardiogram does not exclude infective endocarditis. From the present experience and that of others the detection of vegetations by echocardiography identifies a subgroup of patients with a higher risk for complications in whom early operative intervention without catheterization can be performed. Cross sectional echocardiography may also prove helpful for serial examination of valve vegetations.

[Infectious endocarditis of native and prosthetic valves. A comparative analysis based on 155 cases].

OBJECTIVE: In a retrospective study, we compared the characteristics of native valve and prosthetic valve endocarditis. PATIENTS AND METHODS: All 155 cases of left-sided infective endocarditis in 142 patients admitted at our institution between 1986 and 1992 were analyzed based on their medical records. Native valve endocarditis was found in 119 cases (74 men, 45 women; median age 55, range 29 to 80 years), prosthetic valve endocarditis in 36 cases (11 men, 25 women; median age 63, range 38 to 80 years; 29 cases of late infection). RESULTS: There were more older (P < 0.0005) and more female (P = 0.001) patients with prosthetic valve endocarditis. Most frequently, native aortic valves (53.8%) or mitral prostheses (55.6%) were solely involved. In both groups, Staphylococcus epidermidis was the most frequent isolate followed by Staphylococcus aureus and Enterococci. Symptoms and clinical findings were similar in both groups. In all cases since July 1989, transthoracic echocardiography was suggestive of endocarditis in native valves in 63.9% and in prostheses in 29.2% (P = 0.004), combined with the transesophageal approach in 91.7 and 91.8%, respectively (not significant). Embolism and surgical intervention were about equally frequent in both groups. The in-hospital mortality was 19.3% in native valves and 22.2% in prostheses (not significant). CONCLUSION: Native valve and late prosthetic valve endocarditis are now similar in the spectrum of causative microorganisms, echocardiographic diagnostics, clinical course and prognosis.

Better prognosis of elderly patients with infectious endocarditis in the era of routine echocardiography and nonrestrictive indications for valve surgery.

OBJECTIVE: It has been reported that endocarditis in the elderly may have a poor outcome. Our aim was to assess the different features and prognosis, if any, in the present time. METHODS: Of 103 patients with proven endocarditis, 31 were 65 years or older and 72 were younger than 65 years. Degenerative heart disease was seen more frequently in the elderly (22.5% vs 2.7%, P =.003). Drug abuse and immunodeficiency virus infection were more common in the younger group, as was tricuspid endocarditis (26.3% vs 0%, P <.001). At clinical presentation cardiac failure (41.9 vs 19.4%, P =.02) and leukocytosis (61.2% vs 40.2%, P =.049) were seen more frequently in the elderly. RESULTS: Despite other similar clinical features, it took longer to diagnose older patients (7.2 +/- 6.2 vs 3.2 +/- 3.5 days, P <.001). Enterococcus infected the aged more often (32.2% vs 13.1%, P =.001). During hospitalization, heart failure and embolization tended to be more common in the elderly and the younger group, respectively. There were no significant differences in the incidence of anatomic complications, the need for operation, and overall mortality. CONCLUSION: Although a worse prognosis has been reported in elderly patients with infective endocarditis, the early use of transesophageal echocardiographic examinations and equal therapeutic options provides a similar outcome when compared with younger subjects.
