Septic pulmonary embolism secondary to prosthetic conduit fungal endocarditis in a child.

An 11 year-old boy underwent pulmonary vegetectomy and right ventricle-to-pulmonary artery conduit replacement for septic pulmonary embolism secondary to prosthetic conduit fungal endocarditis. He had previous surgical history of Senning/Rastelli procedure for corrected transposition of the great arteries at 5 years old. He was diagnosed with prosthetic fungal endocarditis caused by Candida parapsilosis, and suffered from growing vegetation and progressive septic pulmonary embolism despite fungal treatment.

Ventricular assist device for end-stage adult congenital heart disease patients: Current status.

As long-term surgical outcome of congenital heart disease has continued to improve, most pediatric patients with congenital heart disease are able to reach adulthood. However, adult congenital heart disease (ACHD) patients have increased risk of arrhythmia, valvular diseases, infectious endocarditis, and heart failure. The end-stage ACHD patients with advanced heart failure may require mechanical circulatory support to improve the heart failure symptoms or to recover from circulatory collapse, and may eventually aim to heart transplant or destination therapy.

Current status and challenges of Pediatric heart transplantation in Japan.

It has been about 10 years since the revised Japanese Organ Transplant Law came into action. Organ donation from brain dead donors has increased in the past decade, but the number of recipients waiting for transplant is increasing more rapidly. Implantable continuous flow ventricular assist device, such as Jarvik 2000 and HeartWare, available from 2011, and Berlin heart EXCOR, available from 2015, has changed the scene for children with severe heart failure.

Outcomes of Restrictive Cardiomyopathy in Japanese Children - A Retrospective Cohort Study.

Background: There has been no nationwide survey on the prognosis of pediatric restrictive cardiomyopathy (RCM) in Japan; therefore, this retrospective multicentered study was designed to investigate the long-term survival rate of pediatric patients with RCM in Japan.

Methods and results: A multicentered, retrospective observational study was performed between 1990 and 2014 and included patients diagnosed with RCM who were aged <18 years from 18 Japanese institutions. A total of 54 patients were diagnosed with RCM.

Management of pregnancy and delivery in women with transposition of the great arteries after atrial switch operation: A 16-year single-center experience.

Aim: This study aimed to summarize cases of successful pregnancy and delivery in patients with transposition of the great arteries (TGA) after atrial switch operation (ASO), to provide management, clinical experience, and maternal and fetal outcomes.

Methods: During a 16-year period (2004-2019), we experienced 30 pregnancies in 15 patients after ASO at our institution. We retrospectively reviewed the medical records of the patients.

Outcomes of Dilated Cardiomyopathy in Japanese Children - A Retrospective Cohort Study.

Background: There has been no nationwide survey on the prognosis of pediatric dilated cardiomyopathy (DCM) in Japan. Therefore, we designed this retrospective multicenter study to investigate the long-term survival rate in pediatric patients with DCM in Japan.

Methods and results: In this multicenter retrospective observational study, data were reviewed for 106 patients aged <18 years who had been diagnosed with DCM at any 1 of 18 Japanese institutions between 1990 and 2014.

Complete remission from post-heart transplant lymphoproliferative disorder: A case report.

We report a case of Burkitt's lymphoma, post-transplant lymphoproliferative disorder (BL-PTLD) that was treated with intensive chemotherapy. The patient was a 4-year-old boy who underwent heart transplantation at 7 months of age for refractory heart failure due to dilated cardiomyopathy. He was admitted to our hospital with a chief complaint of abdominal pain associated with an abdominal mass.

Predictors of neo-aortic valve regurgitation in the long term after arterial switch operation.

Although arterial switch operations (ASOs) have been performed globally to repair d-transposition of the great arteries (d-TGA) in neonates and infants, few studies have been reported regarding the influence of the hemodynamics of patients with d-TGA who have undergone ASO on the development of neo-aortic valve regurgitation (AR). We aimed to investigate the relationship between the hemodynamics and development of AR after ASO in patients with d-TGA by catheter evaluation. This observational study screened 114 consecutive patients who underwent ASO for d-TGA or Taussig-Bing anomaly and who subsequently underwent catheter evaluations in our institution.
