14. Untreated atrial septal defect after intracardiac repair for tetralogy of Fallot.

Author

Tanaka, Keisuke, Katayama, Yuzo, Isobe, Sho, Ozawa, Tsukasa, and Fujii, Takeshiro

Abstract

Tetralogy of Fallot was repaired previously in a preschooler through right ventriculotomy, providing excellent exposure for ventricular septal defect closure and right ventricular outflow tract obstruction relief. Herein, we describe the preschooler as a 50-year-old man with untreated atrial septal defect found at pulmonary valve replacement in the remote period after tetralogy of Fallot repair. It was inferred intraoperatively that the previous tetralogy of Fallot was repaired only through right ventriculotomy, and atrial septal defect closure was performed together with pulmonary valve replacement.

18. Radical Esophagectomy Combined with Resection of the Invaded Descending Aorta for T4 Barrett's Esophageal Carcinoma: A Case Report

Subjects
Barrett's esophageal adenocarcinoma, T4 aorta
Abstract

Case Report, A 58-year-old Japanese man was diagnosed with T4b (descending aorta) N2M1, stage IVB lower thoracic Barrett's esophageal adenocarcinoma. He was initially treated with definitive chemotherapy with cisplatin and 5-fluorouracil (FP therapy). After one course of FP therapy, he developed renal dysfunction complications. Computed tomography showed no remarkable change in the main tumor and metastatic lesion. Therefore, radical esophagectomy with resection of the invaded descending aorta and removal of the solitary metastatic lesion was performed. Superior mediastinal dissection, esophageal transection, and left adrenal gland removal were performed simultaneously. The patient underwent curative resection but died of multiple hematogenous metastases 116 days postoperatively. As aortic infiltrates were infected, artificial blood vessel replacement was selected. Although he underwent radical esophagectomy, hematogenous metastases have occurred in the early postoperative period.

20. Novel Treatment for Atrial Septal Defect without an Inferior Septal Rim and Partial Anomalous Right Lower Pulmonary Venous Connection

Subjects
partial anomalous right lower pulmonary venous connection, atrial septal defect without an inferior septal rim, autologous tissue
Abstract

Case Report, There is no consensus regarding the ideal surgical procedure for treatment of combined atrial septal defect without an inferior septal rim and partial anomalous right lower pulmonary venous connection. A 41 year-old woman had previously undergone ineffective surgical closure of an ostium secundum-type atrial septal defect. Intraoperatively, we ascertained the correct diagnosis of partial anomalous right lower pulmonary venous connection combined with a residual defect. Incision of the atrial septal wall up to the superior margin along the previous suture line yielded a flap adequate for the atrial septal wall, and this flap was slid again into the entire opening. The spatially complex intracardiac lesion was repaired by using only autologous tissue.

21. Antibacterial Effects of Vascular Grafts Treated with Rifampicin, Colistin, Vancomycin, or Daptomycin

Abstract

Original Article, Introduction: Some reports suggest that rifampicin treatment of vascular grafts is useful when surgically treating vascular infections and mycotic aneurysms. However, the experimental evidence is limited, and the antibacterial effects of other antibiotic-treated vascular grafts are unknown. Methods: Vascular grafts were immersed in several antibiotic solutions (rifampicin, colistin, vancomycin, or daptomycin). After Pseudomonas aeruginosa PAO1 or Staphylococcus aureus N315 were inoculated into the graft exterior, the number of colony-forming units (CFU) inside and outside the grafts was measured over time. Moreover, bonding of colistin and vancomycin to the grafts was quantified. Results: For grafts immersed in rifampicin, the CFU values outside the grafts decreased over time and those inside the grafts did not increase when the grafts were exposed to a 106 CFU/mL concentration of PAO1 or N315. However, at 108 CFU/mL, the CFU values increased over time outside and inside the grafts. In PAO1 testing, grafts treated with colistin resisted pathogens in the tested area, and grafts treated with both colistin and rifampicin had even greater resistance. In N315 testing, vancomycin-treated grafts had some resistance to infection, but daptomycin-treated grafts did not. The bonding of colistin and vancomycin to the grafts depended on the immersion time. Conclusions: Rifampicin-bonded grafts have a strong antibacterial effect when the concentrations of pathogens are low. Colistin-bonded grafts are effective against P. aeruginosa infection, and vancomycin-bonded grafts are effective against S. aureus infection.

Abstract

We evaluated the impact of donor age on the efficacy of myocardial cellular therapy for ischemic cardiomyopathy. Characteristics of smooth muscle cells (SMC), bone marrow stromal cells (MSCs), and skeletal muscle cells (SKMCs) from young, adult, and old rats were compared in vitro. Three weeks after coronary ligation, 3.5 million SMCs (n = 11) or MSCs (n = 9) from old syngenic rats or culture medium (n = 6) were injected into the ischemic region. Five weeks after implantation, cardiac function was assessed by echocardiography and the Langendorff apparatus. In the in vitro study, the numbers and proliferation of MSCs from fresh bone marrow and SKMCs from fresh tissue but not SMCs were markedly diminished in old animals (P < 0.05 both groups). SKMCs from old animals did not reach confluence. After treatment with 5-azacytidine (azacitidine), the myogenic potential of old MSCs was decreased compared with young MSCs. In the in vivo study, both SMC and MSC transplantation induced significant angiogenesis compared with media injections (P < 0.05 both groups). Transplantation of SMCs but not MSCs prevented scar thinning (P = 0.03) and improved ejection fraction and fractional shortening (P < 0.05). Load-independent indices of cardiac function in a Langendorff preparation confirmed improved function in the aged SMC group (P = 0.01) but not in the MSC group compared with the control group. In conclusion, donor age adversely impacts the efficacy of cellular therapy for myocardial regeneration and is cell-type dependent. SMCs from old donors retain their ability to improve cardiac function after implantation into ischemic myocardium. myocardial infarction; aging
