BACKGROUND: Transthoracic 3D cardiac analysis is enticing in its potential simplicity and wealth of data available. It has been suggested to be accurate vs magnetic resonance imaging in relatively stable patients, but feasibility and agreement with conventional echocardiographic assessment of stroke volume (SV) have not been thoroughly assessed in critically ill patients, who are traditionally harder to image. The objectives of this study were to compare 3D transthoracic volumetric analysis vs Doppler assessment of SV (which is suggested to be accurate in the critically ill) and Simpson's biplane assessment in a cohort typical of the intensive care unit (ICU), where accurate assessment is important: mechanically ventilated patients with a significant ventilation/perfusion (V/Q) mismatch...

BACKGROUND: Mitral valve (MV) prolapse is common in children with Marfan syndrome (MFS) and is associated with varying degrees of mitral regurgitation (MR). However, the three-dimensional (3D) morphology of the MV in children with MFS and its relation to the degree of MR are not known. The goals of this study were to describe the 3D morphology of the MV in children with MFS and to compare it to that in normal children. METHODS: Three-dimensional transthoracic echocardiography was performed in 27 patients (3-21 years of age) meeting the revised Ghent criteria for MFS and 27 normal children matched by age (±1 year)...

BACKGROUND: Aortic valve calcification (AVC) quantification is computed from multidetector computed tomography (MDCT). The aim of this study was to test the hypothesis that three-dimensional (3D) transthoracic echocardiography can be used to provide a bedside method to assess AVC. METHODS: The study included 94 patients (mean age, 78 ± 12 years; mean aortic valve [AV] area, 1.0 ± 0.6 cm2 ) referred for MDCT and echocardiography for AV assessment. Apical 3D full-volume data sets focused on the AV region were acquired during transthoracic echocardiography, and a region-growing algorithm was applied offline to compute 3D transthoracic echocardiographic AVC (AVC-3DEcho)...

Cardio-oncology is a new field of interest in cardiology that focuses on the detection, monitoring, and treatment of cardiovascular disease occurring as a side effect of chemotherapy and radiotherapy. Both cancer treatment modalities can cause cardiac dysfunction, a major cause of morbidity and mortality in the oncologic population. It is necessary to periodically monitor cancer patients under treatment, especially those receiving anthracyclines and trastuzumab (monoclonal antibody), using mainly 3D echocardiography to calculate left ventricular ejection fraction and to estimate myocardial deformation...

This paper presents the design, fabrication and characterization of a miniature PZT-on-CMOS matrix transducer for real-time pediatric 3-dimensional (3D) transesophageal echocardiography (TEE). This 3D TEE probe consists of a 32 × 32 array of PZT elements integrated on top of an Application Specific Integrated Circuit (ASIC). We propose a partitioned transmit/receive array architecture wherein the 8 × 8 transmitter elements, located at the centre of the array, are directly wired out and the remaining receive elements are grouped into 96 sub-arrays of 3 × 3 elements...

The percutaneous MitraClip system is a catheter-based device designed to perform edge-to-edge mitral valve (MV) leaflet repair at the site of regurgitation. MitraClip implantation is an alternative procedure in patients at high surgical risk with symptomatic severe mitral regurgitation (MR) who are not candidates for MV repair/replacement due to their degree of comorbidity and associated high mortality risk. The procedure is guided by 3-dimensional (3D) transesophageal echocardiography (TEE) and fluoroscopy...

BACKGROUND: Given that in patients with cardiac amyloidosis (CA), deposition of amyloid protein is not restricted to the left ventricular (LV) myocardium, it can be hypothesized that the diagnostic value of deformation mechanics would be enhanced by considering right ventricular (RV) strain measures. The aim of the present study was to examine the potential utility of left ventricular (LV) and right ventricular (RV) deformation and rotational parameters derived from three-dimensional speckle-tracking echocardiograph (3DSTE) to diagnose cardiac amyloidosis and differentiate this disease from other forms of myocardial hypertrophy...

BACKGROUND: Epicardial adipose tissue (EAT) is a metabolically active visceral fat depot. Although EAT volume is associated with the incidence and burden of atrial fibrillation (AF), its role in subclinical left atrial (LA) dysfunction is unclear. This study aims to evaluate the relationships between EAT volumes, LA function, and LA global longitudinal strain. METHODS: One hundred and thirty people without obstructive coronary artery disease or AF were prospectively recruited into the study in Australia and underwent cardiac computed tomography and echocardiography...

Preservation of native left ventricular (LV) function in patients supported with LV assist device (LVAD) may be beneficial to attain optimal hemodynamics and enhance potential recovery. Currently, LVAD speed optimization is based on hemodynamic parameters, without considering residual native LV function. We hypothesized that alternatively, LV rotational mechanics can be quantified by 3D echocardiography (3DE), and may help preserve native LV function while optimizing LVAD speed. The goal of this study was to test the feasibility of quantifying the effects of LVAD implantation on LV rotational mechanics and to determine whether conventional speed optimization maximally preserves native LV function...

Percutaneous edge-to-edge repair using MitraClip® (Abbott Laboratories, Abbott Park, IL, USA) can be used to treat mitral regurgitation. However, real-time echocardiographic guidance is vital; and use of 3D transoesophageal echocardiography to guide the procedure has improved reproducibility, reliability and safety. This review describes the MitraClip® device - which is composed of a steerable guide catheter (SGC) and a Clip Delivery System (CDS) - and the MitraClip® procedure. The procedure consists of six steps: (1) transseptal approach and puncture; (2) introduction of the SGC into the left atrium; (3) navigation with the CDS into the left atrium to place the MitraClip® above the mitral valve; (4) crossing the valve and advancing the CDS into the left ventricle; (5) grasping the leaflets and assessment of the quality of the grasping; and (6) final mitral regurgitation assessment...

The mitral valve remains a complex structure where multiple forms of pathology can be seen. Mitral regurgitation continues to be one of the most common valvular diseases in the industrialized world. While intraoperative 2-dimensional transesophageal echocardiography has been commonplace for some time, 3-dimensional technology has emerged and has shown great benefit for diagnosis and guidance during mitral valve surgery. In the hands of a trained sonographer, high-quality real-time images can easily be obtained and correlate well with gross anatomical findings...
