Abstract
To assess the contributions of systolic and diastolic dysfunction to congestive heart failure (CHF) in ventricular septal defect (VSD), we studied 13 children with VSD at catheterization using a Millar catheter. Eight children had CHF, whereas five did not. Phenylephrine was infused at a rate of 5 micrograms.kg-1.min-1, and M-mode echocardiography and pressure were measured simultaneously. Systolic left ventricular (LV) function was assessed by maximum LV pressure (LVP), rate of pressure development (dP/dt), and by the end-systolic pressure-diameter relation (ESPDR). Systolic myocardial function was assessed by the end-systolic stress-strain relation. Diastolic chamber function was assessed by the isovolumic relaxation time constant (tau) and by the end-diastolic pressure-diameter relation (EDPDR). Diastolic myocardial function was measured by the end-diastolic stress-strain relationship. With phenylephrine, maximum LVP increased from 99 +/- 5 to 119 +/- 4 mmHg with CHF and from 106 +/- 6 to 149 +/- 10 mmHg without CHF. +dP/dt was lower with CHF (1,582 +/- 96 mmHg/s) than without CHF (2,300 +/- 200 mmHg/s). The maximum slope of the ESPDR was 39 +/- 8 with CHF and 94 +/- 14 mmHg/cm without CHF. The maximum slope of the midwall stress-strain relation was 223 +/- 37 with CHF and 395 +/- 93 g/cm2 without CHF. tau was 25 +/- 2 without CHF compared with 32 +/- 3 ms with CHF. The EDPDR was shifted leftward with failure, whereas the stress-strain relation was similar for all patients. CHF in patients with VSD results primarily from systolic dysfunction.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Twenty-two late survivors of Mustard repair of transposition of the great arteries underwent treadmill exercise testing to assess exercise endurance, and radionuclide cineangiography to measure rest and exercise right ventricular (RV) and left ventricular (LV) ejection fraction (EF). Mean age at Mustard repair was 1.8 +/- 2.4 years and at initial exercise study 14.1 +/- 4.5 years. All patients were asymptomatic at study entry. Treadmill endurance time (9 to 12 minutes) was within the normal range for age in 18 of 20 patients. LVEF and RVEF at rest were within normal limits (55 +/- 8% and 52 +/- 9%, respectively). All LVEFs and RVEFs during exercise were also within the normal range (64 +/- 8% and 57 +/- 9%, respectively). However, the magnitude of increase in EF (rest to exercise) was subnormal for the right ventricle in 7 patients and for the left ventricle in 2 patients. Exercise RVEF was higher in patients with simple transposition who underwent repair at < 1 year of age than in those who underwent operation at age > 1 year (62 +/- 10% vs 52 +/- 7%). Serial study in 6 patients revealed no change in average RVEF or LVEF after an average interval of 4.4 years. One patient with complex transposition subsequently developed refractory congestive heart failure requiring cardiac transplantation. It is concluded that exercise endurance and LVEF and RVEF at rest and exercise are generally well preserved up to 19 years after Mustard repair, particularly in cases of simple transposition of the great arteries repaired before 1 year of age.

Abstract
In spite of recent advances in neonatal open repair for complex cyanotic heart disease, some patients require palliation with a systemic-to-pulmonary artery shunt. We report a 5-year experience (1985-1990) with 112 Blalock-Taussig shunts. Forty-six of the 92 patients had some variant of tetralogy of Fallot, with a wide spectrum of diagnoses in the remainder. The median age at surgery was 3 months. A classic Blalock-Taussig shunt was done in 26% (group I), and a 4- or 5-mm PTFE graft was utilized in the remainder (group II). The technical aspects of each of the procedures are reviewed. There were three early deaths in the entire group, none of them related to Blalock-Taussig shunt function. There was no incidence of early shunt insufficiency, bleeding, infection, limb ischemia, or pulmonary artery distortion. There was a 21% incidence of clinical congestive heart failure, seen somewhat more commonly in group I. The overall need for reshunting/open repair was similar in both groups, but there was a statistically longer interval between the initial Blalock-Taussig shunt and the second procedure in group I (21.6 vs 12.4 months). The Blalock-Taussig shunt remains a safe, reliable, and effective means of increasing pulmonary flow.

Abstract
OBJECTIVES AND BACKGROUND Congenital aortic regurgitation is rare as an isolated lesion. We describe seven children with no physical features of the Marfan syndrome in the patients or their families and no other cardiac lesions who had congenital valvular aortic regurgitation. METHODS From 1954 to the present, seven children with auscultatory and physiologic characteristics of aortic regurgitation were evaluated for a total of 108 patient-years. We report on their natural history, clinical and laboratory findings, management and outcome. RESULTS In five of the seven children congenital aortic regurgitation was diagnosed in infancy. In four, progressive severity of the regurgitation led to valve replacement at age 3, 10, 15 and 20 years, respectively, and to resection of an aneurysm of the ascending aorta in the 10-year old patient. Two patients had cystic medial necrosis on aortic biopsy. One of these patients died after reoperation for dissecting aneurysm of the thoracic aorta at 22 years of age; the other died after dissection and rupture of the ascending aorta at age 25 years. After obstructing pannus developed, the 3-year old patient underwent replacement of the St. Jude valve at age 10 years. The other three patients were asymptomatic at last follow-up at age 8, 10 and 20 years, respectively. CONCLUSIONS Supportive management is recommended until it becomes necessary to intervene surgically when regurgitation becomes severe. The need for surgical treatment is indicated by the appearance of a diastolic thrill, left ventricular strain on the electrocardiogram or other evidence of left ventricular dysfunction on the echocardiogram or exercise stress testing by treadmill or radionuclide cineangiocardiography. Close follow-up of these patients is important to detect progression of aortic regurgitation, especially in the presence of cystic medial necrosis.

Abstract
A cyanotic, tachypneic newborn was diagnosed to have double-outlet right ventricle of the Taussig-Bing type. Cardiac failure did not respond to medical treatment or surgical palliation. Postmortem examination revealed two ventricular septal defects (VSDs), one a malalignment VSD in the membranous septum and adjacent tissue and the other in the anterosuperior part of the muscular septum. The D-malposed aortic root emerged mainly from the right ventricle, with aortic-mitral continuity. The larger posterolateral pulmonary root arose almost entirely from the right ventricle, confluent with the muscular VSD, and unrelated to the mitral valve. Its right ventricular aspect was obstructed by hypertrophied infundibulum. This unique malformation of the heart functioned as a double-outlet right ventricle of Taussig-Bing type. In addition, however, the malformation had elements of tetralogy of Fallot because of the malaligned VSD and hypertrophied conal musculature (although pulmonary flow was excessive), and also of complete transposition of the great arteries because of the arrangements of the two VSDs, which favored aortic flow from right ventricle and pulmonary blood flow from the left ventricle. Thus, a single heart presented similarities to three anatomic and functional entities.

Abstract
Gamma globulin administered in a single dose of 1 g/kg of body weight intravenously caused prompt clinical improvement in 27 of 32 consecutive children with Kawasaki disease treated by the 12th day of illness. Response was equally good for the 20 children treated in the first week and the 12 treated in the second week. Fever and clinical signs abated within the first day after treatment, the mean white blood cell count normalized by 48 hours, and the sedimentation rate continued to be elevated for about 2 weeks, while the platelet count rose during the first 2 weeks after treatment and returned to normal approximately 1 month after treatment. Five children with incomplete relief needed more than the single dose before resolution of signs and symptoms occurred. Coronary aneurysms in 2 patients before treatment regressed by 2 weeks. No patient developed coronary aneurysms. No child had sequelae of Kawasaki disease at a follow-up of 2 to 31 months. We believe that although this was a one-arm, uncontrolled pilot study, the results suggest that this protocol provides a safe, flexible, and effective treatment for acute Kawasaki disease.

Abstract
Epidemiologic and clinical features of Kawasaki disease in 106 patients seen between 1980 and 1986 at The New York Hospital in midtown Manhattan were compared with those in large series from the United States, Canada, and Japan. Dissimilarities in our Kawasaki disease experience included ethnic heterogeneity of our patients (50% white, 18% black, 16% Hispanic, and 16% Oriental) and, in comparison with the Japanese experience, an older mean age (3 1/2 vs 1 1/2 years) with fewer children less than 2 years of age (32% vs 50% to 60%). In comparison with the general population of the geographic urban and suburban referral area for our hospital and in comparison with our general pediatric population, Oriental children with Kawasaki disease were overrepresented (16% vs 2%). More families of children with Kawasaki disease were members of the upper and middle class (73%) than were the population seen in general pediatrics (31.7%) at our hospital. Personal interviews with 63 families of children with Kawasaki disease and 63 control families with children paired for ethnic group, sex, and age revealed no epidemiologic differences except for use of rug shampoo within 1 month of onset in 16 episodes in 15 children with Kawasaki disease in 14 families (22% of families) compared with two families of control children (3%) (P less than .001).

Abstract
To determine whether changes in ECGs correlated with abnormalities in echocardiograms in children with acute and convalescent Kawasaki syndrome, we undertook a retrospective analysis of 44 patients examined during the first 2 weeks of illness and followed for at least 6 months, 31 for longer than 1 year. We analyzed 360 ECGs, 282 echocardiograms, and clinical status. Results of echocardiography showed 18 children with myocardial dysfunction, pericardial effusion, and/or coronary arterial abnormalities (41%); 26 children had no abnormalities. All 18 of the former and all but 10 of the latter had abnormalities on serial ECGs that normalized on recovery. Thirty-four of 44 patients (77%) had ECG abnormalities. These abnormalities were most prevalent in the first month: 68% appeared in the first week, about 50% in the second to fourth weeks, 16% at 2 months, and 10% at 3 months. The type of ECG change did not predict the type of echocardiographic abnormality, except that low voltage of QRS was found only with pericardial effusion. The most frequent early changes were in T waves, which were flattened in 28 (64%). Later 12 patients had high, peaked, abnormal T waves. Prolonged PR interval occurred in 13 patients, seven of whom had echocardiographic abnormalities. Of six with prolonged QT interval, four had abnormal echocardiograms. The possibility of having an abnormal echocardiogram increased with the number of ECG changes: from 0 risk with no change to 37% for one, 47% for two, 80% for three, and 100% for four changes in serial ECGs. Both ECGs and echocardiograms are important in early and subsequent evaluation of these patients. Inasmuch as the ECGs showed abnormalities in 77% whereas echocardiograms showed changes in 41%, we believe that serial ECGs in comparison with prior tracings offer the more sensitive noninvasive indicator of pancarditis in young children during acute and convalescent Kawasaki syndrome.

Abstract
Since January 1980, 110 children having 113 attacks of Kawasaki syndrome were studied. Age at onset was 7 weeks to 12 years (mean 3 6/12 years, median 2 9/12 years); 77% were younger than 5 years of age; the male to female ratio was 1.8; racial distribution was 52% white, 19% black, 14% Hispanic, and 16% Asian. Protocol of management consisted of high-dose aspirin (100 mg/kg/d) until afebrile, and then 81 mg every day until free of coronary aneurysm. Two-dimensional echocardiograms were done weekly during the acute stage, at 2 and 6 months after onset, and yearly if a coronary abnormality was detected. At 1 month, 51 coronary arterial abnormalities were present in 25 patients. Risk factors for a coronary abnormality were duration of fever greater than or equal to 2 weeks, level of platelet count, marked elevation of ESR, and age younger than 5 years. No statistically significant difference in incidence of aneurysms was detected between patients on high-dose aspirin and those on medium-or low-dose aspirin.

Abstract
Echocardiography and Doppler have revolutionized diagnosis and management in pediatric cardiology. The information generated by these noninvasive studies on appropriate patients permits the pediatric cardiologist to make more accurate diagnostic assessments than previously possible. In turn, the pediatrician and the family are better informed regarding the management and care of the patient.

Abstract
The advancements in Doppler methodology in the past decade have dramatically changed the way we assess children with heart disease. Techniques to determine pressures, gradients, shunt flows, and regurgitant lesions have shifted the noninvasive studies into areas that were strictly the venue of catheterization a decade ago. The more recent color Doppler developments take the 2DE image one step further by providing some of the flow visualization previously available only through angiography. When applied to appropriate clinical settings Doppler methodology will continue to provide us with increasingly sophisticated and precise definitions of intracardiac physiology.

Abstract
Polymorphonuclear leukocytes (PMNL) from two individuals with congenital Pelger-Huet anomaly (PHA) were examined to determine whether functional or metabolic defects accompanied the known morphological abnormality. No abnormalities of the PHA cells, as compared to normal control cells, were found when tested for quantitative leukocyte enzyme activities, nitroblue tetrazolium reduction, hexose monophosphate shunt activity, superoxide production, generation of chemiluminescence, or iodination. The PHA cells, as compared to normal PMNL, demonstrated normal chemotaxis and random migration, as well as bactericidal activity.

Abstract
Food satiation and oral hygiene punishment were used to treat the non-life-threatening rumination of two institutionalized profoundly retarded persons. Satiation consisted of allowing the clients to eat until a satiation criterion of food refusal was achieved or until two full meal portions were consumed. The oral hygiene procedure consisted of cleansing the clients' teeth and gums with Listerine for 2 minutes following each instance of rumination. In the formal study, three conditions--baseline, satiation, and satiation plus oral hygiene--were used following the lunch meal in a multiple-baseline across-subjects design. One client's rumination decreased from an average of 89.5% during baseline to 48.8% during the satiation condition and to 3% during satiation plus oral hygiene. The second client's rumination decreased from a baseline average of 49.9% to 7.9% during satiation and to 1.4% during satiation plus oral hygiene. Generalization probes taken following the breakfast and dinner meals showed a systematic decline in rumination as the various conditions were implemented following the lung meal. In the 16-week follow-up, rumination was treated following all meals with oral hygiene, and satiation was used at one of the daily meals for 1 week on a rotating basis. Rumination remained at a near-zero level following all meals throughout the follow-up. Thereafter, a maintenance program was conducted by the ward staff. The satiation plus oral hygiene punishment treatment program appears to be an immediate, effective, enduring, and humane method of treating the non-life-threatening rumination of retarded individuals.
