2D And 3D

Comparison of 3D and 2D speckle tracking performed on standard 2D and triplane 2D datasets of normal and pathological left ventricular (LV) wall-motion patterns with a focus on the effect that 3D volume rate (3DVR), image quality and tracking artifacts have on the agreement between 2D and 3D speckle tracking. 37 patients with normal LV function and 18 patients with ischaemic wall-motion abnormalities underwent 2D and 3D echocardiography, followed by offline speckle tracking measurements. The values of 3D global, regional and segmental strain were compared with the standard 2D and triplane 2D strain values. Correlation analysis with the LV ejection fraction (LVEF) was also performed. The 3D and 2D global strain values correlated good in both normally and abnormally contracting hearts, though systematic differences between the two methods were observed. Of the 3D strain parameters, the area strain showed the best correlation with the LVEF. The numerical agreement of 3D and 2D analyses varied significantly with the volume rate and image quality of the 3D datasets. The highest correlation between 2D and 3D peak systolic strain values was found between 3D area and standard 2D longitudinal strain. Regional wall-motion abnormalities were similarly detected by 2D and 3D speckle tracking. 2DST of triplane datasets showed similar results to those of conventional 2D datasets. 2D and 3D speckle tracking similarly detect normal and pathological wall-motion patterns. Limited image quality has a significant impact on the agreement between 3D and 2D numerical strain values.

Wall Motion Abnormalities

Takotsubo cardiomyopathy is usually described following acute emotional stress. We report here the case of a 48-year-old woman admitted for acute coronary syndrome after an intensive squash match. Diagnosis of Takotsubo cardiomyopathy due to acute physical stress was suspected in presence of normal coronary arteries and transitory left ventricular dysfunction with typical apical ballooning. Cardiac magnetic resonance imaging confirmed regional wall-motion abnormalities and was helpful in excluding myocardial infarction diagnosis. During squash the body is subject to sudden and vigorous demands inducing a prolonged and severe workload on the myocardium.

Echocardiographic Assessment

Background:2D Echo can evaluate LV anatomy, function and diagnose post AMI complications in early stages, thus help in management and determining the prognosis. The present study was undertaken to evaluate LV function in patient following AMI and also to find out the incidence of various echocardiographically detectable complications of following AMI.Methods: The present study was conducted on patients visiting our tertiary health centre during study duration. 50 patients were included in the study. Patients with prior history of acute myocardial infarction, pericarditis and early repolarisation syndrome, and primary myocardial disease diagnosed by serum enzyme levels were not included in the study. Patients were classified as per Killip classification and 2D echo study was performed in all patients.Results: Maximum incidence of AMI was found in 51-60 years of age, with male predominance (64%). Anterior wall AMI (58%) was more common. 94% of patients had wall motion abnormalities. Incidence of LV thrombus was found to be 24%. In present study, as the extent and severity of wall motion abnormalities increased, the incidence of LV thrombus also increased. Thus, 2DE study of LV regional wall motion can predict the incidence of LV thrombus.Conclusions: The echocardiographic assessment of LV function in patients of AMI is important as, it detects the regional wall motion abnormality, LVEF and also the complications like LV thrombus, pericardial effusion and LV aneurysm. These observations are of great value in the management of AMI.
