The mitral valve orifice area (MVOA) is difficult to assess accurately by 2D echocardiography because of geometric assumptions, therefore 3D planimetry may offer advantages. We studied differences in MVOA measurements and prediction of clinical outcomes between 2D and 3D methods. Methods This was a head to head comparison of the most commonly used techniques to grade mitral stenosis (MS) by orifice area. 2D measurements (pressure half-time (PHT), planimetry) and 3D planimetry were performed retrospectively on patients with at least mild MS...

A 42-year-old intravenous drug user presented with sepsis and multiple brain and systemic emboli. Blood cultures were positive for Staphylococcus aureus. Transoesophageal echocardiography showed two masses in the left and the right ventricle. The LV mass was large (2.3x1.5cm), irregular, mobile and attached to the basal anterolateral LV segment, abutting but not involving the mitral valve. (Figure 1, Video 1). The RV mass was smaller (1.7x1.5 cm) irregular and mobile, possibly involving the subvalvular apparatus but not encroaching the tricuspid valve (Figure 2)...

A 42 year old male was admitted with shortness of breath secondary to suspected heart failure and chest infection. An echocardiogram revealed a dilated and impaired left ventricle; ejection fraction 29%, with a large, mobile thrombus within the left ventricular apex. Due to the presence of liver dysfunction, vitamin K antagonists were deemed inappropriate, thus the decision was taken to use the novel anticoagulation agent Apixaban. After six days of receiving Apixaban, a cardiac magnetic resonance scan was preformed which showed complete resolution of the LV apical thrombus...

Non-atherosclerotic myocardial infarction (MI) is an important but often misdiagnosed cause of acute MI. Furthermore, non-atherosclerotic MI with concomitant acute stroke and pulmonary embolism due to in-transit thrombus across a patent foramen ovale (PFO) is a rare but potentially fatal combination (1-3). Early detection of this clinical entity can facilitate delivery of targeted therapies and avoid poor outcome (1, 2). Here, we describe a 68-year-old female with hypertension, tobacco abuse, and chronic obstructive pulmonary disease presenting with facial droop, right arm weakness and aphasia...

REVIEW
Neil David Hauser, Justiaan Swanevelder
Trans-oesophageal echocardiography (TOE) has become an almost universal intraoperative monitor and diagnostic tool. The use of TOE in most cardiac, aortic, major vascular and transplant operations is used to aid anaesthetic management as well as assist surgical decision-making. In addition to the perioperative environment it is increasingly being used in the Outpatient Department, Emergency Department and Intensive Care settings. In this review we consider the safety associated with the use of TOE, we review the suggested contra-indications and areas that we would consider to TOE to be a necessity...

A 42-year-old intravenous drug user presented with seizures and septicaemia. CT and MRI were suggestive of multiple brain and systemic emboli, and blood and CSF cultures were positive for Staphylococcus aureus. Initial transthoracic echocardiogram did not show any abnormalities but subsequent transoesophageal echocardiography showed two masses in the left and the right ventricle. The LV mass was large, irregular, non-mobile and attached to the basal anterolateral LV segment abutting but not involving the mitral valve...

Introduction: Hand-held imaging devices are widely used in clinical practice and are a useful tool. There is no published review examining the diagnostic parameters achieved with these devices in clinical practice. Methods: We searched three online medical literature databases (PubMed, EMBASE and MEDLINE) for all literature published up until January 2018. We selected studies that (1) were conducted in the adult population; (2) used a truly hand-held device; (3) featured sensitivities and/or specificities on the use of the hand-held scanner...

Background: The mitral valve orifice area (MVOA) is difficult to assess accurately by 2D echocardiography because of geometric assumptions; therefore, 3D planimetry may offer advantages. We studied the differences in MVOA measurements between the most frequently used methods, to determine if 3D planimetry would result in the re-grading of severity in any cases, and whether it was a more accurate predictor of clinical outcomes. Methods: This was a head-to-head comparison of the three most commonly used techniques to grade mitral stenosis (MS) by orifice area and to assess their impact on clinical outcomes...

Transoesophageal echocardiography (TOE) has, in certain clinical situations, become an almost universal monitor and diagnostic tool. In the perioperative environment, TOE is frequently used to guide anaesthetic management and assist with surgical decision making for, but not limited to, cardiothoracic, major vascular and transplant operations. The use of TOE is not limited to the theatre environment being frequently used in outpatient clinics, emergency departments and intensive care settings. Two case reports, one of oesophageal perforation and another of TOE utilization in a patient having previously undergone an oesophagectomy, introduce the need for care while using TOE and highlight the need for vigilance...

LETTER
Keith Pearce, John Chambers
Dr Porter in his editorial comment (1) on a physiologist-led stress echo service (2) acknowledges that the service was safe in terms of adverse effects but is concerned that ‘the interpretation of the study was also done by the cardiac physiologist’. He reminds us ‘that the biggest danger associated with dobutamine stress echocardiography is in misinterpreting the data obtained…’.

A 77-year-old male underwent elective bioprosthetic aortic valve replacement (23 mm Carpentier-Edwards Perimount MagnaEase) for severe aortic stenosis. His pre-discharge transthoracic echocardiogram (TTE) was normal. He presented 9 days after surgery with dyspnea and fever. He was in sinus rhythm. Blood cultures were taken and he was commenced on empirical antibiotics for possible infective endocarditis (subsequently all negative). Repeat TTE showed a well-seated prosthesis without regurgitation but elevated gradients (peak/mean gradients 69/48mmHg respectively)...

Summary: We present the case of a 32-year-old man who presented with a remote history of chest pain and was diagnosed with non-compaction cardiomyopathy on echocardiography. On presentation, he was relatively asymptomatic with normal cardiac function. Unfortunately, he presented 1 year later with a catastrophic embolic stroke. Learning points: Left ventricular non-compaction (LVNC) is a myocardial disorder characterised by prominent left ventricular (LV) trabeculae, a thin compacted layer and deep intertrabecular recesses...

Summary: Thirty-seven-year-old male presented with cough, dyspnea, significant weight loss (20 kg) and subacute fever for the past 2 months. Physical examination revealed inspiratory and expiratory wheezing bilaterally. A normal S1, S2 and a 3/6 systolic ejection murmur at the left upper parasternal border with respiratory variation were found during cardiac auscultation. Kidney and bone marrow biopsy reported a high-grade B-cell lymphoma. Echocardiography and cardiac CT findings consisted of multiple intracardiac masses affecting the right ventricular (RV) outflow track, RV apex, medial portion of the right atrium and posterior left atrium, as well as mild impairment of the RV systolic function...

International best practice guidelines recommend lifelong follow-up of patients that have undergone valve repair or replacement surgery and provide recommendations on the utilization of echocardiography during follow-up. However, such follow-up regimes can vary significantly between different centres and sometimes within the same centre. We undertook this study to determine the patterns of clinical follow-up and use of transthoracic echocardiography (TTE) amongst cardiologists in a large UK tertiary centre...

Background: Dobutamine stress echocardiography (DSE) services have traditionally been medically led. In some UK institutions, DSE lists are led by physiologists with medical support. In our tertiary cardiac centre at New Cross Hospital (NCH), the DSE service was established by a consultant echocardiographer. Following intensive training and assessment, the Trust approved drug administration by named senior cardiac physiologists. We believe this is the first report of a cardiac physiologist-managed DSE service, including physiologist drug administration...

Objective: The left atrium (LA) is exposed to left ventricular pressure during diastole. Applying the 2016 American Society of Echocardiography left ventricular diastolic function (LVDF) guidelines, this study aims to investigate whether left atrial ejection fraction (LAEF) and left atrial active emptying fraction (LAAEF) are markers of diastolic dysfunction (LVDD). Methods: Retrospective cohort of consecutive patients (n = 124) who underwent transthoracic echocardiography were studied...

Various metrics have been used in curriculum-based transesophageal echocardiography (TEE) training programs to evaluate acquisition of proficiency. However, the quality of task completion, that is the final image quality, was subjectively evaluated in these studies. Ideally, the endpoint metric should be an objective comparison of the trainee-acquired image with a reference ideal image. Therefore, we developed a simulator-based methodology of preclinical verification of proficiency (VOP) in trainees by tracking objective evaluation of the final acquired images...
