Transcatheter valve-in-valve (VIV) implantation has been recently proposed as an alternative to surgical reoperative aortic valve replacement in patients with a failing aortic bioprosthesis. Experience with transcatheter VIV implantation at other valve positions is very limited. Herein is reported the case of an 18-year-old man with Ebstein's anomaly and severe tricuspid valve (TV) regurgitation status after bioprosthetic valve replacement, who developed new dyspnea on exertion three years after the initial valve replacement...

BACKGROUND: Various approaches such as antegrade trans-septal, retrograde transfemoral and transapical techniques have been used to close mitral paravalvular leak (PVL) in patients with an aortic prosthesis. During the implementation of these techniques, an arteriovenous guidewire loop is often created for device delivery. However, passing through a mechanical aortic valve may cause hemodynamic compromise and prolong the procedure. To date, no studies have evaluated antegrade mitral PVL closure without the use of an arteriovenous wire loop in patients with a mechanical aortic prosthesis...

BACKGROUND: Stabilization of the ventriculo-aortic junction (VAJ) is gaining increasing interest in the context of aortic valve repair, since its dilation is a well-recognized risk factor for long-term repair failure. Interleaflets triangles are key elements of the VAJ, but cannot be completely visualized using echocardiography. A three-dimensional (3D) reconstruction of electrocardiogram-triggered computed tomography (CT) scan images allows an analysis of the real dimensions and anatomic characteristics of the subcommissural triangles...

Three-dimensional (3D) printing has attracted a huge interest in recent years. Broadly speaking, it refers to the technology which converts a predesigned virtual model to a touchable object. In clinical medicine, it usually converts a series of two-dimensional medical images acquired through computed tomography, magnetic resonance imaging or 3D echocardiography into a physical model. Medical 3D printing consists of three main steps: image acquisition, virtual reconstruction and 3D manufacturing. It is a promising tool for preoperative evaluation, medical device design, hemodynamic simulation and medical education, it is also likely to reduce operative risk and increase operative success...

Lisa Qia Rong
Transesophageal echocardiography (TEE) was first used routinely in the operating rooms in the 1980s to facilitate surgical decision-making. Since then, TEE has evolved from the standard two-dimensional (2D) exam to include focused real-time three-dimensional (RT-3D) imaging both inside and outside the operating rooms. Improved spatial and temporal resolution due to technological advances has expedited surgical interventions in diseased valves. 3D imaging has also emerged as a crucial adjunct in percutaneous interventions for structural heart disease...

Traumatic tricuspid regurgitation is a rare and progressive disease. Early diagnosis and surgical valve repair are very important. A 57-year-old male was referred to our hospital with a history of blunt chest trauma. Three-dimensional echocardiography showed severe tricuspid regurgitation and demonstrated two main anterior leaflet chordaes of the tricuspid valve rupture and the whole anterior leaflet prolapsed. The diagnosis was severe tricuspid regurgitation due to leaflet chordae rupture secondary to blunt chest trauma...

In this article, we report a rare case of double aortic arch. The case presented initially with a foreign object in the oesophagus. The patient was a 2-year-old boy, who was referred with primary symptoms of tussis (15 days) and emesis (2 days). He had a history of ingesting a coin. Routine chest X-ray indicated a rounded, metal foreign object in the upper oesophagus. A half-Yuan coin was removed by gastroduodenoscopy. Echocardiographic imaging suggested that the patient had double aortic arch, which was subsequently diagnosed by CT angiography with three-dimensional reconstruction...

BACKGROUND: Echocardiography is a valuable noninvasive technique to estimate cardiac output (CO) from the left ventricle (LV) not only in clinical practice but also in small-animal experiments. CO is used to grade cardiac function and is especially important when investigating cardiac injury (e.g., myocardial infarction [MI]). Critically, MI deforms the LV, invalidating the assumptions fundamental to calculating of cardiac volumes directly from the LV. Thus, the purpose of this study was to determine if Doppler-derived blood flow through the pulmonary trunk (pulmonary flow [PF]) was an improved method over conventional LV-dependent echocardiography to accurately determine CO after MI...

BACKGROUND: Functional mitral regurgitation (MR) can occur in patients with atrial fibrillation (AF) despite having preserved left ventricular (LV) systolic function. This MR is known as atrial functional MR. The aim of this study was to clarify the mechanism of atrial functional MR using real-time three-dimensional transesophageal echocardiography (3DTEE). METHODS: Sixty patients underwent transthoracic echocardiography and 3DTEE: 16 patients with AF and significant non-organic MR and preserved LV ejection fraction (>50%) constituted the AF-MR group, 20 patients with AF and no significant MR formed the AF-NSMR group, and 24 normal subjects comprised the control group...

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...

Ostial lesions represent a challenging clinical scenario and percutaneous intervention (PCI) of left main coronary artery ostial lesions has been associated with postintervention complications, including protrusion of deployed stents into a sinus of Valsalva or aortic root. We report a case of stent protrusion into the aortic root following aorto-ostial left main coronary artery PCI, in which three-dimensional transesophageal echocardiography (3DTEE) provided incremental benefit over standard two-dimensional images...

BACKGROUND: The currently proposed criteria for identifying patients who would benefit from cardiac resynchronization therapy (CRT) still need to be optimized. A multi-scale heart simulation capable of reproducing the electrophysiology and mechanics of a beating heart may help resolve this problem. The objective of this retrospective study was to test the capability of patient-specific simulation models to reproduce the response to CRT by applying the latest multi-scale heart simulation technology...

BACKGROUND: In CHD, three-dimensional strain analysis may overcome limitations of Doppler and two-dimensional strain of the left ventricle. The aims of this study were to evaluate feasibility and reproducibility of three-dimensional longitudinal, circumferential, and radial systolic strain by three-dimensional speckle-tracking echocardiography compared with two-dimensional echocardiography. METHODS: Patients with CHD, biventricular circulation with a systemic left ventricle, and who had two- and three-dimensional imaging performed on the same day from 2010 to 2014 were included...

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...

Estimation of right ventricular (RV) performance still remains technically challenging due to its anatomical and functional distinctiveness. The current guidelines for the echocardiographic quantification of RV function recommend using multiple indices to describe the RV in a thorough and comprehensive manner, such as RV index of myocardial performance, tricuspid annular plane systolic excursion, fractional area change, Doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'-wave), three-dimensional RV ejection fraction (3D RVEF), longitudinal strain (RVLS)/strain rate by speckle-tracking echocardiography (STE)...

Speckle tracking echocardiography (STE) has recently emerged as a quantitative technique to accurately estimate myocardial function. By the analysis of the motion of speckles in the two-dimensional ultrasonic image, this technique allows a non-Doppler angle-independent objective analysis of myocardial deformation, with the possibility to quantify thickening, shortening and rotation dynamics of cardiac function. Since this technique does not require Doppler imaging, the analysis is relatively angle-independent and is marginally affected by cardiac in-plane motion artifacts...

: Transesophageal echocardiography is frequently performed for further evaluation of sources of embolism and better evaluation of atrial septum in patients with cerebral ishemic events. Although two-dimensional transesophageal echocardiography can depict atrial septal aneurysm and patent foramen ovale, the full extent of the patent foramen ovale cannot be easily discerned in some cases. We describe a patient with transient cerebral ischemia where three-dimensional echocardiography provided incremental value when compared to two-dimensional transesophageal echocardiography in the assessment of atrial septal aneurysm and patent foramen ovale...
