Many coronary stenosis, which are anatomically clear, are not functionally significant. The treatment of such kind of stenosis can cause irreversible effects on the patient. Thus, choosing the best treatment planning depend on anatomical and functional information is very beneficial. An algorithm for the fusion of coronary computed tomography angiography (CCTA) as an anatomical and transthoracic echocardiography (TTE) as a functional modality is presented. CCTA and TTE are temporally registered using manifold learning. A pattern search optimization algorithm, using normalized mutual information, is used to find the best match slice to TTE frame from CCTA volume. By employing a free-form deformation, the heart's non-rigid deformations are modeled. The spatiotemporal registered TTE frame is embedded to achieve the fusion result. The accuracy is evaluated on CCTA and TTE data obt...

Since the heart has nonlinear and dynamic behavior, Temporal Registration (TR) is the fundamental step for the spatial registration and fusion of MCIs to integrate the heart's anatomical and functional information into a single and more informative display. Therefore, in this study, a TR framework is proposed to align MCIs in the same cardiac phase. Materials and Methods: A manifold learning-based method is proposed for the TR of MCIs. The Euclidean distance among consecutive samples lying on the Locally Linear Embedding (LLE) of MCIs is computed. By considering cardiac volume pattern concepts from distance plots of LLEs, six cardiac phases (end-diastole, rapid-ejection, end-systole, rapid-filling, reduced-filling, and atrial-contraction) are temporally registered. Results: The validation of the proposed method proceeds by collecting the...

Unfortunately, the treatment strategies of regional myocardial diastolic dysfunction in patients with CAD have not been well characterized and benefit of percutaneous coronary intervention (PCI) as a treatment strategy is not clear. So the present study aimed to assess the effects of PCI on regional and global left ventricular diastolic dysfunction in patients with CAD assessed by strain rate (SR) imaging. Methods: Thirty adult symptomatic patients with coronary artery disease that underwent coronary angiography and candidate for PCI on left anterior descending artery were enrolled to our study. Echocardiographic findings and early diastolic SR were measured before and 48 hours after PCI. Results: Mean age of the patients was 59.9 ± 8.3 years. Most of the left ventricular diastolic parameters showed significant difference before and after elective PCI; while mitral E velocity, DT, E/A and pulmonary vein flow before and after PCI did not show significant difference assessed by statically test. Also before PCI, mean (SD) of peak early diastolic SR in ischemic regions (1.89 ± 0.22) was smaller than of non-ischemic regions (2.53 ± 0.26) while after PCI this parameter became similar in ischemic regions (2.55 ± 0.27) and non-ischemic regions (2.55 ± 0.26). Conclusion: Most of the left ventricular diastolic parameters improved after PCI in CAD patients. Also regional myocardial relaxation as measured by peak early diastolic SR (ESR) in the ischemic segments improved significantly compared with that in non-ischemic segments.

This study aimed to identify the global longitudinal strain (GLS) changes in isolated overweight and obese people in absence of other risk factors. Method A total of 60 obese people, 30 overweight, and 30 healthy controls were included in the study. Echocardiographic ndings including apical 2-, 3-and 4-chamber GLS, GLS total, left ventricular (LV) diameter, interventricular septum thickness, and PAP were measured and compared between the three groups. Results Analyses showed that LV diameter in healthy controls was signi cantly lower compared to overweight (P = 0.02) and obese (P < 0.0001) participants. Also, the interventricular septal thickness was signi cantly increased in overweight (P = 0.007) and obese (P < 0.0001) individuals compared to participants with normal BMI. The mean and standard deviation (Mean ± SD) of total GLS values were − 22.29% ± 1.89% for normal weight,-22.09% ± 1.91% for overweight, and − 19.88% ± 2.34% for obese individuals. The total GLS of obese participants was signi cantly lower than overweight and normal controls (P < 0.0001). It was observed that the GLS values were signi cantly lower in people with BMI higher than 40. The mean ± SD of total GLS values were − 20.68% (1.84%) for BMI ≤ 40 patients, and − 18.51% (2.52%) for BMI > 40 patients. Conclusion All GLS values had a moderately strong correlation with BMI values. Subclinical LV dysfunction was detected in overweight people in addition to obese subjects.

Using EAT thickness as a cost-efficient assessment tool for stratifying the risk of coronary artery disease (CAD) is still controversial. Methods: We enrolled 250 consecutive patients who underwent coronary angiography during 2016 and gathered their demographic. Echocardiographic examinations were performed in the left lateral decubitus position and EAT thickness was measured in standard parasternal long-axis (PLAX) and apical four chamber views. Results: 250 patients including 156 men (mean age: 57.66) and 94 women (mean age: 61.19) were enrolled. Two vessel disease (2VD) and three vessel disease (3VD) were significantly associated with hyperlipidemia (P: 0.04), CKD (Chronic Kidney Disease) (P: 0.001), diabetes mellitus (P: 0.001) and smoking habits (P: 0.001). Also, EAT thickness in PLAX view (P<0.001), and not four chamber view (P: 0.136), was significantly associated and correlated with increased involvement of coronary arteries in catheterization. Conclusion: Although EAT thickness in PLAX view was significantly correlated with 2VD and 3VD, this correlation was not strong and the accuracy of this approach needs further evaluation.

The goal of this study was to evaluate LV recovery after STEMI intervention based on GLS values. Methods: The study population consists of 43 patients with acute STEMI and no history of prior coronary intervention treated with primary percutaneous coronary intervention. LVEF and myocardial strain indices were measured 48 hours and two months after STEMI by transthoracic echocardiography and speckle tracking method. More than 5% improvement in LVEF was considered significant. Results: GLS values were significantly higher in patients with >5% improvement in LVEF 2 months after the STEMI (GLS=15.76% in patients with >5% improvement vs. 11.54% in the other group, P<0.05). ROC analysis suggested GLS values more than 13.5 to be a predictor of significant LVEF improvement 2 months after STEMI. Higher GLS was observed in patients with inferior, posterior and inferoseptal STEMI versus anterior, extensive or anteroseptal STEMI and in patients with right coronary occlusion versus occlusion of the left anterior descending or circumflex arteries. Conclusion: We have observed that early longitudinal LV strain after STEMI is a predictor of recovery after STEMI. This is a useful method to predict early LV recovery after STEMI. GLS values of more than 13.5% are a significant predictor of significant LVEF improvement.

Results: 250 patients including 156 men (mean age: 57.66) and 94 women (mean age: 61.19) were enrolled. Two vessel disease (2VD) and three vessel disease (3VD) were significantly associated with hyperlipidemia (P: 0.04), CKD (Chronic Kidney Disease) (P: 0.001), diabetes mellitus (P: 0.001) and smoking habits (P: 0.001). Also, EAT thickness in PLAX view (P<0.001), and not four chamber view (P: 0.136), was significantly associated and correlated with increased involvement of coronary arteries in catheterization. Conclusion: Although EAT thickness in PLAX view was significantly correlated with 2VD and 3VD, this correlation was not strong and the accuracy of this approach needs further evaluation.

The goal of this study was to evaluate LV recovery after STEMI intervention based on GLS values. Methods: The study population consists of 43 patients with acute STEMI and no history of prior coronary intervention treated with primary percutaneous coronary intervention. LVEF and myocardial strain indices were measured 48 hours and two months after STEMI by transthoracic echocardiography and speckle tracking method. More than 5% improvement in LVEF was considered significant. Results: GLS values were significantly higher in patients with >5% improvement in LVEF 2 months after the STEMI (GLS=15.76% in patients with >5% improvement vs. 11.54% in the other group, P<0.05). ROC analysis suggested GLS values more than 13.5 to be a predictor of significant LVEF improvement 2 months after STEMI. Higher GLS was observed in patients with inferior, posterior and inferoseptal STEMI versus anterior, extensive or anteroseptal STEMI and in patients with right coronary occlusion versus occlusion of the left anterior descending or circumflex arteries. Conclusion: We have observed that early longitudinal LV strain after STEMI is a predictor of recovery after STEMI. This is a useful method to predict early LV recovery after STEMI. GLS values of more than 13.5% are a significant predictor of significant LVEF improvement.
