Left ventricular pseudoaneurysm in Lemierre's syndrome: a case report.

Background: Lemierre's syndrome is an infectious phenomenon characterized by oropharyngeal infection with bacteraemia, thrombophlebitis, and distant septic emboli. Septic emboli are a recognized cause of a Type 2 myocardial infarction, with a left ventricular pseudoaneurysm being a rare but important complication of this. Case summary: A 19-year-old male presented with acute confusion, fevers, and a cough. Blood cultures were positive for Fusobacterium necrophorum and initial imaging showed a cavitating pneumonia. Further evaluation revealed septic emboli in the distal digits and brain. The patient initially responded to antibiotic therapy but developed chest pain with increased troponin levels. An electrocardiogram showed inferolateral ST elevation. A transthoracic echocardiogram (TTE) showed hypokinaesia of the mid to apical lateral wall, and a computed tomography (CT) scan showed a pericardial effusion with a possible purulent effusion or abscess. The patient underwent surgical drainage of a sterile effusion. A post-operative TTE and CT demonstrated a left ventricular pseudoaneurysm that was surgically repaired. The venous thrombus was encountered intra-operatively confirming a diagnosis of Lemierre's syndrome. The patient completed the regimen of antibiotics and showed a good post-operative recovery. Discussion: This is the first case described of left ventricular pseudoaneurysm as a complication of Lemierre's syndrome. It highlights not only the importance of serial, multimodality imaging in both diagnostic workup and identification of complications, but also the importance of a multidisciplinary team in the management of patients with complex and rare presentations.

Prospective multicentre cohort study of transthoracic echocardiography provision in the South West of the UK during the first wave of SARS-CoV-2 pandemic.

AIMS: It was predicted internationally that transthoracic echocardiography (TTE) would be vital during the SARS-CoV-2 outbreak. We therefore, designed a study to report the demand for TTE in two large District General Hospitals during the rise in the first wave of the SARS-CoV-2 pandemic in the UK. A primary clinical outcome of 30-day mortality was also assessed. METHODS: The TTE service across two hospitals was reconfigured to maximise access to inpatient scanning. All TTEs of suspected or confirmed SARS-CoV-2 patients over a 3-week period were included in the study. All patients were followed up until at least day 30 after their scan at which point the primary clinical outcome of mortality was recorded. Comparative analysis based on mortality was conducted for all TTE results, biochemical markers and demographics. RESULTS: 27 patients with confirmed SARS-CoV-2 had a TTE within the inclusion window. Mortality comparative analysis showed the deceased group were significantly older (mean 68.4, SD 11.9 vs 60.5, SD 13.0, p=0.03) and more commonly reported fatigue in their presenting symptoms (29.6% vs 71.4%, p=0.01). No other differences were identified in the demographic or biochemical data. Left ventricular systolic dysfunction was noted in 7.4% of patients and right ventricular impairment or dilation was seen in 18.5% patients. TTE results were not significantly different in mortality comparative analysis. CONCLUSION: This study demonstrates an achievable approach to TTE services when under increased pressure. Data analysis supports the limited available data suggesting right ventricular abnormalities are the most commonly identified echocardiographic change in SARS-CoV-2 patients. No association can be demonstrated between mortality and TTE results.

Safety and Cost-Effectiveness of Same-Day Cardiac Resynchronization Therapy and Implantable Cardioverter Defibrillator Implantation.

Cardiac resynchronization therapy (CRT) and implantable cardioverter defibrillator (ICD) implantation improve morbidity and mortality in selected patients. Many centers still admit patients overnight. We evaluated the safety, feasibility, and cost savings of same-day CRT/ICD device implantation by performing a retrospective study of all consecutive elective CRT/ICD implants at a tertiary center from January 2009 to April 2013. All emergency and/or inpatient cases were excluded. Data were collected on baseline demographics, implantation indication, procedure details, complications (categorized as immediate [≤24 hours], short term [24 hours to 6 weeks], medium term [6 weeks to 4 months], and long term [>4 months]), and mortality (30 day and 1 year). Comparisons were made between those having planned same-day versus overnight stay procedures. A cost analysis was performed to evaluate cost savings of the same-day policy. A total of 491 devices were implanted during this period: 267 were elective (54 planned overnight, 213 planned same-day) of which 229 were CRT pacemakers or CRT defibrillators and 38 ICDs. There were 26 total overall complications (9.7%) with no significant differences between planned same-day versus planned overnight stay cohorts (9.4% vs 11.1%, p = 0.8) and specifically no differences in immediate, short-, medium-, and long-term complications at follow-up. The 30-day and 1-year mortality rates did not differ between the two groups. An overnight stay at our hospital costs $450 (£300); our cost saving during this period was $91,800 (£61,200). Same-day CRT/ICD implantation is safe, feasible, and associated with significant cost savings. It provides significant advantages for patients and health care providers, especially given the current financial climate.

Secondary aorto-enteric fistula: a case report and review of literature.

Aorto-enteric fistula (AEF) is an uncommon but potentially fatal condition that is important to identify early because early diagnosis and aggressive management can reduce mortality. We report the case of a 73-year-old man with a history of aorto-bifemoral bypass grafting who was admitted for investigation of tiredness and lethargy. He passed melaena on the day of admission with an associated drop in haemoglobin. Initial upper gastrointestinal endoscopy revealed no significant abnormality. Later in the admission he again passed melaena, this time in large amounts. A repeat endoscopy identified a defect in the duodenal mucosa with visible Dacron graft. The patient went on to suffer another large bleed from which he could not be resuscitated. Our report highlights a fatal manifestation of aorto-enteric fistula, and reviews the associated literature.
