CTS is often found in conjunction with congenital heart diseases (CHD). Although slide tracheoplasty has demonstrated huge improvement in clinical outcomes of treating CTS and has recently emerged as the dominant surgical technique, some hospitals in Japan are still challenged by the amount of work required to manage and treat CTS cases. Generally, CTS in patients with CHD makes the condition more complex and severe due to the sensitive and crucial link between the pulmonary and systemic circulations, such as cardiopulmonary interaction. Therefore, acquiring sufficient knowledge on CTS is highly essential for the attending med-ical staff in pediatric cardiology. This article reviews and summarizes the clinical presentation and perioperative management of CTS, emphasizing its association with the CHD.","PeriodicalId":89701,"journal":{"name":"Nihon Shoni Junkanki Gakkai zasshi = Pediatric cardiology and cardiac surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44780447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CPVT often causes faint-ness and/or cardiac arrest in younger adults resulting in a poor prognosis, with 60 % ten-year survival. Although 50 ‒ 60 % of CPVT is caused by the mutation in the cardiac ryanodine receptor gene ( RYR2 ), most are sporadic and familial cases are rare. Here we report familial CPVT cases of a 34-year-old woman (proband) and her two sisters. All of them had been implanted with a cardioverter defibrillator (ICD) due to syncope or resuscitated after ventricular fibrillation (VF). Additionally, five of her family members died in their thirties. The genetic study identified a novel pathogenic variant, F4087L, in the RYR2 gene in the proband, her sisters, and proband ʼ s son and niece. Even after ICD implantation, defibrillator shocks were needed to cope with VF in the proband and her sisters. However, additional pharmacological therapies such as beta-blockers, flecainide, and Ca channel blockers could suppress the recurrence of syncope or VF in all patients. These findings suggest that early clinical and genetic diagnosis for CPVT may provide appropriate pharmacological and non-pharmacological therapies to patients and their asymptomatic family members, including infants, for primary prevention of sudden death.","PeriodicalId":89701,"journal":{"name":"Nihon Shoni Junkanki Gakkai zasshi = Pediatric cardiology and cardiac surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46581021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An atrial septal defect (ASD) rarely needs surgical intervention in infancy. However, we report a case of HCM-complicated ASD that required fenestrated ASD closure in early infancy. A 5-month-old girl with cardiofaciocutaneous syndrome was transferred to our institution because of severe lung congestion triggered by fever and convulsions. Echocardiography revealed right ventricle enlargement secondary to left ventricular diastolic dysfunction and severe pulmonary hypertension. She was intubated and supported with mechanical ventilation, with nitric oxide inhalation. Immediately, her ventricular interdependence and circulatory dynamics improved. On hospitalization day 18, cardiac catheterization showed pulmonary hypertension improvement with high pulmonary blood flow and low cardiac out-put. However, she had severe lung congestion triggered by a repeat convulsion on day 60. Thus, we performed ASD partial closure with 4 mm fenestration. Postoperative cardiac catheterization showed a good control of pulmonary blood flow, with a Qp/Qs of 1.3. In conclusion, fenestrated ASD closure is a safe and effective treatment option for left ventricular diastolic dysfunction in early infants with ASD and HCM.","PeriodicalId":89701,"journal":{"name":"Nihon Shoni Junkanki Gakkai zasshi = Pediatric cardiology and cardiac surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47410243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, endogenous cardiomyocytes have limited regenerative capacity. Since our first report of direct cardiac reprogramming from cardiac fibroblasts with three cardiac developmental transcriptional factors (Gata4, Mef2c, and Tbx5), numerous international studies have been reported to reveal the molecular mechanisms of cardiac reprogramming and improve the efficiency of this nascent technology for cardiac regenerative medicine. These advancements include additional transcriptional factors, microRNAs, epigenetic factors, secreted factors, and cellular microenvironment. Cardiac reprogramming of human fibroblasts has also improved. Although direct cardiac reprogramming may resolve the difficulties in applying induced pluripotent stem cells for cardiac regeneration, numerous challenges remain for future clinical application. In this review, we will provide an update on recent advances in research on direct cardiac reprogramming and discuss the perspectives and challenges of this technology in clinical applications.","PeriodicalId":89701,"journal":{"name":"Nihon Shoni Junkanki Gakkai zasshi = Pediatric cardiology and cardiac surgery","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41955552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
