#1
Ramasamy Manivarmane, Rebecca Taylor, Rajdeep Khattar
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...

A 25-year-old male with a background of ulcerative colitis presented with a two-week history of central chest pain. His ECG on presentation showed global T wave inversion with a peak troponin I of 165 ng/ml. Clinical diagnosis of myopericarditis/myocarditis was made. Echocardiography and cardiac MR confirmed the diagnosis. On detailed assessment of his medication history, mesalazine was suspected as an aetiological factor, with discontinuation resulting in an improvement in symptoms, inflammatory markers and cardiac enzymes...

We present a rare complication of deep venous thrombosis with pulmonary embolism that threatened the patient with systemic embolization. A 36-year-old female was referred to the hospital after five days of progressive shortness of breath and chest pain. Preceding onset of symptoms she had undergone surgery leading to reduced physical activity and had just returned from vacation by a long flight. Investigations with transthoracic and transesophageal echocardiography revealed a thromboembolism-in-transit across a patent foramen ovale...

A 54-year-old man 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. Colour 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: 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...

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...

We present the case of a previously fit 84-year-old female with long-standing systemic hypertension and the echo phenotype of hypertrophic cardiomyopathy (HCM) - asymmetrical septal hypertrophy, significant resting left ventricular (LV) outflow obstruction and mitral regurgitation (MR) secondary to systolic anterior motion (SAM) of the mitral valve. Valsalva provocation caused an increase in LVOT dynamic gradient and MR severity. The patient presented with a progressive decrease in exercise capacity along with chest pain relieved by rest or sublingual GTN...

76 year old female presented following an episode of collapse. She was hypotensive with the paramedics and remained refractory despite fluid resuscitation. Her initial baseline tests revealed an elevated troponin; she subsequently underwent a coronary angiogram which showed mild coronary artery disease. Left ventriculogram was performed which showed abnormal mid-wall ballooning and severely impaired systolic function, characteristic of takotsubo syndrome. Echocardiogram confirmed presence of diagnosis and presence of left ventricular outflow tract obstruction with high gradient...

EDITORIAL
Cheuk-Man Yu
The advancement of echocardiography in the past two decades is more than downsizing of the machines and improvement of image quality, but introduction of new imaging modalities leading to the ability of performing quantitative analysis. This function is greatly facilitated by the integration of echo machines with high performance computers, software programming and establishment of workstation for offline analysis. Today, echo examination is more than estimation of ejection fraction (EF) and patterns of left ventricular (LV) diastolic dysfunction...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

Trans-oesophageal echocardiography (TOE) is frequently performed prior to atrial fibrillation (AF) ablation to exclude left atrial appendage (LAA) thrombus. However, patients undergoing AF ablation are usually anticoagulated, thus making the presence of thrombus unlikely in most cases. This study aimed to determine whether the CHA2DS2VASc scoring system can be used to identify patients that do not require TOE prior to AF ablation. In this single centre retrospective study, local institutional and primary care databases and electronic patient records were searched to identify patients that had undergone TOE prior to AF ablation...

REVIEW
L D Hunter, M Monaghan, G Lloyd, A J K Pecoraro, A F Doubell, P G Herbst
This focused review presents a critical appraisal of the World Heart Federation criteria for the echocardiographic diagnosis of rheumatic heart disease (RHD) and its performance in African RHD screening programs. It identifies various logistical and methodological problems that negatively impact on the current guideline's performance. The authors explore novel RHD screening methodology that could address some of these shortcomings and if proven to be of merit, would require a paradigm shift in the approach to the echocardiographic diagnosis of subclinical RHD...
