Abstract
Whereas bicaval technique is an effective surgical method, standard bicaval technique for younger age and donor/recipient caval mismatch was reported to have a risk of superior vena caval obstruction. Between 2016 and 2019, three patients with dilated cardiomyopathy aged 10 years or younger underwent orthotropic heart transplantation with modified bicaval technique at our institute. Donor/recipient body weight and height ratios were 2.36, 0.77, and 2.61 and 1.37, 0.94, and 1.51, respectively. All patients were preoperatively supported by a left ventricular assist device: Excor Pediatric in two patients and Jarvik 2000 in one. Duration of LVAD support was 180, 238, and 220 days. One patient required revision of pulmonary anastomosis during the operation; accordingly, the chest was closed 3 days later. There was no mortality. Caval obstructions were not observed. Three months after the operation, tricuspid regurgitation was mild in two patients and trivial in one.

Abstract
BACKGROUND Although adverse effects of phrenic nerve palsy (PNP) on early Fontan circulation have been reported, detailed late impact remains unclear. METHODS Of 218 patients undergoing extracardiac total cavopulmonary connection between 1995 and 2008, 160 who all underwent cardiac catheter examination, spirometry, and exercise capacity testing 10 years after the operation were enrolled. The cohort was divided into 2 groups: with (N = 21) or without PNP (control group, N = 139). The patients with PNP were further divided into the recovered PNP group (n = 10) and the persistent PNP group (n = 11). All but 2 patients who developed PNP (90.9%) underwent diaphragmatic plication. There was no difference in hemodynamic indices at pre-Fontan evaluation among the three groups. RESULTS Ten years after the Fontan procedure, the averaged forced vital capacity was 81% ± 18% of predicted in the control group, 86% ± 17% in the recovered PNP group, and 56% ± 12% in the persistent PNP group (P < .001). Peak oxygen consumption was linearly correlated to the forced vital capacity (r = 0.222, P = .009). There was no significant difference in the peak oxygen consumption between groups. Significant veno-venous collaterals into the diaphragm from lower body to pulmonary vein(s) or atria more frequently developed in patients who underwent diaphragmatic plication compared with those who did not (P < .001). CONCLUSIONS Persistent PNP resulted in reduced forced vital capacity; however, its influence on exercise intolerance could not be identified. Diaphragmatic plication should be reserved for patients who experience clinically significant respiratory or hemodynamic sequelae of PNP.

Abstract
OBJECTIVES To review the long-term surgical outcomes of ventricular septation for double-inlet left ventricle and reconsider the possibility of ventricular septation as an option of surgical treatments. METHODS Between 1978 and 1994, 22 patients with double-inlet left ventricle underwent ventricular septation. The mean age at operation was 5.3 years (range 0-22 years). Follow-up was carried out in 20 of 22 patients (91%) and the mean follow-up period was 14.7 years (range 0-39 years). RESULTS Actuarial survival and reoperation-free survival rates at 30 years were 49% and 21%, respectively. To date, 8 patients have been followed up. Among them, atrioventricular valve replacement and permanent pacemaker were required in 4 and 7 patients, respectively. Late cardiac catheter examination at 25.5 years after surgery showed that the median cardiac index was 2.6 l/min/m2 (range 2.1-3.4 l/min/m2), left ventricular end-diastolic pressure was 7 mmHg (range 4-11 mmHg), left ventricular ejection fraction was 50% (range 27-63%), right ventricular ejection fraction was 53% (range 31-66%) and central venous pressure was 6 mmHg (range 4-11 mmHg). At the latest follow-up, the New York Heart Association Functional Classification was I for 5 patients, II for 2 patients and III for 1 patient. The median peak oxygen uptake was 52.9% (range 44.1-93.5%). CONCLUSIONS Some patients with double-inlet left ventricle were able to maintain low central venous pressure and a sufficient cardiac index long after ventricular septation. Although the single ventricle strategy remains a first-line treatment, ventricular septation can be a surgical treatment option.

Abstract
OBJECTIVES The objective of this study was to assess the utility of 3D printed heart models of congenital heart disease for preoperative surgical simulation. METHODS Twenty patient-specific 3D models were created between March 2015 and August 2017. All operations were performed by a young consultant surgeon who had no prior experience with complex biventricular repair. All 15 patients with balanced ventricles had outflow tract malformations (double-outlet right ventricle in 7 patients, congenitally corrected transposition of great arteries in 5, transposition of great arteries in 1, interrupted aortic arch Type B in 1, tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries in 1). One patient had hypoplastic left heart complex, and the remaining 4 patients had a functional single ventricle. The median age at operation was 1.4 (range 0.1-5.9) years. Based on a multislice computed tomography data set, the 3D models were made of polyurethane resins using stereolithography as the printing technology and vacuum casting as the manufacturing method. RESULTS All but 4 patients with a functional single ventricle underwent complete biventricular repair. The median cardiopulmonary bypass time and aortic cross-clamp time were 345 (110-570) min and 114 (35-293) min, respectively. During the median follow-up period of 1.3 (0.1-2.5) years, no mortality was observed. None of the patients experienced surgical heart block or systemic ventricular outflow tract obstruction. CONCLUSIONS Three-dimensional printed heart models showed potential utility, especially in understanding the relationship between intraventricular communications and great vessels, as well as in simulation for creating intracardiac pathways.

Abstract
OBJECTIVES To assess the feasibility of hybrid Stage I palliation consisting of bilateral pulmonary artery bandings and ductal stenting for patients with 2 ventricular cavities and hypoplastic left heart structures. METHODS Eleven consecutive patients who underwent hybrid Stage I palliation between 2010 and 2017 were enrolled. The diagnoses were interrupted aortic arch/coarctation of the aorta, ventricular septal defect and significant left ventricular (LV) outflow tract obstruction in 5 patients, critical aortic stenosis and reduced LV contraction in 3 patients and hypoplastic left heart complex in 3 patients. RESULTS The median age at definitive surgery was 12 months (range 6-22 months). During the mean follow-up period of 24 months (range 9-83 months) following the definitive surgery, there was 1 death. Two patients with interrupted aortic arch/coarctation of the aorta did not undergo the Yasui operation but underwent arch repair and ventricular septal defect closure after the growth of the aortic valve and LV outflow tract. For 2 of the 3 patients with critical aortic stenosis, biventricular repair was performed. Of the 3 patients with hypoplastic left heart complex, 2 patients showed growth of the mitral valve and left ventricle following LV rehabilitation by balloon pulmonary artery dilatation or surgical debanding of the banded pulmonary arteries and subsequently underwent biventricular repair, which resulted in 1 death. CONCLUSIONS Hybrid Stage I palliation would be a safe and beneficial treatment for patients with 2 ventricles, as a bridge to decide whether and how to achieve a biventricular repair and whether it should be preceded by a preliminary LV rehabilitation.

Abstract
Objective: Surgical outcomes of biventricular repair for hearts with hypoplastic left ventricle with congenital mitral valve stenosis are described. Serial changes of left ventricular geometry and clinical features after biventricular repair were reviewed. Methods: Eight patients with hypoplastic left ventricle and congenital mitral valve stenosis who underwent first surgical intervention for biventricular circulation in neonatal or infantile period between 2001 and 2014 comprise the study population. Serial change in left ventricular end-diastolic diameter, left ventricular mass index, and relative wall thickness after biventricular repair were evaluated by two-dimensional echocardiography. Results: The median Z-scores of left ventricular end-diastolic diameter and mitral valve diameter before the first surgical intervention were −3.0 (range, −4.8 to −2.0) and −1.0 (−2.9 to 2.1), respectively. Mitral valves were surgically treated in five patients; they were replaced in two and repaired in three patients. Left ventricular end-diastolic diameter Z-score at five years after biventricular repair was 0.1 (−3.0 to 1.0), which was significantly larger than before first surgical intervention ( P = .005). Left ventricular mass index, on the other hand, did not change, but relative wall thickness significantly decreased ( P = .009). Postoperative catheter study showed pulmonary hypertension with high left ventricular end-diastolic pressure in more than half of survivors. Conclusions: Left ventricle increased in size after the biventricular repair with appropriate mitral valve procedures before progression of pulmonary hypertension. Left ventricular mass, however, did not accompany the increase. Some patients may have suffered from mild, but certain restrictive left ventricular physiology and subsequent pulmonary hypertension as the result of abnormal remodeling process of the myocardium.

Abstract
For neonates with right atrial isomerism (RAI), functional single ventricle (f-SV), and obstructive total anomalous pulmonary venous connection (TAPVC), primary TAPVC repair (TAPVCR) has a poor outcome. At our hospital, the survival rate at 1 year of such neonates undergoing primary TAPVCR between 1999 and 2010 (TAPVCR group) was 30% (3/10). Most deceased cases suffered from capillary leak syndrome and unstable pulmonary resistance after the surgeries. We sought to determine whether less invasive primary draining vein stenting (DVS) improved the outcome of these neonates. We investigated outcomes in consecutive nine such neonates (median gestational age 38 weeks, birth weight 2.8 kg, females 4) who underwent primary DVS with 6-mm-diameter Palmaz® Genesis® stents at our hospital between 2007 and 2017 (DVS group). Eight patients underwent subsequent surgeries to adjust the pulmonary flow after decreased pulmonary resistance. The survival rate at 1 year after the first interventions in the DVS group improved to 77% (7/9), although there was a difference between the interventional eras of the two groups. Of the seven patients who underwent multiple stent redilations with a larger balloon or additional stenting in other sites until the next stage of surgery at a median age of 8 months, four received a bidirectional Glenn (BDG) shunt and TAPVCR and three underwent TAPVCR, with two of those cases reaching BDG. Less invasive primary DVS improved the outcome of neonates with RAI, f-SV, and obstructive TAPVC, with many reaching BDG. Patient selection to advance toward Fontan is thought to further improve the outcome.

Abstract
An 11-month-old girl with an unbalanced atrioventricular septal defect, coarctation of the aorta and an interrupted inferior vena cava with hemiazygos continuation post-surgical status of coarctation repair and pulmonary artery banding underwent a Kawashima operation. Severe hypoxia occurred immediately after she was weaned from cardiopulmonary bypass, which was successfully resolved by the ligation of the hemiazygos vein. Postoperative enhanced computed tomography detected significant venovenous malformation from the hemiazygos vein to the left renal vein.

Abstract
The purpose of the study is to analyze the impact of hybrid stage 1 palliation on right ventricular myocardial pathology in hypoplastic left heart syndrome. Sufficient amount of right ventricular biopsies could be obtained from 16 of 32 patients who underwent Norwood operation between 2007 and 2013. Histopathological findings of right ventricle in patients who underwent primary Norwood operation (primary group, n = 5), patients with aortic atresia (HS1P AA group, n = 6) or aortic stenosis (HS1P AS group, n = 5) who underwent staged Norwood palliation following hybrid stage 1 palliation were compared. To eliminate the influence of right ventricular pressure afterload, right ventricular biopsies were obtained from patients with truncus arteriosus communis (TAC group, n = 6) at total correction. The percentage of myocardial fibrosis was significantly higher in both HS1P groups than in TAC group; moreover, it was significantly higher in HS1P AA group than in primary group. Capillary vascular density was significantly lower in all hypoplastic left heart syndrome groups than in TAC group. At the sub-endocardial layer, collagen type I/III ratios were higher in HS1P AA group than in other hypoplastic left heart syndrome groups. The proportions of N-cadherin immunolocalized to myocyte termini were lower in all hypoplastic left heart syndrome groups than in TAC group. Right ventricle in hypoplastic left heart syndrome showed more significant ischemic change and myocardial immaturity than that in truncus arteriosus communis. Hybrid stage 1 palliation for aortic atresia would be a risk factor for further right ventricular myocardial ischemia.

Abstract
Background The surgical treatment of congenital heart disease is reported to be associated with a high prevalence of scoliosis, although the detailed etiology is unknown. Surgical interventions involving the rib cage are considered to increase the risk of scoliosis. However, whether the cardiac condition or the procedure performed makes patients more susceptible to the development of spinal deformity is controversial. Methods The present study included 483 patients who underwent surgery for the treatment of congenital heart disease with use of procedures involving the immature rib cage (sternotomy and/or thoracotomy) during the first year of life, followed by the evaluation of standing chest radiographs at ≥10 years of age. Patients with congenital spinal deformity and potential neuromuscular disease were excluded. The prevalence of and predictive factors for scoliosis were evaluated. The presence of scoliosis (Cobb angle ≥10° to <20°, ≥20° to <30°, ≥30° to <45°, ≥45°), the convex side of the curve, and the location of the curve were evaluated radiographically. Potential predictive factors that were analyzed included the age at the time of surgery, surgical approach, use of cardiopulmonary bypass, postoperative heart failure and/or cyanosis, New York Heart Association (NYHA) class, cardiomegaly, and age at the time of radiography. Results The mean age at the time of surgery was 112 days, and the mean age at the time of radiography was 14.4 years. The prevalence of scoliosis was 42.4%, and the prevalences of ≥10° to <20°, ≥20° to <30°, ≥30° to <45°, and ≥45° scoliosis were 31.7%, 5.8%, 2.5%, and 2.5%, respectively. Three patients underwent surgery for the treatment of progressive scoliosis. Multivariate analysis indicated that the predictive factors were female sex, left thoracotomy, bilateral thoracotomy, NYHA class, and age at the time of radiography for ≥10° scoliosis; cardiomegaly, NYHA class, and age at the time of radiography for ≥20° scoliosis; cardiomegaly, number of surgical procedures, and age at the time of radiography for ≥30° scoliosis; and cardiomegaly for ≥45° scoliosis. Age at the time of radiography was a predictor of <45° scoliosis; however, the relative association was small. Conclusions Surgery for the treatment of congenital heart disease during the first year of life was associated with a high prevalence of scoliosis (≥40%). While female sex was one of several predictors of ≥10° scoliosis, cardiomegaly was the sole predictor of ≥45° scoliosis. Level of Evidence Prognostic Level IV.

Abstract
A 6-year-old girl with unbalanced atrioventricular septal defect, hypoplastic right ventricle, and severe common atrioventricular valve regurgitation developed patient-prosthetic mismatch. At 6 months old, she underwent primary one and one-half ventricle repair and replacement of left side atrioventricular valve. A catheter examination showed that her right ventricular end-diastolic volume increased from 39.4 mL/m2 1 year after to 70 mL/m2 3.5 years after the previous surgery. Thus, at the timing of redo left side atrioventricular valve replacement, she was converted successfully to biventricular circulation. The postoperative course was uneventful, and the right atrial pressure was 7 mm Hg before discharge.

Abstract
A 5-day-old neonate with coarctation of the aorta, hypoplastic aortic arch, large apical muscular ventricular septal defect, and patent ductus arteriosus developed pulmonary over-circulation and systemic hypoperfusion underwent bilateral pulmonary artery banding through median sternotomy as a part of hybrid stage I palliation. At operation, left atrial diverticulum with gigantic thrombus formation at the base of the left atrial appendage was incidentally detected by intraoperative direct echocardiography, and therefore, was successfully resected with the whole thrombus inside it without use of cardiopulmonary bypass. Histopathological finding was compatible with diverticulum. The patient was free from atrial arrhythmia and recurrent thrombus formation.

Abstract
BACKGROUND Since August 2015, the pediatric ventricular assist device (VAD), Berlin Heart EXCOR®, has been accepted for use in Japan.Methods and Results:Between August 2015 and July 2016, 4 pediatric patients with endstage heart failure underwent LVAD implantation with the EXCOR®device. The median age and body weight at operation were 8 months and 4.8 kg. During a median follow-up of 7.3 months (range, 5.0-10.3), all patients survived. Two patients went on to heart transplantation and the remaining 2 are on a waiting list with stable hemodynamics. CONCLUSIONS The early outcomes of the Berlin Heart EXCOR®pediatric VAD were satisfactory. (Circ J 2016; 80: 2552-2554).
