The abdominal left ventricular assist device (ALVAD) is an order of magnitude more effective than conventional intra-aortic balloon pumping (IABP) in unloading and providing circulatory support to the failing left ventricle. This is a report of a unique case which demonstrates that in the absence of pulmonary vascular obstruction or constriction, the ALVAD can substitute for both left and right heart function. A 21-year-old patient with a congenital bicuspid aortic valve developed acute valvular endocarditis which rapidly progressed to congestive heart failure. An operation was undertaken, the mitral and aortic valves were excised and replaced by porcine heterografts, and a fistula from the right sinus of Valsalva to the right ventricle was closed. When coronary circulation was restored, irreversible ischemic contracture of the left ventricle, or "stone heart" syndrome, developed and emergency ALVAD or partial artificial heart implantation was effected. This device functioned as a total artificial heart for nearly six days, while a donor heart was sought. The patient then underwent removal of the ALVAD and cardiac and renal allografting. The transplanted heart functioned well, but the patient expired fifteen days later from gram-negative sepsis.

A review of the literature reveals only one case of neonatal Escherichia coli pericarditis. This is a case report of Escherichia coli pericarditis occurring in a two day old infant. The infant initially presented with lethargy and jaundice but this rapidly progressed into shock. Despite vigorous resuscitative efforts, the infant succumbed and at autopsy 30 cc of purulent fluid were obtained. Cultures of the admission blood and post-mortem pericardial effusion grew Escherichia coli. The clinical diagnosis of pericarditis is often difficult because of vague, nonspecific symptoms and signs. The symptoms are usually those of sepsis plus those of impaired circulation due to mechanical embarrassment by accumulating pericardial effusion. It is difficult to differentiate pericarditis with effusion from myocarditis and pericardial effusion secondary to congestive heart failure. The use of pericardiocentesis as a diagnostic tool and echocardiography are the most helpful techniques presently available for diagnosis. Management consists of vigorous supportive efforts, antibiotics, and drainage of the pericardial effusion. Because of the very high mortality associated with this disorder, a high index of suspicion with a vigorous diagnostic and therapeutic approach to the patient is indicated.

During a 1 yr period, 19 infants less than 2 mo of age were fed intravenously with an infusate composed of glucose, amino acids, electrolytes, and vitamins. The solution was infused at a rate of 200 ml/kg/day or more for periods ranging from 5-247 days. No central venous catheters were utilized; the solutions were always administered through a needle in a peripheral vein. Weight gains similar to those seen with other techniques of intravenous nutrition were observed in all of the patients studied. No instance of fluid overload in the form of pulmonary edema, peripheral edema, or congestive heart failure was seen, and osmotic diuresis was not observed because of the lower tonicity of the infusate. Phlebitis was seen in 1/5 of the infusions, but was reversed by stopping the infusion and applying warm soaks. Three cases of skin slough were observed and two of these healed spontaneously without the need of skin grafting. The advantages of this technique over central venous nutrition are the elimination of the complications related to the central venous catheter, namely, sepsis and superior vena cava thrombosis.

Controversy persists concerning the role of early surgical intervention in severe infective endocarditis (IE). We therefore reviewed 163 episodes of well-documented IE in which 32 cardiac operations were performed during the active phase of IE. Congestive heart failure (CHF) was the principal indication for surgery in 88% (28/32); systemic emboli, 1/32; and persisting sepsis, 3/32. Staphylococcus and enterococcus were the most common infecting organisms in the operative group (44% and 16% respectively). Surgical mortality (11/32,37%) did not differ (p greater than 0.05) from medical mortality (26/131,20%). All 11 operative deaths occurred in patients moribund prior to surgery, including three with preoperative cardiac arrest. Surgical patients undergoing preoperative cardiac catheterization demonstrated marked CHF: a mean left ventricular end-diastolic pressure of 25.3 mm Hg. The mean cardiac index in 8/11 surgical deaths was lower (p less than 0.05) vs surgical survivors: 2.21/min/m2 vs. 3.21/min/m2. Postoperative complications were rare in the 21 surgical survivors. There were no episodes of continued infection, prosthetic dehiscence, or advanced heart block; only one paravalvular leak; and one systemic embolus. These findings emphasize the high medical and surgical mortality in patients with IE, suggest that delayed operative intervention may be a major causative factor resulting in a high surgical mortality, and justify an aggressive surgical approach in patients with valve dysfunction and heart failure. These data indicate that survivors of surgical intervention during active IE have eradication of infection and few postoperative complications.

Twenty-three infants less than age 3 months (mean age 31 days) underwent patch aortoplasty for relief of coarctation of the aorta. All had intractable congestive heart failure, despite aggressive medical therapy. Each infant had other cardiac anomalies, including patent ductus arteriosus (83 percent) and ventricular septal defect (74 percent). All patients underwent closure of the ductus arteriosus and patch angioplasty of the aorta to produce a luminal diameter of at least 16 mm. In addition, 9 of the 17 patients (53 percent) with a large shunt ventricular septal defect underwent pulmonary arterial banding. There was one hospital death 42 days after operation secondary to bowel perforation and sepsis. Hospitalization beyond 21 days postoperatively was always due to other unrepaired cardiac lesions. The three late deaths at 3, 9 and 18 months after operation were associated with additional major anomalies. Fourteen patients have had postoperative catheterization. No gradient was found across the site of coarctation repair, but one patient had a gradient between the left carotid and left subclavian arteries. Surgical repair of critical coarctation of the aorta in infants can safely be offered despite the presence of other cardiac anomalies.

In a study of 31 cases and a review of the literature, Staphylococcus aureus endocarditis was distinguished from that due to other organisms by the absence of prior valvular disease, by the presence of debilitating illness or acute onset, and by a toxic fulminant course. Availability of semi-synthetic penicillins decreased mortality from 90% to about 50%, with death due to heart failure rather than sepsis. Valvular replacement may improve survival if employed at the first signs of cardiac decompensation, rather than after medical therapy has failed to stabilize a downhill course.

With improvements in the techniques of microvascular surgery, the Blalock-Taussig shunt has been applied to smaller infants. We report our experience in 17 neonates (mean age 9 days, mean weight 3.2 kg) who underwent emergency shung operations. The early mortality was 17.6% (3 of 17), with only 1 death (7%) from renal failure and sepsis, in the last 14 patients. Three shunts were patent but inadequate and required a secondary procedure, which was successful in all 3. There were 3 patients with late shunt failures at a mean of 15 months postoperatively, while 2 are still doing well at 15 and 18 months. No patients developed congestive cardiac failure. The late mortality was high (5 of 14), but was due to late shunt failure and was preventable in only 1 patient. These results are encouraging, and we continue to perform the Blalock-Taussig shung in neonates. It is hoped that improvements in technique will reduce the incidence of inadequate shunts.

Patients requiring a major amputation for ischemia are frequently gravely ill. Physiologic amputation obtained by freezing the leg, usually with a tourniquet, will permit delay and intensive preoperative therapy. In an efficient, safe, and convenient method which we have developed and used in 46 patients, a pump circulates antifreeze solution through a specially constructed boot. The last 32 patients so treated have been analyzed as to indications and results. Advantages obtained control of sepsis, correction of diabetic coma, dialysis for chronic renal failure, improvement in congestive heart failure, and improvement in pulmonary function. Four patients had successful below-knee amputations after control of infection that had previously seemed to dictate above-knee amputation. The control of pain and odor, the resultant appreciation of the family, and the lessened demand on nursing staff offer worthwhile benefits in many of the patients, even in some in whom advanced systemic disease prevented survival.

Nineteen patients aged 1 month to 18 years underwent implantation of a cardiac pacemaker and were followed up for up to 9 years (average duration of pacing 54 months). Complete heart block was present in 16 patients and sinus nodal dysfunction in 3. Heart block was presumably of congenital orgin in eight, secendary to cardiac surgery in seven and subsequent to cardiac catheterization in one. Sinus nodal dysfunction was of presumed congenital origin in one and occurred after cardiac surgery in two. Pacing was required because of syncopal attacks in eight patients, three of whom had congestive heart failure or low cardiac output on physiologic studies. It was required in four because of congestive heart failure, in two because of low cardiac output (one with a wide QRS complex), and in five for postoperative rhythm control. With return of sinus rhythm after 2 and 3 months, respectively, pacing was discontinued in two patients. One child was partially corrected disease died within 3 months, one died of wound breakdown and sepsis after 10 months of pacing and one died suddenly 4 years after implantation. All others have returned to normal activity; only one requires cardiac medication. The degree of emotional stability has been striking. Asynchronous and atrial synchronous pacing are of equal therapeutic value. The very small radiofrequency implanted receiver has been useful in younger children. The major problems have been caused by the large size and short longevity of the generators and the child's growth stressing the lead system. Transvenously implanted pacemakers have presented no greater management problems than those placed during thoracotomy.
