ABSTRACT Aiming to provide cardiovascular morphophysiology information on the Cuniculus paca, an important neotropical rodent, eight healthy adult females of this species were evaluated three times by echocardiography under general anesthesia with isoflurane every 15 days. The exams were performed by a single experienced evaluator with the animals positioned in right and left decubitus. Posteriorly, two expert evaluators measured the cardiac chambers, walls and flow patterns, by B-mode, M-mode, and Doppler ultrasonography. The resulting values were compared among evaluators and periods by the Bland-Altman agreement test and several descriptive statistics were presented for each parameter. Echocardiographic images were obtained between the second and fifth left and right intercostal spaces, enabling the measurement of heart chambers and walls, mitral, tricuspid, aortic and pulmonary valves blood flows, and the ejection and shortening fractions calculation. None of the studied variables showed inter-observers or inter-periods variations. This study provided some normal echocardiographic variables, applicable to epidemiological, pathophysiological or case studies in the Cuniculus paca and phylogenetically close species.

This is a comprehensive practical guide to the practice of the new subspecialty of critical care echocardiography. The text covers all aspects of clinical practice and describes how to use transthoracic echocardiography to approach and manage common clinical questions. Specific emphasis is placed on the appropriate use of clinical echocardiographic data in the context of the patient’s critical illness; this is illustrated by the frequent use of case studies including both still and moving echocardiographic images. The text covers assessment of, and disorders affecting, the left and right heart, including shock and sepsis. It also looks at how to interpret diastolic information during critical illness and the effect of that illness on valve disease and function. The important subject of fluid responsiveness is explored in detail, as is the influence of organ support and illness on the diagnosis of cardiac tamponade. The information given in the text is summarized using algorithms in a field guide for the critical care echocardiographer, which also provides a rapid guide to assessing time-critical patient presentations.

Abstract Ventricle dysfunction is the most common cause of heart failure, which leads to high mortality and morbidity. The mechanical behavior of the ventricle is critical to its physiological function. It is known that the ventricle is anisotropic and viscoelastic. However, the understanding of ventricular viscoelasticity is much less than that of its elasticity. Moreover, the left and right ventricles (LV&RV) are different in embryologic origin, anatomy, and function, but whether they distinguish in viscoelastic properties is unclear. We hypothesized that passive viscoelasticity is different between healthy LVs and RVs. Ex vivo cyclic biaxial tensile mechanical tests (1, 0.1, 0.01Hz) and stress relaxation (strain of 3, 6, 9, 12 15%) were performed for ventricles from healthy adult sheep. Outflow track direction was defined as the longitudinal direction. Hysteresis stress-strain loops and stress relaxation curves were obtained to quantify the viscoelastic properties. We found that the RV had more pronounced frequency-dependent viscoelastic changes than the LV. Under the physiological frequency (1Hz), the LV was more anisotropic in the elasticity and stiffer than the RV in both directions, whereas the RV was more anisotropic in the viscosity and more viscous than the LV in the longitudinal direction. The LV was quasi-linear viscoelastic in the longitudinal but not circumferential direction, and the RV was non-linear viscoelastic in both directions. This study is the first to investigate passive viscoelastic differences in healthy LVs and RVs, and the findings will deepen the understanding of biomechanical mechanisms of ventricular function.
