  • We describe a case of successful extracorporeal membrane oxygenation(ECMO) in a small infant with cardiopulmonary resuscitation(CPR) failure after an open heart surgery. A 35-day-old male infant weighing 4.4 kg who had congestive heart failure and pulmonary hypertension underwent patch closure of ventricular septal defect without any intraoperative event. Postoperative course was unremarkable in the intensive care uint for about 5 hours before the junctional ectopic tachycardia developed. Sudden cardiac decompensation with bradycardia occurred about 50 minutes after the development of junctional ectopic tachycardia. He was put on ECMO by arterial cannulation at the ascending aorta and by venous cannulation at the right atrial appendage after 4 hours' CPR. The hemodynamics were stable with enough urine output during ECMO. He was weaned from ECMO 38.5 hours after initiation. Delayed sternal closure was attempted. He was extubated on postoperative day 7 and discharged home on postoperative day 21 without any neurologic sequelae.

  • 50 days old, 4.5kg male patient was admitted at department of pediatrics due to congenital heart disease with congestive heart failure. The echocardiographic finding was perimembranous type ventricular septal defect. The patient underwent open heart surgery for patch closure of VSD. Immediately postoperatively, junctional ectopic tachycardia developed and the patient was in hemodynamically unstable state with decreased urine output. We used inotropics, digitalis and diuretics, however these treatments were not effective in recovering the unstable state. Therefore, we tried a mild hypothermic treatment(34℃). During the POD #2, mild hypothermia method was repeated four times. The junctional ectopic tachycardia was converted to normal sinus rhythm, hemodynamic state was stable, and urine output was increased. The patient was discharged at POD #8.

  • Mass electrocardiographic (ECG) examination was performed on 13,801 children (male 7,526 and female 6,275) of elementary and middle school in Taegu from May 1. 1986. to April 30. 1987. We read their ECG according to the "Pediatric Electrocardiography." The results were as following; The Incidence of ECG abnormality was 1.05%(male 1.3% and female 0.75%). Fifty eight children (0.42%) had atrial and ventricular hypertrophy; two right atrial hypertrophy, five left atrial hypertrophy, thirty five fight ventricular hypertrophy and sixteen left ventricular hypertrophy respectively. Ectopic beats occurred in 25 children (0.18%) ; They were atrial in 12 children, ventricular in 8 children and junctional in 5 children. There were 62 children (0.45%) of conduction disturbance ; They were first degree atrioventricular (A-V) block in 21 children, type I second degree A-V block in 1 child, A-V dissociation in 1 child, right bundle branch block in 36 children, left bundle branch block in 1 child and WPW syndrome in 2 children. Nonspecific ST, T changes and sinus tachycardia were found in 3 and one children respectively.

  • Background: Our objectives were to review our institutional early and midterm experience with primary tetralogy of Fallot (TOF) repair, and identify predictors of intensive care unit (ICU) morbidity. Methods: We analyzed perioperative and midterm follow-up data for all cases of primary TOF repair from 2001 to 2012. The primary endpoint was early mortality and morbidity, and the secondary endpoint was survival and functional status at follow-up. Results: Ninety-seven patients underwent primary repair. The median age was 4.9 months (range, 1 to 9 months), and the median weight was 5.3 kg (range, 3.1 to 9.8 kg). There was no early surgical mortality. The incidence of junctional ectopic tachycardia and persistent complete heart block was 2% and 1%, respectively. The median length of ICU stay was 6 days (range, 2 to 21 days), and the median duration of mechanical ventilation was 19 hours (range, 0 to 136 hours). By multiple regression analysis, age and weight were independent predictors of the length of ICU stay, while the surgical era was an independent predictor of the duration of mechanical ventilation. At the 8-year follow-up, freedom from death and re-intervention was 97% and 90%, respectively. Conclusion: Primary TOF repair is a safe procedure with low mortality and morbidity in a medium-sized program with outcomes comparable to national standards. Age and weight at the time of surgery remain significant predictors of morbidity.

  • Purpose : Early postoperative arrhythmias are a major cause of mortality and morbidity after open heart surgery in the pediatric population. We evaluated the incidence and risk factors of early postoperative arrhythmias after surgery of congenital heart disease. Methods : From January 2002 to December 2008, we retrospectively reviewed the medical records of the 561 patients who underwent cardiac surgery in Kyungpook National University Hospital. We analyzed patients' age and weight, occurrence and type of arrhythmia, cardiopulmonary bypass (CPB) time, aortic cross clamp (ACC) time, and postoperative electrolyte levels. Results : Arrhythmias occurred in 42 of 578 (7.3%) cases of the pediatric cardiac surgery. The most common types of arrhythmia were junctional ectopic tachycardia (JET) and accelerated idioventricular rhythm (AIVR), which occurred in 17 and 13 cases, respectively. The arterial switch operation (ASO) of transposition of the great arteries (TGA) had the highest incidence of arrhythmia (36.4%). Most cases of cardiac arrhythmia showed good response to management. Patients with early postoperative arrhythmias had significantly lower body weight, younger age, and prolonged CPB and ACC times ($P$<0.05) than patients without arrhythmia. Although the mean duration of ventilator care and intensive care unit stay were significantly longer ($P$<0.05), the mortality rate was not significantly different among the 2 groups. Conclusion : Early postoperative arrhythmias are a major complication after pediatric cardiac surgery; however, aggressive and immediate management can reduce mortality and morbidity.
