The authors undertook a retrospective study of 69 cases of infective endocarditis (IE) in 68 children treated from 1971 to 1992. The comparison between two groups (Group I comprising 34 patients treated between 1971 and 1981; Group II comprising 34 patients treated between 1982 and 1992) based on a review of the literature showed that the natural history of paediatric IE has changed during these two decades: a slight increase in the incidence in young children. The sequellae of rheumatic heart disease play no role in determining IE in France. Congenital heart disease plays a major role (72% of cases) with increasing numbers having undergone surgical treatment for more complex lesions. Mitral valve prolapse has become a more common cause with multiple portals of entry, predominantly buccal and oto-rhino-laryngeal. Blood cultures are positive in 75% of cases, the commonest organisms being Streptococci and Staphylococci, but the frequency of uncommon pathogens is increasing. Echocardiography plays a major role in the diagnosis and inventory of IE (vegetations demonstrated in 64% of cases in Group II). Although mortality is progressively decreasing (3% in Group II) because of more frequent surgical indications (32% in Group II) and more severe sequellae: only 27% of children in Group II were cured without sequellae or aggravation of their previous cardiac lesion.

Twenty children were treated for infective endocarditis (IE) at Our Lady's Hospital for Sick Children during an eleven year period from January 1980 to December 1990. One child had I.E. on two occasions due to different microorganisms. Two had Down syndrome. Congenital heart disease (CHD) was the single most common underlying condition and there was none with rheumatic heart disease. Two had no clinically recognised cardiac anomaly. 13/20 (65%) had acyanotic heart disease and 5/20 (25%) had cyanotic CHD. Among the acyanotic group, ventricular septal defect was most common (6/13); followed by aortic lesions (4/13). There was one case each of coarctation of aorta, patent ductus arteriosus and interrupted aortic arch. Transposition of the great arteries was most common among the cyanotic group (3/5). Four children in the cyanotic group had systemic to pulmonary artery shunts; Blalock Taussig (2), Waterston (1), and aortopulmonary (1). Infection was caused by Streptococcus viridans in 10/20 (50%) and Staphylococcus aureus in 7/20 (35%). Kingella Kingae, Neisseria meningitidis and Streptococcus faecalis were the pathogens in the remainder (15%). Vegetations were detected by echocardiography in 12/19 (63%). The mean duration of antibiotic treatment was 5 weeks (1 day-18 weeks). Surgical intervention was necessary in 4 children (20%). Fifteen children (75%) survived and the mean follow up period was 22.6 months (15 days-6 1/2 years). The overall mortality was 25%.

Cardiac infection usually refers to infective endocarditis (IE) and purulent pericarditis. Though, IE was initially observed in patients with congenital or rheumatic heart disease, currently, persons with prosthetic cardiac valves and with degenerative heart disease account for the majority of the cases and there has been a significant trend toward an increase in the age of patients. Echocardiography, especially, transesophageal echocardiography, has provided valuable information for diagnosis. Since cure requires eradication of all the organisms, bactericidal agents must be used sufficient period to sterilize the vegetation. Overall mortality from recent reports is 10%. Purulent pericarditis almost always occurs in the setting of other serious disease and it's specific signs are often absent, so the disease still carries a high mortality.

Management of aortic valve disease follows traditional algorithms: initial gross diagnosis, noninvasive imaging and quantitation, possible catheterization or angiography, and medical treatment until symptoms of prognosis prediction indicates surgery. Most advances in this subject reflect improved technology and additional data collection therefrom, and subsequent analysis. Noninvasive imaging, especially Doppler echocardiography and nuclear magnetic resonance imaging, enjoy continued refinement. Diastolic dysfunction, a particular pathophysiologic feature of aortic valve disease, has become more clearly characterized. New data reaffirm the old truth that heart failure in infective endocarditis foretells the need for surgery. Though we know more about aortic balloon valvotomy, it is only a temporary treatment. Surgeons still seek the perfect valve prosthesis. Lastly, technology has not lessened the high incidence of rheumatic heart disease in impoverished countries.

Advances in the diagnosis and therapy of congenital heart disease in the past few decades have allowed the survival of young adults who are a fertile substrate for developing bacterial endocarditis. In addition to valvular involvement, young adults with congenital disease may develop infection on the ventricular septum, or in a vascular shunt, a patent ductus arteriosus, or coarctation of the aorta. The incidence of endocarditis in children and adults with congenital heart disease is higher than with rheumatic heart disease or mitral valve prolapse. Infecting organisms, diagnosis, and therapy are similar to acquired heart disease, but the physiologic variations and patient population often add a unique flavor to the management of this group.

During a 45-month period, 50 consecutive patients with infective endocarditis were evaluated at the National Taiwan University Hospital with emphasis on the role of transesophageal echocardiography (TEE) in the management of these patients. Among them, rheumatic heart disease was still the most common underlying cardiac disorder (10/50, 20%), while mitral valve prolapse (8/50, 16%) and congenital heart disease (8/50, 16%) were also frequently encountered. More than one third (19/50, 38%) had no underlying heart disease. Four intravenous drug abusers, quite rare previously in Taiwan, were found during the study period. Native valves involved were mostly mitral valve (n = 18), aortic valve (n = 15), and both mitral and aortic valves (n = 3). Tricuspid valve and pulmonic valve were involved in 3 and 2 patients, respectively. Streptococcus viridans was the leading microorganism isolated (21/50, 42%). Staphylococci and enterococci were found in 9 (18%) and 5 (10%) patients, respectively. Twelve patients (24%) were culture-negative in this series. Embolic complications occurred in 13 patients (26%), with a total of 17 episodes. No significant correlation was found between the occurrence of embolization and the vegetation size or the location of the vegetation, if patients with right-sided valvular vegetation and no identifiable vegetation were excluded. Surgery was needed by 25 patients (50%), and mortality occurred in 6 (12%). TEE was superior to transthoracic echocardiography in the detection of vegetations at the mitral or prosthetic valves. Concerning the associated complications with infective endocarditis, TEE was also superior in estimating the severity of mitral regurgitation, recognizing ruptured chordae tendineae and detecting subaortic complications such as valve ring abscess and mitral valve perforation.(ABSTRACT TRUNCATED AT 250 WORDS)

The pathological findings and the causes of death were reviewed in 108 patients who had received 142 heart valve prostheses (52 mechanical and 90 bioprostheses) at the National Cardiovascular Center in Osaka, Japan, from 1977 to 1991. Rheumatic heart disease was the major underlying disease (60.2%), and the age distribution at death ranged from 21 to 80-year-old. Survival duration after the surgery extended from 0 day to 9 years. Thirty-three patients (30.6%) died of perioperative complications such as myocardial haemorrhage and damage, or from heart failure which had been evident prior to the operation, a cause of death which pre-dominated in patients who died within 1 week of surgery (15/17; 88.2%). Thirty-eight patients (35.2%) died of prostheses-related problems such as prosthetic valve failure (cuspal tears and calcifying destruction of the xenograft), thromboembolism, and prosthetic valve endocarditis. Endocarditis was frequent in patients who had survived longer than 1 year (25/33; 75.8%). None of the patients died of prostheses-related problems within 1 week. Non-infectious valve failure was more common in patients with bioprostheses than in those with mechanical valves; thromboembolism showed the opposite association. Prosthetic valve infective endocarditis was nearly equal in frequency in both types of valve.

With the object of analyzing current characteristics of post-partum and post-abortum infective endocarditis (IE), authors carried out a retrospective study of 15 cases between september 1985 and may 1992. Mean age was 22.2 +/- 4.0 years. Origin of sepsis was delivery (1 case), abortion (14 cases). There was no underlying cardiac lesion in 9 cases, rheumatic heart disease in 6 cases. Infecting organisms were Staphylococcus aureus (n = 6), streptococcus D (n = 3), Clostridium perfringens (n = 2). There were 10 acute and 5 subacute IE, 7 right-sided, 7 left-sided, and 1 right and left-sided IE. Vegetations were determined by transthoracic echocardiography in 12 cases (80%). The main complications were heart failure (15 cases), and pulmonary or arterial embolism (7 cases). Lethality was 53.3% and was not different in tricuspid acute IE and left-sided IE. Treatment was the more difficult as cardiac surgery is expensive or even inaccessible. Accordingly, prevention is primordial. It consist of antibiotic prophylaxis and fight against illicit abortion.

Fifty-one cases of infective endocarditis in 47 Ethiopians over several years are analyzed. There were 32 males and 19 females, average age was 20.5, with 34 < or = 20. Only 2 patients had a known source of infection. Forty-four cases had underlying rheumatic heart disease, 7 had congenital heart disease of which 5 had patent ductus arteriosus. Staphylococcus aureus and S. epidermidis were the most commonly cultured organisms (10 each), only 1 streptococcus was isolated; 28/47 cultured cases had negative cultures. Eight patients (16%) died. In comparison with western studies, this group was much younger and had a higher prevalence of rheumatic heart disease. Mitral valve prolapse and degenerative valvular disease common in the West were not seen in this population. The rate of negative cultures was much higher than the 5-10% reported in the west, most likely due to previous use of antibiotics and problems with culture techniques.

Multiple-valve operation for the young rheumatic patient remains a problem. There is a paucity of information on the results of repair versus replacement in this age group. Between July 1988 and December 1991, 242 patients less than 20 years of age underwent a valve operation for rheumatic heart disease at our institution. Twenty-four (9.9%) of them had simultaneous mitral, aortic, and tricuspid valve procedures. The mean age was 14.71 years. All 24 patients were in functional class III or IV preoperatively. Valvar regurgitation was the predominant lesion. Four patients (16.7%) had active rheumatic myocarditis at the time of operation. Valve repair was attempted in the absence of infective endocarditis. Triple-valve repair was possible in 12 patients (50%). The hospital mortality rate was 16.7%. Reoperation was performed after repair in 9 patients (45%) without any deaths. The reason for reoperation was failure of the mitral valve repair in all patients, and the cause was technical in 3 patients, progression or recurrence of rheumatic myocarditis in 5, and endocarditis in 1 patient. The three late deaths (15%) were in patients who had mitral valve replacement. Valve repair was associated with a higher reoperation rate, and replacement of left-sided valves was associated with a higher early and late mortality. In conclusion, although valve repair would be ideal in the young rheumatic patient, multiple-valve repair is associated with a high reoperation rate.
