Hypertrophic cardiomyopathy (HCM) is the most common genetically transmitted cardiomyopathy. In patients resistant to medical management, myectomy is the surgical procedure of choice to reduce the symptoms of left ventricular outflow obstruction. Two‐dimensional transesophageal echocardiography (2DTEE) has become part of the operative procedure by decreasing the incidence of postoperative complications. However, because of the three‐dimensional geometry of left ventricular outflow tract, it is unable to comprehensively assess the location and severity of the obstruction and to provide accurate guidance during myectomy. In this study, 10 patients with HCM underwent live/real time three‐dimensional transesophageal echocardiography (3DTEE) intra‐operatively to measure the volume of the resected septum. This volume correlated well with the volume of the resected septal muscle directly obtained using a graduating cylinder containing water (r = 0.9, P < 0.000). 3DTEE may be potentially used as an adjunct to guide the surgeon in performing an adequate myectomy with a lower incidence of residual obstruction and complications such as an iatrogenic ventricular septal defect. 相似文献

Purpose: To evaluate left ventricular (LV) regional systolic function and dyssynchrony in patients with dilated cardiomyopathy (DCM) by real time three‐dimensional echocardiography (RT‐3DE). Methods: The study population comprised 30 normal controls (NOR) and 44 patients with DCM. We divided the left ventricle into apical, middle, and basal regions. We calculated the LV regional end‐diastolic volume (REDV), regional end‐systolic volume (RESV), regional ejection fraction (REF), and standard deviation in the time to minimal systolic volume in each level segment (Tmsv‐SD) of the three regions by RT‐3DE. Results: Compared with NOR, the REDV, RESV, and Tmsv‐SD of DCM were significantly higher, whereas the REF was lower (P < 0.01). In DCM, the Tmsv‐SD increased smoothly from base to apex, and the REF gradually decreased from base to apex (P < 0. 05). Linear correlation was observed between the Tmsv‐SD of the middle region and 3D‐EF in DCM (r =?0. 6829, P < 0.01). Conclusion: RT‐3DE provides a simple and feasible approach to quantify LV regional systolic function and dyssynchrony. (ECHOCARDIOGRAPHY 2010;27:415‐420) 相似文献

We describe a 77‐year‐old female with hypertrophic cardiomyopathy in whom live/real time three‐dimensional transesophageal echocardiography (3DTEE) provided incremental value over two‐dimensional transthoracic and transesophageal echocardiography (2DTTE, 2DTEE) and three‐dimensional transthoracic echocardiography (3DTTE) in making a more comprehensive assessment and a more confident diagnosis of caseous mitral annular calcification. 3DTEE revealed a portion of the mass to consist of small, multiple, highly echogenic discrete band‐like and punctate areas within a relatively much less echogenic stroma and surrounded by a well defined highly echogenic border. This appearance correlated with the pathological findings of calcific granules/strands located in a liquefied or semiliquefied interior providing a typical toothpaste like appearance. The highly echogenic outer border represented the residual outer portion or rim of the calcific mass which did not undergo liquefaction. These findings on 3DTEE which correlated with the toothpaste like appearance seen at surgery were not visualized on 2DTTE, 2DTEE, and 3DTTE. (Echocardiography 2010;27:1147‐1150) 相似文献

Endomyocardial fibrosis is a form of restrictive cardiomyopathy mainly affecting poor children and young adults in geographically restricted areas of Latin America, Africa, and Southeast Asia. The pathophysiological hallmark of the disease is focal or diffuse endocardial thickening involving mainly the inflow, the apices, and the subvalvular region leading to valvular regurgitation, diastolic dysfunction and obliteration of the ventricular apex. Advanced right‐sided disease has slow flow of blood through chambers with propensity of thrombus formation especially in the right atria. Although two‐dimensional transthoracic echocardiography remains the cornerstone for the diagnosis of this disease, the case presented here shows how three‐dimensional transthoracic echocardiography can add substantial information regarding the region of involvement of the right ventricle as well as the various characteristics of the right atrial thrombus. 相似文献

Patients with hypertrophic obstructive cardiomyopathy undergoing alcohol septal ablation are presented. Three‐dimensional speckle tracking echocardiography (3DSTE) is a new, noninvasive tool for quantification of myocardial deformation. In both cases, 3DSTE was performed 1 day before and 3 days after alcohol septal ablation to quantify changes in septal strain of ablated area. Results could suggest the possible role of 3DSTE in the quantitative evaluation of the success of alcohol septal ablation. 相似文献

We present an adult patient in whom live/real time three‐dimensional transesophageal echocardiography (3DTEE) provided incremental value in the assessment of the spinal cord as compared to two‐dimensional transesophageal echocardiographic (2DTEE) findings published in the literature. It improved accurate identification and assessment of the anterior radiculomedullary spinal arteries which may have an important clinical application in monitoring for spinal cord ischemia during thoracic aortic surgery. Because the spinal cord and spinal canal could be examined using not only transverse but also coronal (frontal), sagittal, and oblique planes, 3DTEE further allowed for three‐dimensional measurements of the dimensions and volumetric analysis of the visualized spinal cord and spinal canal. These may have implications in the assessment of spinal cord edema due to trauma and other conditions which result in increase in the size and volume of the spinal cord. 相似文献

Purpose: Although nonobstructive prosthetic valve thrombosis (PVT) does not develop hemodynamic compromise, it carries potential risk for thromboembolism. Real time three‐dimensional transesophageal echocardiography (RT‐3DTEE), has emerged as a complementary tool in depicting “en face” views of prosthesis compared with two‐dimensional transesophageal echocardiography (2DTEE). We aimed to evaluate the utility of RT‐3DTEE in assessment of mitral ring‐located thrombosis. Method: We present 3 cases of mechanical mitral valve thrombosis complicated by thromboembolism, who were all examined and followed‐up by 2D transthoracic echocardiography (TTE), 2DTEE, and RT‐3DTEE. Result: The consequencies of thromboembolism in the patients were coronary embolism, transient ischemic attack, and ischemic stroke, respectively. They were all inadequately anticoagulated at the time of admission. 2DTTE and TEE examination was unsatisfactory; RT‐3DTEE depicted nonobstructive mitral ring thrombosis in each of the patients. The patients were followed up under effective anticoagulation and antiplatelet therapy. RT‐3DTEE was able to demonstrate the evolution of thrombus size in each of the patients. Conclusion: Nonobstructive ring‐located PVT which poses risk for thromboembolism, may be diagnosed with certainty and imaged with clarity utilizing RT‐3DTEE. 相似文献

Double‐Chambered Right Ventricle with Ventricular Septal Defect and Subaortic Membrane— Three‐Dimensional Echocardiographic Evaluation 下载免费PDF全文
Rajiv Bharat Kharwar M.D. D.M. Sudhanshu Kumar Dwivedi M.D. D.M. Akhil Sharma M.D. D.M. 《Echocardiography (Mount Kisco, N.Y.)》2016,33(2):323-327
Double‐chambered right ventricle (DCRV) is a rare congenital anomaly in which the right ventricle is divided into two compartments with varying pressures due to an anomalous muscle bundle. Here, we describe a case of an adolescent male with DCRV with associated ventricular septal defect and subaortic membrane. Two‐dimensional and three‐dimensional transthoracic echocardiography with color flow clearly outlined all the three cardiac anomalies as well as their relationship with each other. The diagnosis was confirmed by cardiac catheterization. The patient underwent successful surgical resection of the anomalous muscle bundle along with repair of the associated anomalies. 相似文献
