BACKGROUND: Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) play important roles in diagnosis and management of cardiac diseases. However, the issue of the accuracy and reliability of LVEF and GLS remains to be solved. Image quality is one of the most important factors affecting measurement variability. The aim of this study was to investigate whether improved image quality could reduce observer variability. METHODS: Two sets of three apical images were acquired using relatively old- and new-generation ultrasound imaging systems (Vivid 7 and Vivid E95) in 308 subjects...

REVIEW
Antigoni Deri, Kate English
This review article will guide the reader through the basics of echocardiographic assessment of congenital left to right shunts in both paediatric and adult age groups. After reading this article the reader will understand the pathology and clinical presentation of atrial septal defects (ASDs), ventricular septal defects (VSDs), atrioventricular septal defects (AVSDs) and patent ductus arteriosus (PDA). In times gone by the stethoscope was the primary diagnostic tool used to diagnose these lesions, but in today's clinicians those skills have been usurped by the superiority of the trans-thoracic echo probe...

This study sought to examine layer-specific longitudinal and circumferential systolic and diastolic strain, strain rate (SR) and diastolic time intervals in hypertensive patients with and without diastolic dysfunction. Fifty-eight treated hypertensive patients were assigned to normal diastolic function (NDF, N=39) or mild diastolic dysfunction (DD, N=19) group. Layer-specific systolic and diastolic longitudinal and circumferential strains and SR were assessed. Results showed no between group difference in left ventricular mass index (DD: 92...

Stress echocardiography is a widely utilised test in patients with known or suspected coronary artery disease (CAD), valvular heart disease and cardiomyopathies. Its advantages include the ubiquitous availability of echocardiography, lack of ionising radiation, choice of physiological or pharmacological stressors, good diagnostic accuracy and robust supporting evidence base. SE has evolved significantly as a technique over the past three decades and has benefitted considerably from improvements in overall image quality (superior resolution), machine technology (e...

INTRODUCTION: We compared right and left ventricular cardiac output (RVCO and LVCO) in fetuses of diabetic mothers (FDM) to a large normal cohort. METHODS: We prospectively enrolled 264 normal fetuses and 30 FDM. Fetal CO parameters: semilunar valve velocity time integrals (AVVTI, PVVTI), ventricular outflow diameters (LVOTD, RVOTD), stroke volumes (AVSV, PVSV) were measured, and LVCO and RVCO calculated.  These were normalized using nonlinear regression to estimated fetal weight (EFW) to provide means and standard deviations...

BACKGROUND: Left ventricular (LV) function is dependent on load, intrinsic contractility and relaxation with a variable impact on specific mechanics. Strain (ε) imaging allows the assessment of cardiac function however the direct relationship between volume and strain is currently unknown. The aim of this study was to establish the impact of preload reduction through head-up tilt (HUT) testing on simultaneous left ventricular (LV) longitudinal and transverse function and their respective contribution to volume change...

We present a 73 years old woman who presented with pelvic cancer, ongoing sepsis and presumably a new diastolic murmur. Her transthoracic echocardiogram, as part of a sepsis screen, showed an abnormal pulmonary valve with moderate regurgitation. Trans-oesophageal echocardiography using 3D imaging showed a bicuspid pulmonary valve as the cause for the moderate regurgitation, but with no clear source of infection. Bicuspid pulmonary valve as an isolated clinical entity is a rare finding in clinical practice. Bicuspid pulmonary valves tend to be more commonly associated with other congenital cardiac anomalies...

A 63 year old female presented to hospital with progressive exertional dyspnoea over a 6 month period. In the year preceding her admission, she reported an intercurrent history of abdominal pain, diarrhoea and weight loss. She was found to be hypoxic, the cause for which was initially unclear. A ventilation-perfusion scan identified a right-to-left shunt. Transoesophageal echocardiography (TOE) demonstrated a significant right-to-left intracardiac shunt through a patent foramen ovale (PFO); additionally severe tricuspid regurgitation was noted through a highly abnormal tricuspid valve...

OBJECTIVE: Patients with non-ischaemic systolic heart failure (HF) and idiopathic dilated cardiomyopathy (DCM) are a heterogenous group with varied morbidity and mortality. Prognostication in this group is challenging. We performed a systematic review and meta-analysis to examine the significance of the presence of contractile reserve as assessed via stress imaging on mortality and hospitalisation. METHODS: A search for studies that non-invasively assessed contractile reserve in patients with DCM or non-ischaemic HF with reduced ejection fraction; stress imaging with follow up data comparing outcomes...

BACKGROUND: We sought to assess the long-term evolution of left ventricular (LV) function using two-dimensional (2D) and three-dimensional (3D) speckle tracking echocardiography (STE) for the detection of preclinical diabetic cardiomyopathy, in asymptomatic type 1 diabetic patients, over a 6-year follow-up. DESIGN AND METHODS: Sixty-six asymptomatic type 1 diabetic patients with no cardiovascular risk factors were compared to 26 matched healthy controls. Conventional, 2D and 3D-STE were performed at baseline...

This case describes an iatrogenic cause of heart failure: the pacemaker syndrome. The diagnosis was initially overlooked but in retrospect could have easily been made by reviewing the rhythm strip recorded during the echocardiogram. The patient eventually received the correct treatment to restore atrioventricular synchrony and experienced rapid resolution to her disabling symptoms. LEARNING POINTS: New-onset heart failure following a pacemaker implant should be evaluated with an echocardiogram...

BACKGROUND: While transcatheter aortic valve implantation (TAVI) has traditionally been supported intraprocedurally by transoesophageal echocardiography (TOE), transthoracic echocardiography (TTE) is increasingly being used. We evaluated echocardiographic imaging characteristics and clinical outcomes in patients who underwent TTE during TAVI (TTE-TAVI). METHODS AND RESULTS: A select team of dedicated sonographers and interventional echocardiographers performed TTE-TAVI in 278 patients, all of whom underwent TAVI through transfemoral access...

This case report highlights the utility of paravertebral (PV) imaging in the diagnosis of aortic dissection, the evaluation of left ventricular systolic function and drawing the distinction between pleural and pericardial effusions. In this case, less attenuation of the ultrasound beam, reduced lung viscosity due to pleural effusions and less impedance mismatch between media led to images of superior quality and high diagnostic value. This supports the use of paravertebral imaging as an adjunct to conventional echocardiography windows, particularly when conventional transthoracic imaging proves challenging...

A 54-year-old male developed a left ventricular pseudoaneurysm (Ps) along the lateral wall of the left ventricle (LV), which was diagnosed incidentally by two-dimensional transthoracic echocardiography (2DTTE) 6 months after an acute myocardial infarction. Color flow imaging (CFI) showed blood flow from the LV into the aneurysmal cavity and invasive coronary angiography revealed sub-occlusion of the circumflex artery. A complementary study using cardiovascular magnetic resonance (CMR) confirmed a dilated left ventricle with depressed ejection fraction, thin dyskinetic anterolateral and inferolateral walls, a Ps adjacent to the lateral wall of the LV contained by the pericardium and blood passing in and out through a small defect in the LV mid-anterolateral wall...

BACKGROUND: Several studies have reported the accuracy and reproducibility of HeartModel for automated determination of three-dimensional echocardiography (3DE)-derived left heart volumes and left ventricular (LV) ejection fraction (LVEF) in adult patients. However, it remains unclear whether this automated adaptive analytics algorithm, derived from a 'training' population, can encompass adequate echo images in Chinese adolescents. OBJECTIVES: The aim of our study was to explore the accuracy of HeartModel in adolescents compared with expert manual three-dimensional (3D) echocardiography...
