Wellens’ syndrome, characterised by specific T-wave changes on electrocardiogram (ECG), indicates critical proximal left anterior descending (LAD) stenosis and high acute myocardial infarction risk. While revascularisation is the standard treatment, it may be unsuitable for elderly patients with comorbidities. We present a case of successful medical management of Wellens’ syndrome type B in a 94-year-old woman deemed unfit for invasive interventions. The patient was treated with dual antiplatelet therapy, high-intensity statin, and anti-anginal medications. Symptom control was achieved, and serial ECGs and cardiac biomarkers remained stable. This case demonstrates that aggressive medical management can be a viable alternative in elderly patients with Wellens’ syndrome type B, unsuitable for invasive procedures....

Though a rare condition, acute type A aortic dissection (ATAAD) is associated with high morbidity and mortality; hence, timely diagnosis and surgery are important to reduce the risk of mortality. If the dissection extends into the aortic arch branches, ensuring adequate cerebral perfusion during surgery is crucial to preventing stroke. A 50-year-old man presented to the emergency department with symptoms of acute chest pain, dizziness, and headache. His blood pressure was 180/110 mmHg and heart rate was 100 bpm. He had a high blood pressure and heart rate and was initially treated with glyceryl trinitrate. Initial investigations ruled out acute coronary syndrome. Further investigations revealed ATAAD with the involvement of arch branches, an incomplete (open) circle of Willis and cerebral malperfusion. He was prepared for a branch-first total aortic arch replacement. Due to the high risk of stroke in this patient, off-pump axillo-axillary bypass (adaptive perfusion technique) was used to ensure bihemispheric cerebral perfusion throughout the surgery. The surgery was uneventful, and the patient was discharged 12 days later. Postoperative follow-up at six months was normal. In conclusion, ATAAD is a surgical emergency that can mimic other acute thoracic conditions, such as pulmonary embolism and acute coronary syndrome; therefore, a judicious approach should be applied in the diagnosis and early management of symptoms. The reconstruction technique should be tailored to the patient’s needs; as this patient had a poorly functioning circle of Willis and cerebral hypoperfusion, continuous bilateral cerebral perfusion was essential to prevent irreversible cerebral ischaemic insult. The adaptive technique is easy to learn for surgeons who are already proficient in aortic dissection procedures, it is reproducible and requires only minor changes to the surgical setup without any substantial increase in operative time. Adoption of this technique in other surgical centres could be beneficial in increasing the success rate for the treatment of ATAAD....

Pericardial cyst is a rare diagnosis, mainly considered a congenital condition. Most patients with pericardial cysts present without symptoms. Symptomatic presentation often relates to the size and location of the pericardial cyst. We report a case of a 49-year-old man who presented with subacute breathlessness in which the diagnosis of a pericardial cyst was made following various investigations – from transthoracic echocardiography and computed tomography scan to video-assisted thoracoscopic surgery biopsy, upon which a histological diagnosis was made. This case report reviews and discusses the available literature on the epidemiology and potential presenting features of a pericardial cyst, and the current recommended assessment and management strategies thereof. This case highlights the importance of effective multidisciplinary communication and joint input towards clinical decision-making, particularly in complex scenarios, to achieve optimal patient outcomes....

Coronary artery spasm (CAS), or Prinzmetal angina, is a recognised cause of myocardial ischaemia in non-obstructed coronary arteries which typically presents with anginal chest pain. This case report describes an atypical presentation of CAS in a 68-year-old white British male with cardiovascular risk factors. The patient presented with recurrent palpitations and pre-syncope, with no chest pain. Ambulatory electrocardiography (ECG) monitoring revealed recurrent polymorphic ventricular tachycardia (PMVT). Coronary angiography identified moderate stenosis of the right coronary artery (RCA), without significant flow restriction by invasive pressure wire interrogation. Inpatient monitoring revealed episodes of recurrent PMVT coinciding with transient inferior ST elevation and a distinct ‘shark fin’ waveform, indicating dynamic RCA occlusion. The arrhythmias persisted despite initial medical management, including calcium channel blockers and intravenous glyceryl trinitrate. Percutaneous coronary intervention to the moderate RCA lesion was performed, which definitively treated the arrhythmias. This case emphasises the importance of recognising plaque-associated CAS as a potential trigger for life-threatening arrhythmias, even in the absence of chest pain. While medical therapy remains first-line treatment, life-threatening presentations may necessitate invasive interventions to stabilise the patient and prevent recurrence....

Heart failure (HF) is a highly prevalent long-term condition, with variation in services and resources across the UK. This report provides findings from a cross-sectional survey of community HF services in the UK between September 2021 and February 2022. Eighty-five responses describing community HF services were received. Community services were primarily led by a HF specialist nurse (HFSN), with a median of 1.25 cardiology consultants with HF training, and a variety of other nurses and support workers. All services reviewed patients with HF with reduced ejection fraction (HFrEF), only 58% reviewed patients with HF with preserved ejection fraction (HFpEF). Median wait time was 20 days, with substantially longer waits in many areas. All services accepted referrals from multiple sources. Most services provided admission avoidance (96.5%), post-discharge checks (87%), pharmacological optimisation (99%), ongoing monitoring (82%) and palliative care (87%). In conclusion, UK community-based HF teams provide many services, however, there is significant geographical variation. Studies are needed to determine if they are adequately resourced to meet population needs and improve patient outcomes....

Hyperbaric oxygen therapy (HBOT) is successfully implemented for the treatment of several disorders. HBOT is a promising treatment modality for coronary artery disease (CAD), where outcomes are frequently poor despite early revascularisation. The aim of this study is to investigate the effect of HBOT on the left ventricular function of patients with CAD after reperfusion. Electronic journal searching was performed in PubMed, ScienceDirect, and Cochrane to find studies that investigate the effect of HBOT on the myocardial function of patients with CAD. The primary outcomes were left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF). Meta-analyses were performed on included studies and mean differences (MD) and 95% confidence intervals (CI) were estimated using Review Manager v5.4. A total of three observational studies enrolling 195 participants were included in our analysis. HBOT significantly increased LVEF by 4.16% in patients with CAD after revascularisation compared with non-HBOT (MD=4.16, 95%CI 0.97 to 7.34, p=0.01). There was no statistical significance observed in the HBOT versus non-HBOT comparison on LVEDV (MD=–1.63, 95%CI –6.52 to 3.26, p=0.51) and LVESV (MD=–1.58, 95%CI –4.06 to 0.90, p=0.21). In general, this meta-analysis shows HBOT significantly increased LVEF in patients with CAD after revascularisation compared with non-HBOT. There were no significant changes in LVEDV and LVESV in the HBOT group and non-HBOT group....

For more than 30 years, Cardiac Risk in the Young (CRY) has been at the forefront of efforts to prevent sudden cardiac deaths in young people. Established in 1995, CRY has transformed the landscape of cardiac screening, research, and bereavement support in the UK and beyond. Through pioneering research, large-scale screening initiatives, and raising awareness, CRY has saved lives, supported affected families, and driven critical policy changes. This article explores CRY’s impact over the past three decades and its continuing efforts to prevent young sudden cardiac death (YSCD)....
