The risk of bacterial endocarditis in infants with bacterial sepsis was assessed by review of clinical and autopsy records (1930 to 1972). There were 12 cases of bacterial endocarditis among 847 patients (1.4%) dying with bacterial sepis; a single survivor was noted during the entire period. Of the 12 autopsy patients, six had underlying congenital heart disease (CHD). Among 61 patients with bacterial sepsis associated with CHD, six acquired bacterial endocarditis (10%), whereas in 786 infants with sepsis but without underlying heart disease, only six developed bacterial endocarditis (0.8%) (P less than .01). There is a high mortality in infants with bacterial endocarditis, and an increased risk of it in infants with sepsis and CHD.

Gangrene of the newborn is an uncommon condition usually resulting from decreased perfusion of a part, usually an extremity. There are a variety of situations which can result in this condition. Knowledge of the exact sequence of events which lead to the insult and the conditions surrounding it is helpful in determining the etiology and as a consequence the treatment of the lesion. In the patient described, direct pressure from the maternal pelvis was probably the contributing factor which led to venous occlusion of the extremity. Arterial thrombosis, emboli, trauma, congenital heart disease, sepsis, dehydration, coagulopathies, and venipuncture are other possible causes which should be considered. The treatment is in general supportive, allowing the ischemic area to demarcate and slough. Range-of-motion exercises and splinting to avoid contracture are helpful in the rehabilitative phase.

A total of 209 consecutive neonate and infant autopsies were reviewed with special attention to papillary muscle necrosis (PMN) of the heart. Associated major pathological findings were analysed for the evaluation of significant pathological accompaniments of PMN. PMN was found in 52 cases among 171(30.4%) neonates and major pathological accompaniments were bronchopneumonia, hyaline membrane disease, hypoxic neuronal change, sepsis, subarachnoid hemorrhage, disseminated intravascular coagulation (DIC) and acute tubular necrosis, among which hypoxic neuronal change and ATN had a statistically significant higher incidence when compared with the control group. (p < 0.005). PMN was found in 13 cases among 38(34.2%) infants and accompaniments were congenital heart disease, sepsis, bronchopneumonia, DIC and hypoxic neuronal change, all of which showed no difference from the control group in incidence. The results imply that PMN is a kind of organ damage in stressed subjects regardless of age, that it is not a special form of myocardial injury in any specific age group including the newborn period, and is possibly of different pathogenesis and significance.

The clinical profile of 28 consecutive patients admitted with infective endocarditis (IE) between 1987 and 1988 was studied. There were 21 males and seven females with a mean age of 24 +/- 11 years. Rheumatic heart disease (RHD) was the commonest underlying disease (68%) followed by congenital heart disease (CHD). Mitral regurgitation with aortic regurgitation were the commonest valvular lesions (47%) in those with RHD while ventricular septal defect was the commonest (43%) in those with CHD. A younger age of onset, complicated course and high mortality were seen in these six patients with acute IE. Persistently positive blood cultures during life or at autopsy were obtained in 21%. Strep viridans was the commonest isolate and was often resistant to streptomycin. 2D echocardicgram revealed vegetations in 96% of patients, the aortic valve (39%) being more commonly affected than the mitral valve (11%). ESR of more than 20 mm drop 1st hour (Wintrobe) was seen in 96%. Thrombophlebitis was a common complication of therapy and cloxacillin the commonest drug implicated. A mortality of 21% as a result of refractory congestive heart failure (CHF) (50%), uncontrolled sepsis (33%) and embolic events (17%) was seen. A rising incidence of culture negative IE, combined aortic and mitral valve disease and CHF is noted.

Diversion of vena caval flow directly into the pulmonary circulation--total cavopulmonary connection--has been tried at our hospital for two years as an alternative to the modified Fontan procedure for surgical treatment of complex congenital heart disease other than tricuspid atresia in 26 cases with six operative mortalities. The causes of death were low cardiac output in four, uncontrollable paroxysmal supraventricular tachycardia in one and airway obstruction in one. Except for one late death which occurred three months after surgery due to sepsis, the 19 patients who survived the operation were followed up for four to 27 months (mean 15 months). All of them improved clinically (NYHA Class 1). Graded bicycle exercise tests were performed in five of them at three to 12 months after surgery, and their exercise tolerance was comparable to that of patients with an atriopulmonary connection. In conclusion, total cavopulmonary connection is an acceptable alternative to the modified Fontan operation for surgical treatment of complex congenital heart disease, although longer follow-up is necessary.

Clinical data from 186 patients (133 males and 53 females) with 190 episodes of infective endocarditis (IE) occurring between January 1981 and July 1991 were studied retrospectively at a large referral hospital in Northern India with the intention of highlighting certain essential differences from those reported in the West. The mean age was much lower (25 +/- SD 12 years, range 2 to 75 years). Rheumatic heart disease was the most frequent underlying heart lesion accounting for 79 patients (42%). This was followed by congenital heart disease in 62 (33%) and normal valve endocarditis in 17 (9%). Twenty-four patients had either aortic regurgitation (n = 15) or mitral regurgitation (n = 9) of uncertain etiology. Prosthetic valve infection and mitral valve prolapse were present in only 2 patients each. A definite predisposing factor could be identified in only 28 patients (15%). Postabortal sepsis and sepsis related to childbirth accounted for 6 and 5 cases, respectively. Only 1 patient had history of intravenous drug abuse. Two-dimensional echocardiography showed vegetations in 121 patients (64%). Blood cultures were positive in only 87 (47%), with a total of 90 microbial isolates. Commonest infecting organisms were staphylococci (37 cases) and streptococci (34 cases). Except for a significantly higher number of patients with neurologic complications in the culture-negative group, there were no differences between patients with culture-positive and culture-negative IE. Of the 190 episodes of IE, the patients had received antibiotics before admission in 110 (58%) instances. A significantly greater number of culture-negative patients had received antibiotics than did culture-positive patients (87 vs 23, p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Renal cortical necrosis, renal medullary necrosis, and combined renal cortical-medullary necrosis result from renal ischemia without vascular occlusion. Renal hypoperfusion and ischemic injury in infants have been ascribed to massive blood loss, hemolytic disease, septicemia, and severe hypoxemia. In a postmortem study we identified 82 cases among 1,638 autopsies during the 20 years between 1970 and 1989 in infants 3 months old or less at the time of death. The frequency of renal necrosis in autopsy cases increased significantly during the last 6 years of the study. The distribution of the renal lesion was cortical in 28, medullary in 23, and combined in 31. Forty infants carried diagnoses of congenital heart disease, 17 of asphyxial shock, 9 of sepsis, 3 of infectious myocarditis, 9 of major malformations, 4 of anemic shock, 1 of vascular malformation, and 1 of gastroenteritis and dehydration. A significantly higher proportion of babies with congenital heart disease had cortical involvement. Comparison of clinical characteristics revealed a significantly higher frequency of prematurity, respiratory distress syndrome, bleeding diathesis, and possibly sepsis in the children with congenital heart disease, suggesting that these factors are important in the pathogenesis of the renal lesion. Fourteen infants underwent cardiac catheterization; there was no demonstrable association between the renal lesions and the use of radiographic contrast medium. We conclude that severe congenital heart disease itself is a risk factor for life-threatening renal cortical and medullary necrosis.

Infective endocarditis is uncommon in young children, especially in the absence of structural heart disease. We report the case of a 2-year-old boy who presented with acute rupture of the mitral valve chordae 6 weeks after an episode of Fusobacterium necrophorum septicemia. His heart had been structurally normal before. Mitral valve replacement was successfully performed. This is the first recorded case of endocarditis in a child caused by necrobacillosis.

Several models of total artificial hearts have been used for transient or permanent circulatory support in patients with decompensation. The most successful and widely used device, however, has been the Symbion total artificial heart. From Dec. 12, 1982, to Jan. 1, 1991, 180 Symbion total artificial hearts were implanted in 176 patients in 28 centers. Five patients received a Symbion total artificial heart as a permanent circulatory support device, whereas 171 patients received the device as a bridge to heart transplantation. Of the 175 bridge devices (171 patients) 141 were Symbion J7-70 hearts and 34 were Symbion J7-100 hearts. Four patients received two total artificial hearts, the second one after the failure of a transplanted heart because of either rejection (two patients) or donor heart failure (2 patients). Most of the recipients were males (152). The age was 42 +/- 12 years (mean +/- SD) with a weight of 74 +/- 14 kg. The most common indications for implantation included deterioration while awaiting heart transplant (36%) and acute cardiogenic shock (32%). The cause of heart disease was primarily ischemic (52%) and idiopathic (35%) cardiomyopathy. Duration of implantation ranged from 0 to 603 days (mean 25 +/- 64 days). One hundred three (60%) patients had the device less than 2 weeks, 37 (22%) between 2 to 4 weeks and 31 (18%) more than 4 weeks. Complications during implantation included infection (37%), thromboembolic events (stroke 7%, transient ischemic attack 4%), kidney failure requiring dialysis (20%), bleeding requiring intervention (26%), and device malfunction (4%). Of the 171 patients, 118 (69%) underwent orthotopic heart transplantation. Actuarial survival for all patients with implants was 62% for 30 days and 42% for 1 year, and for patients with transplants was 72% for 30 days and 57% for 1 year. The main causes of death were sepsis (33%), multiorgan failure (21%), and posttransplant rejection (10%). The results indicate a relative success of this treatment for patients with an otherwise fatal prognosis. Moreover, as the demand for donor organs far exceeds availability, continued investigation of total artificial hearts is justified.

From July 1988 to March 1991, extracorporeal membrane oxygenation (ECMO) was used in 8 infants (newborn to 16 months old) with unoperated cyanotic congenital heart disease and cardiopulmonary collapse, associated with hypercyanotic spells (4 infants), pulmonary hypertensive crises (3) and sepsis (1). Indications for ECMO support were arterial saturations less than or equal to 60% accompanied by hypotension and metabolic acidosis unresponsive to mechanical ventilation with 100% oxygen, paralysis and sedation, and pharmacologic support with inotropes or vasodilators, or both. Venoarterial bypass by carotid/jugular cannulation with flow rates of 100 to 840 ml/kg/min (mean 460) stabilized all patients. Duration of ECMO support ranged from 15 to 840 hours and was associated with transient seizures (1 patient) and renal failure (1). Seven patients underwent palliative (3 patients) or corrective (4) surgical procedures while on ECMO or within 48 hours of decannulation, including 1 patient bridged to double-lung transplantation with a long (840 hours) duration of ECMO. There was 1 operative and 2 late (greater than 1 month after decannulation) deaths, for an overall survival rate of 62%. These 5 survivors all have normal growth and development, and patent neck vessels at the site of cannulation. These early results indicate that ECMO can be effective mechanical support in cardiovascular crises untreatable with maximal conventional medical therapy and can be used as a bridge to successful surgical palliation or repair.
