AIM: To apply real time three-dimensional transesophageal echocardiography (RT3D TEE) for quantitative and qualitative assessment of the mitral valve annulus (MVA) and tricuspid valve annulus (TVA) in the same patient. METHODS: Our retrospective cohort study examined the MVA and TVA in 49 patients by RT3D TEE. MVA and TVA shape were examined by TEE. The MVA and TVA volume data set images were acquired in the mid esophageal 4-chamber view. The MVA and TVA were acquired separately, with optimization of each for the highest frame rate and image quality...

Real time three dimensional transesophageal echocardiography (3D TEE) is probably the most powerful and convincing imaging method for understanding the complicated multiform morphology and for evaluating geometry, dynamics and function of degenerative and functional mitral valve (MV) regurgitation. Moreover, color Doppler 3D TEE has been valuable to identify the location of the regurgitant orifice and the severity of the mitral regurgitation. 3D TEE has been shown to be of enormous value in helping surgeons to perform MV repair...

Mitral regurgitation (MR) is frequent and associated with increased mortality and morbidity when severe. It may be caused by intrinsic valvular disease (primary MR) or ventricular deformation (secondary MR). Imaging has a critical role to document the severity, mechanism, and impact of MR on heart function as selected patients with MR may benefit from surgery whereas other will not. In patients planned for a surgical intervention, imaging is also important to select candidates for mitral valve (MV) repair over replacement and to predict surgical success...

Iatrogenic injury to the aortic valve is a rare but frequently reported complication during mitral valve surgeries. Intraoperative 2-dimensional transesophageal echocardiography (2D TEE) has a major impact in diagnosing these injuries, so that timely intervention is possible. However, 2D TEE has lot of limitations during the perioperative period, which can be overcome by the three dimensional echocardiography (3D-TEE). We report a case where 3D TEE has undoubtedly delineated the cause for distortion of aortic sinus after mitral valve replacement and helped in the successful outcome...

BACKGROUND: Transcatheter mitral valve repair (TMVR) has been shown to have acute effects on mitral valve geometry in patients with functional mitral regurgitation (FMR). This study investigates the impact of MitraClip(®) therapy-induced annular remodeling on clinical outcome and mitral regurgitation in heart failure patients. METHODS: TMVR was performed successfully in 45 patients with FMR. In this study, mitral valve datasets were obtained before and directly after MitraClip(®) implantation using three-dimensional (3D) transesophageal echocardiography, and were analyzed offline retrospectively using dedicated 3D reconstruction software...

A 28-year-old man was admitted to our emergency service with a shortness of breath and palpitation. On admission, his blood pressure was high and he was in hypertensive pulmonary edema. His physical examination showed rales in both lungs and pansystolic murmur at mitral focus. His medical history included aortic valve replacement (AVR) because of native aortic valve infective endocarditis. Transthoracic echocardiography (TTE) showed normal functional aortic valve. Color flow imaging demonstrated severe mitral regurgitation with posterior eccentric jet...

Chronic aortic regurgitation (AR) induces mitral valve (MV) leaflet enlargement, although, its mechanism still remains unclear. This study aimed to clarify the influence of AR jet directions on the MV apparatus in patients with chronic AR. This study included 69 consecutive patients with severe chronic AR and 17 controls who underwent three-dimensional (3D) transesophageal echocardiography (TEE). The anterior mitral leaflet (AML), posterior mitral leaflet (PML) and MV annulus areas were measured at mid-diastole...

BACKGROUND: The extent of mitral annular (MA) remodeling and dysfunction is correlated with the severity of mitral regurgitation (MR) as well as left atrial (LA) and left ventricular (LV) dilation. MA dysfunction may be a useful prognostic factor for operative timing and MR recurrence after successful mitral valve (MV) repair. The aim of this study was to evaluate additive prognostic factors of MA non-planarity using real-time 3D transesophageal echocardiography (RT3D-TEE) analysis in patients with chronic severe MR and preserved LV systolic function...

The tricuspid valve (TV), although occasionally considered "neglected" is the subject of renewed and increasing interest. Factors include an awareness that tricuspid value dysfunction is influential in patient outcomes, an improving understanding of valve anatomy and function and evolving techniques available to address tricuspid regurgitation. Tricuspid regurgitation (TR) can be classified as being due to primary diseases of the valve or functional in nature, with the majority being functional. Whilst it was previously believed that such functional TR, resulting from left sided disease, would resolve after correction of the underlying pathology this is now known not to be true...

Primary cardiac tumors are exceedingly rare. They are usually first identified by transthoracic echocardiography. However, transesophageal echocardiography (TEE), with the aid of real-time three-dimensional (3D) imaging, can provide additional important mass characteristics. We present a case that demonstrates the usefulness of 3D TEE in characterizing a papillary fibroelastoma.

BACKGROUND: A comprehensive evaluation of mitral stenosis (MS) severity commonly utilizes two-dimensional (2D) echocardiography techniques. However, the complex three-dimensional (3D) structure of the mitral valve (MV) poses challenges to accurate measurements of its orifice area by 2D imaging modalities. We aimed to assess MS severity by comparing measurements of the MV orifice area using conventional echocardiography methods to 3D orifice area (3DOA), a novel echocardiographic technique which minimizes geometric assumptions...

OBJECTIVES: This study aimed to assess the hypothesis that mitral annular disjunction (MAD) is associated with abnormal annular dynamics due to decoupling of annular-ventricular function. BACKGROUND: MAD, defined as a separation between the atrial wall-mitral valve (MV) junction and left ventricular (LV) attachment, is a structural abnormality occurring in MV prolapse (MVP). Few data exist on the 3-dimensional (3D) geometry of MAD and its functional implication...

PURPOSE: Management of patients with mitral stenosis (MS) depends heavily on the accurate quantification of mitral valve area (MVA) using echocardiography. All currently used two-dimensional (2D) methods have limitations. Estimation of MVA using the proximal isovelocity surface area (PISA) method with real time three-dimensional (3D) echocardiography may circumvent those limitations. We aimed to evaluate the accuracy of 3D direct measurement of PISA in the estimation of MVA. METHODS: Twenty-seven consecutive patients (median age of 63 years; 77...

Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed...

The objective of this study was to investigate the usefulness of intraprocedural hemodynamic monitoring for MR evaluation during pMRV. Assessment of mitral regurgitation (MR) during percutaneous mitral valve repair (pMVR) procedure is challenging. 3D color Doppler allows exact quantification of MR, but is technically demanding. Sixty patients with moderate to severe MR (14 with structural and 46 functional MR) were included in the study. Intraprocedural pressure curves were continuously obtained in the left atrium (LA) and left ventricle (LV)...
