During the period 1960 to 1978, 98 patients underwent intracardiac repair of Fallot's tetralogy after palliative operations. Preoperative symptoms were cyanosis, dyspnea, increased fatigue with squatting and hypoxic spells. The hemoglobin concentration varied from 19 to 22 g/100 ml. At correction only 65 of 95 shunts were patent and needed surgical closure. Seventeen early deaths occurred (19%), the main causes being cardiac failure and arrhythmia. One patient died 3 years after correction from pneumonia. The subjective clinical result was excellent or good in all surviving patients. At repeat heart catheterization in 26 patients a high percentage of residual ventricular septal defects and pulmonary stenosis/insufficiency was found. However, the majority of defects were of minimal haemodynamic significance, and so far did not seem to do harm to the patients' subjective function.

A severe staphylococcal septicemia originating from an unknown focus occurred in a 17-year-old patient who had undergone a Rastelli-Ross operation 5 years earlier. The clinical course was complicated by extensive bilateral pneumonia, diffuse intravascular coagulation, and glomerulonephritis. After 4 weeks of intensive conservative treatment, including a daily regimen of 16 Gm. of cloxacillin, the patient was operated upon for a rapidly progressive false aneurysm, which had resulted from dehiscence of the anastomosis between the prosthesis and ventricle. The excised prosthesis proved to be sterile. The postoperative course was uneventful. Cloxacillin treatment was continued for 6 months, initially parenterally and later orally. After discontinuation of therapy, no signs of infection have occurred. Right-sided intracardiac or intravascular prosthetic material may be particularly susceptible to infections originating from the body surface.

Management of symptomatic atrioventricular canal (AVC) in infancy may be difficult. Between July, 1969, and September, 1977, 31 infants with complete AVC presented in congestive heart failure (CHF) to the University of Minnesota Hospitals. Fifteen of these patients have responded to medical management and have been followed as outpatients. The other 16 patients remained in CHF. Six of them died of persistent heart failure within 4 months. The other 10 infants, aged 3 weeks to 1 year (mean 4 months), underwent pulmonary artery banding and seven survived operation. One of the survivors died with apparent pneumonia 1 month postoperatively. Each of the remaining six patients, who have been followed for 9 months to 9 years, had minimal mitral insufficiency and a large ventricular shunt. The three patients dying after banding had significant mitral insufficiency. We believe that pulmonary artery banding is an effective palliative procedure for infants with complete AVC and CHF who have large ventricular shunts and minimal mitral insufficiency.

A 5-year-old boy with acute lymphoblastic leukemia in complete continuous remission developed life-threatening varicella pneumonia and acute respiratory insufficiency (ARI). The child recovered after 92 hours of partial venoarterial perfusion with a membrane oxygenator. Functional asplenia developed. Serial pulmonary function tests after perfusion indicate moderately severe restrictive lung disease which has slightly improved during an 18 month period.

Considerable controversy exists as to whether or not antibiotics should be administered "prophylactically" to patients with penetrating chest trauma. No prospective study of this problem has been reported. Therefore, 75 patients with isolated, penetrating chest injury were randomized prospectively in a double-blind study. Group A patients (38 patients) were given 300 mg. of clindamycin phosphate every 6 hours, beginning with admission and lasting until 1 day following chest tube removal or for 5 days, whichever was shorter. Group B patients (37 patients) were given a placebo on the same schedule. The patients' hospital course, fever, white blood count, culture data, and roentgenograms were recorded serially. Clindamycin-treated patients had a significantly lower incidence of radiographic pneumonia, less fever, and a lower incidence of positive pleural and wound cultures. They acquired empyema less frequently, required fewer operations, and had a shorter period of hospitalization. Antibiotics may be useful, therefore, as adjunctive therapy in the management of penetrating chest trauma.

Immediate bronchial artery reconstitution may be important in the prevention of bronchial anastomotic problems in lung transplantation. To facilitate this reconstitution in circumstances requiring allograft replacement of the right lung, we developed a method for transplanting the left lung together with its bronchial arterial supply into the right hemithorax. With this method, left lungs were allotransplanted into the right hemithorax of nine immunosuppressed dogs. Six recipients survived 1 to 4 weeks. Death resulted from pneumonia or rejection, and there were no bronchial anastomotic problems. Roentgenograms showed that the bronchial artery was patent and that the inverted transplanted left lungs could conform exactly to the thorax without space problems or radiographic abnormalities. Except for the unusual position of the large pulmonary arteries, angiographic patterns, function, and perfusion of the transplanted lungs were often normal and equivalent to those of the recipient's normal left lung. Thus it is possible to transplant a left lung into either hemithorax and immediately reconstitute its bronchial arterial circulation. Bronchial anastomotic problems may thereby be decreased.

Severe mitral regurgitation owing to rupture of chordae tendineae has been repaired in 10 patients by construction of new chordae from autologous pericardium. The site of rupture was the posterior leaflet in eight patients, the anterior leaflet in one patient, and both leaflets in one patient. Cardiac catheterization demonstrated severe mitral regurgitation (average 49%) and a left atrial V wave of 45 mm. Hg. The reconstruction was carried out with pericardium rolled into a chorda with one end attached to the appropriate papillary muscle and the other attached to the flail edge of the mitral valve leaflet being repaired. One patient died on the seventh postoperative day from pneumonia. The remaining nine patients are alive and well (Functional Class I) from 6 months to 9 1/2 years (average 3 years) following the operation. None requires anticoagulants.

We studied the effects of a colloid hypersomolar solution in perservation of lungs for transplantation in dogs. Fresh allografts were compared to lungs stored (4 to 7 degrees C), in Ringer's lactate for 3 hours and in modified silica gel function (MSGF) for 8, 16, and 24 hours before transplantation. Lungs preserved in Ringer's lactate for 3 hours were significantly damaged, and there were no long-term survivors in recipient dogs (1.2 +/- 0.4) (mean +/- S.E.). In contrast, the recipients of lungs preserved in MSGF for periods of up to 24 hours stored MSGF grafts = 10.5 +/- 3.1 days, survival, mean +/- S.E. Fresh Ringer's lactate grafts = 8.5 +/- 2.3 days, mean +/- S.E.; Fresh MSGF grafts = 13.6 +/- 3.8 days, mean +/- S.E.). Arterial blood gas measurements and chest roentgenograms were good methods of assessting the condition of preserved lung allografts. No significant differences were observed between the fresh and MSGF-preserved grafts. Pneumonia and rejection were the most frequent causes of death for both the fresh and MSGF-preserved allograft recipients. We demonstrate that a calloid hyperosmolar solution (MGSF) is a good method for 24 hours hypothermic storage of lung allografts for transplantation.

A prospective, double-blind study comparing a 6 day with a 2 day regimen of cephalothin prophylaxis was conducted among 200 patients undergoing prosthetic valve replacement. No cases of endocarditis occurred during the 2 month follow-up. Sternal wound infection developed in 2.8 per cent of the 6 day group and 2.1 per cent of the 2 day group. Pneumonia developed in 8.5 per cent of the 6 day and 5.3 per cent of the 2 day group; most of the bacteria isolated were susceptible to cephalothin. Urinary tract infection developed more frequently in the 2 day group (17.0 versus 8.5 per cent), particularly during the first 6 postoperative days. Three of 11 patients with no detectable cephalothin in their sera at the close of operation developed staphylococcal wound infections, compared with 2 of 175 patients whose sera contained cephalothin at the close of surgery (p = 0.002, Fisher's exact test). A short course of prophylactic antibiotics is prudent, but there is no justification for prolonging their administration.

Congenital tracheoesophageal fistula (TEF) without esophageal atresia, commonly referred to as H-type fistula, comprises only 4.2% of all TEF's. Four infants with this entity were surgically treated at Santa Rosa Children's Hospital during the period of 1974 to 1977, and their diagnosis, surgical management, and hospital course are described in detail. H-type TEF is characterized by a clinical triad consisting of paroxysms of coughing precipitated by feeding, gaseous distention of the gastrointestinal tract, and pneumonitis. Demonstration of H-type TEF can be difficult and may be accomplished only by repeated examinations. The esophagogram using cinefluoroscopy and image intensification is the primary diagnostic technique utilized. If this is nondiagnostic, then tracheobronchoscopy should be performed in conjunction with ancillary techniques which improve endoscopic yield. Surgical correction can be accomplished through a cervical approach in 80% of cases. Preoperatival treatment of H-type TEF is dependent upon a high index of suspicion, an aggressive diagnostic approach, and prompt surgical correction. Our series of patients demonstrates that early diagnosis is feasible.
