Summary: This study aimed to investigate the serial changes in left ventricular (LV) myocardial deformation in patients with sepsis. The results showed that LV myocardial strain gradually improved during the ten-day period, but was not fully recovered to normality by the seventh to the tenth days.

Summary: This study aimed to compare strain parameters derived from 2D and 3D speckle tracking echocardiography to explore markers reflecting myocardial fibrosis in patients with dilated cardiomyopathy and advanced heart failure. The results suggest that 3DGLS may be the optimal surrogate marker for reflecting myocardial fibrosis in these patients.

Summary: In recent years, hypertrophic cardiomyopathy (HCM) in cats has become more common due to improvements in diagnostic techniques. This study compared myocardial function in HCM-affected cats with and without left ventricular outflow tract obstruction (DLVOTO) using speckle-tracking echocardiography. The results showed that LV myocardial function was more compromised in HCM-affected cats with DLVOTO, indicating the importance of DLVOTO in affecting LV function in HCM-affected cats.

Summary: Two-dimensional speckle-tracking echocardiography is an advanced imaging technique that allows comprehensive evaluation of myocardial function through deformation imaging. It has gained importance in human medicine over the past decade, with applications for assessing myocardial function, detecting subclinical dysfunction, and as a prognostic indicator. In veterinary medicine, it is particularly useful for early detection of left ventricular dysfunction in dogs.

Summary: The aim of this study was to compare the strain values of infants with severe and critical pulmonary stenosis (PS) with controls, both globally and regionally, and to assess the correlations between strain and conventional parameters. The results showed a significant difference in regional strain values between PS patients and controls. There were also significant changes in strain values from basal to apical location. However, there was no significant difference in strain values before and after intervention in PS patients. The study emphasizes the importance of using strain analysis, specifically RV global-4-chamber longitudinal strain, for evaluating RV function in infants with severe and critical PS.

Summary: Our study suggests that myocardial deformation analysis may not be helpful in concluding on the underlying HCM genotype, and vice versa.

Summary: Fetuses with Tetralogy of Fallot (TOF) exhibit decreased biventricular myocardial deformations, particularly lower LV and RV GLS values, which are correlated with the severity of right ventricular outflow tract obstruction. This suggests that 2D-STE may be a more sensitive tool for assessing fetal cardiac function.

Summary: This study aimed to investigate the predictive value of multiple strain parameters for myocardial fibrosis in patients with hypertrophic cardiomyopathy (HCM) using speckle tracking automated functional imaging (AFI). The results showed that GLS could predict significant myocardial fibrosis.

Summary: The study compared LALS values between 2DE and 3DE in healthy subjects, finding that 3DE gave significantly lower LALS values than 2DE, suggesting that 3DE may overcome the limitation of overestimating LALS in 2DE. The foreshortening of the LA cavity longitudinally in apical views with 2DE may lead to an overestimation of LALS, while 3DE could potentially provide more accurate measurements.

Summary: Hypertrophic cardiomyopathy is a genetic heart disease, and left ventricular apical aneurysm is a rare subtype. Echocardiography-guided percutaneous intra-myocardial septal radiofrequency ablation can be an effective treatment for obstructive hypertrophic cardiomyopathy with left ventricular apical aneurysm.

Summary: The endomyocardial form of restrictive cardiomyopathy (EMF-RCM), a primary disorder of the myocardium, is one of the diseases with poor prognosis in cats. Our study indicated that cats with EMF-RCM have reduced left ventricular myocardial function and certain right ventricular myocardial deformations compared to healthy cats. Myocardial function assessed by two-dimensional speckle-tracking echocardiography could reveal left and right myocardial dysfunction in cats with EMF-RCM.

Summary: The study investigated the relationship between cardiac function and pulmonary flow characteristics in tricuspid valve malformation (TVM) fetuses using conventional and speckle tracking echocardiography. Results showed that TVM fetuses demonstrated biventricular dysfunction in the second and third trimester, with those with reduced or absent pulmonary flow exhibiting significantly greater impairment and more rapid deterioration of cardiac function, potentially leading to poor outcomes.

Summary: The study aimed to elucidate the mechanisms of left ventricle functional recovery after surgical ventricular reconstruction. Real-time 3-dimensional transthoracic echocardiography was performed on patients with anterior left ventricle remodeling and ischemic heart failure. The results showed that surgical ventricular reconstruction led to significant improvement in left ventricle function, indicating the important role of remote myocardium in enhancing recovery.
