“…The validation results have a close agreement with results of previous studies, which assessed peak systolic strain in normal subject using TMRI [33][34][35][36]. The concept of assessment of myocardial viability based on the analysis of function has been proven in many previous studies to allow reliable evaluation of the extent of myocardial infarction in ischemic cardiomyopathy [2,[37][38][39][40][41]. As a threshold of 50% hyper-enhancement was reported in previous studies to regain functional recovery [5,15,42,43], this cutoff value was chosen to differentiate between non-transmural and transmural infarcted tissue.…”

AimsTo evaluate a novel post-processing method for assessment of longitudinal mid-myocardial strain in standard cine cardiac magnetic resonance (CMR) imaging sequences. Methods and resultsCine CMR and tagged cardiac magnetic resonance imaging (TMRI) were performed in 15 patients with acute myocardial infarction (AMI) and 15 healthy volunteers served as control group. A second group of 37 post-AMI patients underwent both cine CMR and late gadolinium enhancement (LGE) CMR exams. Speckle tracking echocardiography (STE) was performed in 36 of these patients. Cine CMR, TMRI and STE were analyzed to obtain longitudinal strain. LGE-CMR datasets were analyzed to evaluate scar extent. Comparison of peak systolic strain (PSS) measured from CMR and TMRI yielded a strong correlation (r=0.86, p<0.001). PSS measured from CMR and STE correlated well (r=0.75, p<0.001). A cutoff longitudinal PSS value of -13.14% differentiated non-infarction from any infarcted myocardium, with a sensitivity of 93% and a specificity of 89% (area under curve (AUC) 0.95). PSS value of -9.39% differentiated non-transmural from transmural infarcted myocardium, with a sensitivity of 75% and a specificity of 67% (AUC 0.78). ConclusionThe present study showed a novel off-line post-processing method for segmental longitudinal strain analysis in mid-myocardium layer based on cine CMR data. The method was found to be highly correlated with strain measurements obtained by TMRI and STE. This tool allows accurate discrimination between different transmurality states of myocardial infarction.

“…This study complements prior work using velocity vector imaging (one element of which is speckle tracking) to identify regional wall motion abnormalities in patients with ischemic heart disease 10 and argues successfully that strain-rate imaging based on speckle tracking has the potential to facilitate regional wall motion analysis. However, only time and additional studies will determine whether automating scoring will succeed where prior quantitative approaches have failed in moving to the clinical mainstream.…”

“…7 Moreover, it is possible to evaluate regional ventricular dysfunction more accurately. In a recent study by Kepez et al, apical RV peak systolic strain and SR values were significantly lower in OSA patients, while no significant differences regarding other segmental strain and SR values were observed even in the absence of pulmonary hypertension.…”

bstructive sleep apnea (OSA) is common, underdiagnosed and associated with cardiovascular diseases such as heart failure, left ventricular (LV) and right ventricular (RV) dysfunction, myocardial infarction, arrhythmias, and systemic and pulmonary hypertension. 1 Previous studies have shown the adverse affects of OSA on both LV and RV functions. 2,3 However, many risk factors for OSA, such as excess weight, male sex and advanced age, are the same as the risk factors for cardiovascular diseases. Proving that OSA actually causes cardiac dysfunction independent of these confounding risk factors is difficult. Early recognition of RV dysfunction before pulmonary arterial (PA) hypertension develops is important for preventing further progression to heart failure and even death. 4 Thus, there is a need for a more detailed analysis of its pathophysiologic importance and for techniques that may supplement available technology in identifying early signs of RV impairment. Editorial p 250Recently, tissue Doppler imaging (TDI) and strain/strain rate (SR) imaging have been shown to be reliable and accurate novel techniques for evaluating global and regional ventricular function. 5 As TDI has the disadvantage of being preload and afterload dependent, a new TDI-derived index of isovolumic myocardial acceleration (IVA) has been validated to be a reliable and relatively load independent measure of cardiac systolic function. 6 Velocity vector imaging (VVI) is a novel method based on 2-dimensional B-mode images. The method involves tracking ultrasonic speckles permitting angle-independent measurement of tissue velocity and deformation. 7 It has been shown to be a reliable method for the quantification of regional contractile dysfunction with the ability to detect subclinical cardiac dysfunction. 8 In this study, VVI and TDI were used to evaluate regional subclinical RV dysfunction in newly diagnosed moderate-to-severe OSA The aims of this study were to evaluate subclinical regional right ventricular (RV) dysfunction in newly diagnosed obstructive sleep apnea (OSA) patients without systemic and pulmonary arterial (PA) hypertension, and to correlate OSA severity to RV dysfunction, using both velocity vector imaging (VVI)-derived strain imaging and tissue Doppler imaging (TDI).
