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

Paravalvular regurgitation (PVR) after transcatheter aortic valve replacement (TAVR) is one of the major complications with negative clinical prognosis. Therefore, its prediction is important for further improvement of the outcome. We present a case with TAVR, in which we successfully evaluated aortic valve calcification protruding inward and into the left ventricular outflow tract by real time three‐dimensional transesophageal echocardiography, and predicted significant PVR after the procedure. In conclusion, device landing zone calcification protruding inward is a key for the prediction of significant PVR after TAVR. 相似文献

Ascending aortic pseudoaneurysms (AO PSAs), if left untreated, are complicated by a high rate of rupture resulting in significant morbidity and mortality. New transcatheter modalities have emerged as acceptable surgical alternatives for their management. We present a case of an ascending aortic PSA in which intraoperative two‐ and three‐dimensional transesophageal echocardiography (2DTEE and 3DTEE) provided a comprehensive assessment of the PSA in pre‐ and postclosure settings. 相似文献

In this retrospective study, we identified 7 cases where Lambl's excrescences were identified by two‐dimensional transesophageal echocardiography (2DTEE) and also had live/real time three‐dimensional transesophageal echocardiography (3DTEE) studies available for comparison. We subsequently assessed them for the presence of Lambl's excrescences (LE) and nodules of Arantius (NA) on the aortic valve. After their identification, we qualitatively and quantitatively organized our findings by number, cusp location, measurements, and orientation if applicable. A greater number of LE was found by 3DTEE than 2DTEE (19 vs. 11, respectively). In all 3DTEE studies, their cusp attachment site, their x‐, y‐, and z‐axis measurements, and orientation were clearly visualized and described. Only 3DTEE studies provided confident visualization of the cusp attachment sites. Similarly, a greater number of NA was found by 3DTEE than 2DTEE (21 vs. 5, respectively). The triad of NA was visualized in all 3DTEE studies and each was described using its x‐, y‐, and z‐ axis measurements. Only three 2DTEE studies provided reliable identification of the NA. In conclusion, we present further evidence of the incremental value of 3DTEE over 2DTEE in the qualitative and quantitative assessment of cardiac structures including LE and NA on the aortic valve. 相似文献

A unicuspid aortic valve (UAV) is a rare congenital defect that may manifest clinically as severe aortic stenosis or regurgitation in the third to fifth decade of life. This report describes two cases of UAV stenosis in adult patients diagnosed by transesophageal echocardiography (TEE). The utility of three-dimensional TEE in confirming valve morphology and its relevance to transcatheter valve replacement are discussed. 相似文献

Transcatheter aortic valve implantation (TAVI) is rapidly becoming an accepted treatment option for a selected group of high risk or inoperable patients with severe aortic stenosis. However, this procedure is not without complications. We report a case of acute type A aortic dissection due to balloon aortic valvuloplasty during TAVI that was successfully sealed by the CoreValve prosthesis, thus avoiding surgical intervention.© 2011 Wiley‐Liss, Inc. 相似文献

Coexistence of bicuspid aortic and pulmonary valves in the same patient is a very rare entity identified mainly during surgery and postmortem. To the best of our knowledge, only one case has been diagnosed by two‐dimensional echocardiography in a newborn with malposition of the great arteries but no images were presented. Here, we are reporting the first case of bicuspid pulmonary and aortic valves diagnosed by live/real time three‐dimensional transesophageal echocardiography in an adult with normally related great arteries. 相似文献

Valvular heart diseases cause serious health problems in Turkey as well as in Western countries. According to a study conducted in Turkey, aortic stenosis (AS) is second after mitral valve disease among all valvular heart diseases. AS is frequently observed in elderly patients who have several cardiovascular risk factors and comorbidities. In symptomatic severe AS, surgical aortic valve replacement (AVR) is a definitive treatment. However, in elderly patients with left ventricular dysfunction and comorbidities, the risk of operative morbidity and mortality increases and outweighs the gain obtained from AVR surgery. As a result, almost one‐third of the patients with serious AS are considered ineligible for surgery. Transcatheter aortic valve implantation (TAVI) is an effective treatment in patients with symptomatic severe AS who have high risk for conventional surgery. Since being performed for the first time in 2002, with a procedure success rate reported as 95% and a mortality rate of 5%, TAVI has become a promising method. Assessment of vascular anatomy, aortic annular diameter, and left ventricular function may be useful for the appropriate selection of patients and may reduce the risk of complications. Cardiac imaging methods including 2D and 3D echocardiography and multidetector computed tomography are critical during the evaluation of suitable patients for TAVI as well as during and after the procedure. In this review, we describe the role of echocardiography methods in clinical practice for TAVI procedure in its entirety, i.e. from patient selection to guidance during the procedure, and subsequent monitoring. 相似文献

We present two cases of cor triatriatum, a rare congenital anomaly that consists of a membrane that divides the left atrium into two chambers. The first case involves an older adult man admitted for evaluation of left-sided weakness attributed to stroke. The second is a case of a middle-aged woman with dyspnea. Both patients had transthoracic echocardiograms as a part of their initial evaluation, which revealed abnormal structures in the left atrium, and both subsequently underwent transesophageal echocardiography. During these exams, real-time 3D imaging was utilized to more completely define the pathology. 相似文献
