Scorpion Envenomation

We describe a case of severe scorpion envenomation in an adult patient, with the presence of very rapid sustained ventricular tachycardia followed by cardiogenic shock, which was reversed by scorpion antivenom administration. Scorpion venom causes cardiac changes that can lead to an environment favoring arrhythmogenesis.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiogenic shock (CS) and the presence of sustained ventricular tachycardia (VT) are indicators of worse prognosis in hospitalized patients. In patients severely ill, like patients with CS, the registration of VT can be a stressful situation as well a life threatening condition. Purpose Evaluate the impact of cardiovascular previous history, clinical signs and diagnosis procedures at admission as predictors of VT in CS patients. Methods Single-centre retrospective study, engaging patients hospitalized for CS between 1/01/2014-30/10/2018. 222 patients with CS are included, 19 of them presented VT. Chi-square test, T-student test and Mann-Whitney U test were used to compare categorical and continuous variables. Multiple linear regression analysis was performed to evaluate predictors of new-onset AF in CS patients. Results CS patients without VT and with VT presented similar age, sex, cardiovascular history (namely arterial hypertension, diabetes, dyslipidemia, obesity, smoker status, alcohol intake, previous acute coronary syndrome, history of angina, previous cardiomyopathy), neoplasia history, cardiac arrest during the CS, clinical signs at admission (like heart rate, blood pressure, respiratory rate), blood results (hemoglobin, leucocytes, troponin, creatinine, C-Reactive protein), left ventricular ejection fraction and the culprit lesion. Curiously, history of previous stroke was higher in the group of VT in CS patients with a 6.9% (p = 0.021). Curiously, VT in CS patient had not impact in mortality rates. Multiple logistic regression reveals that previous stroke was a predictor of VT in CS patients (odds ratio 4.337, confident interval 1.363-13.799, p = 0.013). Conclusions History of previous stroke was a predictor of sustained VT in CS patients. The presence of this ventricular arrhythmia can have a hemodynamic impact, however, seems not influenced mortality rates.

Abstract Funding Acknowledgements Type of funding sources: None. OnBehalf Portuguese Registry of Acute Coronary Syndromes Background Atrioventricular block (AVB) can be a consequence of ischemia in acute coronary syndrome (ACS). Then, its expected, that AVB occurrence is associated with higher rates of major adverse cardiac events (MACE). Objective Evaluate if sustained AVB was a predictor of MACE in ACS hospitalized patients. Methods Multicenter retrospective study, based on the Portuguese Registry of ACS between 1/10/2010-3/05/2020. Patients were divided into two groups: A – patients without AVB, and B – patients that presented AVB. Were excluded patients without a previous cardiovascular history or clinical data regarding AVB occurrence. MACE was defined as re-infarction, congestive heart failure, cardiogenic shock, a mechanical complication of myocardial infarction, completed atrioventricular block, sustained ventricular tachycardia, cardiac arrest, stroke, major hemorrhage, transfusion and hospitalization death. Univariate logistic regression was performed to assess if AVB in ACS patients was a predictor of MACE. Results A total of 32157 patients was analyze and 23774 had information regarding AVB. From the group of patients that presented AVB, 214 (0.9%) had re-infarction, 3847 (16.2%) had congestive heart failure, 1018 (4.3%) had cardiogenic shock, 1069 (4.5%) had atrial fibrillation, 152 (0.6%) had a mechanical complication of myocardial infarction, 354 (1.5%) had sustained ventricular tachycardia, 706 (3.0%) had cardiac arrest, 152 (0.6%) had stroke, 364 (1.5%) had major hemorrhage, 353 (1.5%) had blood transfusion and 928 (3.0%) died. AVB did not predict re-infarction (p = 0.145), congestive heart failure (p = 0.334), atrial fibrillation (p = 0.171), mechanical complication of myocardial infarction (p = 0.465) and cardiac arrest (p = 0.142). Logistic regression revealed that AVB in ACS patients was a predictor of cardiogenic shock (odds ratio (OR) 2.350, p = 0.012, confidence interval (CI) 1.207-4.572), sustained ventricular tachycardia (OR 2.269, p = 0.013, CI 1.187-4.340), stroke (OR 2.231, p < 0.001, CI 1.779-5.852), major hemorrhage (OR 3.863, p < 0.001, CI 2.667-5.558), blood transfusion (OR 4.291, p < 0.001, CI 3.002-6.137) and hospitalization death (OR 2.699, p < 0.001, CI 1.725-4.222). Conclusions AVB in ACS patients predict MACE, namely cardiogenic shock, sustained ventricular tachycardia, stroke, major hemorrhage, blood transfusion and hospitalization death.

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses with unknown cause. A 60-year-old man presented with sustained ventricular tachycardia. Transthoracic echocardiography and contrast-enhanced angio-computed tomography demonstrated an expanding 73 × 40 mm sized calcified mass in the left ventricle. He underwent successful total removal of the mass and cryo-ablation at the normal myocardial border. Histopathological examination confirmed a diagnosis of cardiac calcified amorphous tumors. The postoperative course was uneventful, without ventricular tachycardia recurrence. To our knowledge, this is the first reported case of confirmed cardiac calcified amorphous tumors causing ventricular tachycardia and treated by surgical resection combined with cryo-ablation.
