Three-Dimensional echocardiography in congenital heart disease

We aimed to evaluate clinical and prognostic significance of myocardial work parameters of the systemic right ventricle (SRV). Thirty-eight patients with the SRV underwent echocardiographic assessment of the SRV systolic function including 3D-echocardiography derived ejection fraction, 2D longitudinal strain and myocardial work analysis. The study endpoint was the combination of all-cause mortality and heart transplantation. Global constructive work (GCW) and global work index (GWI) demonstrated moderate correlation with the 3DE-derived SRV ejection fraction (EF) (Rho 0...

OBJECTIVE: The paper aimed to improve the accuracy limitations of traditional two-dimensional ultrasound and surgical procedures in the diagnosis and management of congenital heart disease (chd), and to improve the diagnostic and therapeutic level of chd. METHOD: This article first collected patient data through real-time imaging and body surface probes, and then diagnosed 150 patients using three-dimensional echocardiography. In order to verify the effectiveness of the combination therapy, 60 confirmed patients were divided into a control group and an experimental group...

Accurate knowledge of right ventricle (RV) volumes and ejection fraction is fundamental to providing optimal care for pediatric patients with congenital and acquired heart disease, as well as pulmonary hypertension. Traditionally, these volumes have been measured by cardiac magnetic resonance (CMR) because of its accuracy, reproducibility, and freedom from geometric assumptions. More recently, an increasing number of studies have described the measurement of RV volumes by three-dimensional echocardiography (3DE)...

BACKGROUND: Tricuspid valve agenesis is an exceptionally rare congenital cardiac disease characterized by the incomplete formation or complete absence of one or more tricuspid leaflets. It is commonly diagnosed during childhood due to the development of heart failure symptoms. CASE SUMMARY: We report the case of a 62-year-old woman admitted for a worsening of heart failure symptoms (New York Heart Association functional Class IV at admission). A standard transthoracic echocardiogram was performed, which showed severe right heart dilatation and severe tricuspid regurgitation...

Echocardiography is a fundamental component of pediatric cardiology, and appropriate indications have been established for its use in the setting of suspected, congenital, or acquired heart disease in children. Since the publication of guidelines for pediatric transthoracic echocardiography in 2006 and 2010, advances in knowledge and technology have expanded the scope of practice beyond the use of traditional modalities such as two-dimensional, M-mode, and Doppler echocardiography to evaluate the cardiac segmental structures and their function...

BACKGROUND: Aorto-left ventricular tunnel (ALVT) is a paravalvular communication between aorta and left ventricle. It is one of the rare congenital heart diseases which could present with heart failure. CASE PRESENTATION: A case of ALVT was diagnosed in infancy. Preliminary assessment was possible using conventional echocardiography; however, functional assessment and accurate anatomy of ALVT were further verified via variable imaging modalities starting from speckle tracking and three-dimensional echocardiography to cardiac CT angiogram...

A comprehensive and structured imaging approach in the evaluation of the systemic right ventricle (sRV) in patients with complete transposition of the great arteries (TGA) after atrial switch procedure and congenitally corrected transposition of the great arteries (ccTGA) is a key for their optimal lifelong surveillance. Despite the improvements in cardiovascular imaging of adults with congenital heart disease (ACHD), the imaging of sRV remains an ongoing challenge due to its complex morphology and the difficulty in applying the existing knowledge for the systemic left ventricle...

The initial means of detecting right ventricular (RV) dilatation is often transthoracic echocardiography (TTE), and once the presence of RV dilatation is suspected, there is the possibility of RV volume overload, RV pressure overload, RV myocardial disease, and even nonpathological RV dilatation. With respect to congenital heart disease with RV volume overload, defects or valvular abnormalities can be easily detected with TTE, with the exception of some diseases. Volumetric assessment using three-dimensional echocardiography may be useful in determining the intervention timing in these diseases...

Three-dimensional (3D) modeling and printing is an emerging technology in veterinary cardiovascular medicine allowing the fabrication of anatomically correct patient-specific models. These patient-specific models can be used for a wide range of purposes including medical teaching, assessment of cardiac function and movement of valve leaflets, design and assessment of devices created for interventional procedures, and pre-surgical planning [1-3]. Additionally, these 3D models can facilitate communication between the clinical team and the patient's owner...

BACKGROUND: Atrioventricular valve regurgitation (AVVR) is a devastating complication in children and young adults with congenital heart disease (CHD), particularly in patients with single ventricle physiology. Transcatheter edge-to-edge repair (TEER) is a rapidly expanding, minimally invasive option for the treatment of AVVR in adults that avoids the morbidity and mortality associated with open heart surgery. However, application of TEER in in CHD and in children is quite novel. We describe the development of a peri-procedural protocol including image-derived pre-intervention simulation, with successful application to four patients...

AIMS: Pediatric transoesophageal echocardiography (TOE) probes have remained two-dimensional (2D) limiting their use compared to adults. While critical in pediatrics for interventions and post-surgery assessments, technological advancements introduced a three-dimensional (3D) pediatric TOE probe. This study assessed the new 3D pediatric TOE probe (GE 9VT-D) for feasibility, handling, and imaging quality. METHODS AND RESULTS: At Children's Hospital of Toulouse, 2-month prospective study enrolled children undergoing TOE with the new probe...

Double orifice mitral valve (DOMV) is an extremely rare congenital anomaly of the mitral valve (MV) wherein the MV orifice divides into two separate orifices by an accessory fibrous band.Isolated DOMV is a rarity and is often discovered incidentally. It may be associated with other congenital conditions wherein it is identified in early childhood. Its prevalence and prognostic relevance in adulthood remain unclear. DOMV patients may be asymptomatic or have symptoms due to mitral stenosis or regurgitation. We present a case of an asymptomatic young adult initially diagnosed with rheumatic mitral stenosis...

BACKGROUND: Interrupted aortic arch (IAA) is a rare congenital heart disease characterized by loss of continuity between the ascending and the descending aorta. Prenatal diagnosis of IAA by echocardiography is challenging but nonetheless can be accomplished via a systematization of cardiac fetal evaluation. CASE PRESENTATION: We report a case of fetal IAA type A prenatally diagnosed through two-dimensional echocardiography using both a three vessel-trachea view and a sagittal view...

The unique imaging capabilities of transesophageal echocardiography (TEE) make it a valuable tool for characterizing the structure and function of the heart and for providing procedural monitoring. With the creation of new devices and expansion of procedural options with increased applications, multiplanar and three-dimensional imaging with TEE can be essential for clinical decision making. A description of the indications and clinical application of TEE in animals while highlighting probe characteristics, limitations and patient safety are the focus of this review...

The purpose of this article is to describe the evaluation of a variety of congenital heart diseases (CHDs) using three-dimensional (3D) ultrasound with different software, such as Cristal Vue, Realistic Vue, LumiFlow, and Spatiotemporal Image Correlation (STIC), with HDlive and HDlive Flow Silhouette modes. These technologies provide realistic images of the fetal heart and cardiac vessels using a fixed virtual light source that allows the operator to freely select a better light source position to enhance the cardiovascular anatomical details...

This study aimed to evaluate the anatomical reproducibility of a preoperative intracardiac 3D image (IC image) created using computed tomography, and to investigate its usefulness as a surgical decision-making tool. Between 2012 and 2022, ventricular septal defect (VSD) patients, and double outlet right ventricle (DORV) or transposition of the great arteries (TGA) with pulmonary stenosis (PS) patients who underwent cardiac surgery and had preoperative computed tomography were enrolled. SYNAPSE VINCENT® (Fujifilm) was used to create an IC image which was analyzed retrospectively...

BACKGROUND: The dynamic shape of the normal adult mitral annulus has been shown to be important to mitral valve function. However, annular dynamics of the healthy mitral valve in children have yet to be explored. We sought to model and quantify the shape and major modes of variation of pediatric mitral valve annuli at four phases in the cardiac cycle using transthoracic echocardiograms. METHODS: The mitral valve annuli of 100 children and young adults with normal 3D echocardiograms were modeled in four different cardiac phases using the SlicerHeart extension for 3DSlicer...

Three-dimensional intracardiac echocardiography (3D ICE) has gained popularity in interventional cardiology given its improved spatial and temporal imaging in assessing intracardiac anatomy pre- and post-intervention. We describe the use of 3D ICE in the reduction of a Fontan fenestration with an Occlutech atrial flow regulator (AFR) device.

Double orifice mitral valve is a rare congenital anomaly that is often associated with other congenital cardiac abnormalities. Patients may present with valvular dysfunction or may be asymptomatic and have an incidental diagnosis of double outlet mitral valve. Whether symptoms due to this pathology are present or not it is important to accurately characterize this lesion. Three-dimensional imaging is a powerful diagnostic modality for diagnosing and characterizing lesions such as this as highlighted in this case image series where we describe how three-dimensional transesophageal echocardiography was utilized to characterize both complete and incomplete bridge type double orifice mitral valve...

Total anomalous pulmonary venous connection (TAPVC) is a critical congenital heart disease which is often missed on prenatal echocardiography because of the decreased pulmonary blood flow in fetal life. Improvement in technology has resulted in increasing prenatal diagnosis of this condition. We report a foetus with infra cardiac TAPVC in whom prenatal diagnosis was facilitated by the use of STIC technology.
