Dilated cardiomyopathy (DCM) is a progressive myocardial disorder characterized by impaired cardiac contraction and ventricular dilation. However, some patients with DCM improve when experiencing left ventricular reverse remodeling (LVRR). Currently, the detailed association between genotypes and clinical outcomes, including LVRR, particularly among children, remains uncertain. Pediatric patients with DCM from multiple Japanese institutions recorded between 2014 and 2023 were enrolled. We identified their DCM-related genes and explored the association between gene variants and clinical outcomes, including LVRR. We included 123 pediatric patients (62 males; median age: 8 [1-51] months) and found 50 pathogenic variants in 45 (35.0%) of them. The most identified gene was MYH7 (14.0%), followed by RYR2 (12.0%) and TPM1 (8.0%). LVRR was achieved in 47.5% of these patients. The left ventricular ejection fraction remained unchanged (31.4% to 39.8%, P = 0.1913) in patients with sarcomere gene variants and in those with non-sarcomere gene variants (33.4% to 47.8%, P = 0.0522) but significantly increased in those without gene variants (33.6% to 54.1%, P < 0.0001). LVRR was not uniform across functional gene groups. Hence, an individualized gene-guided prediction approach may be adopted for children with DCM.

Background

Cardiosphere‐derived cell (CDC) infusion was associated with better clinical outcomes at 2 years in patients with single ventricle heart disease. The current study investigates time‐to‐event outcomes at 8 years.

 Methods and Results

 This cohort enrolled patients with single ventricles who underwent stage 2 or stage 3 palliation from January 2011 to January 2015 at 8 centers in Japan. The primary outcomes were time‐dependent CDC treatment effects on death and late complications during 8 years of follow‐up, assessed by restricted mean survival time. Among 93 patients enrolled (mean age, 2.3±1.3 years; 56% men), 40 received CDC infusion. Overall survival for CDC‐treated versus control patients did not differ at 8 years (hazard ratio [HR], 0.60 [95% CI, 0.21–1.77]; P =0.35). Treatment effect had nonproportional hazards for death favoring CDCs at 4 years (restricted mean survival time difference +0.33 years [95% CI, 0.01–0.66]; P =0.043). In patients with heart failure with reduced ejection fraction, CDC treatment effect on survival was greater over 8 years (restricted mean survival time difference +1.58 years [95% CI, 0.05–3.12]; P =0.043). Compared with control participants, CDC‐treated patients showed lower incidences of late failure (HR, 0.45 [95% CI, 0.21–0.93]; P =0.027) and adverse events (subdistribution HR, 0.50 [95% CI, 0.27–0.94]; P =0.036) at 8 years.

 Conclusions

By 8 years, CDC infusion was associated with lower hazards of late failure and adverse events in single ventricle heart disease. CDC treatment effect on survival was notable by 4 years and showed a durable clinical benefit in patients with heart failure with reduced ejection fraction over 8 years.

Controlling pulmonary blood flow in patients who have undergone Norwood palliation, especially early postoperatively, is challenging due to a change in the balance of systemic and pulmonary vascular resistance. We applied a combination therapy of clipping and balloon angioplasty for right ventricle-pulmonary artery (RV-PA) shunt to control pulmonary blood flow, but the influence of the combination therapy on the PA condition is uncertain. Retrospectively analysis was conducted of all infants with hypoplastic left heart syndrome who had undergone Norwood palliation with RV-PA shunt at Okayama University Hospital from January 2008 to September 2022. A total of 50 consecutive patients underwent Norwood palliation with RV-PA shunt in this study period. Of them, 29 patients underwent RV-PA shunt flow clipping, and the remaining 21 had unclipped RV-PA shunt. Twenty-three patients underwent balloon angioplasty for RV-PA shunt with clips. After balloon angioplasty, oxygen saturation significantly increased from 69 (59-76)% to 80 (72-86)% (p < 0.001), and the narrowest portion of the clipped conduit significantly improved from 2.8 (1.8-3.4) to 3.8 (2.9-4.6) mm (p < 0.001). In cardiac catheterizations prior to Bidirectional cavo-pulmonary shunt (BCPS), there were no significant differences in pulmonary-to-systemic flow ratio (Qp/Qs), ventricular end-diastolic pressure, Nakata index, arterial saturation, mean pulmonary artery pressure and pulmonary vascular resistance index. On the other hand, in Cardiac catheterizations prior to Fontan, Nakata index was larger in the clipped group (p = 0.02). There was no statistically significant difference in the 5-year survival between the two groups (clipped group 96%, unclipped group 74%, log-rank test: p = 0.13). At least, our combination therapy of clipping and balloon angioplasty for RV-PA shunt did not negatively impact PA growth. Although there is a trend toward better but not statistically significant difference in outcomes in the clipped group compared to the non-clipped group, this treatment strategy may play an important role in improving outcomes in hypoplastic left heart syndrome.

OBJECTIVES: There is limited information on long-term outcomes and trajectories of ventricular and valvular functions in patients with congenitally corrected transposition of the great arteries after anatomic repair according to the operative strategy with a median follow-up period of more than 10 years. METHODS: Twenty-nine patients who underwent anatomic repair in Okayama University Hospital between January 1994 and December 2020 were reviewed. Outcomes were compared between patients who underwent a double switch operation (DS group) and patients with an atrial switch with a Rastelli operation (Rastelli-Senning/Mustard group). RESULTS: Fifteen (52%) were in the DS group and 14 (48%) were in the Rastelli-Senning/Mustard group. The median follow-up period after anatomic repair was 12.7 (interquartile range 4.2-18.8) years. There were 3 (10%) early deaths and 3 (10%) late deaths. Survival rates for the entire cohort at 10 and 20 years were 86% and 71%, respectively, and were not different between the 2 groups. Using competing risk analysis, risks of heart failure, cardiac rhythm device implantation and atrial arrhythmia showed no significant differences between the 2 groups, whereas risk of reoperation was higher in the Rastelli-Senning/Mustard group than that in the DS group. Four patients after a DS operation and 1 patient after a Rastelli technique developed more than moderate aortic regurgitation. CONCLUSIONS: During a median follow-up period of more than 10 years, mortality rate and ventricular and valvular functions after anatomic repair were acceptable, though the incidences of late complications were relatively high, especially in the Rastelli-Senning/Mustard group.

BACKGROUND: Children with a congenital heart disease (CHD) are at a higher risk of developing epilepsy than the general population, but detailed characteristics of CHD-associated epilepsy have not been clarified. The purposes of this study were to determine the risk factors for developing epilepsy associated with CHD and to elucidate the characteristics of such epilepsy. METHODS: We performed a retrospective cohort study based on medical records of pediatric patients with CHD who were born between January 2006 and December 2016, underwent cardiac surgery at Okayama University Hospital, and were followed up until at least age three years. Multivariate logistic regression analysis was used to determine factors particularly associated with epilepsy occurrence. In patients who developed epilepsy, clinical data on seizure characteristics were further investigated. RESULTS: We collected data from 1024 patients, and 41 (4.0%) developed epilepsy. The presence of underlying disease (odds ratio [OR]: 2.413; 95% confidence interval [CI]: 1.150 to 4.883) and the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery score category 2 (OR: 4.373; 95% CI: 1.090 to 29.150) and category 5 (OR: 10.385; 95% CI: 1.717 to 89.016) were significantly related to epilepsy occurrence. Of the 41 patients with epilepsy, 15 (including nine with hypoplastic left heart syndrome) had focal impaired awareness seizures specified as autonomic seizures with vomiting, which tends to escape detection. CONCLUSIONS: We clarified the risk factors for developing epilepsy in children with CHD. We also found that autonomic seizure with vomiting is an important symptom in these children.
