Introduction: Lipid emulsions are increasingly used as an antidote to lipophilic drug intoxications. The dose recommended by the American Society of Regional Anesthesia is used primarily for the treatment of local anesthetic systemic toxicity. There is insufficient information about what the dose of lipid emulsions (LE) should be in other intoxications depending on their severity. Aim: To determine the LE dose in a shock or haemodynamic instability in patients with acute exogenous intoxications treated with LE. Materials and methods: Forty-nine patients with acute lipophilic drug intoxications were treated with LE in the Clinic of Toxicology at the Naval Hospital in Varna. Statistical analysis was performed using the statistical functions of Excel 2016 and the Statistica 7.0 software package. Results: The percentage of patients receiving a low dose of LE of 0.3 ml/kg (93.87%) was significantly higher than the percentage of patients treated with a medium (2.04%) and a high dose (4.08%) of LF. The high dose of LE of 1.5 ml/kg recommended by the American Society of Regional Anesthesia was administered to two patients (4.08%). In severe intoxications with exotoxic shock, the rate of LE administration varies from 20 ml/h to 40 ml/h. Conclusions: In severe intoxications with cardiotoxic syndrome and haemodynamic instability, LE should be used in the dose as suggested by the American Society of Regional Anesthesia. It is possible to use lower doses of LE in the range of 0.3–0.6 ml/kg in all moderate poisonings administered by continuous intravenous infusion for 12-24-48 hours. No side effects were observed at these doses.

Cytokine storm syndrome (CSS) is a critical condition induced by a cascade of cytokine activation, characterized by overwhelming systemic inflammation, hyperferritinaemia, haemodynamic instability and multiple organ failure. At the end of 2019, the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China, and rapidly developed into a global pandemic. There is a dramatic increase of inflammatory cytokines in patients with COVID-19, suggesting the existence of cytokine storm in some critical illness patients. Here, we summarize the p

Abstract Background Thoracic epidural analgesia (TEA) has been the traditional option for post-operative pain management for Kausch-Whipple pancreaticoduodenectomy (KWPD) via a ‘reverse L’ incision. An alternative option with inter-pleural analgesia (IPA) has become popular. However, the superior form of analgesia for KWPD regarding analgesic and non-analgesic outcomes is unclear. This study aims to establish if IPA is equivalent to TEA. Methods Retrospective study of all patients who underwent KWPD with ‘reverse L’ incision by a single surgeon between February 2014 to June 2016. All received either IPA or TEA post-operatively; patients who had rectus sheath catheter and spinal anaesthesia were excluded. To reduce bias, the Anaesthetist, rather than Surgeon, decided the choice of analgesia based on personal skill. Efficacy regarding analgesia were collected by nursing staff as patient-reported pain severity (mild, moderate or severe). Data were collected from patient case notes and electronic records. This study analysed analgesia efficacy, complications, inotrope use, and intensive treatment unit (ITU) stay. Results A total of 40 included in the study. Twenty-two patients had TEA (45% female, median age 68 years) and 18 had IPA (44% female, median age 67 years). Median Charleson Comorbidity Index (CCI) was 5 for both. Patient-reported pain was not statistically different (p = 0.15). We noted more analgesia complications with TEA (not working=4, leakage=2, haemodynamic instability=1, lower limb anaesthesia=1) than IPA (leakage=1; p = 0.027). Eleven (50%) TEA and eight (44%) IPA patients required inotropes. TEA patients required significantly longer duration (median duration 35 VS 18 hours, p = 0.047). Median ITU stay was 3 and 2 days for TEA and IPA patients, respectively. Conclusions Both TEA and IPA provide adequate pain relief for KWPD performed via a ‘reversed L’ incision. However, evidence suggests TEA was associated with significantly more analgesia-related complications and longer inotropic requirements. Furthermore, there was also a trend towards ITU stays with TEA. Therefore, we would recommend the use of inter-pleural analgesia over thoracic epidural.

Abstract Aims We know that basal septal hypertrophy is a rare and unique anatomical finding associated with hypertrophic cardiomyopathy (HCM). Tako-Tsubo cardiomyopathy (TTC) is a transient left ventricular systolic dysfunction induced by high physical or emotional stress. Its occurrence with HCM is unusual. However, this presentation occurs more often with the classic asymmetrical septal hypertrophy compared with the apical variant. This case demonstrates that the coexistence of TTC with septal HCM in an elderly patient may lead to a severe haemodynamic instability picture. Methods and results A 81-year-old female presented to the emergency department (ED) complaining of dyspnoea and chest pain lasting for 1 day. She had hypertension and dyslipidemia associated with a familial history of sudden death. On physical exam, we found a severe hypotension (systolic blood pressure of 80 mmHg) associated with bilateral rales at chest auscultation. Cardiac auscultation revealed a harsh systolic murmur, best heard over the left sternal border. Heart rate was 60 b.p.m. in sinus rhythm. Labs were significant for HS-I troponin of 6.035 ng/L (NV: ≤ 12) and NT-proBNP of 7.640 pg/ml (NV: ≤1800). A 12-leads electrocardiogram (ECG) at admission revealed a STEMI-like ST segment elevation from V2 to V6 (Figure 1A). For this reason she was urgently taken to the cath-lab where she was found to have tortuous but normal coronary arteries. After coronary angiography, a trans-thoracic echocardiogram (TTE) revealed a pathological LV hypertrophy with a septal diastolic thickness of 19 mm, depressed LV ejection fraction (LVEF) due to a severe apical ballooning. At continuous wave (CW)-Doppler there was a dynamic obstruction across the LV outflow tract (LVOT), with a late peak velocity of 4.9 m/s and an estimated peak gradient of 98 mmHg. The gradient was increased by a systolic anterior motion (SAM) of anterior mitral leaflet causing a moderate mitral regurgitation (MR). All these findings were consistent with obstructive septal HCM associated with Takotsubo cardiomyopathy. After treatment with intravenous diuretics and metoprolol (5 + 5 mg i.v. bolus followed by oral dose of 100 mg daily), her clinical condition markedly improved. One week later, ECG demonstrated deeply inverted T waves on antero-lateral leads and QT prolongation (501 ms). Three weeks later, after a complete resolution of the LV apical dyskinesia, LVEF normalized. LVOT gradient decreased to 20 mmHg, with a dynamic increase to 70 mmHg during Valsalva manoeuvre. Conclusions It is well known that TTC may be complicated by a reversible LVOT obstruction by itself but the combination with obstructive HCM can lead to low cardiac output and acute heart failure. This combination has been found to be not common and the correct treatment of this unusual type of cardiogenic shock is still unclear. Careful initial evaluation and continuous monitoring must be warranted in such rare cases. Supportive care afterward with beta blockers, along with echocardiogram surveillance, are the mainstay of management. Cardiologists, intensivisits, and clinicians alike need to recognize and comprehend the pathophysiology behind this unique clinical manifestation so that they may adjust their management and treatment accordingly.

Abstract Aims Left atrial appendage aneurysm (LAAA) is a rare condition mostly due to congenital malformations or secondary causes. Methods and results Since very few cases are described in the literature, there is uncertainty in treatment and prognosis. Diagnosis is achieved by advanced imaging as transesophageal echocardiography (TEE), which also allows the detection of thrombus, moreover cardiac magnetic resonance (CMR) could be more specific in describing sizes and relationships with surrounding anatomical structures. Surgical aneurysmectomy could be indicated in the majority of cases, especially if compression of other cardiac chambers or mediastinal structures are present. Medical therapy can include tromboprophylaxys and arrhythmias management. Since high quality evidence is scarce, a shared decision making by Heart Team approach should be considered. We present the case of a 47 years old male who came to our attention for palpitations and epigastric pain. The ECG showed high ventricular rate atrial fibrillation (AF) with wide QRS (left bundle branch block morphology). Due to haemodynamic instability the patient underwent urgent electrical cardioversion and coronary angiography showed patent coronary arteries. He had a giant left auricle appendage diagnosed twelve years before and was on antiarrhythmic prophylaxis for previous AF episodes. A TEE was performed and confirmed the diagnosis of LAAA also showing hypokinetic anterior-apical wall due to the interplay with the giant aneurysm. Subsequent CMR showed no LGE and confirmed the absence of thrombus in the LAAA. After Heart Team consultation surgical treatment was proposed to the patient who refused any invasive procedure. Therefore medical treatment was achieved by direct oral anticoagulation and antiarrhythmic therapy with betablockers and flecainide per os. Moreover, a loop recorder for longitudinal monitoring was implanted. At 6 months of follow-up the patient was asymptomatic except for a brief paroxysm of self-limited AF. 510 Figure 1CMR scan showing giant left atrial appendage aneurysm. (A) Transversal view.

Abstract Aims The inflammatory ‘cytokine storm’ that distinguishes COVID-19 pneumonia is associated with a state of systemic hypercoagulability, which leads to thrombotic complications on the venous, arterial, and microvascular side. Indeed, in patients with COVID-19, systemic inflammation, coagulation activation, hypoxemia, and immobilization expose a high risk of pulmonary embolism, which significantly worsens the prognosis of these patients. Methods and results In this report, we discuss the case of a 71-year-old female, with no prior medical history, admitted to the emergency department for syncope, dyspnoea, and fever started 48 h earlier. At presentation, ear temperature was 37 °C, oxygen saturation was 96% on oxygen therapy (6 l/min), the patient appeared hypertensive (160/80 mmHg) and tachycardic (114 b.p.m.). Laboratory tests revealed normal white blood cells count (10 000/μl) and increased C reactive protein (5.60 mg/dl), troponin I (0.417 ng/ml), and d-dimer levels (15743 ng/ml). Electrocardiogram showed sinus tachycardia at HR of 120/min, normal atrioventricular conduction time, new onset right bundle branch block, and inverted T waves on DIII. Considering the symptoms, CTPA was performed, revealing massive acute bilateral pulmonary embolism with peripheral ground glass opacities. Those findings were suggestive of COVID-19 pneumonia. Indeed, the patient was positive for SARS-CoV-2 infection, and a diagnosis of COVID-19 pneumonia complicated by pulmonary embolism was made. Treatments included oxygen, subcutaneous low molecular weight heparin (LWMH), and corticosteroids have been administrated according to current international guidelines. Since no haemodynamic instability was observed during hospitalization the patient was discharged on Warfarin therapy for 6 months. Conclusions In COVID-19 patients treated in a hospital the incidence of pulmonary embolism (PE) is very high. Patients with COVID-19 infection have respiratory symptoms, which often may not be distinguishable from pulmonary embolism symptoms. So, unexpected respiratory worsening, signs of right ventricular dysfunction on transthoracic echocardiogram, and ECG changes should lead to suspicion of the co-presence of pulmonary embolism. This case report shows how COVID-19 infection can be strongly associated with thrombotic complications. For this reason, the guidelines recommend anticoagulation at standard prophylactic doses in all patients admitted with COVID-19 infection.

Abstract An 89-years-old woman presented at Emergency Department with a 10-h history of vertigo, headache, nausea, fatigue, and general discomfort. No chest pain or shortness of breath were reported. She had a history of hypertension, chronic kidney disease, paroxysmal atrial fibrillation (AF), osteoporosis, and hypoacusia. The patient suffered of chronic anxiety and the caregiver referred for a recent and acute emotional distress. At the admission, the patient didn’t show clinical signs of peripheral hypoperfusion. Fine crackles at lungs bases were objectivable with coherent ultra-sound lung comets and mild bilateral pleural effusion. Her usual therapy included nebivolol, apixaban, torsemide, candesartan, and D-vitamin. The EKG showed AF with a heart rate of about 110 b.p.m., no ST-segment deviation and normal QTc. The echo findings showed a slight increase in left ventricle volume with a severe reduction of the ejection fraction due to the akinesia of all apical segments with the typical aspect of the ‘apical ballooning’ and concomitant hyperkinesia of the basal segments. Despite normal dimensions, also the right ventricle showed a peculiar contractile pattern, with hyperkinetic basal movement and akinesia of the apex with the hinge point located in the free wall portion in continuity with the LV septal wall. No significant valvular disease was documented except for moderate tricuspid regurgitation. High-sensitive I troponin peaked up to 1500 pg/ml. The clinical appearance was very suggestive of TTS but INTERTAK score of 61 was not diagnostic and, according to the most recent consensus document, a coronary angiography was performed, without documentation of coronary artery disease. During the hospitalization serial electrocardiographic monitoring showed significant and transient QTc prolongation and dynamic T wave changes resulting in progressive INTERTAK score increase. No ventricular arrhythmic events occurred. The patient was treated with careful fluid support and with beta-blockers for AF rate control. Multiple echocardiographic evaluations documented a progressive recovery of systolic function up to complete normalization of biventricular global and regional systolic function. Clinical data, instrumental evidences and dynamic evolution oriented the diagnosis towards TTS with unusual and uneven impairment of right and left ventricular function. The described case focuses the attention on the reverse McConnell’s sign, an echocardiographic finding not often described in the literature, consisting of akinetic right ventricle apical segment and hyperkinetic basal and mid free wall. This discordant motion is exactly opposite to the classic echocardiographic RV aspect detected in acute significative pulmonary embolism described as McConnell’s sign, hence the name. It has been suggested that this functional variation might be a self-protection system of the heart through a mechanism of hibernation that is similar to that occurring during chronic hypoxia, consisting in a decrease in the ATP utilization and O2 consumption, as suggested by the activation of intracellular β2-induced signalling patterns documented in TTS. Recognizing this finding it’s important not only because it has been associated with a higher risk of developing haemodynamic instability but also to orient working diagnosis of TTS when initial clinical assessment through the INTERTAK score is inconclusive.

Abstract Aims Prognostic stratification of acute myocarditis (AM) presenting with normal left ventricular (LV) ejection fraction (EF) relies mostly on late gadolinium enhancement (LGE) at cardiac magnetic resonance (CMR) imaging. In this specific AM population, LV peak global longitudinal strain (LV-GLS) measured by feature tracking (FT) analysis might provide further prognostic information. Methods and results Data of patients undergoing CMR for clinically suspected AM in seven European Centres, between January 2013 and August 2020, were retrospectively analysed. Those patients fulfilling CMR Lake Louise Criteria (LLC) for the diagnosis of AM and presenting with normal LVEF (≥50%) were included. Patients presenting with heart failure (HF) or significant arrhythmic events, LVEF <50% or haemodynamic instability were excluded. CMR-LGE extent (localized vs. diffuse), localization (subepicardial vs. mid-wall), and distribution (anteroseptal vs. inferolateral) were visually assessed. LV-GLS was measured by dedicated software. The primary outcome was the first occurrence of an adverse cardiovascular event (ACE) including a composite of cardiac death, development of heart failure, life-threatening arrhythmias, or development of LVEF <50%. In patients experiencing more than one event, the first one was considered for the outcome analysis. Of 389 patients with clinically suspected AM, 256 (66%) had confirmed AM with LVEF ≥50% and were included. Median age was 36 years, 71% were males, median LVEF was 60%, and median LV-GLS −17.3%. CMR was performed at a median time of 4 (IQR: 2–12) days from hospital admission. At a median follow-up of 27 months, 24 (9%) patients experienced at least one ACE with development of LVEF <50% accounting for 17 [71%]. Compared to the others, patients experiencing ACEs had lower median LV-GLS values at baseline (−13.9% vs. −17.5%, P = 0.001). At Kaplan–Meier analysis, impaired LV-GLS (both considered as >-20% or quartiles), diffuse and mid-wall LGE were associated with a significantly higher rate of ACEs. LV-GLS remained independently associated with ACEs after adjustment for diffuse or mid-wall LGE as covariate at bivariable analysis. Conclusions In AM with LVEF ≥50%, LV-GLS provides independent prognostic value over LGE, improving risk stratification and providing a rationale for further studies of therapy in this cohort. 100 Figure

Abstract Aims Most patients who had COVID-19 are still symptomatic after many months post infection, but the long-term outcomes are not yet well-defined. The aim of our prospective/retrospective study was to define the cardiac sequelae of COVID-19 infection. Methods and results This monocentric cohort study included 160 consecutive patients (64 females, 60 + 12 years) who had been discharged from the ward or from the outpatient clinic after a diagnosis of COVID-19 and subsequently referred for a follow-up visit. Clinical features as well as lab and instrumental data about the acute phase of the disease, such as haemodynamic instability (HI), cardiac biomarkers, d-dimer, C-reactive protein (CRP), high resolution CT (HRCT) score along with information about the follow-up visit, including ECG and Conventional and Doppler Tissue Echocardiographic (DTE) parameters, were recorded. The median follow-up time after symptom onset was 5 months. At follow-up visit, the majority of the patients reported dyspnoea and asthenia. Moreover, echocardiography showed morpho-functional changes of both right (RV) and left (LV) ventricles, such as RV dilation, increased pressure in the pulmonary circulation, and by-ventricular systolic–diastolic dysfunction. When examined using multivariate analysis, independent of age, sex, and co-morbidities, RV and LV changes were significantly associated (P < 0.05) with HRCT score and HI and with CRP, respectively. Conclusions Our results suggest that COVID-19 may impact RV and LV differently. Notably, the extent of the pneumonia and HI may affect RV, whereas the inflammatory status may influence LV. A long-term follow-up is warranted to refine and customize the most appropriate therapeutic strategies.
