Introduction: Intra-arrest transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) have been introduced in adult patients with cardiac arrest (CA). Whether the diagnostic performance of TTE or TEE is superior during resuscitation is unclear. We conducted a systematic review following PRISMA guidelines.Methods: We searched databases from PubMed, Embase, and Google Scholar and evaluated articles with intra-arrest TTE and TEE in adult patients with non-traumatic CA. Two authors independently screened and selected articles for inclusion; they then dual-extracted study characteristics and target conditions (pericardial effusion, aortic dissection, pulmonary embolism, myocardial infarction, hypovolemia, left ventricular dysfunction, and sonographic cardiac activity). We performed quality assessment using the Quality Assessment of Diagnostic Accuracy Studies Version 2 criteria.Results: A total of 27 studies were included: 14 studies with 2,145 patients assessed TTE; and 16 with 556 patients assessed TEE. A high risk of bias or applicability concerns in at least one domain was present in 20 studies (74%). Both TTE and TEE found positive findings in nearly one-half of the patients. The etiology of CA was identified in 13% (271/2,145), and intervention was performed in 38% (102/271) of patients in the TTE group. In patients who received TEE, the etiology was identified in 43% (239/556), and intervention was performed in 28% (68/239). In the TEE group, a higher incidence regarding the etiology of CA was observed, particularly for those with aortic dissection. However, the outcome of those with aortic dissection in the TEE group was poor.Conclusion: While TEE could identify more causes of CA than TTE, sonographic cardiac activity was reported much more in the TTE group. The impact of TTE and TEE on the return of spontaneous circulation and further survival was still inconclusive in the current dataset.

Background: Cardiac symptoms are a characteristic feature of chronic obstructive pulmonary disease (COPD), a disorder with lately achieved recognition as a systemic illness according to established standards. The research's objective was aimed at investigating the transthoracic echocardiography role in assessing right ventricular (RV) dysfunction among individuals diagnosed with COPD, as well as to examine the potential correlation between blood pro B-type natriuretic peptide (BNP) concentrations + and this diagnostic procedure. Methods: Arterial blood gasses, spirometry, echocardiography, and serum pro BNP were done for 80 COPD patients and 20 healthy smokers, and some echocardiographic parameters were correlated with degree of airflow limitation. Results: 77.5% of COPD cases exhibited pulmonary hypertension (PHTN), and on classifying our COPD patients, it was found that 65% of patients in group II had PHTN and 90% of patients in group III had PHTN. Systolic pulmonary artery pressure (SPAP), mean pulmonary arterial pressure (MPAP), right ventricular mid diameter (RVMD), right ventricular basal diameter (RVBD), right ventricular longitudinal diameter (RVLD), right ventricular outflow tract (RVOT) above pulmonary and aortic valve, and tricuspid annular plane systolic excursion (TAPSE) along with RVEF exhibited a significant variance among all groups. A negative correlation was observed among forced expiratory volume (FEV) 1% and (RVMD as well as RVBD) and between Pro BNP and (TAPSE and RVEF). Conclusions: PHTN was found in 77.5% of COPD patients and is negatively correlated with FEV1%. Serum pro BNP level exhibits a negative correlation with FEV1% in stable COPD patients.

Objective Patients with Behçet's disease (BD) may experience long-term morbidity caused by various forms of cardiovascular disease. This study aimed to assess the risk for cardiovascular comorbidity in paediatric BD patients with and without vascular involvement, independent of the contribution of traditional risk factors. Methods Paediatric patients classified as having BD according to the 2015 Peadiatric BD (PEDBD) criteria were included in the study. Twenty-four-hour ambulatory blood pressure monitoring (ABPM), transthoracic echocardiography, and carotid intima-media thickness (cIMT) measurements were performed. Patients with an active disease or those who have other known risk factors for cardiovascular disease were not included in the study. Results Thirty-one children and adolescents with paediatric BD (16 female, 51.6%; F/M: 1.06) were enrolled in the study. Among the BD patients, 10 patients (34.4%) had abnormal ABPM. Carotid IMT values, mean arterial pressure, systolic and diastolic blood pressure by ABPM and the prevalence of abnormal ABPM, non-dipping, and ambulatory hypertension were similar between patients with and without vascular involvement. The echocardiography measurements showed that BD patients with vascular involvement had a significantly higher velocity and velocity time integral of the left ventricle outflow tract, which may indicate increased stiffness of the aorta. Conclusion Paediatric BD patients with vascular involvement may tend to have more cardiovascular risk factors. However, cardiovascular assessment should be considered in all BD patients, regardless of the involved systems. We suggest that ABPM may accurately define hypertension and cardiovascular risk in BD.

Background: Calcified amorphous tumor (CAT) of the heart is a rare, non-neoplastic cardiac mass with mitral valves and annuli being the most common sites. The presence of mitral annular calcification (MAC) is associated with an increased risk of stroke or other systemic embolisms. Here, we report a case of CAT showing rapid growth with MAC and investigate the link between the two. Case presentation: A 71-year-old man presented at our hospital with dyspnea and had been undergoing hemodialysis for 26 years for chronic glomerulonephritis. Transthoracic echocardiography (TTE) revealed moderate mitral stenosis with bulky MAC. Two months later, the patient developed progressive dyspnea, and follow-up TTE revealed a highly mobile mass (8 × 5 mm) attached to the left ventricular (LV) side of the posterior MAC. He underwent surgery because of congestive heart failure and a high risk of embolization. Surgical inspection revealed that the tumor was attached beneath the P3 segment of the mitral valve on the LV side and was removed. When removing the MAC, toothpaste-like contents drained from the encapsulated mass inside the MAC at the P3 segment, where the tumor was located. After reconstructing the posterior mitral annulus defect with a bovine pericardial patch, mitral valve replacement with a mechanical prosthesis, a maze procedure, and left appendage closure were performed. Histopathological examination revealed that the excised tumor contained fibrin and calcium deposits. The mass was diagnosed as a CAT. Conclusions: CAT may be one of the causes of stroke induced by MAC. Routine follow-up echocardiography should be recommended for patients with MAC, especially those undergoing hemodialysis.

- Abstract
Background: Right ventricular dysfunction (RVD) is the main determinant of mortality in patients with pulmonary embolism (PE). Thus, guidelines recommend the assessment of RVD with transthoracic echocardiography (TTE) or computed tomography pulmonary angiography (CTPA) among these patients. In this study, we investigated the agreement between TTE and CTPA for the detection of RVD. Methods: This single-center retrospective study included patients who were diagnosed with CTPA and underwent TTE within the fir t 24 hours following the diagnosis. Results: Two hundred fift -eight patients met the inclusion criteria. In 71.3% (184) of them, CTPA and TTE agreed on both the presence and absence of RVD. There was a moderate agreement between the 2 tests (Cohen's kappa = 0.404, P < .001). The agree- ment between right ventricle dysfunction on TTE and the increased right ventricle/left ventricle (RV/LV) on CTPA was fair (Cohen's kappa = 0.388, P < .001). Three patients died due to PE, and another 5 patients required urgent reperfusion therapy. Overall, adverse outcomes occurred in 4% (8) of patients. The sensitivity of modalities in the detection of adverse outcomes was 100%. Transthoracic echocardiography was more specific compared to CTPA (43% vs. 28%). Statistically, flattening/bulging of the interventricular septum on TTE was significantly associated with adverse outcomes. No individual CTPA parameter was related to adverse outcomes. Conclusion: Both CTPA and TTE are reliable imaging modalities in the detection of RVD. However, TTE is more specific, and this may help in the identifi ation and appropriate management of patients at higher risk of decompensation. A combination of CTPA parameters rather than individual RV/LV ratios increases the sensitivity of CTPA. [ABSTRACT FROM AUTHOR]

- Abstract
The maximum blood flow velocity through the aortic valve (AVmax) using Doppler transthoracic echocardiography (TTE) is important in assessing the severity of aortic stenosis (AS). The right parasternal (RP) approach has been reported to be more useful than the apical approach, but the anatomical rationale has not been studied. We aimed to clarify the influence of the angle formed by the ascending aorta and left ventricle on Doppler analysis by TTE (Sep-Ao angle) and three-dimensional multidetector computed tomography (3D-MDCT) in patients with AS. A total of 151 patients evaluated using the RP approach and 3D-MDCT were included in this study. The Sep-Ao angle determined using TTE was compared with that determined using 3D-MDCT analysis. In MDCT analysis, the left ventricular (LV) axis was measured in two ways and the calcification score was calculated simultaneously. The Sep-Ao angle on TTE was consistent with that measured using 3D-MDCT. In patients with an acute Sep-Ao angle, the Doppler angle in the apical approach was larger, potentially underestimating AVmax. Multivariate analysis revealed that an acute Sep-Ao angle, large Doppler angle in the apical approach, smaller Doppler angle in the RP approach, and low aortic valve calcification were independently associated with a higher AVmax in the RP approach than in the apical approach. The Sep-Ao angle measured using TTE reflected the 3D anatomical angle. In addition to measurements using the RP approach, technical adjustments to minimize the Doppler angle to avoid bulky calcification should always be noted for accurate assessment.

Background: The objective was to assess the agreement between therapeutic proposals derived from basic critical care echocardiography performed by novice operators in ultrasonography after a limited training (residents) and by experts considered as reference. Secondary objectives were to assess the agreement between operators' answers to simple clinical questions and the concordance between basic two-dimensional measurements. Methods: This observational, prospective, single-center study was conducted over a 3-year period in a medical-surgical intensive care unit. Adult patients with acute circulatory and/or respiratory failure requiring a transthoracic echocardiography (TTE) examination were studied. In each patient, a TTE was performed by a resident novice in ultrasonography after a short training program and by an expert, independently but within 1 h and in random order. Each operator addressed standardized simple clinical questions and subsequently proposed a therapeutic strategy based on a predefined algorithm. Results: Residents performed an average of 33 TTE studies in 244 patients (156 men; age: 63 years [52–74]; SAPS2: 45 [34–59]; 182 (75%) mechanically ventilated). Agreement between the therapeutic proposals of residents and experienced operators was good-to-excellent. The concordance was excellent for suggesting fluid loading, inotrope or vasopressor support (all Kappa values > 0.80). Inter-observer agreement was only moderate when considering the indication of negative fluid balance (Kappa: 0.65; 95% CI 0.50–0.80), since residents proposed diuretics in 23 patients (9.5%) while their counterparts had the same suggestion in 35 patients (14.4%). Overall agreement of responses to simple clinical questions was also good-to-excellent. Intraclass correlation coefficient exceeded 0.75 for measurement of ventricular and inferior vena cava size. Conclusions: A limited training program aiming at acquiring the basic level in critical care echocardiography enables ICU residents novice in ultrasonography to propose therapeutic interventions with a good-to-excellent agreement with experienced operators.

Background: Blunt traumatic aortic injury (BTAI) is the second leading cause of death due to traumas in young patients. The primary presentation might be chest or interscapular pain, difficulty in breathing, and, in severe cases, hypotension. Considering the rapid deterioration of these patients' clinical conditions, prompt diagnosis and treatment initiation are crucial. In these injuries, the most involved parts of the aorta are the isthmus (distal to the left subclavian artery) and the descending part in the thorax. Therefore, the main diagnostic strategies include transthoracic echocardiography, CT angiography, and endovascular diagnostic approaches. Case presentation The patient was a 19-year-old male presenting with the symptoms of chest pain, dyspnea, and extremities excruciating pain after a car turnover. The initial evaluation showed no abnormal cardiovascular finding except bilateral hemothorax, addressed with chest tubes. Twelve hours later, when the patient was under observation for orthopedic surgeries, his chest pain and dyspnea started, and TTE and CTA showed a grade three descending aneurysm of the aorta. The patient was treated immediately with an endovascular procedure of stent implantation. A delayed debranching surgery was also performed, which resulted in desirable outcomes and uneventful follow-up. Conclusion: Although open thoracic surgery is the main and almost the only option for treating aneurysms of the aorta in hemodynamically unstable patients, the endovascular procedure has shown superior outcomes in selected patients with appropriate anatomy. Debranching surgery, which can be done simultaneously or with delay after the initial procedure, has proven protective against thromboembolic cerebral events. Clinical key point: Patients with an aneurysm of the aorta should be transported to a medical center with a multidisciplinary team for an urgent evaluation and treatment. The initial resuscitation and diagnosis are challenging, considering the fatal nature of these injuries, and the selection of the treatment is based on the patient's clinical condition and evaluated anatomy in cardiovascular imaging.

Purpose: For novice learners, converting two-dimensional (2D) images of echocardiography to three-dimensional (3D) cardiac structures is deemed challenging. This study aimed to develop an accurate dissection method of the heart to reproduce the transthoracic echocardiographic views on cadavers and elucidate new educational methods in human anatomy dissection courses. Methods: A total of 18 hearts were used in this study. After reflecting the anterior thoracic wall inferiorly, the hearts were excised from embalmed cadavers. Thereafter, three landmarks were set on the heart for each plane of the incision, and the hearts were incised to observe the three different echocardiographic views, which include the apical four-chamber view (A4C), parasternal long axis (PLAX) view, and parasternal short axis (PSAX) view at the papillary muscle level. If all structures for observation during routine echocardiography are clearly observed in each view, a successful incision is considered. All procedures and incisions were performed by the medical students. After a successful incision, hearts were returned to the original position in the pericardial sac for further observation. Results: The success rates of incision for each view were 83.3% (5/6 success cases), 83.3% (5/6 success cases), and 66.7% (4/6 success cases) in the A4C view, PLAX view, and PSAX view at the papillary muscle level, respectively. Conclusion: This dissection method could probably be employed to reproduce transthoracic echocardiographic views on cadaveric hearts, which is beneficial for novice learners for a deeper understanding of the anatomy.

Infective endocarditis is a rare disease with an increasing incidence and an unaltered high mortality rate, despite medical development. Imaging plays an integrative part in the diagnosis of infective endocarditis, with echocardiography as the initial diagnostic test. Research data in the utility of cardiac computed tomography (CCT) in the diagnostic algorithm of IE are rising, which indicates its importance in detection of IE-related lesion along with the exclusion of coronary artery disease. The latest 2023 European Society of Cardiology Guidelines in the management of IE classified CCT as class of recommendation I and level of evidence B in detection of both valvular and paravalvular lesions in native and prosthetic valve endocarditis. This review article provides a comprehensive and contemporary review of the role of CCT in the diagnosis of IE, the optimization of acquisition protocols, the morphology characteristics of IE-related lesions, the published data of the diagnostic performance of CCT in comparison to echocardiography as the state-of-art method, as well as the limitations and future possibilities.

Cor triatriatum dexter is a rare congenital heart anomaly in which the right atrium is divided into 2 chambers by a membrane. Clinical manifestations vary depending on the degree of the right atrium separation and the presence of concomitant anomalies. We report a case of asymptomatic cor triatriatum dexter diagnosed during transthoracic echocardiography. The diagnosis was confirmed by transesophageal echocardiography, computed tomography, and magnetic resonance imaging. Transthoracic echocardiography is a sensitive primary diagnostic tool for such congenital heart disease as cor triatriatum dexter.

Abstract Background Blunt traumatic aortic injury (BTAI) is the second leading cause of death due to traumas in young patients. The primary presentation might be chest or interscapular pain, difficulty in breathing, and, in severe cases, hypotension. Considering the rapid deterioration of these patients’ clinical conditions, prompt diagnosis and treatment initiation are crucial. In these injuries, the most involved parts of the aorta are the isthmus (distal to the left subclavian artery) and the descending part in the thorax. Therefore, the main diagnostic strategies include transthoracic echocardiography, CT angiography, and endovascular diagnostic approaches. Case presentation The patient was a 19-year-old male presenting with the symptoms of chest pain, dyspnea, and extremities excruciating pain after a car turnover. The initial evaluation showed no abnormal cardiovascular finding except bilateral hemothorax, addressed with chest tubes. Twelve hours later, when the patient was under observation for orthopedic surgeries, his chest pain and dyspnea started, and TTE and CTA showed a grade three descending aneurysm of the aorta. The patient was treated immediately with an endovascular procedure of stent implantation. A delayed debranching surgery was also performed, which resulted in desirable outcomes and uneventful follow-up. Conclusion Although open thoracic surgery is the main and almost the only option for treating aneurysms of the aorta in hemodynamically unstable patients, the endovascular procedure has shown superior outcomes in selected patients with appropriate anatomy. Debranching surgery, which can be done simultaneously or with delay after the initial procedure, has proven protective against thromboembolic cerebral events. Clinical key point Patients with an aneurysm of the aorta should be transported to a medical center with a multidisciplinary team for an urgent evaluation and treatment. The initial resuscitation and diagnosis are challenging, considering the fatal nature of these injuries, and the selection of the treatment is based on the patient's clinical condition and evaluated anatomy in cardiovascular imaging.

There is emerging evidence that the cardiac interatrial septum has an important role as a thromboembolic source for ischemic strokes. There is little consensus on treatment of patients with different cardiac interatrial morphologies or pathologies who have had stroke. In this paper, we summarize the important background, diagnostic, and treatment considerations for this patient population as presented during the Federation of American Societies for Experimental Biology (FASEB) Virtual Catalytic Conference on the Cardiac Interatrial Septum and Stroke Risk, held on December 7, 2022. During this conference, many aspects of the cardiac interatrial septum were discussed. Among these were the embryogenesis of the interatrial septum and development of anatomic variants such as patent foramen ovale and left atrial septal pouch. Also addressed were various mechanisms of injury such as shunting physiologies and the consequences that can result from anatomic variants, as well as imaging considerations in echocardiography, computed tomography, and magnetic resonance imaging. Treatment options including anticoagulation and closure were addressed, as well as an in-depth discussion on whether the left atrial septal pouch is a stroke risk factor. These issues were discussed and debated by multiple experts from neurology, cardiology, and radiology.

Abstract Aims Anthracycline chemotherapy (AC) for breast cancer can cause cancer therapy‐related cardiac dysfunction (CTRCD) with resultant heart failure, traditionally defined as a reduction in left ventricular (LV) ejection fraction on echocardiography. In recent years, global longitudinal systolic strain (GLS) has been used to identify subclinical cardiac dysfunction prior to development of overt CTRCD. Recent harmonized guidelines have incorporated GLS into definitions for CTRCD to identify cardiac dysfunction and inform decisions regarding cardioprotective strategies. Methods and results We evaluated subclinical dysfunction in breast cancer patients treated with AC and determined the echocardiographic and patient factors associated with significant GLS changes. One hundred fourteen HER2 negative patients treated with AC were prospectively recruited and underwent serial echocardiograms (LVEF and LVGLS) at three time points (prior to AC, 3 months, and 1 year). CTRCD was defined as an asymptomatic reduction in LVEF of 10% or symptomatic drop of 5% to LVEF

- Abstract
Aims: Anthracycline chemotherapy (AC) for breast cancer can cause cancer therapy‐related cardiac dysfunction (CTRCD) with resultant heart failure, traditionally defined as a reduction in left ventricular (LV) ejection fraction on echocardiography. In recent years, global longitudinal systolic strain (GLS) has been used to identify subclinical cardiac dysfunction prior to development of overt CTRCD. Recent harmonized guidelines have incorporated GLS into definitions for CTRCD to identify cardiac dysfunction and inform decisions regarding cardioprotective strategies. Methods and results: We evaluated subclinical dysfunction in breast cancer patients treated with AC and determined the echocardiographic and patient factors associated with significant GLS changes. One hundred fourteen HER2 negative patients treated with AC were prospectively recruited and underwent serial echocardiograms (LVEF and LVGLS) at three time points (prior to AC, 3 months, and 1 year). CTRCD was defined as an asymptomatic reduction in LVEF of 10% or symptomatic drop of 5% to LVEF <53%. Subclinical LV dysfunction was defined as a reduction of ≥10% in GLS compared with baseline, recognizing that this cut off identified an 'at risk cohort' rather than patients with established CTRCD. No participant demonstrated CTRCD by reduction in LVEF. Forty‐three patients (38%) demonstrated a ≥10% relative reduction in GLS at 12 months; 20/43 (47%) had a reduced absolute GLS to <16%, and were older, had hypertension, increased LV mass, lower baseline e′ velocity and GLS. GLS ≥20.5% at baseline yielded a sensitivity of 79% and specificity of 87% for a normal GLS (i.e., ≥16%) at 1 year despite a ≥10% reduction from baseline. Conclusions: We present a stepwise evaluation for subclinical LV dysfunction using both a relative reduction in GLS combined with an absolute reduction in GLS. We believe our findings may re‐stratify patients with a high baseline GLS into a lower risk group despite transient relative GLS decrements ≥10%. [ABSTRACT FROM AUTHOR]

Abstract Tricuspid annular disjunction (TAD) is concomitant in approximately half of mitral annular disjunction (MAD) cases. Here we report a case of echocardiographically isolated TAD detected during Takotsubo syndrome (TTS) complicated by a transient aggravation of tricuspid regurgitation. An 87‐year‐old female was admitted at the emergency department with ST segment elevation. Coronary angiography findings were consistent with TTS. Transthoracic echocardiography (TTE) showed a left ventricular apical aneurysm with incidental finding of TAD with ‘torrential’ tricuspid regurgitation. Importantly, no concomitant MAD was detected on TTE. No significant arrhythmias were detected on telemetry surveillance. Follow up TTE showed improvement in left ventricular function with reduced regional wall abnormalities. TAD was still present although the tricuspid regurgitation had reduced to ‘moderate’. The patient was discharged home after 23 days of hospital stay. The present case illustrates the need of further investigations into TAD and its clinical implications for acute TR in TTS.

Background: Given the limited access to invasive vasospastic reactivity testing in Western Countries, there is a need to further develop alternative non‐invasive diagnostic methods for vasospastic angina (VSA). Hyperventilation testing (HVT) is defined as a class IIa recommendation to diagnose VSA by the Japanese Society of Cardiology. Methods: In this systematic review and meta‐analysis reported according to the PRISMA statement, we review the mechanisms, methods, modalities and diagnostic accuracy of non‐invasive HVT for the diagnostic of VSA. Results: A total of 106 articles published between 1980 and 2022 about VSA and HVT were included in the systematic review, among which 16 were included in the meta‐analysis for diagnostic accuracy. Twelve electrocardiogram‐HVT studies including 804 patients showed a pooled sensitivity of 54% (95% confidence intervals [CI]; 30%–76%) and a pooled specificity of 99% (95% CI; 88%–100%). Four transthoracic echocardiography‐HVT studies including 197 patients revealed a pooled sensitivity of 90% (95% CI; 82%–94%) and a pooled specificity of 98% (95% CI; 86%–100%). Six myocardial perfusion imaging‐HVT studies including 112 patients yielded a pooled sensitivity of 95% (95% CI; 63%–100%) and a pooled specificity of 78% (95% CI; 19%–98%). Non‐invasive HVT resulted in a low rate of adverse events, ventricular arrhythmias being the most frequently reported, and were resolved with the administration of nitroglycerin. Conclusions: Non‐invasive HVT offers a safe alternative with high diagnostic accuracy to diagnose VSA in patients with otherwise undiagnosed causes of chest pain. [ABSTRACT FROM AUTHOR]

Transthoracic echocardiography (TTE) is the most widely available and utilised imaging modality for the screening, diagnosis, and serial monitoring of all abnormalities related to cardiac structure or function. The primary objectives of this document are to provide (1) a guiding framework for treating clinicians of the acceptable indications for the initial and serial TTE assessments of the commonly encountered cardiovascular conditions in adults, and (2) the minimum required standard for TTE examinations and reporting for imaging service providers. The main areas covered within this Position Statement pertain to the TTE assessment of the left and right ventricles, valvular heart diseases, pericardial diseases, aortic diseases, infective endocarditis, cardiac masses, pulmonary hypertension, and cardiovascular diseases associated with cancer treatments or cardio-oncology. Facilitating the optimal use and performance of high quality TTEs will prevent the over or under-utilisation of this resource and unnecessary downstream testing due to suboptimal or incomplete studies.

- Abstract
Pulmonary arteriovenous malformations (PAVMs) occur in 30% to 50% of patients with hereditary hemorrhagic telangiectasia. Clinical presentations vary from asymptomatic disease to complications resulting from the right to left shunting of blood through the PAVM such as paradoxical stroke, brain abscesses, hypoxemia, and cardiac failure. Radiology plays an important role both in the diagnosis and treatment of PAVM. Based on different clinical scenarios, the appropriate imaging study has been reviewed and is presented in this document. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation. [ABSTRACT FROM AUTHOR]

Background Primary pericardial sarcomas are extremely rare malignancies. In this case of primary pericardial synovial sarcoma, we discuss the initial steps to work-up pericardial effusions and review features that warrant more detailed investigation. Case summary A 29-year-old male with no relevant past medical history presents with a few weeks of fatigue, dyspnoea, orthopnoea, leg swelling, and back pain. Transthoracic echocardiogram revealed pericardial effusion for which pericardiocentesis and drain placement were done. He was discharged with a diagnosis of post-viral pericarditis. He returned 5 months later with worsening symptoms. Advanced imaging with cardiac magnetic resonance imaging (CMR) showed heterogeneous pericardial mass later revealed to be a high-grade synovial sarcoma on biopsy. The patient was started on a doxorubicin-based chemotherapy regimen, but due to kidney dysfunction and multi-organ failure, he was transitioned to palliative care measures. Discussion Transthoracic echocardiogram and computed tomography are often the initial tests of choice for pericardial effusions with pericardiocentesis recommended for effusions with tamponade physiology, for moderate-to-large effusions, or if there is concern for infection/neoplasm. Due to improved tissue characterization and spatial resolution, CMR and positron emission tomography should also be considered for atypical or recurrent pericardial effusions to assess for less common aetiologies such as malignancy.

Cardiovascular disease (CVD) is the leading cause of death worldwide, but prevalence estimates in former professional athletes are limited. HUDDLE (Heart Health: Understanding and Diagnosing Disease by Leveraging Echocardiograms) aimed to raise awareness and estimate the prevalence of CVD and associated risk factors among members of the National Football League (NFL) Alumni Association and their families through education and screening events. HUDDLE was a multicity, cross-sectional study of NFL alumni and family members aged 50 years and older. Subjects reported their health history and participated in CVD education and screening (blood pressure, electrocardiogram, and transthoracic echocardiogram [TTE] assessments). Phone follow-up by investigators occurred 30 days postscreening to review results and recommendations. This analysis focuses on former NFL athletes. Of 498 participants screened, 57.2% (N = 285) were former NFL players, the majority of whom were African American (67.6%). The prevalence of hypertension among NFL alumni was estimated to be 89.8%, though only 37.5% reported a history of hypertension. Of 285 evaluable participants, 61.8% had structural cardiac abnormalities by TTE. Multivariable analysis showed that hypertension was a significant predictor of clinically relevant structural abnormalities on TTE. HUDDLE identified a large discrepancy between participant self-awareness and actual prevalence of CVD and risk factors, highlighting a significant opportunity for population health interventions. Structural cardiac abnormalities were observed in most participants and were independently predicted by hypertension, affirming the role of TTE for CVD screening in this population aged older than 50 years.

- Abstract
Primary cardiac lymphoma is an exceedingly rare malignant tumor, with diffuse large B-cell lymphoma (DLBCL) being the most prevalent histological subtype. This disease has non-specific clinical manifestations, making early diagnosis crucial. However, DLBCL diagnosis is commonly delayed, and its prognosis is typically poor. Herein, we report the case of a 51-year-old male patient with DLBCL who presented with recurrent chest tightness for 4 months as the primary clinical symptom. The patient was admitted to the hospital and diagnosed with acute myocardial infarction and left ventricular hypertrophy with heart failure. Echocardiography revealed a progression from left ventricular thickening to local pericardial thickening and adhesion in the inferior and lateral walls of the left ventricle. Finally, pathological analysis of myocardial biopsy confirmed the diagnosis of DLBCL. After treatment with the R-CHOP chemotherapy regimen, the patient's chest tightness improved, and he was discharged. After 2 months, the patient succumbed to death owing to sudden ventricular tachycardia, ventricular fibrillation, and decreased blood pressure despite rescue efforts. Transthoracic echocardiography is inevitable for the early diagnosis of DLBCL, as it can narrow the differential and guide further investigations and interventions, thereby improving the survival of these patients.

Background: Single atrium is very rare congenital cardiac anomaly in adults. The prognosis of patients with single atrium is very poor, with 50% of patients dying owing to cardiopulmonary complications in childhood. Herein, we focused on anesthesia management for noncardiac surgery in patients with single atrium. Case presentation: A 58-year-old male with a history of bilateral varicocele underwent laparotomy for high-position ligation of the spermatic vein. The patient also had a history of single atrium, atrial fibrillation, chronic heart failure, pulmonary hypertension (PH), and complete right bundle branch block (CRBBB). Given the significant complications associated with general anesthesia in patients with PH, we preferred to use low-dose epidural anesthesia for this patient. Transthoracic echocardiography was used to assess cardiac function before and during surgery and guide perioperative fluid therapy. To limit the stress response, we used a regional nerve block for reducing postoperative pain. Furthermore, we used norepinephrine to appropriately increase the systemic vascular resistance in response to the reduction of systemic vascular resistance caused by epidural anesthesia. Conclusion: Low-dose epidural anesthesia can be safely used in patients with single atrium and PH. The use of perioperative transthoracic echocardiography is helpful in guiding fluid therapy and effectively assessing the cardiac structure and function of patients. Prophylactic administration of norepinephrine before epidural injection may make it easier to maintain the patient's BP. [ABSTRACT FROM AUTHOR]

Introduction: Left bundle branch pacing (LBBP) is a physiological pacing modality. However, the long procedure and fluoroscopy time of LBBP is still a problem. This study aims to compare the clinical outcomes between transthoracic echocardiography (TTE)‐ and X‐ray‐guided LBBP. Methods: This is a single‐center, prospective, randomized controlled study. Consecutive patients who underwent LBBP in our team from June 2022 to November 2022 were enrolled. Procedure and fluoroscopy time, pacing parameters, electrophysiological and echocardiographic characteristics, as well as complications were recorded at implantation and during follow‐up. Results: In this study, 60 patients were enrolled and divided into two groups: 30 patients were allocated to the X‐ray group and the remaining 30 to the TTE group. There was no significant difference in the success rate between the two groups (86.7% vs. 76.7%, p = .317). The procedure time of TTE group was comparable to that of the X‐ray group (9.0 vs. 12.0 min, p = .063). However, the fluoroscopy time in the TTE group was significantly lower than that of the X‐ray group (2.5 vs. 5.0 min, p = .002). There were no statistically significant differences in pacing parameters, electrophysiological and echocardiographic characteristics, or complications between the two groups at implantation and during follow‐up. Conclusion: TTE‐guided LBBP is a feasible and safe method. Compared with X‐ray, TTE showed a comparable success rate and procedure time, but it could significantly reduce the fluoroscopy time of LBBP. [ABSTRACT FROM AUTHOR]

Objective: To compare the effectiveness of transthoracic echocardiography (TTE) and X-ray guided closure of patent foramen ovale (PFO). Methods: In this retrospective study, clinical data from 90 patients who underwent PFO occlusion surgery in the First People's Hospital of Yongkang from January 2020 to December 2022 were retrospectively reviewed. Among them, 43 patients underwent X-ray guided PFO occlusion surgery (X-ray group) while 47 patients underwent TTE guided PFO occlusion surgery (TTE group). Perioperative, cardiac function related indicators were measured before and after treatment, along with right-to-left shunting status, and incidence of complications in both groups. Results: There was no significant difference in the duration of surgery or hospitalization between the TTE group and the X-ray group (p>0.05). After treatment, the cardiac function indicators of both groups increased compared to before treatment (p<0.05), and there was no significant difference between the groups (p>0.05). After treatment, right-to-left shunting in the two groups improved compared to before treatment (p<0.05), with no significant difference between the groups (p>0.05). There was no significant difference in complications between the two groups (p>0.05). Conclusions: TTE guided PFO occlusion is as effective as X-ray guided PFO occlusion in the treatment of PFO. TTE surgery is clinically beneficial for reducing radiation damage with a good safety profile. [ABSTRACT FROM AUTHOR]

Valvular heart diseases (VHDs) pose a significant public health burden, and deciding the best treatment strategy necessitates accurate assessment of heart valve function. Transthoracic echocardiography (TTE) is the key modality to evaluate VHDs, but the lack of standardized quantitative measurements leads to subjective and time-consuming assessments. We aimed to use deep learning to automate the extraction of mitral valve (MV) leaflets and annular hinge points from echocardiograms of the MV, improving standardization and reducing workload in quantitative assessment of MV disease. We annotated the MV leaflets and annulus points in 2931 images from 127 patients. We propose an approach for segmenting the annotated features using Attention UNet with deep supervision and weight scheduling of the attention coefficients to enforce saliency surrounding the MV. The derived segmentation masks were used to extract quantitative biomarkers for specific MV leaflet scallops throughout the heart cycle. Evaluation performance was summarized using a Dice score of 0.63 ± 0.14, annulus error of 3.64 ± 2.53 and leaflet angle error of 8.7 ± 8.3°. Leveraging Attention UNet with deep supervision robustness of clinically relevant metrics was improved compared with UNet, reducing standard deviations by 2.7° (angle error) and 0.73 mm (annulus error). We correctly identified cases of MV prolapse, cases of stenosis and healthy references from a clinical material using the derived biomarkers. Robust deep learning segmentation and tracking of MV morphology and motion is possible by leveraging attention gates and deep supervision, and holds promise for enhancing VHD diagnosis and treatment monitoring.

Background A coronary artery aneurysm is a rare cardiac anomaly that may be incidentally detected on echocardiography. When associated with a coronary cameral fistula, an aneurysm can become symptomatic. We present a unique case of a giant left circumflex coronary aneurysm with a fistula to the left atrium and a large atrial septal defect causing acute heart failure in a young woman during the peripartum period. Case summary A 32 year-old woman who presented with hypoxia after the delivery of her fourth child was found to have heart failure with severe mitral regurgitation and multiple abnormal intracardiac shunts. Echocardiography showed a large circular structure with Doppler color flow into the left atrium and between the atria. Cardiac computed tomography showed multiple dilated coronary arteries including a left circumflex coronary artery aneurysm measuring >10 cm in diameter with fistulous communication to the left atrium and a large atrial septal defect. A right heart catheterization was performed, and the patient was diagnosed with high-output heart failure. Surgical closure of the coronary cameral fistula was deferred due to the risk of worsening pressure in the coronary aneurysm, and the patient was referred for cardiac transplantation. Discussion This case illustrates severe heart failure as a complication of a giant coronary artery aneurysm with fistulization to the left atrium and subsequent shunting through a large atrial defect. Echocardiography allows for the detection of a coronary aneurysm and shunting, and cardiac computed tomography provides detailed visualization of a coronary cameral fistula. [ABSTRACT FROM AUTHOR]

Background: Quadricuspid aortic valve (QAV) is a rare congenital disease. The clinical characteristics of this disease remain unclear except for those in relatively young patients reported from tertiary referral hospitals. The aim of this study was to determine the clinical features of QAV in a regional population. Methods and Results: We retrospectively investigated 25 340 consecutive patients over middle age (median age, 73 (IQR 65-80) years; range, 45-102 years) who underwent transthoracic echocardiography (TTE) at our institute during the period from April 2008 to December 2023. Eight (0.032%) of the patients (median age, 65 years; range, 47-91 years) were diagnosed withQAV. Six patients suffered from aortic regurgitation (AR), and one patient had mild aortic stenosis at the time of QAVd iagnosis. Two patients who had severe AR at referral underwent aortic valve surgery. The severity of AR in the other patients was moderate or less. During a median follow-up period of 27 months (range, 1-171 months), none of the patients other than above two patients had cardiac events. One patient died from a non-cardiac cause at 94 years of age. Conclusions: Patients diagnosed with QAV after middle age, who do not exhibit severe valve insufficiency at the time of diagnosis, may not experience worse clinical outcomes. However, further research is required for a better understanding of the long-term outcomes. [ABSTRACT FROM AUTHOR]

HEART failure , *HEART assist devices , *NATRIURETIC peptides , *VENTRICULAR ejection fraction - Abstract
Aims: Heart failure (HF) outcomes remain poor despite optimal guideline‐directed medical therapy (GDMT). We assessed safety, effectiveness, and transthoracic echocardiographic (TTE) outcomes during the 12 months after Ventura shunt implantation in the RELIEVE‐HF open‐label roll‐in cohort. Methods and results: Eligibility required symptomatic HF despite optimal GDMT with ≥1 HF hospitalization in the prior year or elevated natriuretic peptides. The safety endpoint was device‐related major adverse cardiovascular or neurological events at 30 days, compared to a prespecified performance goal. Effectiveness evaluations included the Kansas City Cardiomyopathy Questionnaire (KCCQ) at baseline, 1, 3, 6, and 12 months and TTE at baseline and 12 months. Overall, 97 patients were enrolled and implanted at 64 sites. Average age was 70 ± 11 years, 97% were in New York Heart Association class III, and half had left ventricular ejection fraction (LVEF) ≤40%. The safety endpoint was achieved (event rate 0%, p < 0.001). KCCQ overall summary score was improved by 12–16 points at all follow‐up timepoints (all p < 0.004), with similar outcomes in patients with reduced and preserved LVEF. At 12 months, left ventricular end‐systolic and end‐diastolic volumes were reduced (p = 0.020 and p = 0.038, respectively), LVEF improved (p = 0.009), right ventricular end‐systolic and end‐diastolic areas were reduced (p = 0.001 and p = 0.030, respectively), and right ventricular fractional area change (p < 0.001) and tricuspid annular plane systolic excursion (p < 0.001) improved. Conclusion: Interatrial shunting with the Ventura device was safe and resulted in favourable clinical effects in patients with HF, regardless of LVEF. Improvements of left and right ventricular structure and function were consistent with reverse myocardial remodelling. These results would support the potential of this shunt device as a treatment for HF. [ABSTRACT FROM AUTHOR]

ECHOCARDIOGRAPHY , *RAYLEIGH waves , *ARTIFICIAL intelligence , *TIME measurements - Abstract
Background: Transthoracic echocardiography (TTE) is the gold standard modality for evaluating cardiac morphology, function, and hemodynamics in clinical practice. While artificial intelligence (AI) is expected to contribute to improved accuracy and is being applied clinically, its impact on daily clinical practice has not been fully evaluated. Methods: We retrospectively examined 30 consecutive patients who underwent AI-equipped TTE at a single institution. All patients underwent manual and automatic measurements of TTE parameters using the AI-equipped TTE. Measurements were performed by three sonographers with varying experience levels: beginner, intermediate, and expert. Results: A comparison between the manual and automatic measurements assessed by the experts showed extremely high agreement in the left ventricular (LV) filling velocities (E wave: r = 0.998, A wave: r = 0.996; both p < 0.001). The automated measurements of LV end-diastolic and end-systolic diameters were slightly smaller (−2.41 mm and −1.19 mm) than the manual measurements, although without significant differences, and both methods showing high agreement (r = 0.942 and 0.977, both p < 0.001). However, LV wall thickness showed low agreement between the automated and manual measurements (septum: r = 0.670, posterior: r = 0.561; both p < 0.01), with automated measurements tending to be larger. Regarding interobserver variabilities, statistically significant agreement was observed among the measurements of expert, intermediate, and beginner sonographers for all the measurements. In terms of measurement time, automatic measurement significantly reduced measurement time compared to manual measurement (p < 0.001). Conclusions: This preliminary study confirms the accuracy and efficacy of AI-equipped TTE in routine clinical practice. A multicenter study with a larger sample size is warranted.

SEPTIC shock , *CARDIAC output , *CRITICAL care medicine , *ECHOCARDIOGRAPHY , *CRITICALLY ill - Abstract
Background: Cardiac output (CO) measurement is essential for guiding therapeutic decisions in critically ill patients. Electrical cardiometry (EC), which is based on thoracic electrical bioimpedance, can measure CO in a continuous and noninvasive way. The benefits of EC are continuous monitoring, low time consumption, portability, and user independence. Transthoracic echocardiography has been a noninvasive method to assess CO despite being noncontiguous and operator dependent. Aim: This study aimed to compare EC and echocardiography (Echo) in measuring CO in septic shock patients and assess the reliability and accuracy of EC for noninvasive CO monitoring. Patients and methods: Fifty adult patients were admitted to the Critical Care Medicine Department, diagnosed with septic shock according to the surviving sepsis campaign, and fulfilling the inclusion and exclusion criteria from January 2023 to October 2023, and they were subjected to EC, Echo, and ECG recording. Results: There was a strong positive significant correlation between CO measurements by echo and EC (r=0.988, P<0.001), and there was a strong positive significant correlation between stroke volume (SV) measurements by echo and EC (r=0.999, P<0.001). Also, there was a strong positive significant correlation between SV and CO measured by both techniques (r=0.782, P<0.001) (r=0.790, P<0.001, respectively). Conclusion: Compared to Echo, EC can be used as a continuous, noninvasive method for monitoring CO and SV, as it provides accurate and reliable measurements. [ABSTRACT FROM AUTHOR]

HEART valve prosthesis implantation , *AORTIC stenosis , *HEMODYNAMICS , *DOPPLER ultrasonography , *AORTIC valve - Abstract
The corrected left ventricular ejection time (cLVET) comprises the phase from aortic valve opening to aortic valve closure corrected for heart rate. As a surrogate measure for cLVET, the corrected carotid flow time (ccFT) has been proposed in previous research. The aim of this study was to assess the clinical agreement between cLVET and ccFT in a dynamic clinical setting. Twenty-five patients with severe aortic valve stenosis (AS) were selected for transcatheter aortic valve replacement (TAVR). The cLVET and ccFT were derived from the left ventricular outflow tract (LVOT) and the common carotid artery (CCA), respectively, using pulsed wave Doppler ultrasound. Bazett's (B) and Wodey's (W) equations were used to calculate cLVET and ccFT. Measurements were performed directly before (T1) and after (T2) TAVR. Correlation, Bland–Altman and concordance analyses were performed. Corrected LVET decreased from T1 to T2 (p < 0.001), with relative reductions of 11% (B) and 9% (W). Corrected carotid flow time decreased (p < 0.001), with relative reductions of 12% (B) and 10% (W). The correlation between cLVET and ccFT was strong for B (ρ = 0.74, p < 0.001) and W (ρ = 0.81, p < 0.001). The bias was –39 ms (B) and –37 ms (W), and the upper and lower levels of agreement were 19 and –98 ms (B) and 5 and –78 ms (W), respectively. Trending ability between cLVET and ccFT was good (concordance 96%) for both B and W. In TAVR patients, the clinical agreement between cLVET and ccFT was acceptable, indicating that ccFT could serve as a surrogate measure for cLVET. [ABSTRACT FROM AUTHOR]

- Abstract
Echocardiographic imaging is the foundation for the evaluation of mitral valve dysfunction. Both transthoracic and transesophageal echocardiography provide insight into the anatomy, pathology, and classification mitral valve dysfunction. Echocardiography also provides a multi-parametric approach with semi-quantitative and quantitative parameters to assess the severity of mitral regurgitation and mitral stenosis. Transesophageal imaging is essential in the assessment of patients considered for surgical or transcatheter interventional strategies to treat mitral valve dysfunction. Cardiac computed tomography (CT) and cardiac MRI are useful adjunctive imaging techniques in mitral valve disease with CT providing detailed procedural specificity and MRI providing detailed ventricular and regurgitant flow analysis.

50. Right ventricular dilatation: echocardiographic differential diagnosis.

- Abstract
The initial means of detecting right ventricular (RV) dilatation is often transthoracic echocardiography (TTE), and once the presence of RV dilatation is suspected, there is the possibility of RV volume overload, RV pressure overload, RV myocardial disease, and even nonpathological RV dilatation. With respect to congenital heart disease with RV volume overload, defects or valvular abnormalities can be easily detected with TTE, with the exception of some diseases. Volumetric assessment using three-dimensional echocardiography may be useful in determining the intervention timing in these diseases. When the disease progresses in patients with pulmonary hypertension as a result of RV pressure overload, RV dilatation becomes more prominent than hypertrophy, and RV functional parameters predict the prognosis at this stage of maladaptive remodeling. The differential diagnosis of cardiomyopathy or comparison with nonpathological RV dilatation may be difficult in the setting of RV myocardial disease. The characteristics of RV functional parameters such as two-dimensional speckle tracking may help differentiate RV cardiomyopathy from other conditions. We review the diseases presenting with RV dilatation, their characteristics, and echocardiographic findings and parameters that are significant in assessing their status or intervention timing.
