Ruptured abdominal aortic aneurysms are associated with high mortality rates and require prompt diagnosis with subsequent intervention. CT scan is considered the gold-standard for diagnosis, however, in the acute setting ultrasound may be a reasonable diagnostic test for certain patients. We report a case that demonstrates the utility of bedside ultrasound of rAAA for a patient in extremis. Also, we provide a brief review of literature for the diagnosis of rAAA with ultrasound.

Right atrial appendage aneurysms (RAAAs) are extremely rare in cardiac anomaly. According to the literature, no more than 25 cases have been reported so far, among which only 3 cases were children. Here, we reported an infant with a giant RAAA and severe symptoms. The RAAA was diagnosed by echocardiography and surgically resected under cardiopulmonary bypass. The role of transesophageal echocardiography was very important during the aneurysm resection surgery, which helped surgeons to plan surgical procedures during the surgery and evaluate the surgical effect postoperatively.

Massive myocardial calcification is a very rare finding. Accurate identification and characterization may help the clinicians to determine the etiology and clinical significance. In this case, the diagnostic pathway excluded previous myocardial infarction, myocarditis and calcium-phosphate disorders. A possible dystrophic etiology was considered. There are no standardized imaging features available to classify specific subtypes of intramyocardial calcifications. The relative merits of cardiac computed tomography and magnetic resonance in providing complimentary diagnostic information for calcific myocardial lesions is shown. Knowledge of the potential etiology and their imaging patterns are important to provide a concise and accurate differential diagnosis.

Bioprosthetic valve thrombosis is a growing recognized entity, especially with the increasing use of the valve in vale procedures and the advent of new detection technologies (e.g., 4D CT and 4D echocardiography). However, the optimal management strategy in the acute context is not established. This paper presents a case of early thrombosis following the percutaneous tricuspid valve in vale procedure that was successfully managed with thrombolysis.

57-years old man presented with exertional dyspnea. An early systolic murmur was heard over the aortic areas 2D and 3D Echocardiography revealed unicuspid , unicommissural aortic valve (UAV) with a characteristic “teardrop” lateral orifice (Figure A) and moderate valve stenosis (3D planimetered aortic valve area (AVA) is 1.1cm2) (Figure B) Continuous wave Doppler across aortic valve (AV) showed high peak and mean systolic gradients of 85 and 60mmHg respectively.(Figure C). 2D /3D Transesophageal Echocardiography (TOE) revealed a subaortic ridge attached to the posterior annulus (Arrow) (Figure D) Further En-face viewing of the aortic valve from the left ventricular outflow tract (LVOT) perspective showed a shelf-like ridge extending from the commissure to the cusp (Arrow) (Figure E) Zoomed mode of the aortic- LVOT junction confirmed the presence of the subaortic ridge seen attached to the posterior aortic annulus near the commissural opening (Figure F) The patient was referred for surgical consultation .. Unicupid aortic valve (UAV) is a rare congenital anomaly that has.2 subtypes ; unicomissural and acommissural subtypes. Both can present with variable degrees of the aortic stenosis (AS) and/or aortic valve regurgitation (AR).UAV has more early, accelerated and severe valvular degeneration in addition to smaller orifice in comparison with bicuspid and tricuspid aortic valve. Echocardiography is the gold standard for diagnosis and evaluation of the AV morphology and function and the associated disorders such as ventricular septal defect , aortopathy and subaortic obstruction.. Surgical aortic valve replacement (AVR) and repair of the associated anomalies are the most common treatment modality .

Aim: We aimed to examine fetal cardiac output (CO) in patients who recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Materials: This prospective study included 48 pregnant women recovered from SARS-CoV-2 infection and 50 control cases. SARS-CoV-2 infection was diagnosed by polymerase chain reaction (PCR) test in patients. Fetal echocardiographic evaluations were performed at 24-37 weeks of gestation in pregnant women who recovered from the infection and control group. Results: The median value of ultrasound evaluation was 34 (2.6) weeks of gestation in the recovery from the SARS-CoV-2 infection (RSI) group, and 32 (7.6) weeks in the control group (p=0.565). Left cardiac output (LCO) z score was significantly lower in the RSI group than the control group (p=0,041). LCO and combine cardiac output (CCO) z score were significantly lower in the severe disease group than mild, moderate disease groups, and controls (p=0,019 and p=0,013). CCO (mL/min/kg) was decreased in the severe disease group when compared with control and mild disease groups (p=0,044). Fetal distress, preterm delivery rate, and neonatal intensive care unit (NICU) admission were found to be higher in the severe disease group compared to the control group (p=0,010, p=0,009, and p<0,001 respectively). Conclusion: In the present study, fetal cardiac output in pregnant women with recovery from SARS-CoV-2 infection was found significantly decreased, especially in whom had severe diseases. Placental dysfunction and inflammatory cytokines might cause fetal cardiac changes. Further studies could be clarified on the impact of SARS-CoV-2 infection on fetal cardiac function.

Background: Accessory mitral valve tissue (AMVT) is an extremely rare causes left ventricular outflow tract (LVOT) obstruction and is usually incidentally detected in childhood. It is often associated with other cardiac and vascular congenital malformations. Case Presentation: In this case, we present a 15-year-old girl was diagnosed with AMVT by transesophageal echocardiography, resulting in LVOT obstruction during systole. Interestingly enough, the patient’s accessory mitral valve remained undetected for years until he became symptomatic for wide ASD. Successful closure of the ASD with resection of the AMVT was performed with a transaortic approach. The patient was hemodynamically stable postoperatively. There were no abnormalities in the mitral valves and LVOT. Conclusion: It was also unusual to see AMVT with ASD instead of other frequently associated other congenital anomalies. Accessory mitral valve should be considered a rare but important cause of left ventricular outflow tract obstruction in childhood.

Herein we present a case of concomitant congenital anomalies with an iatrogenic defect. The female patient underwent a percutaneous mitral balloon valvuloplasty due to rheumatic mitral stenosis. Unfortunately, an iatrogenic atrial septal defect (ASD) occurred and also, partial anomalous pulmonary venous return was observed at post-procedure evaluation. The patient had severe symptoms and the right heart chambers were dilated on imaging. But perhaps, the most crucial point was that the patient was planning a pregnancy. After a difficult and patient-involved decision process, the patient underwent to successful robotic surgery for iatrogenic ASD and partial anomalous pulmonary venous return. After operation, the patient was asymptomatic and right heart chambers normalized.

COVID-19 related MIS-C (Multisystem inflammatory syndrome in children) can present with cardiovascular complications like shock, arrhythmias, pericardial effusion, and coronary artery dilatation. The majority of MIS-C associated coronary artery abnormalities are dilation or small aneurysms which are transient and resolve in a few weeks[[1, 2]](#ref-0001). We present here a case of a 3-month-old child who was noted to have giant aneurysms of her coronary arteries (LAD and RCA) twenty-six days after testing positive for COVID-19. She was treated with IVIG, infliximab, and glucocorticoids along with aspirin, clopidogrel and enoxaparin. She did not show any signs of coronary ischemia or cardiac dysfunction but continued to have persistent giant coronary artery aneurysms involving the LAD (z-score ~35) and RCA (z-score ~30) [Fig. 1]. This study emphasizes the importance of early detection and aggressive management of MIS-C to prevent potentially life-threatening consequences.

Objective: To study the value of fetal epicardial fat thickness (EFT) in gestational diabetes mellitus in the third trimester of pregnancy and its relationship with clinical parameters and perinatal outcomes. Methods: A total of 80 participants, including 40 with diagnosed GDM and 40 healthy pregnant women, were included in the study. Demographic data were obtained from medical records. Sonographic examinations were performed, such as amniotic fluid value, fetal biometric measurements, and Doppler parameters of the umbilical artery. Fetal EFT values were measured at the free wall of the right ventricle using a reference line with echocardiographic methods. Correlation tests were performed to evaluate the relationship between fetal EFT and clinical and perinatal parameters. P < 0.05 were interpreted as statistically significant. Results: The fetal EFT value was statistically higher in the GDM group than in the control group (p:0.000). Spearman correlation tests revealed statistically significant but weak positive correlations between fetal EFT value, 1-hour 100-gr OGTT, birth weight, and BMI (r: 0.198, p:0.047; r:0.395, p:0.012; r:0.360, p:0.042, respectively). The optimal fetal EFT threshold for predicting GDM disease was found as 1.55 mm, with a specificity of 74.4% and sensitivity of 75.0%. Statistically significant differences between the two groups in umbilical artery Doppler resistance index (RI), pulsatility index (PI), and systolic/diastolic ratio (S/D) were not found (p:0.337; p:0.503; p:0.155;). BMI and amniotic fluid volume were higher in the GDM group compared to the control group (p:0.009; p:0.000). Conclusion: This study demonstrated that increased fetal EFT may occur as a reflection of changes in glucose metabolism in intrauterine life. Future studies with larger series, including the study of neonatal metabolic parameters, will contribute to the understanding of the importance of fetal EFT in determining the metabolic status of the fetus.

Objectives In stress echocardiography (SE), dipyridamole (DIP) and dynamic stress (ExSE) are reported as safer than dobutamine stress (DSE). We investigated whether commonly used stressors cause myocardial injury, measured by high sensitivity troponin T (hsTnT). Methods 135 patients (DSE n=46, ExsE n=46, DIP n=43) with negative SE were studied. Exclusion criteria were known ischemic heart disease (IHD), baseline wall motion abnormalities, left ventricle systolic dysfunction/regional wall motion abnormalities, septum/posterior wall ≥13 mm, diabetes, baseline hsTnT level ≥14 ng/L, baseline blood pressure ≥160/100 mmHg, peak pulmonary pressure ≥45mmHg, eGFR <1mL/s/1.73m2, more than mild to moderate valvular disease and dobutamine side effects. HsTnT was measured before and 180 minutes after the test. Results All patients had low pre-test probability of IHD. HsTnT increased in DSE, less so in ExSE, and unchanged in DIP group [9.4 (1.5–58.6), 1.1 (-0.9–15.7), -0.1 (-1.4–2.1) ng/L, p<0.001]. In DSE, hsTnT change was associated with peak dobutamine dose (r=0.30, p= 0.045), test length (r=0.43, p=0.003) and atropine use (p<0001). In ExSE, hsTnT rise was more likely in females (p=0.012) and elderly (>65 years) (r=0.32, p=0.03), no association was found between atropine use (p=0.786) or test length and hsTnT rise (r=0.10, p=0.530). Conclusions DSE is associated with myocardial injury in patients with negative SE, no injury was observed in DIP and only mild one in ExSE. Whether myocardial injury is causative of the higher reported adverse event rates in DSE remains to be determined.

Prosthetic valve endocarditis with mechanical complications causing pulmonary edema is fatal, therefore it needs to be diagnosed early and should be treated surgically in emergency setting. Transesophageal echocardiogram is crucial for recognizing the mechanical complications, which can be encountered on daily practice, but the coexistence of complications occurring on different mechanism is rather uncommon. Herein, we report a 21-year-old gentleman presenting with acute heart failure, whose imaging tests showed a combination of dehiscence of mechanical aortic valve prosthesis, aortic dissection, pseudoaneurysm and hematoma causing right ventricular collapse.

Objectives: Echocardiographic assessment of Left ventricular systolic function is traditionally being performed by estimation of fractional shortening and Ejection fraction. Speckle tracking echocardiography (STE) is a promising tool for assessment of myocardial function. The aim of this study is to evaluate the global longitudinal strain (GLS) using 2D-STE in healthy neonates to establish normal reference ranges. Method: it is a retrospective study through an analysis of transthoracic echocardiogram of normal healthy neonates. We enrolled all neonates in our institution from 1 st January 2021 to 28 th February 2021. 2-D STE was used to assess left ventricular global longitudinal strain from the apical views. Results: 185 neonates were enrolled. Mean value for left ventricle GLS (%) was -19.9 ± 1.2, GLS-derived ejection fraction (%) was 60.0 ± 2.7; while the left ventricle ejection fraction by biplane Simpson’s method (%) was 61.0 ± 3. There is a good positive correlation between the Left Ventricle EF by biplane Simpson’s method and EF by 2-D STE, which was statistically significant ( r = 0.294,  n = 102,  p=0.003). Apical 4-chamber longitudinal strain and strain derived EF is significantly correlated with GLS and bi-plan EF respectively. Conclusion: 2-STE is feasible technique for analyzing newborn myocardial systolic function. The normal range of GLS in neonates is not much different than reported for the pediatric. There is a good positive correlation between the Left Ventricle EF by 2-D STE and EF by biplane method.

Background: Three-dimensional echocardiography (3DE) is an emerging method for volumetric cardiac measurements; however, few vendor-neutral analysis packages exist. Ventripoint Medical System Plus (VMS3.0+) proprietary software utilizes a validated MRI database of normal ventricular and atrial morphologies to calculate chamber volumes. This study aimed to compare left ventricular (LV) and atrial (LA) volumes obtained using VMS3.0+ to Tomtec echocardiography analysis software. Methods: Healthy controls (n=98) aged 0 to 18 years were prospectively recruited and 3D DICOM datasets focused on the LV and LA acquired. LV and LA volumes and ejection fractions were measured using TomTec Image Arena 3D LV analysis package and using VMS3.0+. Pearson correlation coefficients, Bland-Altman’s plots and intraclass coefficients (ICC) were calculated, along with analysis time. Results: There was a very good correlation between VMS and Tomtec LV systolic (r 2 = 0.88, ICC 0.89 [95% CI 0.81,0.94]), and diastolic (r 2 = 0.88, ICC 0.90 [95% CI 0.77,0.95]) volumes, and between VMS and Tomtec LA diastolic (r 2 =0.75, ICC 0.89 [95% CI 0.81,0.93]) and systolic (r 2 =0.88, ICC 0.91 [95% CI 0.78,0.96]) volumes on linear regression models. Natural log transformations eliminated heteroscedasticity, and power transformations provided best fit. The time (mins) to analyze volumes using VMS were less than using Tomtec (LV VMS 2.3±0.5, Tomtec 3.3±0.8, p<0.001; LA: VMS 1.9±0.4, Tomtec 3.4±1.0, p<0.001). Conclusions: There was very good correlation between knowledge-based (VMS3.0+) and 3D (Tomtec) algorithms when measuring 3D echocardiography derived LA and LV volumes in pediatric patients. VMS was slightly faster than Tomtec in analyzing volumetric measurements.

Background: Tako-tsubo syndrome (TTS) in its most typical form shares common features with anterior ST segment elevation myocardial infarction (AMI) during acute presentation. Differential diagnosis between the two conditions is often challenging especially if ST segment elevation is associated with extensive apical akinesis. Methods: we sought to systematically analyze ECG and echocardiographic parameters including LV longitudinal strain and two new indexes: the inferior-apex ratio (IAR) and the inferior-lateral-apex ratio (ILAR), to assess if ventricular involvement may be different in TTS and AMI. Results: A retrospective cohort study was conducted with 2 groups: patients with TTS (n=22) and patients with extensive anterior STEMI (n=22). Lack of ST elevation in V1 was associated with TTS with sensitivity and specificity of 86%, positive and negative predictive value of 86%. Longitudinal strain in mid inferior and mid inferior-lateral segments were more compromised in TTS: - 4.3±6.4% and -5.4± 5.4% in TTS vs -10.2±5.5% and -9.9 ±4.9% in AMI, respectively (P<0.01 for all). By multivariate analysis, both longitudinal strain values, inferior-apical ratio (IAR) <1 and inferior-lateral-apical ratio (ILAR) <1 were independently associated with diagnosis of TTS during acute phase. Conclusions: our results suggest that impaired contractility extending beyond apex to mid inferior and inferior-lateral walls can be easily assessed by IAR and ILAR, and these indexes facilitate non-invasive differentiation of TTS from extensive anterior STEMI.

Background Right ventricular dysfunction is a major cause of heart failure and mortality in end-stage renal disease patients. Scarce data is available regarding the comparison of echocardiographic right ventricular function in end-stage renal disease patients on hemodialysis (HD) and peritoneal dialysis (PD). The aim of the study was to evaluate the long-term impacts of different dialysis modalities on right ventricular function assessed by conventional echocardiography, in end-stage renal disease patients with preserved left ventricular function. Methods The study included 120 patients grouped as follows: PD(n=40), HD with arterio-venous fistula (n=40) and healthy control subjects (n=40). Conventional echocardiography was performed in all patients. A classification of right ventricular function was defined in HD patients by using tricuspid annular plane systolic excursion (TAPSE), right ventricular myocardial performance index (RV-MPI), fractional area change (FAC) and tricuspid lateral annulus systolic velocity (Sa) values. Correlation analysis was performed by using right ventricular dysfunction score, clinical and echocardiographic parameters. Results The mean age of the study population was 51.9±13.1 years and 47.5% were females. TAPSE and Sa velocity were found to be significantly lower and RV-MPI was significantly higher in patients undergoing HD, compared with control and PD patients. Logistic regression analysis showed that HD treatment was an independent risk factor for developing right ventricular dysfunction. Conclusion RV function was impaired in patients undergoing HD compared with patients on PD.

Purpose: Left ventricular diastolic dysfunction (LVDD) is associated with poor outcomes in intensive care unit (ICU). Nonetheless, precise reporting of LVDD in COVID-19 patients is currently lacking and assessment could be challenging. Methods: We performed an echocardiography study in COVID-19 patients admitted to ICU with the aim to describe the feasibility of full or simplified LVDD assessment and its incidence. We also evaluated the association of LVDD or of single echocardiographic parameters with hospital mortality. Results: Between 06.10.2020 and 18.02.2021, full diastolic assessment was feasible in 74% (n=26/35) of patients receiving full echocardiogram study. LVDD incidence was 46% (n=12/26), whilst the assessment produced different results (incidence 81%, n=21/26). Nine patients were hospital-survivors (39%); incidence of LVDD (full assessment) was not different between survivors (n=2/9, 22%) and non-survivors (n=10/17, 59%; p=0.11). Also, the E/e’ ratio lateral was lower in survivors (7.4 [3.6] vs non-survivors 10.5 [6.3], p=0.03). We also found that s’ wave was higher in survivors (average, p=0.01). Conclusion: In a small single-center study, assessment of LVDD according to latest guidelines was feasible in three quarter of COVID-19 patients. Non-survivors showed a trend towards greater LVDD incidence; moreover, they had significantly worse s’ values (all) and higher E/e’ ratio (lateral).
