Non-Doppler Two-dimensional Strain Imaging by Echocardiography–From Technical Considerations to Clinical Applications

Can We Improve Outcomes in Patients With Previous Coronary Artery Bypass Surgery Admitted for Acute Coronary Syndrome?

“…6,7 In these patients, there are 2 potential explanations, not mutually exclusive, for a new major coronary event, namely, progression of atherosclerotic disease in native arteries or the development of vascular disease in the grafts. Previous authors of an angiography study reported 8% venous graft failure at 1 year, 38% at 5 years, and 75% at 10 years after surgery, 8 and progression of the atherosclerotic process in up to 51% 15 years after CABG. 9 The prognosis of this subset of patients, nevertheless, remains doubtful.…”

Prediction of Short-Term Outcomes in Patients With Idiopathic Dilated Cardiomyopathy Referred for Transplantation Using Standard Echocardiography and Strain Imaging

“…Too low frame rate results in excessive displacement of the speckles between the frames, and too high frame rate is associated with high levels of noise. The optimal frame rate for 2D speckle tracking is 50-70 frames per second (FPS) (67,68,71).…”

Assessment of the Left Ventricle Systolic Function With Ultrasound 2d-Strain Technology in Arterial Hypertension

“…С появлением ультразвуковой технологии 2D-стрейн (speckle tracking), основанной на опреде-лении скорости движения миокарда при помощи отслеживания перемещения естественных акустиче-ских маркеров на стандартном эхокардиографиче-ском (ЭхоКГ) изображении в В-режиме, стало воз-можным изучение глобальной и регионарной сокра-тимости миокарда [3]. Благодаря технологии 2D-стрейн стало возможным изучение показателей деформации миокарда, апикальной и базальной рота-ции, скручивания и раскручивания ЛЖ, что позво-ляет по-новому оценивать физиологию сокращения и расслабления миокарда.…”
