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

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.
