    Notes: Abstract To investigate whether pulsatile perfusion affects postoperative edema, we examined weight, total body water (TBW), and extracellular fluid (ECF) following cardiopulmonary bypass (CPB) in dogs using three different perfusion systems. Fourteen dogs were divided into three groups differing only in the perfusion system used: Sarns nonpulsatile and pulsatile roller pumps and a University of Texas pulsatile pump. Weight, TBW, and ECF were measured preoperatively and on postoperative days (POD) 1, 3, and 7. No significant differences were seen in body weight, TBW, or ECF between groups. Body TBW (percent of body weight) rose significantly (P=0.005) to 72% on POD 3 and 7. ECF (percent of body weight) rose to 58% by POD 7 (P=0.008). These three perfusion systems produced no differences in the pattern of postoperative body fluid distribution after CPB, suggesting that there is no advantage to pulsatile perfusion for the purpose of decreasing postoperative edema.

    Notes: Summary To determine whether preoperative psychological testing in children with cyanotic heart disease could provide an accurate estimate of adult performance, we studied 21 subjects (mean age, 30.3±4.8 years) who had undergone surgical repair for tetralogy of Fallot between 1958 and 1966 (mean age, 8.7±3.9 years); 17 received childhood preoperative testing (mean age, 8.9±4.2) and four had early postoperative testing. Follow-up psychological tests administered in 1983 included Wechsler Adult Intelligence Scale Revised, Jackson Personality Research Form E, Rosenberg Self-Esteem Scale, and a questionnaire-interview on educational, occupational, and psychosocial status. Adult IQ (x=93.4±15.6) and child IQ (x=97.5±14.6) scores were highly correlated (r=0.87,p〈0.01), revealing considerable stability across 22.3±2.2 years. On 17 of 22 Jackson personality scales, the subjects (S) were within the normal range. Scoring below the 16th percentile were 11/21 S on intellectual curiosity, 9/21 S on adaptability to change, and 8/21 S on leadership skills. Scoring above the 84th percentile were 8/21 S on harm avoidance and 8/21 S on giving nurturance to others. Univariate one-way ANOVAs indicated that those subjects with the higher IQ scores had the higher incomes, job levels, and educational attainments. We conclude that the results of perioperative psychological testing in children with tetralogy of Fallot are congruent with postoperative adult intellectual and psychosocial status.

    Notes: Summary The Wolff-Parkinson-White syndrome, as originally described, includes palpitations, tachycardia, and an abnormal electrocardiogram (short PR interval and wide QRS complex). The clinical manifestations are dependent upon a reentrant tachycardia supported by an accessory connection bridging the atrioventricular junction and frequently appear during the first two decades of life. Palpitations are the usual symptoms; less frequently, severe symptoms, such as syncope and sudden death, may result from very rapid atrioventricular conduction across the accessory connection during atrial fibrillation. We report the surgical management of 30 young patients with this syndrome, including 6 with life-threatening tachycardia. Surgical interruption of the accessory connection(s) was curative in 90% (27/30) of the patients; life-threatening symptoms were eliminated in the other three. Based on the limited knowledge of the natural history of the Wolff-Parkinson-White syndrome, the individual patient symptoms, and the electrophysiologic properties of each patient's accessory pathway(s), an algorithm is presented outlining the treatment options. This experience strongly suggests that surgical treatment of the Wolff-Parkinson-White syndrome is safe, effective, and possibly the preferred treatment for this disorder in selected young symptomatic patients.
