A Caucasian male triathlete and previous soccer player in his early thirties presented for further evaluation post out-of-hospital cardiac arrest and implantation of a transvenous single-chamber implantable cardioverter-defibrillator (ICD) (Figure 1). He originally presented with chest pain and ventricular ectopy with no family history of sudden cardiac death or inherited cardiac disease. Question: The findings were consistent with pathological characteristics of arrhythmogenic cardiomyopathy (ACM) with biventricular involvement. Diagnosis was made considering the 2010 Task Force criteria and the 2020 International criteria (Padua criteria).1, 2 The 12-lead ECG showed sinus bradycardia (50 bpm), T-wave inversion in the inferior leads (II, III, and aVF) with isoelectric J-points and ST segments and low QRS voltage criteria in the limb leads (Figure 1A). Poor anterior R-wave progression and prolonged terminal activation duration (V2) were also present. The transthoracic echocardiogram (ECHO) demonstrated normal left ventricle (LV) size with low normal systolic function (EF 52%) (Video 1). However, strain imaging was abnormal, with reduced LV epicardial and mid layer-specific global longitudinal peak systolic strain (GLPSS) (−11% and −13.2%) (Figure 1C), prolonged mid-wall LV mechanical dispersion (60 ms) and post-systolic shortening in the basal segments (Figure 2—arrows). The right ventricle (RV) was normal in size with reduced systolic function (RV FAC 34%), with a dyskinetic RV apex (Figure 1B) (Video 2). RV deformation patterns showed early systolic lengthening and post-systolic shortening of the apex (Figure 3—arrows). Prior to ICD implantation, cardiac magnetic resonance (CMR) demonstrated extensive circumferential, intramural and subepicardial late gadolinium enhancement (LGE) of the LV (nonischaemic pattern) (Figure 1D). Genotyping revealed a heterozygous pathogenic (ACMG class 5) missense desmin (DES) gene variant: c.1205T>C, p.(IIe402Thr). Family screening of his asymptomatic sister in her late twenties showed a mildly dilated RV with apical dyskinesis on cardiac imaging. ACM is a genetic disease characterised by progressive fibrofatty tissue replacement of the myocardium, with greater exercise exposure associated with LV involvement and systolic dysfunction.2, 3 CMR imaging is considered the gold standard for the characterisation of tissue, with the detection and quantification of myocardial fibrosis (MF) using gadolinium. MF is associated with increased myocardial stiffness, heart failure, a higher incidence of ventricular arrhythmias (VA), and adverse cardiac outcomes such as sudden cardiac death.4 Tissue characterisation with the use of 2D strain imaging on ECHO and CMR can help in the distinction of different ACM phenotypes and identify subclinical disease.5, 6 Studies have shown that 2D strain imaging including layer-specific GLPSS and LV mechanical dispersion may help identify ACM patients with high-risk arrhythmic features such as

Caesarean scar pregnancy (CSP), if not managed timely, can result in pre‐term labour, postpartum haemorrhage, hysterectomy or maternal and fetal death. This study aims to compare the diagnostic performances of different sonographic features recommended in various good practice recommendations and literature; then propose an algorithm that could aid in easier identification of CSP using transvaginal ultrasound.A retrospective review of ultrasound images of intrauterine pregnancy (IUP) and CSP between 4.9 and 11.9 weeks gestation was conducted. The diagnostic performance of the Royal College of Obstetricians & Gynaecologists (RCOG) guideline, Timor‐Tritsch et al. (TT) method and combined method were evaluated. An algorithm was then created to calculate a numerical value for diagnosis. The methods were tested for intra‐ and inter‐observer agreement.A total of 66 ultrasound cases (30 IUP and 36 CSP) were included in this study. The sensitivity of the RCOG guideline, TT method and combined method were 58.3%, 94.4% and 100% while the specificity were 96.7%, 90% and 90%, respectively. The TT method and combined method performed significantly better than the RCOG guideline (p = .0016 and .0002, respectively). Using the proposed algorithm, a value larger or equal to 52.2 gave 97.2% sensitivity and 93.3% specificity that CSP is present. Intra‐ and inter‐observer agreement for all methods were moderate to almost perfect.Screening during early first trimester is important to improve the diagnostic accuracy of CSP. The TT method is a good supplement to the RCOG guideline. The proposed algorithm is a useful tool to improve diagnostic accuracy and confidence.

Transient perivascular inflammation of the carotid artery (TIPIC) syndrome is a rare cause of atypical neck pain. The etiology of TIPIC is not fully known and is characterized by transient inflammation around the carotid artery. Ultrasonography (US) and especially magnetic resonance imaging (MRI) are the most important evaluation methods in the diagnosis and follow‐up of the disease. In this article, we report a 25‐year‐old male patient who presented with unilateral neck pain and was diagnosed with TIPIC in the light of his clinical and radiological findings.

The sural nerve is a sensory nerve which innervates the posterolateral distal calf and lateral foot. It can be demonstrated using high resolution ultrasound and travels near the small saphenous vein throughout most of its course. There are variations in its origin and relative position through the posterior distal calf, lateral ankle, and foot. To allow this nerve and any potential pathology or injury to be sonographically demonstrated, a good understanding of the sonographic relative anatomy, course, and common anatomical variations, as well as the sonographic normal appearances throughout need to be appreciated and these are reviewed in this paper.

Asynchrony is a frequent problem in critical care units, being underdiagnosed by the treating team and often requiring advanced monitoring equipment for its detection. Ultrasonography of the diaphragm allows direct observation, in real time, of muscle displacement and its synchronization with the ventilator waveforms, which results in a promising tool for interpreting difficult to diagnose asynchronies.

An atrioventricular septal defect (AVSD) is diagnosed with prenatal sonography using the 4‐chamber view (4CV) of the fetal heart. Prenatal 2D sonographic imaging of normal and AVSD short axis (SAX) atrioventricular (AV) valve views have not been well described. The aim is to describe the 2D sonographic 4‐chamber and SAX view of the AV valves when an AVSD is present compared to normal AV valves. The 4CV AVSD heart demonstrates no offset of AV valves due to the abnormal valve structure. Complete and intermediate AVSD has a septum primum defect and inlet ventricular septal defect (VSD). The partial AVSDs have either a septum primum defect or just an inlet VSD with an intact primum septum. The SAX view of AVSD demonstrates the common AV junction and the bridging leaflets. In ventricular diastole valves have a “figure 8” and “dumbbell” shape in partial and complete AVSD, respectively. These appearances are not seen in the normal heart in SAX as both tricuspid and mitral valve are separate valves. The SAX view can be obtained by locating a sagittal aortic arch view and then scanning slightly towards the left side of the fetus, near the base of the heart and the AV valves. An in‐depth interrogation of the abnormal fetal heart is obtained without specialised 4D capable ultrasound machines providing information to assist in counselling during the pregnancy and for postnatal surgical planning. Future research to assess the feasibility of incorporating the SAX view into routine practice and by general sonographers is suggested.

A request for an ultrasound of the eye can be a relatively infrequent occurrence for a sonographer, but ultrasound can play a pivotal role in the detection of vision threatening conditions. In those instances where sonographers are required to perform the occasional ocular ultrasound, a sound knowledge of normal anatomy, scanning techniques, technical parameters and pitfalls is pertinent to ensure pathology is not overlooked. Ultrasound of the eye is commonly performed following trauma or visual disturbance. As such it is a useful diagnostic tool when fundoscopic examination of the eye is limited. The fact that it lacks the use of ionizing radiation, is non‐invasive and readily accessible are just some of its many advantages. However, the greatest advantage is its ability to provide a dynamic assessment of the eye. Ocular structures have a higher sensitivity to ultrasound exposure, which necessitates the correct use of technical parameters so as to not induce any vision affecting biological effects. The purpose of this article is to introduce sonographers to normal ocular anatomy, optimal scanning techniques for enhanced pathology detection, and most importantly the safe use of physical parameters to minimize damage to sensitive ocular structures.
