Abstract Background: Endocardial fibroelastosis (EFE) is a rare heart disease characterized by the thickening of the endocardium caused by massive proliferation of collagenous and elastic tissue, usually leading to impaired cardiac function. Thrombosis is a complication of EFE that suggests poor prognosis.Case presentation: The present report describes an EFE patient with multiple cardiovascular thrombi. To the best of our knowledge, this is the first reported case of three-dimensional (3D) and contrast echocardiography use in EFE with multiple ventricular thrombi. The clinical features and outcomes of this rare condition between 1966 and 2019 are also reviewed.Conclusions: Through the combination of 3D and contrast echocardiography, the thrombus can be displayed more accurately and vividly, including its nature and density and the connection between the base of the thrombus and ventricular wall. EFE prognosis with left ventricular thrombus is generally poor.

Abstract Background A displaced left B1 + 2 accompanied by an anomalous pulmonary vein is a rare condition involving complex structures. There is a risk of unexpected injuries to bronchi and blood vessels when patients with such anomalies undergo surgery for lung cancer. Case presentation A 59-year-old male with suspected lung cancer in the left lower lobe was scheduled to undergo surgery. Chest computed tomography revealed a displaced B1 + 2 and hyperlobulation between S1 + 2 and S3, while the interlobar fissure between S1 + 2 and S6 was completely fused. Three-dimensional computed tomography (3D-CT) revealed an anomalous V1 + 2 joining the left inferior pulmonary vein and a branch of the V1 + 2 running between S1 + 2 and S6. We performed left lower lobectomy via video-assisted thoracic surgery, while taking care with the abovementioned anatomical structures. The strategy employed in this operation was to preserve V1 + 2 and confirm the locations of B1 + 2 and B6 when dividing the fissure. Conclusion The aim of the surgical procedure performed in this case was to divide the fissure between S1 + 2 and the inferior lobe to reduce the risk of an unexpected bronchial injury. 3D-CT helps surgeons to understand the stereoscopic positional relationships among anatomical structures.

Background: We aimed to explore the value of combining real-time three-dimensional echocardiography (RT-3DE) and myocardial contrast echocardiography (MCE) in the left ventricle (LV) evaluating myocardial dysfunction in type 2 diabetes mellitus (T2DM) patients.Patients and Methods: A total of 58 T2DM patients and 32 healthy individuals were selected for this study. T2DM patients were further divided into T2DM without microvascular complications (n = 29) and T2DM with microvascular complications (n = 29) subgroups. All participants underwent RT-3DE and MCE. The standard deviation (SD) and the maximum time difference (Dif) of the time to the minimum systolic volume (Tmsv) of the left ventricle were measured by RT-3DE. MCE was performed to obtain the perfusion measurement of each segment of the ventricular wall, including acoustic intensity (A), flow velocity (β), and A·β.Results: There were significant differences in all Tmsv indices except for Tmsv6-Dif among the three groups (all P < 0.05). After heart rate correction, all Tmsv indices of the T2DM with microvascular complications group were prolonged compared with the control group (all P < 0.05). The parameters of A, β, and A·β for overall segments showed a gradually decreasing trend in three groups, while the differences between the three groups were statistically significant (all P < 0.01). For segmental evaluation of MCE, the value of A, β, and A·β in all segments showed a decreasing trend and significantly differed among the three groups (all P < 0.05).Conclusions: The RT-3DE and MCE can detect subclinical myocardial dysfunction and impaired myocardial microvascular perfusion. Left ventricular dyssynchrony occurred in T2DM patients with or without microvascular complications and was related to left ventricular dysfunction. Myocardial perfusion was reduced in T2DM patients, presenting as diffuse damage, which was aggravated by microvascular complications in other organs.

Background Accurate detection of left ventricular thrombus (LVT) affects clinical management of at risk pts. CE-MRI identifies LVT based on tissue characteristics and has been validated as a highly sensitive technique that improves LVT detection vs non-contrast echo. However prior comparative studies were performed without echo contrast agents, which can improve echo LVT detection. We studied diagnostic performance of contrast (C-ECHO) and non-contrast echo (NC-ECHO) vs a reference of CE-MRI for LVT detection. Methods We prospectively enrolled pts with ejection fraction (EF) <50% referred for CE-MRI (1.5 T) to evaluate for LVT. NC-ECHO and C-ECHO (Definity; perflutren lipid microspheres) were performed within 7 (mean 1.2 ± 1.6) days of CE-MRI. Studies were interpreted blinded to results of the other modality. LVT were scored for location, volume and type (mural or intracavitary). EF was measured by cine-MRI planimetry. Cine and CE-MRI were scored via a 17 segment model to quantify wall motion and scar. Results 80 pts were studied (age 63 ± 13, 90% CAD, NYHA 2.4 ± 0.7). CE-MRI identified LVT in 25 pts (31%). 84% of LVT were apically located; 32% were mural. All LVT were adjacent to myocardial scar. Pts with LVT by CE-MRI had larger transmural scar size (25 vs 16% of LV segments; p = 0.01) but similar EF (30 vs 33%; p = 0.4) and wall motion score index (2.3 vs 2.1; p = 0.4) to those without LVT. C-ECHO had nearly 2 fold higher diagnostic sensitivity (p = 0.02) and improved accuracy (p = 0.02) vs NC-ECHO (table ). However, C-ECHO did not detect 32% of LVT identified by CE-MRI. LVT missed by C-ECHO were more likely to be mural (p < 0.01). Apically located LVT were more likely to be missed when small (0.9 vs 4.1 cm3; p = 0.01) while detection of non-apical LVT was independent of size. Conclusions While echo contrast improves diagnostic performance for LVT, a substantial number of LVT identified by CE-MRI are not detected by C-ECHO. LVT missed by C-ECHO are typically mural in shape or, if apical, small in volume. Left Ventricular Thrombus Detected by CE-MRI (n = 25)
