Abstract	Moderate-to-severe tricuspid regurgitation affects approximately 1.6 million people in the United States. An estimated 8000 patients will undergo tricuspid surgery annually, leaving a large number of patients with this condition untreated. Many of these individuals who are not referred for surgery engender a large unmet clinical need; this may be primarily due to the surgical risk involved. In persons who are categorized as high-risk surgical candidates, percutaneous procedures present a viable alternative. The majority of developmental attention as regards percutaneous approaches has been focused on the aortic and mitral valves recently, but few data are available about the feasibility and efficacy of minimally invasive tricuspid valve treatment. We review the usefulness of two- and three-dimensional echocardiography in the assessment of the tricuspid valve with special reference to recent interest in percutaneous repair and prosthetic valve implantation procedures for severe functional tricuspid regurgitation.

Abstract	Objectives: To explore our initial experience with real time three-dimensional transesophageal echocardiography (RT3DTEE) for the assessment of prosthetic valves (PV). Methods: The study included 40 patients (mean age 35 ± 8.5 years, 68% male) who underwent PV implant. Fifty PV (34 bioprosthetic and 16 mechanical) were evaluated using two-dimensional (2D)TEE and RT3DTEE to rule out PV dysfunction. Results: In all patients, RT3DTEE allowed good and simultaneous visualization of PV leaflets. Ten patients had normal functioning PV (5 in mitral, 3 in aortic, and 2 in tricuspid positions). Infective endocarditis was evident in 13 patients (20 PV) by repeated 2DTEE. RT3DTEE confirmed the 2DTEE diagnosis of endocarditis in same patients. Clear delineation of vegetations (size, site, and number) was obtained from RT3DTEE full volume while the vegetation attachment, consistency, mobility and its relation to valve structure were obtained using zoom 3D. Paraaortic abscesses size, site, extension, wall thickness of the abscess could be identified by RT3DTEE in 7 PV. Through cropping of the full-volume 3D images, the orifice of communication between the abscess cavity and aorta could be visualized well in en face view. Color full-volume allowed the detection of paravalvular regurgitation (size, location, direction, and extent) in 8 patients. In the 18 PV who underwent redo surgery, the intra-operative findings confirmed the RT3DTEE description of PV lesions. Conclusion: Real time 3DTEE improved the anatomical and functional assessment of PV with better understanding of the underlying causes of PV dysfunction; hence, it could improve the management planning for such patients.

Abstract	Although 2-dimensional (2D) transesophageal echocardiography (TEE) is the gold standard for the diagnosis of prosthetic valve thrombosis, nonobstructive clots located on mitral valve rings can be missed. Real-time 3-dimensional (3D) TEE has incremental value in the visualization of mitral prosthesis. The aim of this study was to investigate the utility of real-time 3D TEE in the diagnosis of mitral prosthetic ring thrombosis. The clinical outcomes of these patients in relation to real-time 3D transesophageal echocardiographic findings were analyzed. Of 1,263 patients who underwent echocardiographic studies, 174 patients (37 men, 137 women) with mitral ring thrombosis detected by real-time 3D TEE constituted the main study population. Patients were followed prospectively on oral anticoagulation for 25 ± 7 months. Eighty-nine patients (51%) had thrombi that were missed on 2D TEE and depicted only on real-time 3D TEE. The remaining cases were partially visualized with 2D TEE but completely visualized with real-time 3D TEE. Thirty-seven patients (21%) had thromboembolism. The mean thickness of the ring thrombosis in patients with thromboembolism was greater than that in patients without thromboembolism (3.8 ± 0.9 vs 2.8 ± 0.7 mm, p <0.001). One hundred fifty-five patients (89%) underwent real-time 3D TEE during follow-up. There were no thrombi in 39 patients (25%); 45 (29%) had regression of thrombi, and there was no change in thrombus size in 68 patients (44%). Thrombus size increased in 3 patients (2%). Thrombosis was confirmed surgically and histopathologically in 12 patients (7%). In conclusion, real-time 3D TEE can detect prosthetic mitral ring thrombosis that could be missed on 2D TEE and cause thromboembolic events.

Abstract	Prosthetic valve thrombosis (PVT) is a rare but serious complication of valve replacement, most often encountered with mechanical prostheses. The different therapeutic modalities for PVT (fibrinolysis with heparin treatment or surgery) will largely be influenced by the presence of valvular obstruction, the valve location (left or right sided), the patient's clinical status, the existence of and expertise in therapeutic modalities at the institution, and the patient's decision. This report describes a patient with thrombosis of a prosthetic mitral valve, which was successfully treated with recombinant streptokinase in a hospital without cardiac surgery. In this context, the authors present the real-time transoesophageal echocardiographic appearance of this complication, and give a brief review of the literature.

Abstract	Objectives: Two-dimensional (2D) echocardiographic approaches are not sufficient to determine the origin of paravalvular leak (PVL) that occurs after prosthetic mitral valve replacement (MVR). In this study, we investigated the role of real-time three-dimensional transesophageal echocardiography (RT-3D TEE) in detecting the origin and size of PVL occurring after prosthetic MVR. Study design: The study included 13 patients (7 females; 6 males; mean age 56+/-10 years; range 37 to 71 years) who developed PVL within a mean of 8.3+/-3.8 years following mechanical prosthetic MVR. Nine patients (69.2%) had atrial fibrillation, and four patients (30.8%) had normal sinus rhythm. Four patients (30.8%) had hemolysis. Paravalvular leak was mild, moderate, and severe in two, six, and five patients, respectively. Real-time 3D TEE was performed using a 3D matrix-array TEE transducer immediately after detection of PVL on 2D TEE examination. Localization of PVL was made using a clock-wise format in relation to the aortic valve and the size of dehiscence was measured. Results: The mean PVL width measured by 2D TEE was 3.00+/-0.92 mm. The mean length of dehiscence was 13.6+/-8.8 mm, and the mean width was 3.88+/-2.04 mm on RT-3D TEE. The PVLs were mainly localized in the posterior and anterior annular positions between 12 to 03 hours (n=7) and 06 to 09 hours (n=3) on RT-3D TEE, respectively, which corresponded to the posteromedial or anterolateral sectors of the posterior annulus. Conclusion: Considering that only the width of the PVL defect can be assessed by 2D TEE, delineation by RT-3D TEE includes the localization of PVL together with the length and width of the defect.
