Multiplane transesophageal echocardiography: a basic oblique plane patient imaging sequence.
We have previously reported a standardized 10-step sequence of monoplane (transverse plane) transesophageal two-dimensional echocardiographic views and a standardized 7-step vertical plane examination, both suitable for expeditious intraoperative use by the beginning practitioner. A multiplane transesophageal examination involves transverse plane views, vertical plane views and the remaining "in-between" oblique plane views. This report describes a sequence of specific oblique views to be used as a framework for the completion of a multiplane transesophageal examination. Each of these steps is illustrated with a two-dimensional echocardiographic image, a matching diagram and a schematic representation of the corresponding axis of interrogation. This description of oblique plane imaging, therefore, completes the components of a multiplane transesophageal examination.

Transesophageal echocardiographic imaging workshop: a basic transverse plane examination sequence.
This workshop describes a 10-step sequence of transverse plane two-dimensional transesophageal echocardiographic views of the heart and great vessels that constitutes a basic standardized examination capable of being performed by a beginning practitioner.

Patent foramen ovale and paradoxical embolization: a historical perspective.
The use of transesophageal echocardiography for intraoperative management of critically ill patients allows for routine evaluation of foramen ovale patency. The high prevalence of preoperatively unrecognized flow-patency of this structure has led investigators to emphasize the potential for paradoxical embolization in any patient undergoing anesthesia. This perspective led us to research earliest documentation of paradoxical embolization through a patent foramen ovale as a historical issue with present day relevance. This report examines the 1877 text of Julius Cohnheim in which he described a fatal case of paradoxical embolization to the middle meningeal artery. The 1880 manuscript of Moritz Litten documenting paradoxical embolization to the lower extremity is also presented. Both translations, to our knowledge, represent the first such representations of both the original 1877 edition of Cohnheim's work and Litten's journal article.
