Echocardiographic assessment of left atrial appendage morphology and function-an expert proposal by the German Working Group of Cardiovascular Ultrasound.

The left atrial appendage is a blind ending cardiac structure prone to blood stasis due to its morphology. This structure is a preferred region of thrombogenesis in relation to reduced myocardial contractility of the atrial wall. Blood stasis occurs primarily in low flow conditions.

Echocardiographic assessment of atrial, ventricular, and valvular function in patients with atrial fibrillation-an expert proposal by the german working group of cardiovascular ultrasound.

Echocardiography in patients with atrial fibrillation is challenging due to the varying heart rate. Thus, the topic of this expert proposal focuses on an obvious gap in the current recommendations about diagnosis and treatment of atrial fibrillation (AF)-the peculiarities and difficulties of echocardiographic imaging. The assessment of systolic and diastolic function-especially in combination with valvular heart diseases-by echocardiography can basically be done by averaging the results of echocardiographic measurements of the respective parameters or by the index beat approach, which uses a representative cardiac cycle for measurement.

Prognostic Value of Galectin-3 after Left Atrial Appendage Occlusion for Predicting Peri-Device Leakage.

Echocardiographic detection of residual peri-device leakage (PDL) after percutaneous left atrial appendage occlusion (LAAO) is crucial for managing anticoagulation. Galectin-3, a protein involved in tissue-foreign body interactions, may hold significance in understanding PDL and cardiac tissue remodeling after LAAO. This study aimed to analyze galectin-3 serum levels in relation to PDL using a novel echo-morphological classification.

Closure of a Patent Foramen Ovale (PFO): An Intervention Sequence.

A patent foramen ovale (PFO) persists in about one-quarter of people and is the source of up to 25% of all ischemic strokes, especially strokes in young adults. PFO can be easily diagnosed by transthoracic contrast and/or transesophageal echocardiography. Interventional closure of the PFO via the femoral vein is a commonly used cardiological procedure since several trials have demonstrated the superiority of PFO closure over standard medical therapy in patients with PFO and who have experienced post ischemic, cardioembolic, or cryptogenic stroke.

Metabolomic Profiling in Patients with Heart Failure and Exercise Intolerance: Kynurenine as a Potential Biomarker.

Aims: Metabolic and structural perturbations in skeletal muscle have been found in patients with heart failure (HF) both with preserved (HFpEF) and reduced (HFrEF) ejection fraction in association with reduced muscle endurance (RME). We aimed in the current study to create phenotypes for patients with RME and HFpEF compared to RME HFrEF according to their metabolomic profiles and to test the potential of Kynurenine (Kyn) as a marker for RME. Methods: Altogether, 18 HFrEF, 17 HFpEF, and 20 healthy controls (HC) were prospectively included in the current study.

A Novel Echocardiographic-Based Classification for the Prediction of Peri-Device Leakage following Left Atrial Appendage Occluder Implantation.

(1) Background: The assessment of residual peri-device leakages (PDL) after left atrial appendage occlusion (LAAO) remains crucial for post-procedural management. Our study aimed to verify a novel echocardiographic classification for the prediction of PDL. (2) Methods: Echocardiographic data of 72 patients who underwent percutaneous LAAO were evaluated.

Predictors of worsening TR severity after right ventricular lead placement: any added value by post-procedural fluoroscopy versus three -dimensional echocardiography?

Background: The effect of right ventricular (RV) leads on tricuspid valve has been already raised concerns, especially in terms of prognostic implication. For such assessment, three-dimensional transthoracic echocardiography (3D-TTE) has been used previously but there was no data on the use of post-procedural fluoroscopy in the literature.

Methods: We prospectively enrolled 59 patients who underwent clinically indicated placement of pacemaker or implantable cardioverter defibrillator (ICD).

Relation of left atrial function with exercise capacity and muscle endurance in patients with heart failure.

Aims: Both left atrial strain (LAS) and skeletal muscle endurance demonstrate a linear relationship to peak VO . Less is known about the relationship between central (cardiac) and peripheral (muscle endurance) limitations of exercise capacity in patients with heart failure (HF). We investigated this relationship using novel cardiac markers such as LAS and left atrial emptying fraction (LAEF).

Patent foramen ovale-When to close and how?

Closure of a patent foramen ovale (PFO) in patients after cryptogenic/cardioembolic stroke is recommended by current guidelines for patients who are 16-60 years of age with a high-risk PFO (class of recommendation A, level of evidence I). The use of double-disk occlusion devices followed by antiplatelet therapy is recommended. The procedure of interventional PFO closure compared with other interventions in cardiology is rather easy to learn.

Psychosocial factors, mental health, and coordination capacity in patients with heart failure with preserved ejection fraction compared with heart failure with reduced ejection fraction.

Aims: Patients with heart failure (HF) suffer from reduced quality-of-life (QoL). We aimed to compare QoL, depression, and anxiety scores among outpatients with preserved (HFpEF) and reduced (HFrEF) ejection fraction and non-HF controls and its relationship to coordination capacity.

Methods And Results: Fifty-five participants were recruited prospectively at the University Hospital Jena, Germany (17 HFpEF, 18 HFrEF, and 20 non-HF controls).

Skeletal Muscle Function, Structure, and Metabolism in Patients With Heart Failure With Reduced Ejection Fraction and Heart Failure With Preserved Ejection Fraction.

Background: Reduced exercise capacity in patients with heart failure (HF) could be partially explained by skeletal muscle dysfunction. We compared skeletal muscle function, structure, and metabolism among clinically stable outpatients with HF with preserved ejection fraction, HF with reduced ejection fraction, and healthy controls (HC). Furthermore, the molecular, metabolic, and clinical profile of patients with reduced muscle endurance was described.

Improvement in Left Atrial Strain among Patients Undergoing Percutaneous Left Atrial Appendage Closure.

Background: Various clinical trials provide evidence about the safety, effectiveness, and therapeutic success of percutaneous left atrial appendage closure (LAAC) using various occlusion devices. These devices are foreign materials implanted into the left atrium and may deteriorate left atrial (LA) function. The aim of this study was to evaluate the change in transesophageal echocardiography (TEE)-derived LA strain after LAAC.

The pivotal role of cardiovascular imaging in the identification and risk stratification of non-compaction cardiomyopathy patients.

Non-compaction cardiomyopathy (NCM) is a heterogeneous myocardial disease that can finally lead to heart failure, arrhythmias, and/or embolic events. Therefore, early diagnosis and treatment is of paramount importance. Furthermore, genetic assessment and counseling are crucial for individual risk assessment and family planning.

Aortic annulus measurement with computed tomography angiography reduces aortic regurgitation after transfemoral aortic valve replacement compared to 3-D echocardiography: a single-centre experience.

Background: Accurate assessment of the aortic annulus is crucial for successful transcatheter aortic valve replacement (TAVR), in particular to prevent paravalvular regurgitation (PVR). We compared aortic annular sizing using multidetector computed tomography (MDCT) and three-dimensional transoesophageal echocardiography (3-D TEE) to determine the predictive value of MDCT.

Methods And Results: All patients admitted for transfemoral TAVR [n = 227; 48.

Metastatic obliterating mass of right ventricular cavity: A report of case and echocardiographic features.

We present the case of a 63-year-old man with a history of non-small cell lung carcinoma (NSCLC) and systemic chemotherapy who suffered from progressive shortness of breath and peripheral edema. Transthoracic echocardiography showed a huge non-homogenous mass nearly completely filling the dilated right ventricle. The border of mass was not differentiable from the right ventricular myocardium.

Quantification of mitral regurgitation during percutaneous mitral valve repair: added value of simultaneous hemodynamic and 3D echocardiographic assessment.

The objective of this study was to investigate the usefulness of intraprocedural hemodynamic monitoring for MR evaluation during pMRV. Assessment of mitral regurgitation (MR) during percutaneous mitral valve repair (pMVR) procedure is challenging. 3D color Doppler allows exact quantification of MR, but is technically demanding.

Vena contracta area for severity grading in functional and degenerative mitral regurgitation: a transoesophageal 3D colour Doppler analysis in 500 patients.

Aims: Vena contracta area (VCA3D), derived by 3D colour Doppler echocardiography, has already been validated against cardiac magnetic resonance imaging, but the number of clinical studies to define cut-off values for grading of mitral regurgitation (MR) is limited. Aim of the study was to assess VCA3D in a large population of patients with functional (FMR) and degenerative MR (DMR).

Methods And Results: Transoesophageal echocardiography was performed in 500 patients with MR.

Interventional left atrial appendage occlusion: added value of 3D transesophageal echocardiography for device sizing.

Aim of this study was the assessment of left atrial appendage (LAA) dimensions comparing 2D- to 3D-TEE measurements in patients with nonvalvular atrial fibrillation undergoing percutaneous LAA occlusion. Patients underwent transesophageal echocardiography (TEE) before, during and 45 days after intervention. The maximal LAA orifice diameters in 2D-TEE (LODmax 2D) were obtained from multiple views.

Optimal prosthesis sizing in transcatheter aortic valve implantation by exclusive use of three-dimensional transoesophageal echocardiography.

Purpose: The assessment of aortic annular size is critical, and inappropriate sizing is thought to be a main reason of paravalvular aortic regurgitation. Multidetector computed tomograph is associated with the risk of contrast nephropathy. For optimal evaluation of the complex structure of the aortic annulus, three-dimensional (3D)-methods should be used.
