Infective endocarditis is a heterogeneous disease with a wide array of pathological lesions. We present a 55-year-old man with severe mitral and aortic regurgitation on transthoracic echocardiography. Transesophageal echocardiogram characterized the mechanisms detecting a windsock mitral valve perforation, aortic root abscess, and Gerbode ventricular septal defect, with the deep transgastric view showing all three pathologies concurrently. The etiologies of mitral valve perforation and Gerbode defects are discussed. Transesophageal echocardiography remains a critical imaging modality to diagnose and evaluate the extent of infective endocarditis with superior sensitivity to transthoracic echocardiography. 相似文献

Introduction
We conducted the present study to determine whether a combination of the mechanical ventilation weaning predictors proposed by the collective Task Force of the American College of Chest Physicians (TF) and weaning endurance indices enhance prediction of weaning success. 相似文献7.

It is unclear why some species become successful invaders whilst others fail, and whether invasive success depends on pre-adaptations already present in the native range or on characters evolving de-novo after introduction. Ants are among the worst invasive pests, with Lasius neglectus and its rapid spread through Europe and Asia as the most recent example of a pest ant that may become a global problem. Here, we present the first integrated study on behavior, morphology, population genetics, chemical recognition and parasite load of L. neglectus and its non-invasive sister species L. turcicus. We find that L. neglectus expresses the same supercolonial syndrome as other invasive ants, a social system that is characterized by mating without dispersal and large networks of cooperating nests rather than smaller mutually hostile colonies. We conclude that the invasive success of L. neglectus relies on a combination of parasite-release following introduction and pre-adaptations in mating system, body-size, queen number and recognition efficiency that evolved long before introduction. Our results challenge the notion that supercolonial organization is an inevitable consequence of low genetic variation for chemical recognition cues in small invasive founder populations. We infer that low variation and limited volatility in cuticular hydrocarbon profiles already existed in the native range in combination with low dispersal and a highly viscous population structure. Human transport to relatively disturbed urban areas thus became the decisive factor to induce parasite release, a well established general promoter of invasiveness in non-social animals and plants, but understudied in invasive social insects. 相似文献
