Echocardiography is an excellent noninvasive imaging modality for evaluation and follow-up of cardiac lesions, especially coronary artery changes occurring as a result of Kawasaki disease. The information obtained has prognostic implications and can be complemented with other modes of imaging for risk stratification and optimization of both medical and interventional therapy. The aim of this article is to describe the time line of echocardiographic follow-up of patients affected with Kawasaki disease. The classification of coronary artery changes and transthoracic echocardiographic views recommended for detailed evaluation of the coronary arteries are delineated in detail in this report...

Physical exercise is commonly regarded as protective against cardiovascular disease (CVD). Recent studies have reported that exercise alters the gut microbiota and that modification of the gut microbiota can influence cardiac function. Here, we focused on the relationships among exercise, the gut microbiota and cardiac function after myocardial infarction (MI). Four-week-old C57BL/6J mice were exercised on a treadmill for 4 weeks before undergoing left coronary artery ligation. Cardiac function was assessed using echocardiography...

BACKGROUND: Type 2 congenital generalized lipodystrophy (CGL2, OMIM 269700) is a rare autosomal recessive disease, characterized by the generalized absence of adipose tissue at birth or in early infancy. Pathogenic variants in BSCL2 gene have been reported to be responsible for CGL2. The aim of this study is to analyze the clinical and genetic characteristics of two Chinese patients with CGL2, and with particular focus on the BSCL2 gene sequence variants. METHODS: Medical history, clinical manifestations, physical examination, laboratory data, and ultrasonography findings were analyzed for the two patients with CGL2...

Cardiovascular diseases (CVD) represent the leading cause of maternal mortality and morbidity. Knowledge of CVD in women is constantly evolving and data are emerging that female-specific risk factors as complications of pregnancy are conditions associated with an increased risk for the long-term development of CVD. Echocardiography is a safe and effective imaging technique indicated in symptomatic or asymptomatic pregnant women with congenital heart diseases who require close monitoring of cardiac function...

The pathophysiology and the management of patients with acute right heart failure are very complex. The bed-side focused echocardiography is the basis of differential diagnosis and acute diagnosis. Individual therapy monitoring is complex due to the strong preload dependence of the right ventricle and the limitation of non-invasive estimation of pulmonary-vascular hemodynamics, so that the indication for a pulmonary artery catheter should be liberal in acute right heart failure. The treatment goals of acute right heart failure are the treatment of the underlying disease or triggering factors in combination with individualized optimization of hemodynamic tailored to current right-ventricular function...

BACKGROUND: The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure...

BACKGROUND: Traditional cardiovascular risk stratification tools that employ clinical risk factors are limited by their modest discriminative abilities. As such, robust cardiovascular risk assessment, including our understanding of the complex interplay between risk factors, in the primary preventive setting, remains incomplete. Phenotypical heterogeneity may be even greater among subjects with hyperglycemic conditions, i.e., prediabetes and diabetes, which is worrisome, given the dramatic global rise in mean fasting glucose levels, and the strong association with adverse cardiovascular outcomes...

Coronary artery disease (CAD) continues to be a leading cause of morbidity and mortality worldwide. Although invasive coronary angiography has previously been the gold standard in establishing the diagnosis of CAD, there is a growing shift to more appropriately use the cardiac catheterization laboratory to perform interventional procedures once a diagnosis of CAD has been established by noninvasive imaging modalities rather than using it primarily as a diagnostic facility to confirm or refute CAD. With ongoing technological advancements, noninvasive imaging plays a pre-eminent role in not only diagnosing CAD but also informing the choice of appropriate therapies, establishing prognosis, all while containing costs and providing value-based care...

PURPOSE OF REVIEW: The purpose of the present paper is to analytically review the diagnostic and prognostic role of CMR in ST-segment elevation myocardial infarction (STEMI) survivors. Percutaneous coronary intervention (PCI) is the treatment of choice in patients STEMI. However, risk of future events remains substantial. Assessment of the extent of myocardial infarction (MI), cardiac function and ventricular remodelling has become the focus of recent studies. Electrocardiography, angiography and echocardiography parameters, as well as risk scores, lack sensitivity and reproducibility in predicting future cardiovascular events...

Sudden cardiac death (SCD) is a devastating event in athletes. Screening efforts that were first directed at athletes younger than 35 years, are now focusing on the rapidly growing group of older sportspersons. Athletes aged ≥35 years have a 10-fold increased risk of exercise-related cardiac arrest, mostly due to coronary artery disease (CAD). Although cardiac imaging is pivotal in identifying CAD, the role of imaging modalities in screening asymptomatic older sportspersons remains unclear. We performed a scoping review to identify the role of cardiac imaging to detect CAD in older sportspersons and to identify gaps in the existing literature...

A 28-year-old man was admitted to our emergency service with a shortness of breath and palpitation. On admission, his blood pressure was high and he was in hypertensive pulmonary edema. His physical examination showed rales in both lungs and pansystolic murmur at mitral focus. His medical history included aortic valve replacement (AVR) because of native aortic valve infective endocarditis. Transthoracic echocardiography (TTE) showed normal functional aortic valve. Color flow imaging demonstrated severe mitral regurgitation with posterior eccentric jet...

Acute respiratory distress syndrome (ARDS) is burdened with significant mortality, mainly in connection with circulatory failure. The right ventricle (RV) is the weak link of hemodynamic stability among ARDS patients and its failure, also named "severe" acute cor pulmonale (ACP), is responsible for excess mortality. Driving pressure ≥18 cmH2O, PaCO2 ≥48 mmHg and PaO2/FiO2 <150 mmHg are three preventable factors recently identified as independently associated with ACP, on which ventilator strategy designed to protect the RV has to focus...

Transthoracic echocardiography has become increasingly popular in clinical practice. It is used for the functional evaluation of patients with various cardiovascular diseases. Its use has been extended further in routine screening for cardiovascular health and in preoperative risk assessment before non-cardiac surgery because it is non-invasive, easy to perform, reproducible, and cost-effective. When the results of preoperative echocardiography contain abnormalities, the findings must be interpreted to determine clinical relevance...

Current research on valvular heart repair has focused on tissue-engineered heart valves (TEHV) because of its potential to grow similarly to native heart valves. Decellularized xenografts are a promising solution; however, host recellularization remains challenging. In this study, decellularized porcine aortic valves were implanted into the right ventricular outflow tract (RVOT) of sheep to investigate recellularization potential. Porcine aortic valves, decellularized with sodium dodecyl sulfate (SDS), were sterilized by supercritical carbon dioxide (scCO2) and implanted into the RVOT of five juvenile polypay sheep for 5 months (n = 5)...

OBJECTIVE: Focused transthoracic echocardiography (FTTE) is an emerging tool in the management of critically ill patients, but the lack of adequate training models has limited the expansion of this technology. Although basic FTTE training courses have been shown to be sufficient in developing echocardiography skills, limited data exist regarding skill retention. In an effort to develop an adequate FTTE training model, we sought to determine the degree of skill retention after FTTE training...
