Abstract Background and Aims Valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) has proven to be an effective treatment option for high-risk patients with degenerated surgical bioprosthetic valves. Multislice computed tomography (MSCT) analysis, the current gold standard procedural planning, certain limitations. Virtual reality (VR) could optimize preprocedural planning by delivering three-dimensional patient-specific information. This study aimed investigate feasibility of...
Due to the complex and variable anatomy of left atrial appendage, percutaneous appendage closure (LAAC) can be challenging. In this study, we investigated impact fusion imaging (FI) on LAAC learning curve two interventionalists. The first interventionalist (IC 1) was initially trained without FI continued his training with FI. second 2) performed all procedures We compared 36 IC 1 (group next interventions 2). Furthermore, group 2 who directly started 3). Group demonstrated that has a flat...
The complex and highly variable three-dimensional anatomy of the left atrial appendage (LAA) makes planning device sizing for interventional occlusion procedures (LAAC) challenging. Several imaging modalities [e.g. echocardiography, multi-slice computed tomography (MSCT)] are used this purpose. Virtual reality (VR) is an emerging technique to immerse into a atrium appendage, offering unprecedented options visualization measurement. This study aimed investigate feasibility, accuracy...
Background Understanding complex cardiac anatomy is essential for percutaneous left atrial appendage (LAA) closure. Conventional multi-slice computed tomography (MSCT) and transesophageal echocardiography (TEE) are now supported by advanced 3D printing virtual reality (VR) techniques three-dimensional visualization of volumetric data sets. This study aimed to investigate their added value LAA closure procedures. Methods Ten patients scheduled interventional were evaluated with MSCT TEE....
Detailed visualization and precise measurements of aortic valve dimensions are critical for the success transcatheter implantation prevention complications. Currently, multislice computed tomography is gold standard assessment annulus surrounding structures to determine prosthesis size. New technologies such as virtual reality (VR) not only enable 3-dimensional (3D) with potential improve understanding anatomy pathology but also allow in 3D. This study aims investigate feasibility, accuracy,...
Real-time echocardiography-fluoroscopy fusion imaging (FI) merges real-time echocardiographic with fluoroscopic images allowing intuitive anatomical spatial orientation during structural heart disease interventions. We aimed to assess the safety and efficacy of FI percutaneous left atrial appendage closure (LAAC).34 consecutive patients before (-FI) 121 after (+FI) introduction for LAAC were included in a single-centre study. In-hospital parameters analysed according adverse event (AE)...
Abstract Clinical Magnetic Resonance Imaging (MRI) of joints is limited to mere morphologic evaluation and fails directly visualize joint or ligament function. In this controlled laboratory study, we show that knee functionality may be quantified in situ as a function graded posterior cruciate (PCL)-deficiency by combining MRI standardized loading. 11 human underwent under loading the unloaded loaded (147 N) configurations intact, partially, completely PCL-injured conditions. For each...
Abstract Background Left atrial appendage closure (LAAC) is a safe and effective procedure for stroke prevention in patient with non-valvular fibrillation. Procedural planning device sizing remains challenging due to the highly complex variable three-dimensional (3D) anatomy of left (LAA). Virtual reality (VR) innovative, recent technology allowing superior spatial orientation visualization 3D imaging datasets. Purpose Therefore, we aimed evaluate feasibility accuracy LAA measurements VR...
Abstract Background High-quality imaging is integral throughout the transcatheter aortic valve implantation (TAVI) process, from patient selection and preprocedural planning to real-time guidance during procedure postprocedural follow-up. Multislice computed tomography (MSCT) currently gold standard. The next step in this area three-dimensional (3D) visualization of cardiac extra-cardiac structures using virtual reality (VR). Purpose This study aimed investigate feasibility, accuracy,...
Abstract Shock is a life-threatening condition. This study evaluated if sublingual microcirculatory perfusion on admission associated with 30-day mortality in older intensive care unit (ICU) shock patients. trial prospectively recruited ICU patients (≥ 80 years old) arterial lactate above 2 mmol/L, requiring vasopressors despite adequate fluid resuscitation, regardless of cause. All received sequential measurements (± 4 h) and 24 4) hours later. The primary endpoint was mortality. From...

Percutaneous left atrial appendage occlusion (LAAO) is an option to reduce the risk of stroke in patients with fibrillation and high bleeding risk. However, device-related thrombosis (DRT) post LAAO feared as complication. Simard et al. found a very incidence DRT compared other trials. antithrombotic regimen used devices have not been between studies.
