“…Moreover, according to our study on the learning curve for RV strain ( 53 ), novice analysts took more time to reach an expert level than LV strain. LV GLS required only 50 studies to achieve American College of Cardiology (ACC)/American Heart Association (AHA)/ASE echocardiography level III competency, whereas RV FWLS required 100 studies for training.…”

Right ventricle (RV) failure is a common complication of many cardiopulmonary diseases. Since it has a significant adverse impact on prognosis, precise determination of RV function is crucial to guide clinical management. However, accurate assessment of RV function remains challenging owing to the difficulties in acquiring its intricate pathophysiology and imaging its complex anatomical structure. In addition, there is historical attention focused exclusively on the left ventricle assessment, which has led to overshadowing and delayed development of RV evaluation. Echocardiography is the first-line and non-invasive bedside clinical tool for assessing RV function. Tricuspid annular plane systolic excursion (TAPSE), RV systolic tissue Doppler velocity of the tricuspid annulus (RV S'), and RV fractional area change (RV FAC) are conventional standard indices routinely used for RV function assessment, but accuracy has been subject to several limitations, such as load-dependency, angle-dependency, and localized regional assessment. Particularly, load dependency is a vexing issue, as the failing RV is always in a complex loading condition, which alters the values of echocardiographic parameters and confuses clinicians. Recently, novel echocardiographic methods for improved RV assessment have been developed. Specifically, “strain”, “RV-pulmonary arterial (PA) coupling”, and “RV myocardial work” are newly applied methods for RV function assessment, a few of which are designed to surmount the load dependency by taking into account the afterload on RV. In this narrative review, we summarize the latest data on these novel RV echocardiographic parameters and highlight their strengths and limitations. Since load independency is one of the primary advantages of these, we particularly emphasize this aspect.

“…Of significance, one study suggested RV LS to be a potentially superior predictor of 30-day mortality in acute pulmonary embolism than conventional echocardiographic parameters such as RV fractional area change (FAC) and tricuspid annular plain systolic excursion (28). At least 100 studies are required to achieve expert competency for independent RV strain reporting (29).…”

OBJECTIVE: This narrative review aims to discuss the potential applicability of speckle-tracking echocardiography (STE) in patients under mechanical ventilation (MV) and mechanical circulatory support (MCS). Both its benefits and limitations were considered through critical analyses of the current available evidence. DATA SOURCES AND STUDY SELECTION: A literature search was conducted in PubMed and Excerpta Medica Database indexed databases (2012–2021). In addition, the reference lists of all selected studies were manually scanned for further identification of potentially relevant studies. DATA EXTRACTION: The terms “Speckle-Tracking Echocardiography,” “Mechanical Ventilation,” “Mechanical Circulatory Support,” “Extracorporeal Membrane Oxygenation,” “Ventricular Assist Devices,” and “Left Ventricular Unloading Devices” were searched for the identification of relevant articles for narrative synthesis. DATA SYNTHESIS: STE is a well-established post-processing method of analyzing myocardial function, with potentially greater clinical utility than conventional 2D echocardiography. STE has been incorporated into the guideline recommendations for both the diagnostic and prognostic evaluations of myocardial and valvular pathologies. However, the potential of STE application within critical care settings has not yet been fully realized. Its utility in the assessment of patients undergoing MV and MCS is substantial. Specifically, it may serve as an ideal modality in the assessment of subtle changes in cardiac function. In the limited number of studies reviewed, STE was consistently a more sensitive marker of myocardial functional change, compared with traditional markers of 2D and Doppler parameters during changes in MV and MCS. CONCLUSIONS: Although current evidence is extremely limited, STE strain is suggested to be a more sensitive and reproducible parameter of myocardial function than conventional echocardiographic parameters and may have value in the assessment of patients undergoing MV and MCS in critical care settings. Further studies in larger populations are required to elucidate STE’s prognostic capability and its value as a point-of-care tool in guiding clinical practice for subjects under MV and MCS.

“…Estudos sobre curva de aprendizado relataram que são necessários no mínimo cem estudos de análise de SPL-VD para que um iniciante possa atingir o nível de competência de um especialista. 26,32 Dentre as perspectivas, deve-se mencionar o strain do VD realizado pelo método tridimensional. Este pode ser uma ferramenta interessante, uma vez que fornece dados tanto da função longitudinal quanto das funções circunferencial e radial dessa cavidade.…”
