Abstract
Isolated ventricular non-compaction is a rare cardiomyopathy associated with left heart failure, severe arrhythmias and thromboembolism. We report about our interdisciplinary strategy in a patient with severe isolated ventricular non-compaction cardiomyopathy scheduled for caesarean section in general anaesthesia. Monitoring included placement of an arterial line, a central venous catheter and a pulmonary artery catheter with pacing option. Small introducer gates were placed in the femoral artery and vein to facilitate quick percutaneous institution of extracorporeal life support via extracorporeal membrane oxygenation in case of acute cardiac failure refractory to medical treatment. Inotropic pharmacological therapy with 3 µg/kg/min dobutamine and 0.25 mg/kg/min milrinone was started before surgery. Induction of general anesthesia and rapid sequence intubation was performed with an analgesic dose of 0.5 mg/kg S ketamine, 0.25 mg/kg etomidate and 5 mg rocoronium followed by 1.5 mg/kg succinylcholine. This regimen provided completely stable hemodynamics in this critical period until delivery of the child and continuation of anaesthesia with continuous infusion of propofol and remifentanyl. The current strategies, particularly the preparation for femoro-femoral extracorporeal membrane oxygenation, may be considered in similar cases with a high risk of acute cardiac decompensation which may be refractory to medical treatment. Anaesthesiologist involved in performing caesarean section in women with complex cardiac disease, should encompass extracorporeal membrane oxygenation standby in management of the perioperative period.

Abstract
Kawasaki disease (KD), also called mucocutaneous lymph node syndrome, is an acute, self-limiting, small-vessel vasculitis with an unknown cause that affects children between the ages of 6 months and 5 years. It is the most common cause of acquired coronary artery disease in childhood. Acute myocardial infarction and coronary artery aneurysm are major complications. We present a cohort of patients with KD who were followed up and treated in the Heart Center, North Rhine-Westphalia. Included is a review of important relevant items common to cases of KD, such as clinical data and management, including medical management of the acute condition and the diagnosis and management of coronary vasculitis and aneurysms as well as the application of coronary artery bypass grafting (CABG) in those conditions. Between January 2002 and January 2006, we evaluated the findings and characteristics of 18 pediatric patients with a history of KD and their long-term outcome. The acute illness occurred between the ages of 4 months and 14 years of age. Anomalies of the coronary arteries were found in 6 patients ranging in age from 5 months to 10 years. One patient had acute myocardial infarction; another underwent CABG after 5 years from disease onset at the age of 15 years. Kitamura operation was performed successfully. The other patients are still under observation.Coronary artery aneurysms and stenosis requiring surgery are rare in KD; nevertheless, CABG is the standard therapy when myocardial ischemia is detected. Kitamura operation provides good growth potential and long-term graft patency.

Abstract
OBJECTIVES To examine whether the line dividing the septum into two layers is found consistently by conventional echocardiography and to evaluate functional differences in the right and left side of the septum in terms of wall thickening, strain rate, and strain imaging. DESIGN In a systematic study in 30 normal subjects, M mode and Doppler myocardial imaging data from the interventricular septum (IVS) were recorded. Velocity curves, regional strain rate, and strain profiles were obtained. Systolic deformation (wall thickening, radial and longitudinal strain rate, and strain) of both sides were assessed. Furthermore, three patients with one sided abnormalities were studied. RESULTS A bright echo consistently segmented the IVS into a left and right part. In this normal population radial deformation was different for the left and right side of the septum (mean (SD) wall thickening on the left, 49 (46)%, and on the right, 17 (38)%; strain rate on the left, 3.8 (0.6) 1/s, and on the right, 2.1 (1.9) 1/s; strain on the left, 41 (17)%, and on the right, 22 (14)%), whereas longitudinal deformation was found to be similar (strain rate on the left, -2.2 (0.7) 1/s, and on the right, -2.0 (0.6) 1/s; strain on the left, -28 (12)%, and on the right, -25 (12)%). The presented clinical examples show that abnormalities can be strictly limited to one layer. CONCLUSIONS Differential radial deformation and knowledge of fibre architecture showing an abrupt change in the middle of the septum, together with the clinical cases, suggest the septum to be a morphologically and functionally bilayered structure potentially supplied by different coronary arteries.

Abstract
We assessed the cardiac findings in Duchenne muscular dystrophy (DMD) and Becker-Kiener muscular dystrophy (BMD) patients in the large outpatient group of our single-center institution. The analysis included the revision of patient records (retrospectively) and current echocardiography, electrocardiogram (ECG), and Holter ECG data (prospectively). Reduced left ventricular fraction shortening (FS) < 25% was found in 24% of all patients (50 DMD, 12.1 +/- 4.7 years: 20 BMD, 17.1 +/- 8.5 years). Median age of onset of FS < 25% was 16.8 +/- 1.0 in DMD and 30.4 +/- 3.4 in BMD; (p < 0.05). Holter ECG in DMD demonstrated sinus tachycardia in 26% deprivation of circadian rhythm in 31%, and reduced heart rate variability in 51%. For these reasons, we recommend carrying out echocardiography annually in DMD and BMD > 10 years. Because the rate of disturbances in the cardiac autonomic nervous system is high in DMD, we also recommend Holter ECG annually. Further investigation should be conducted to determine if treatment with ss-blockers and ACE inhibitors in combination reduces cardiac autonomic nervous imbalance, thus improving patient outcome in DMD.

Abstract
OBJECTIVES To assess the impact of balanced ultrafiltration and peritoneal dialysis (PD) on plasma and urinary cytokines and renal dysfunction after cardiopulmonary bypass (CPB) surgery in newborns and infants. METHODS Twenty-three newborns and infants weighing less than 7 kg and scheduled for operation on congenital malformation were enrolled in this descriptive open clinical study. All patients received conventional ultrafiltration in the CPB rewarming period. Eleven newborns underwent Tenckhoff-catheter implantation in the operation theatre as a routine institutional procedure and received PD after admission to the ICU (the PD [+] group). No PD was used in another 12 patients (the PD [-] group). Interleukins (IL) 6 and 8 were measured four times pre- and post-operatively. Kidney function was assessed by creatinine clearances and urine protein and enzyme analyses. RESULTS All patients had an uneventful clinical course. Age (10+/-2 days, PD [+] vs. 96+/-19 days, PD [-]), CPB duration (215+/-23 vs. 143+/-20 min), and degree of hypothermia (26+/-1.3 vs. 31+/-0.1 degrees C) differed significantly between the groups. Age, CPB duration and ultrafiltration influenced post-operative IL-levels in an analysis of variance. While there were few differences immediately after the end of ultrafiltration, post-operative levels of IL-6 and IL-8 were higher and more sustained in the newborns (PD [+]) than in the older infants (PD [-]). The median amount of IL-6 and IL-8 removed by ultrafiltration came to 28 and 59% compared to the amount of IL-6 and IL-8 remaining in the blood at the end of CPB. IL-clearance by ultrafiltration was more than 1000-fold and by PD more than 100-fold as effective as IL-clearance by the kidney. While the kidneys showed an unselective mixed glomerular and tubular pattern of injury, during CPB higher serum IL-concentrations correlated with lower urinary IL-clearances in both study groups. CONCLUSIONS Ultrafiltration and PD are highly effective in removing proinflammatory cytokines. Impaired kidney function was associated with proinflammatory IL-serum concentrations. Thus, we raise the hypothesis that glomerular-filtered proinflammatory ILs damage the proximal tubular cells of the kidney in newborns and infants, thus contributing to post-operative renal dysfunction. Conversely, we conclude that removing proinflammatory ILs by ultrafiltration and PD acts renoprotectively. A future prospective randomised study could demonstrate whether this can indeed improve clinical outcome.

Abstract
Superior vena cava (SVC)-thrombosis in a neonate after cardiac surgery is difficult to manage. This article reports on the successful treatment of SVC-syndrome in a critically ill newborn by surgical thrombectomy and reinsertion of the SVC in the right atrial appendage in the beating heart.
