Presentation of basilar artery stroke secondary to patent foramen ovale: a diagnosis made with a 'selfie'.

We report the case of a woman in her late 20s, with no significant medical history, who was found unresponsive at home. Her mother revealed a 'selfie' sent to her by the patient 30 min prior to collapse which revealed bilateral ptoses. Initial brain imaging with non-contrast CT of the brain revealed nil of note. A multiphase CT angiogram revealed an acute basilar artery thrombosis. She underwent timely thrombolysis and was transferred for endovascular thrombectomy. Further evaluation with an aim to define the aetiology revealed the diagnosis of patent foramen ovale with a resultant paradoxical embolism. The differential diagnoses of unexplained rapidly evolving neurology with reduced Glasgow coma scale, and relevant appropriate investigations are discussed in this case report.

Insulinoma as a cause of seizure-like activity and spontaneous hypoglycaemia.

A woman in her 60s presented to our hospital with recurrent episodes of confusion and double vision with spontaneous recovery to baseline within 10 min. Her initial workup was unremarkable, and she was diagnosed with complex partial seizures and commenced on levetiracetam. The following week, she re-presented with a recurrence of her symptoms, associated with spontaneous hypoglycaemia, with blood glucose levels of 1.9 mmol/L. She was found to have endogenously elevated serum insulin and C peptide levels, which were concomitantly associated with hypoglycaemia. An initial diagnosis of insulinoma was made and she was commenced on diazoxide. MRI and endoscopic ultrasound revealed 16 mm insulinoma in her uncinate process. She underwent surgical resection and remained symptom free at follow-up. This case highlights the importance of blood glucose measurements in patients presenting with neuroglycopenic symptoms and outlines the workup and management of insulinoma.

Post-Coronavirus Disease 2019 (COVID-19) Syndrome Associated with Central Retinal Vein Occlusion: A Case Report.

PURPOSE: Coronavirus Disease 2019 (COVID-19) pneumonia may predispose to thromboembolic disease, including after the acute phase. We report on a unique case of central retinal vein occlusion (CRVO) occurring eight months after diagnosis of Coronavirus Disease 2019 (COVID-19) pneumonia in a likely case of post-COVID-19 syndrome. CASE REPORT: A 42-year-old man developed blurred vision in his right eye eight months after symptoms of pneumonia. He had no underlying medical conditions, but experienced exertional chest pain since diagnosis of COVID-19 was confirmed by detection of SARS-CoV-2 on nasopharyngeal swab and was also seeing cardiology for management of myocarditis. His best-corrected visual acuity on snellen chart testing was reduced to 6/18 in the affected right eye, and dilated fundal examination revealed a non-ischaemic CRVO. CONCLUSION: The thromboembolic complications of COVID-19 may extend to CRVO, which in this case presented months after onset of symptoms of pneumonia, in association with myocarditis.

Review of Irish patients meeting ST elevation criteria during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic has seen the introduction of important public health measures to minimise the spread of the virus. We aim to identify the impact government restrictions and hospital-based infection control procedures on ST elevation myocardial infarction (STEMI) care during the COVID-19 pandemic. METHODS: Patients meeting ST elevation criteria and undergoing primary percutaneous coronary intervention from 27 March 2020, the day initial national lockdown measures were announced in Ireland, were included in the study. Patients presenting after the lockdown period, from 18 May to 31 June 2020, were also examined. Time from symptom onset to first medical contact (FMC), transfer time and time of wire cross was noted. Additionally, patient characteristics, left ventricular ejection fraction, mortality and biochemical parameters were documented. Outcomes and characteristics were compared against a control group of patients meeting ST elevation criteria during the month of January. RESULTS: A total of 42 patients presented with STEMI during the lockdown period. A significant increase in total ischaemic time (TIT) was noted versus controls (8.81 hours (±16.4) vs 2.99 hours (±1.39), p=0.03), with increases driven largely by delays in seeking FMC (7.13 hours (±16.4) vs 1.98 hours (±1.46), p=0.049). TIT remained significantly elevated during the postlockdown period (6.1 hours (±5.3), p=0.05), however, an improvement in patient delays was seen versus the control group (3.99 hours (±4.5), p=0.06). There was no difference seen in transfer times and door to wire cross time during lockdown, however, a significant increase in transfer times was seen postlockdown versus controls (1.81 hours (±1.0) vs 1.1 hours (±0.87), p=0.004). CONCLUSION: A significant increase in TIT was seen during the lockdown period driven mainly by patient factors highlighting the significance of public health messages on public perception. Additionally, a significant delay in transfer times to our centre was seen postlockdown.

Emergency TAVI in cardiogenic shock and cardiorenal syndrome secondary to severe bicuspid aortic stenosis.

A 78-year man with severe aortic stenosis awaiting elective surgical aortic valve replacement presented with worsening New York Heart Association IV shortness of breath. Despite appropriate heart failure treatment, he deteriorated and developed cardiogenic shock and cardiorenal syndrome which progressed despite inotropic support. A non-contrast-gated CT coronary angiogram was arranged in light of acute renal failure which revealed a bicuspid aortic valve. Three-dimensional transoesophageal echocardiography guidance was used to assist annulus sizing. An emergency transcatheter aortic valve replacement (eTAVI) was carried out 5 days into admission with a 34 mm Core Valve Evolut Pro valve with a no contrast technique. The patient's blood pressure and urine output improved and no procedural complications were encountered. He was discharged after 21 days and has remained well subsequently. This case highlights the utility of eTAVI and demonstrates the feasibility of a no contrast approach.
