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.

The records of 20 patients who underwent mitral valve replacement for complications of bacterial endocarditis were reviewed. Although the indications for surgery were the same as those for patients with aortic endocarditis, major emboli (cerebral, coronary or retinal) prompted surgery in 8 of 20 patients, a much higher incidence than reported for surgery in aortic valve endocarditis. Eighteen of the patients had mitral regurgitation; 14 of these had severe congestive heart failure, but the development of congestive failure tended to be more insidious than in patients with aortic endocarditis. Continued septicemia despite appropriate antibiotics was the least common indication for surgery. Sixteen of the 20 patients were salvaged by surgery, although some had major residual deficits, related mainly to preoperative emboli. These results are a marked improvement in the expected 90-100 percent mortality rate for patients with these complications of endocarditis. The main reason for a poor result following surgery was temporization leading to continued deterioration of vital functions preoperatively. Reinfection of the prosthesis did not occur, and we do not consider duration of preoperative antibiotic therapy an important factor in the decision to perform surgery.

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.

This communication describes a new surgical procedure of enlarging the narrow aortic valve ring by extending the aortic incision through the fibrous origin of the aortic leaflet of the mitral valve into this leaflet. A fusiform patch is sutured to the V-shaped defect in the aortic leaflet of the mitral valve and in the aortic anulus. This procedure permits the replacement of the aortic valve by a suitable prosthesis. Between June of 1976 and February of 1978, eight patients underwent this surgical procedure. At the time of operation the patients were between 8 and 50 years old. The estimated enlargement of the aortic root ranged from 10 to 25 mm. The operative technique is described, peculiarities of this method are discussed, and the results are reported. Six to 27 months following operation, the clinical condition of six patients is good. Four patients show no impairment of mitral valve function. In one case, preoperatively diagnosed mitral incompetence persists. In another patient the pericardial patch broke from the aortic leaflet of the mitral valve, so that the valve had to be replaced on the fourth postoperative day. One patient died of myocardial necrosis because of insufficient myocardial protection during operation. One child with acute aortic insufficiency caused by staphylococcal endocarditis and congestive heart failure died of septicemia 3 months postoperatively. Mitral incompetence was not detectable in this child.

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.
