Right single coronary artery as an incidental finding in Takotsubo syndrome and acute heart failure: Case report and review of the literature

ConclusionRight SCA with congenital absence of the LCA is one of the rarest coronary artery anomalies. In a significant percentage of patients it is associated with ischemia and can be life-threatening. CCTA and MRI are the modalities of choice for diagnosis and risk stratification.ResumoIntroduçãoArtéria coronária única (ACU) sem cardiopatia congénita associada é uma entidade rara. Maioria dos casos é assintomática e achados acidentais, mas podem causar isquémia, insuficiência cardíaca congestiva e morte súbita (MS).Caso clínicoMulher, 44 anos, com cardiomiopatia Takotsubo e choque cardiogénico. Canulação seletiva da artéria coronária esquerda (ACE) não possível na coronariografia, tendo-se revelado uma ACU a emergir do seio direito, que se continuava distalmente como artéria circunflexa e, posteriormente, como artéria descendente anterior. Angio-tomografia computorizada coronária (ATCC) confirmou atrésia tronco comum, sem estenoses coronárias. A ressonância magnética cardíaca (RMN) mostrou edema miocárdico difuso, sem defeitos perfusão. Evolução favorável sob tratamento conservador.DiscussãoOs autores descrevem um achado acidental de uma ACU direita. Reportam um tipo R-I de Lypton, onde a ACU direita dominante irriga todo o miocá...

ConclusionsFrailty assessment may be good value for money. However, limited availability of geriatric consultation services, may hinder implementation. Thus, the estimated benefits of frailty screening may not be achievable in practice.

ConclusionsThis case series demonstrates that the use of a high frequency jet ventilator for cardiac MRI was feasible, safe, providing good quality cardiac imaging and avoiding anesthesia personnel to be inside the hazardous environment of MRI room. Future studies are needed to confirm its safety and efficiency in pediatric patients.ResumoJustificativa e objetivosA ressonância magnética (RM) cardíaca é uma técnica utilizada na avaliação de crianças com cardiopatias congênitas. A anestesia geral garante imobilidade, especialmente em pacientes não cooperador...

With the performance of thoracic and abdominal enhanced computed tomography (CT) and upper gastrointestinal contrast, once esophageal cancer was suspected. Significant activity mass in esophagus and mediastinal lymph nodes could be found on the imaging of 18F-FDG PET/CT, which also supported malignancy. However, T...

ConclusionsPKD can be a manifestation of PFBC, and brain calcification may be a cause of secondary PKD. So thoroughly evaluation including head CT or genetic screening for paroxysmal dyskinesia and PFBC should be applied before the diagnosis of PKD or PFBC. Moreover, negative brain calcification may not exclude the possibility of PFBC. The possible pathogenesis of primary calcification lie in the dysfunction of the protein or defective signal transduction caused by the mutations.

HallAbstractIn animal models, exposure to high noise levels can cause permanent damage to hair-cell synapses (cochlear synaptopathy) for high-threshold auditory nerve fibers without affecting sensitivity to quiet sounds. This has been confirmed in several mammalian species, but the hypothesis that lifetime noise exposure affects auditory function in humans with normal audiometric thresholds remains unconfirmed and current evidenc...

We report significant links between the rate of neuroplastic change of cortical surface anatomy, and children's early mathematical skills. In particular, most of the behavioral variance (about 73%) of children's visuospatial abilities was explained by the change in cortical thickness in the right superior parietal cortex. Moreover, half of the behavioral variance (about 55%) of children's arithmetic abilities was explained by the change in cortical folding in the right intraparietal sulcus. Additional associations for arithmetic abilities were found for cortical thickness change of the right temporal lobe, and the left mid...

Li, Rongjun YuAbstractLife stress has been shown to impact cognitive functions, including inhibitory control. However, the immediate effects of acute stress on inhibitory control and the underlying neural mechanisms remain unclear. In a behavioral pilot study (N = 30) and a within-subject functional magnetic resonance imaging study (N = 30), we examined how acute stress induced by Trier Social Stress Test influenced inhibitory control in a stop signal task. Behavioral results across two studies showe...

Lesions are currently detected using T1-weighted, T2-weighted, and gadolinium-enhanced magnetic resonance imaging (MRI); however, monitoring such lesions has been shown to be a poor predictor of disease progression.
