A 5-day-old neonate (body weight=2.4 kg) with coarctation of the aorta and critical aortic stenosis underwent an interventional balloon valvuloplasty for aortic stenosis. During the intervention, cardiac arrest occurred due to injury of the right carotid artery by the guide wire. An extracorporeal membrane oxygenator (ECMO) was applied. After 1 day's support, total surgical correction was achieved; however, in the immediate postoperative period, cardiac function was severely depressed. We applied a bi-ventricular assist device (bi-VAD) instead of an ECMO and we were able to wean the patient off the bi-VAD device after 3 days' support. The patient was discharged without severe complications.

Extracorporeal membrane oxygenation (ECMO) provides mechanical cardiopulmonary support and has been used for children with severe respiratory failure, intractable heart failure, sepsis, pulmonary hypertension, and as a bridge to heart transplantation. There have been few reports of the use of ECMO to provide cardiac support in children with low cardiac output as a result of arrhythmias. We report the case of a 15-year-old female with circulatory collapse due to refractory ventricular arrhythmia after one and a half repair in Ebstein's anomaly, who was successfully resuscitated using ECMO.

The patient was an eight-year-old female. She was diagnosed as dilated cardiomyopathy. She was supported with bi-ventricular assist because of heart failure for 15 days. After 7 days, she was suffered from prerenal type ARF and support with continuous veno-veno hemodyalisis(CVVHD). And then heart transplantation was performed, heart donor's blood type was A. Immune suppressants were used after due consideration for renal toxicity. ARF was resolved on post operative $14^{th}$ day. She was discharged on post operative $52^{nd}$ day without any specific post operative complication. She has been followed up without any immune rejection reaction upto 14 months.

The reported incidence of postcardiotomy cardiogenic shock not responding to conventional therapy is still 0.1 to 0.8%. For this group of patients, more aggressive form of circulatory support must be employed. Centrifugal pumps are a ventricular assist device most commonly used on this purpose, due to low cost and easy availability. Currently, however, clinical experience of centrifugal pumps as a ventricular assist device is rarely reported in Korea. From January 1992 to January 1996, 2986 patients underwent cardiac operations on cardiopulmonary bypass at Seoul National University Hospital. Refractory postcardiotomy cardiac failure requring ventricular support with a Biomedicus centrifugal pump developed in ten of these patients. There were eight men and two women, ranged in age from nine years to 77 years with a mean of 50$\pm$20 years. The primary surgical procedures consisted of isolated coronary revascularization in four patients, combined coronary revascularization and aortic valve replacement in two, aortic dissection repair in two, pulmonary embolectomy in one, and heart transplantation in one. Of the ten patients, five had left ventricular assistance, one had right ventricular assistance, and four had biventricular assistance. Duration of ventricular assistance ranged from 24 to 175 hours, with a mean of 76$\pm$51 hours. Seven patients were weaned from ventricular assistance, and four of them discharged. The causes of death for nonsurvivors were progressive cardiac failure in two patients and multiorgan failure, intractable ventricular fibrillation, irreversible brain injury, and mechanical problem, respectively, in the other four. Survival was not predicted by time on cardiopulmonary bypass, aortic cross-clamp time, or duration of ventricular support. Major complications included bleeding(7), renal failure(6), infection(3) and neurologic complication(2). These results indicate that a centrifugal pump can provide reasonably satisfactory short-term circulatory support.
