Abstract Objectives The aim of this study was to assess the value of echocardiographic right ventricular (RV) and systolic pulmonary artery pressure (sPAP) assessment in predicting transcatheter tricuspid edge-to-edge valve repair (TTVR) outcome. Background RV dysfunction and pulmonary hypertension are associated with poor prognosis and are systematically sought during tricuspid regurgitation evaluation. The value of echocardiographic assessment in predicting TTVR outcome is unknown. Methods Dat...

Background and Aims: Tricuspid regurgitation (TR) is a frequent valvular heart disease with relevant adverse impact on patients' prognosis. Adequate TR imaging and evaluation is challenging. In this study, we aimed to compare different imaging modalities (echocardiography and multi-slice computed tomography) for the assessment of tricuspid valve (TV) function and geometry. Methods: We retrospectively investigated patients that presented to University Hospital Bonn, Germany, between September 201...

BACKGROUND: Data on thrombus resolution and clinical outcome data after a therapy of LAA thrombus with novel oral anticoagulants (NOACs) are scarce. METHODS: In this single-center study, we retrospectively analyzed 78 patients diagnosed with a solid LAA thrombus by transesophageal echocardiography (TEE). We assessed baseline clinical and echocardiographic characteristics, the anticoagulatory regimens and outcomes of patients with (responders) and without (non-responders) thrombus resolution. RES...

Adaptive immune responses regulate the development of atherosclerosis, with a detrimental effect of type 1 but a protective role of type 2 immune responses. Immunization of Apolipoprotein E-deficient (ApoE(-/-) ) mice with Freund's adjuvant inhibits the development of atherosclerosis. However, the underlying mechanisms are not fully understood. Thymic stromal lymphopoietin (TSLP) is an IL7-like cytokine with essential impact on type 2 immune responses (Th2). Thymic stromal lymphopoietin is stron...

OBJECTIVES: The purpose of this study was to investigate the impact of periprocedural troponin levels on clinical outcome following the MitraClip procedure. BACKGROUND: Cardiac troponin is known to be a predictive biomarker for various clinical outcomes; however, data about its predictive value in patients undergoing transcatheter mitral valve repair are limited. METHODS: Consecutive patients undergoing the MitraClip procedure were enrolled. Serum cardiac troponin I concentrations were measured ...

Abstract Objectives The aim of this study was to determine the safety and efficacy of chimney stenting, a bailout technique to treat coronary artery occlusion (CAO). Background CAO during transcatheter aortic valve replacement (TAVR) is a rare but often fatal complication. Methods In the international Chimney Registry, patient and procedural characteristics and data on outcomes are retrospectively collected from patients who underwent chimney stenting during TAVR. Results To date, 16 centers hav...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative treatment option to surgical aortic valve replacement (SAVR) in selected high-risk patients. In this study, we aimed to evaluate the prognostic value of right ventricular (RV) functional imaging to predict clinical response to TAVR and SAVR. METHODS: One hundred and ten patients with symptomatic severe aortic valve stenosis (AVS) undergoing successful TAVR and 32 controls undergoing SAVR were prospectively enrolled. Six ...
