Background: Balloon atrial septostomy (BAS) is an essential catheterization procedure for congenital heart lesions. Recently, a balloon catheter for static BAS was approved for the first time in Japan as an alternative to the conventional pull-through BAS. Despite the expected increase in the use of static BAS, reports on its safety are scarce worldwide.Methods and Results: Data on static and pull-through BAS registered in a national registry between 2016 and 2018 were collected. During the study period, 247 sessions of static BAS and 588 sessions of pull-through BAS were performed on a total of 674 patients. Patients who underwent static BAS were older (P<0.001). The incidence of serious adverse events (4.3% vs. 0.9%, P=0.03) and the overall incidence of adverse events (8.1% vs. 3.2%, P=0.03) were higher in static BAS than in pull-through BAS. Among patients who underwent static BAS, the risk factor for adverse events was a body weight <3 kg at the time of the procedure (odds ratio: 4.3 [confidence interval: 1.7–11], P=0.003).Conclusions: This nationwide study revealed differences in patient background between static and pull-through BAS, as well as a higher incidence of adverse events related to static BAS. Patients weighing <3 kg are at high risk for adverse events after static BAS and may require surgical and circulatory support backup.

A total of 138 animals from 7 species (Apodemus agrarius, Bandicota indica, Crocidura suaveolens, Mus caroli, Mus formosanus, Rattus losea, and Suncus murinus) captured in Taichung, located in central Taiwan, and Kinmen Island, an island off the shore of China, were examined for the presence of Anaplasma phagocytophilum. The presence of the bacteria, which causes human granulocytic anaplasmosis, was examined by nested PCR targeting the16S rDNA. Twelve animals (8.7%) from M. caroli and R. losea, and 25 (18.1%) from A. agrarius, B. indica, M. caroli, and R. losea were infected with A. phagocytophilum and Anaplasma bovis, respectively. Phylogenetic analysis revealed that partial 16S rDNA sequences in the 12 aforementioned animals showed higher similarity to the sequences related to A. phagocytophilum detected in wild rodents (Rattus and Niviventer) from southeast China. The sequences of the other 25 animals belonged to the A. bovis clade. We demonstrated that small wild mammals were infected with A. phagocytophilum and A. bovis in Taichung and Kinmen Island, Taiwan.

A molecular epidemiological survey was conducted to identify the tick-borne disease agents Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato in Selenge Province, Mongolia. The survey was in response to a suspected A. phagocytophilum infection in a patient. In 2012, a total of 129 questing Ixodes persulcatus adult ticks were sampled by flagging vegetation. A. phagocytophilum and Borrelia spp. were detected by PCR, targeting the 16S rDNA (rrs) and 5S–23S intergenic spacer region, respectively. Infection rates for A. phagocytophilum and B. burgdorferi sensu lato spp. were 6.2% and 55.0%, respectively. Six of the 129 ticks (4.9%) were coinfected with A. phagocytophilum and B. burgdorferi sensu lato. Among Borrelia spp., the highest prevalence rate was that for B. garinii 20047 type (26.3%), followed by B. afzelii (7.8%) and B. garinii NT29 type (7.0%). Furthermore, ticks were detected that were dually infected with B. afzelii and B. garinii 20047 type (7.8%) and B. garinii NT29 and 20047 types (6.2%).
