“…25 These measurements are not part of the recommended standard intraoperative TEE exam; they were not consistently included in our retrospective studies and were therefore unavailable. 26 Since the principles of measuring wall velocity by STI are related to those for TDI, in our view, this further supported our choice. 27 The relationship of mitral annulus velocities measured by TDI and STI have been compared and are related but not equivalent.…”

Purpose Speckle tracking imaging (STI) is a recent technique that evaluates an echocardiographic image throughout the cardiac cycle and provides dynamic variables such as tissue velocities and strain rates. The objective of our study was to determine 1) if STI can be used to quantify proximal aortic compliance and 2) if decreased aortic compliance determined by STI will reproduce the previously reported correlation with diastolic function. Methods This was a retrospective observational case series using previously obtained intraoperative transesophageal images. Diastolic performance was quantified by STI-based longitudinal velocities of the basal-septal and basal-lateral walls of the left ventricle in early diastole (LV E 0 ). Change in proximal aortic volume was calculated using STI to measure peak longitudinal and radial velocities in early diastole. After normalizing for mean arterial pressure, compliance was calculated and then compared with basal-septal and basal-lateral LV E 0 using single regression analysis.Results Twenty patients were included in our analysis. Linear regression of basal-septal LV E 0 and basal-lateral LV E 0 vs proximal aortic compliance during diastole each resulted in an R 2 value of 0.26 (P \ 0.05). Conclusion Speckle tracking can be used to describe the physical motion of the aortic wall and to calculate its compliance. We confirm that variation in diastolic function can be attributed, in part, to aortic compliance. Our novel approach of measuring compliance throughout the cardiac cycle, isolating radial and longitudinal contributions, and evaluating previously obtained images retrospectively provides advantages over previously reported measures of aortic compliance. Speckle tracking promises new insights into ventricular function, aortic mechanics, and the interaction between these structures. RésuméObjectif L'imagerie de suivi de pixel, ou speckle tracking imaging (STI) en anglais, est une technique re´cente qui permet d'e´valuer une image e´chocardiographique tout au long du cycle cardiaque et d'obtenir des variables dynamiques telles que les ve´locite´s tissulaires et les vitesses de de´formation. L'objectif de notre e´tude e´tait de de´terminer si 1) la STI pouvait eˆtre utilise´e pour quantifier la compliance de l'aorte proximale, et si 2) une compliance aortique re´duite telle que de´termine´e par la STI reproduisait la corre´lation avec la fonction diastolique rapporte´e pre´ce´demment. Méthode Cette e´tude est une se´rie de cas observationnelle re´trospective se fondant sur des images transoesophagiennes perope´ratoires obtenues par le passe´. La performance diastolique a e´te´quantifie´e par les ve´locite´s longitudinales fonde´es sur la STI des parois basales septales et basales late´rales du ventricule gauche en de´but de diastole (LV E 0 ). Les changements de volume de l'aorte proximale ont e´teć alcule´s à l'aide de la STI afin de mesurer les ve´locite´s

“…16,17 The anesthesiologist with a basic level of training will also have the ability to use intraoperative TEE independently as a monitoring and diagnostic tool at a basic level as outlined in this document (Appendix 1). 7,8,12 Therefore, at a basic level of training the anesthesiologist can monitor and diagnose hemodynamic problems related to preload, ventricular systolic or diastolic dysfunction, myocardial ischemia and valvular dysfunction.…”

“…7 However, when the plexus is situated deeper, as in the infraclavicular region or in obese patients, lower frequencies (5-8 MHz) are more appropriate for tissue penetration but have associated less spatial resolution. Broad-beam probes exhibit a range of frequencies (8)(9)(10)(11)(12)(13) and attempt to address this problem by automatically adjusting parameters, such as focal zone and frequency, when adjustments in depth are made. Footprint size and shape also influences the ease of sonographic examination where, for example, large linear probes may be difficult to position behind the clavicle.…”

Purpose The purpose of this narrative review is to describe an anatomical approach for residents-in-training and anesthesiologists who are learning techniques of ultrasound-guided regional anesthesia of the neck and upper limb Sources Relevant articles relating anatomy and anatomical variation to the emerging practice of ultrasoundguided regional anesthesia for the neck and upper limb were sourced via both Medline and PubMed databases. Also, our approach to teaching ultrasound technique has developed from using anatomical resources and cadaveric workshops. This approach emphasizes precise image acquisition, a detailed knowledge of anatomy and anatomical variations, and, importantly, visual interpretation of sonographic landmarks based on pattern recognition when interpreting sonograms. Principal findings Typical sonographic patterns orient the examiner to nerve position, which is necessary for executing successful regional anesthesia of the neck and upper limb. Only by understanding the typical anatomical arrangement can the examiner then visually interpret any individual anatomical variation that may occur. Conclusion Simple sonographic anatomical patterns can provide a strategy to correctly locate nerves when performing ultrasound-guided cervical and brachial plexus anesthesia. RésuméObjectif L'objectif de ce compte-rendu narratif est de de´crire une approche anatomique destine´e aux re´sidents en formation et aux anesthe´siologistes qui apprennent les techniques d'anesthe´sie re´gionale du cou et des membres supe´rieurs par e´choguidage. Sources Les articles pertinents traitant de l'anatomie et des variations anatomiques dans la pratique e´mergente de l'anesthe´sie re´gionale du cou et des membres supe´rieurs par e´choguidage ont e´te´tire´s des bases de donne´es Medline et PubMed. De plus, notre approche de l'enseignement des techniques e´choguide´es a e´volue´graˆce au recours ad es ressources anatomiques et des ateliers sur des cadavres. Cette approche met l'accent sur l'obtention d'images pre´cises, une connaissance de´taille´e de l'anatomie et des variations anatomiques et, composante importante, l'interpre´tation visuelle de points de repe`res e´chographiques selon une reconnaissance des configurations lors de l'interpre´tation des e´chogrammes. Constatations principales Les configurations e´chog-raphiques typiques fournissent des informations al 'examinateur quant a`la position des nerfs, ce qui est ne´cessaire a`la re´alisation d'une anesthe´sie re´gionale du cou et des membres supe´rieurs re´ussie. Il faut que l'examinateur comprenne la disposition anatomique typique pour ensuite pouvoir interpre´ter de façon visuelle les variations anatomiques individuelles potentielles.
