Background: This study was designed to prospectively evaluate the changes in tissue Doppler imaging (TDI) at mitral and tricuspid annuli and two dimensional speckle tracking echocardiography in patients undergoing pericardiectomy for chronic constrictive pericarditis and identify the relationship if any of the tissue Doppler imaging and speckle echocardiographic derived variables with patient’s symptomatic status following surgery. Patients and Methods: Twelve patients undergoing pericardiectomy for constrictive pericarditis aged 7 years to 70 years (median 21; IQR: 19.75-26.5 years) were studied for 2-36 months (median 19 months). They underwent Doppler flow velocity, TDI, and 2D-speckle echocardiographic studies. Friedman’ test was used to test the changes in TDI-derived mitral and tricuspid annular velocities and speckle derived parameters in postoperative period from baseline. Results: Despite congestive heart failure, all patients had normal left ventricular ejection fraction and increased medial mitral and tricuspid early diastolic septal velocity (e¢) with “annulus reversus”. This pattern of annular velocity improved maximally in the immediate postoperative period. At closing interval, 2 (16.7%) patients continued to be in New York Heart Association class II and both of them continued to remain in atrial fibrillation. There was statistical significant improvement in the Global cirumferential strain than in global longitudinal and global radial strain after pericardiectomy. Conclusions: We conclude that tissue Doppler imaging and speckle tracking echocardiography are useful investigative modalities for serial evaluation of patients undergoing pericardiectomy. It can be performed serially with a high degree of reproducibility.

Objective: Recent studies have showed that Tissue Doppler Imaging and Speckle Tracking Echocardiography can discover these changes at functional and structural cardiac in athletes at early stage, especially at the footballers. The purpose of this research was evaluated the structural and functional adaption of left ventricular in footballer by conventional and advanced echocardiography. Materials and methods: We performed a cross-sectional study of 30 footballers who have been trained over 2 years compared to 30 healthy candidate with the same ages. We carried out TM, 2D, STE. Echo machine was Philips Affinity 50CV with QLAB version 10.04 which can analyze online or offline. Result: In comparison with control group, IVSd, LVEDd, PWTd, LVM, LVMI (p = 0.001) was different from athlete group. Left ventricular adaption trended to eccentric hypertrophy and increased left ventricular mass index. A wave was decrease velocity and increased E/A, E/El’, E/E’s ratio. Base circumferential strain, apex circumferential strain, rotation and twist (10.12 ± 1.2) (°) athletes (7.42 ± 2.6) (°) control group with (p = 0.05), were more than control group. Conclusion: Conventional and advanced echocardiography can evaluate structural and functional left ventricular adaption in athletes. Especially, STE provided more data in myocardial deformation, rotation and twist so that it can discover these changes at athlete heart in early stages Key words: Athletes heart, Speckle Tracking Echocardiography, Tissue Doppler Imaging

The aims of this study were i) to evaluate mitral and aortic annuli excursion, and aortomitral angle (AMA) during the cardiac cycle in healthy adults using two-dimensional speckle tracking echocardiography, ii) to assess two annuli dynamics and coupling behaviors as an integral, and iii) to detect the relation between two annuli and left ventricular ejection fraction (LVEF). A total of 74 healthy adults underwent transthoracic echocardiography. In the parasternal long-axis view, a number of points were extracted, including right coronary aortic annular, aortomitral fibrous junction, and posterior mitral annular points. The annuli excursion and AMA were measured using a speckle tracking-derived software during the cardiac cycle. During the isovolumic contraction and the isovolumic relaxation phase, annuli excursion and AMA remain stable for a short time. During the systole, annuli excursion increased sharply to the maximum, while AMA narrowed quickly to the minimum value. During the diastole, there are three patterns of decrease in annuli excursion and AMA expansion in different phases. The annuli excursion of three points correlates well with the LVEF (right coronary aortic annulus excursion, r=0.71, P<0.05; non-coronary aortic annulus excursion, r=0.70, P<0.05; posterior mitral annulus excursion, r=0.82, P<0.05). Moreover, there are positive correlations between annuli excursion and the variation of AMA (r=0.60, P<0.05). The annuli excursion and AMA have various regular patterns in healthy adults. The interactions of mitral and aortic annuli correlate with the left ventricular function. Our findings may have relevance to the evaluation of left ventricular function and presurgical planning of patients with valvular diseases.
