“…27 Evolving echocardiography techniques-especially involving STE-derived strain and strain rate-appear more suitable to detect subtle myocardial damage and to characterize improvement in myocardial deformation after TAVI. 28 As previously published, 29 we also found in our patients that reduced longitudinal function was more pronounced in basal and medial segments. Acutely after TAVI, only the longitudinal strain of basal and medial segments improved 30 .…”

BackgroundTranscatheter aortic valve implantation (TAVI) has been shown to improve prognosis of high-risk patients. Data, however, concerning the impact of TAVI on regional and global left atrial (LA) and left ventricular (LV) mechanics in varying entities of severe aortic stenosis (AS) are sparse, particularly in patients with paradoxical low-flow (PLF) AS or with reduced LV ejection fraction (LVEF). This study evaluated the effects of TAVI on LA and LV mechanics in varying entities of AS 12 months after implantation. Methods and resultsA total of 54 consecutive patients with severe AS (24 with a normal LVEF and normal flow, 16 with PLF, and 14 with a reduced LVEF) were included. Speckle tracking echocardiography was performed before and 12 months after TAVI to determine LV global and regional longitudinal deformation as well as LA function (reservoir function, conduit phase, and active contraction). In all the three entities of AS, there was a significant improvement in global and regional LV longitudinal function (average global longitudinal strain: 214.1 + 3.9% at baseline vs. 216.5 + 4.0% after TAVI, P , 0.001). Interestingly, the beneficial effects were most pronounced in patients with PLF (214.0 + 2.9 vs. 217.0 + 4.4%, P , 0.031). Moreover, the atrial reservoir and conduit function recovered significantly after TAVI in all patients. ConclusionIn conclusion, regardless of the underlying AS entity, TAVI improves global and regional LV and LA mechanics within 12 months.--

“…While, in the past, segmental deformation could only be assessed in the experimental setting using invasive techniques like sonomicrometry, these image-based deformation assessment tools offer the possibility to quantify deformation in more physiological conditions as well as to investigate patients in a clinical setting. In the past decade, this approach has contributed to a much better understanding of cardiac pathophysiology and the changes in deformation induced by a broad range of cardiac abnormalities [5,6,7,8,9,10,11,12,13,14]. …”

The assessment of cardiac pump function and the potential of local myocardium to contribute to the overall performance are of great importance in many cardiovascular abnormalities. Assessing intrinsic cardiac function requires obtaining information on the true contractility of the heart muscle, assessed locally but interpreted in the context of its contribution to the global ejection performance and potential to adapt to changing circumstances. Contemporary imaging techniques offer the possibility of noninvasive quantification of myocardial deformation. These new clinical tools are attractive to use for the assessment of ventricular function. However, it is of great importance to understand cardiac mechanics – a complex interplay between the tissue structure/shape, force development, and interaction with the environment/neighbors – to interpret alterations in deformation and to extract clinically relevant conclusions. The combination of insight into the measurement techniques and their limitations, together with knowledge of myocardial mechanics and physiology, opens new perspectives to improve the assessment and management of fetal, pediatric, and adult patients.

“…Recently, echocardiographic modalities such as tissue Doppler imaging (TDI) have demonstrated clinical relevance among patients with AS even in the presence of a normal ejection fraction 6 7. Regional myocardial deformation—that is, strain and strain rate, is abnormal in AS.…”
