Abstract
Research performed in Europe has driven cardiovascular device innovation. This includes, but is not limited to, percutaneous coronary intervention, cardiac imaging, transcatheter heart valve implantation, and device therapy of cardiac arrhythmias and heart failure. An important part of future medical progress involves the evolution of medical technology and the ongoing development of artificial intelligence and machine learning. There is a need to foster an environment conducive to medical technology development and validation so that Europe can continue to play a major role in device innovation while providing high standards of safety. This paper summarizes viewpoints on the topic of device innovation in cardiovascular medicine at the European Society of Cardiology Cardiovascular Round Table, a strategic forum for high-level dialogue to discuss issues related to the future of cardiovascular health in Europe. Devices are developed and improved through an iterative process throughout their lifecycle. Early feasibility studies demonstrate proof of concept and help to optimize the design of a device. If successful, this should ideally be followed by randomized clinical trials comparing novel devices vs. accepted standards of care when available and the collection of post-market real-world evidence through registries. Unfortunately, standardized procedures for feasibility studies across various device categories have not yet been implemented in Europe. Cardiovascular imaging can be used to diagnose and characterize patients for interventions to improve procedural results and to monitor devices long term after implantation. Randomized clinical trials often use cardiac imaging-based inclusion criteria, while less frequently trials randomize patients to compare the diagnostic or prognostic value of different modalities. Applications using machine learning are increasingly important, but specific regulatory standards and pathways remain in development in both Europe and the USA. Standards are also needed for smart devices and digital technologies that support device-driven biomonitoring. Changes in device regulation introduced by the European Union aim to improve clinical evidence, transparency, and safety, but they may impact the speed of innovation, access, and availability. Device development programmes including dialogue on unmet needs and advice on study designs must be driven by a community of physicians, trialists, patients, regulators, payers, and industry to ensure that patients have access to innovative care.

Abstract
Introduction Atrial fibrillation (AF) presents a growing health concern, often requiring stroke prevention measures, primarily through oral anticoagulation (OAC). Surgical interventions such as left atrial appendage occlusion (LAAO) offer alternatives when OAC is contraindicated. In recent years, percutaneous procedures have gained traction as minimally invasive options, demanding precise anatomical insights. Fusion imaging (FI), which combines transesophageal echocardiography (TEE) and fluoroscopy, has emerged as a potential game-changer in transcatheter interventions. Aim This study introduces FI to LAAO procedures in Poland, assessing its role in guiding interventions, highlighting advantages, and exploring its potential to reshape cardiovascular interventions. Material and methods We conducted a retrospective study involving LAAO procedures from March 2015 to December 2018, all utilizing FI. Patient indications, procedural specifics, and safety metrics were collected and analyzed. Follow-ups were conducted at 3 and 6 months. Results A cohort of 83 patients (mean age: 72.1 ±8.4 years) underwent successful LAAO procedures. FI provided precise device placement and anatomical assessment. Mean procedure time was 54.9 ±34.3 min, contrast medium usage averaged 33.7 ±22.7 ml, and creatinine levels remained stable. Patients were discharged in about 4.2 ±3.4 days. Adverse effects were rare, including minimal bleeding and cardiac tamponade. Follow-ups demonstrated favorable outcomes with low adverse event rates. Conclusions This study marks the inaugural application of FI in Polish LAAO procedures. FI, offering enhanced visualization and reduced procedure times, holds promise in improving patient safety and treatment efficacy. We recommend its consideration as a standard visualization technique for LAAO procedures.

Abstract
Multi-modality cardiac imaging plays a key role in the management of patients with cardiovascular diseases. It allows a combination of complementary anatomical, morphological and functional information, increases diagnosis accuracy, and improves the efficacy of cardiovascular interventions and clinical outcomes. Fully-automated processing and quantitative analysis of multi-modality cardiac images could have a direct impact on clinical research and evidence-based patient management. However, these require overcoming significant challenges including inter-modality misalignment and finding optimal methods to integrate information from different modalities. This paper aims to provide a comprehensive review of multi-modality imaging in cardiology, the computing methods, the validation strategies, the related clinical workflows and future perspectives. For the computing methodologies, we have a favored focus on the three tasks, i.e., registration, fusion and segmentation, which generally involve multi-modality imaging data, either combining information from different modalities or transferring information across modalities. The review highlights that multi-modality cardiac imaging data has the potential of wide applicability in the clinic, such as trans-aortic valve implantation guidance, myocardial viability assessment, and catheter ablation therapy and its patient selection. Nevertheless, many challenges remain unsolved, such as missing modality, modality selection, combination of imaging and non-imaging data, and uniform analysis and representation of different modalities. There is also work to do in defining how the well-developed techniques fit in clinical workflows and how much additional and relevant information they introduce. These problems are likely to continue to be an active field of research and the questions to be answered in the future.

Abstract
OBJECTIVES The aim of this study was to determine whether the application of a CT-based preplanning algorithm might allow abstaining from TEE during LAAC. BACKGROUND LAAC is an established treatment alternative for patients with atrial fibrillation. Today, most LAAC procedures are guided by TEE, which, however, leads to the need for patient sedation and might even cause direct harm to the patient. CT-based preplanning of the LAAC procedure, in combination with technical improvements in device design and interventional experience, might allow abstaining from TEE. METHODS Fluoro-FLX is a prospective single-center study to evaluate how often TEE leads to a procedural change during interventional LAAC if a dedicated CT planning algorithm is applied. The study hypothesis is that under these circumstances, a sole fluoroscopy-guided LAAC is an alternative to a TEE-guided approach. All procedures are preplanned by cardiac CT and, finally, guided by fluoroscopy only, while TEE is carried out in the background during the intervention for safety reasons. RESULTS In none of the 31 consecutive patients did TEE lead to a change in the preplanned fluoroscopy-guided LAAC (success ratio: 1.00; CI: 0.94-1.00), thereby meeting the primary endpoint (performance goal: 0.90). There were no procedure-related adverse cardiac or cerebrovascular events (no pericardial effusion, TIA, stroke, systemic embolism, device embolism, death). CONCLUSIONS Our data suggest that it is feasible to perform LAAC under sole fluoroscopic guidance if preplanning is performed using cardiac CT. This might be worth considering, especially in patients who are at high risk for TEE-related adverse events.

Abstract
Although the left atrial appendage (LAA) seems useless, it has several critical functions that are not fully known yet, such as the causes for being the main origin of cardioembolic stroke. Difficulties arise due to the extreme range of LAA morphologic variability, making the definition of normality challenging and hampering the stratification of thrombotic risk. Furthermore, obtaining quantitative metrics of its anatomy and function from patient data is not straightforward. A multimodality imaging approach, using advanced computational tools for their analysis, allows a complete characterization of the LAA to individualize medical decisions related to left atrial thrombosis patients.

Abstract
In the wake of rapid advancement in cardiovascular procedural technologies, physician-led preprocedural planning utilizing multi-modality imaging training is increasingly recognized as invaluable for procedural accuracy. Left atrial appendage occlusion (LAAO) is one such procedure in which complications such as device leak, cardiac injury, and device embolization can be decreased substantially with incorporation of physician driven imaging and digital tools. We discuss the benefits of cardiac CT and 3D printing in preprocedural planning for the Heart Team, as well as novel applications by physicians of intraprocedural 3D angiography and dynamic fusion imaging. Furthermore, incorporation of computational modeling and artificial intelligence (AI) may yield promise. For optimal patient-centric procedural success, we advocate for standardized preprocedural imaging planning by physicians within the Heart Team as an essential part of LAAO.

Abstract
INTRODUCTION Interventional closure of the left atrial appendage (LAAC) has been established as an alternative treatment for patients with atrial fibrillation (AF) and an elevated risk of stroke. The WATCHMAN FLX (WM FLX) as the newest WATCHMAN LAAC device differs in several technical characteristics from its precursor, the WATCHMAN V.2.5 (WM V.2.5). METHODS The data presented here are derived from a retrospective single-centre study. All patients in which an LAAC was performed between February 2017 and March 2021 with either a WM V.2.5 or WM FLX device were included. RESULTS 169 patients were included in this study, of whom 95 had been treated with WM V.2.5 and 74 with WM FLX, respectively. Directly after implantation, only minor differences regarding membrane thickness and connector protrusion were noted, whereas no relevant differences were found regarding device sizing, device compression or peridevice leakage, respectively. However, at 3-month follow-up, device compression was significantly reduced in WM FLX indicating a continued device expansion which was paralleled by a reduced number of peridevice leakage in comparison to WM V.2.5. Additionally, the combined clinical endpoint of death, stroke/transistoric ischaemic attack, tamponade, device embolisation, device-related thrombosis or peridevice leakage was reduced in WM FLX. CONCLUSION LAAC using the WM FLX device results in a continued device expansion over the first 3 months based on differences in radial force in comparison to WM V.2.5. This is accompanied by a reduction in adverse clinical endpoints.

Abstract
AIMS The aim of this study was to determine the incidence of transoesophageal echocardiography (TOE)-related adverse events (AEs) during structural heart disease (SHD) interventions and to identify potential risk factors. METHODS AND RESULTS We retrospectively analysed 898 consecutive patients undergoing TOE-guided SHD interventions under procedural sedation. TOE-related AEs were classified as bleeding complications, mechanical lesions, conversion to general anaesthesia with intubation, and the occurrence of pneumonia. A follow-up was conducted up to 3 months after the intervention. TOE-related AEs were observed in 5.3% of the patients (n = 48). The highest rate of AEs was observed in the percutaneous mitral valve repair (PMVR) group with 8.2% (n = 32), whereas 4.8% (n = 11) of the patients in the left atrial appendage group and 1.8% (n = 5) in the patent foramen ovale/atrial septal defect group developed a TOE-related AE (P = 0.001). The most frequent AE was pneumonia with an incidence of 2.6% (n = 26) in the total cohort. Bleeding events occurred in 1.8% (n = 16) of the patients, mostly in the PMVR group with 2.1% (n = 8). In the multivariate regression analysis, we found a lower haemoglobin {odds ratio (OR) [95% confidence interval (CI)]: 8.82 (0.68-0.98) P = 0.025} and an obstructive sleep apnoea syndrome (OSAS) [OR (95% CI): 2.51 (1.08-5.84) P = 0.033] to be associated with AE. Furthermore, AEs were related to procedural time [OR (95% CI): 1.01 (1.0-1.01) P = 0.056] and oral anticoagulation [OR (95% CI): 1.97 (0.9-4.3) P = 0.076] with borderline significance in the multivariate regression analysis. No persistent damages were observed. CONCLUSION TOE-related AEs during SHD interventions are clinically relevant. It was highest in patients undergoing PMVR. A lower baseline haemoglobin level and an OSAS were found to be associated with the occurrence of a TOE-related AE.

Abstract
BACKGROUND AND AIM The objective of this study was to understand the clinical efficacy and application of the percutaneous left atrial appendage occlusion (PLAAO) guided only by the transesophageal echocardiography (TEE) in patients with nonvalvular atrial fibrillation (NVAF), without using the fluoroscopy and angiography. METHODS During the time period of this study from June 2020 to June 2021, 32 patients underwent PLAAO and all underwent a TEE guided approach. The anatomical features of the left atrial appendage (LAA) were evaluated and observed by TEE before and during the procedure. LAA occluder device was selected for the appropriate size. Intraoperative TEE guided and monitored the process of PLAAO in real-time, and also evaluated the stability and tightness of the occluder device, following monitored postoperative complications. RESULTS The PLAAO procedure was successful in all the patients. No serious complications like dislocation of the occluder and embolism were seen. Postoperative TEE demonstrated that the PLAAO occluder devices were in a good position without residual shunting. CONCLUSIONS PLAAO only guided by TEE may become a safe and reliable surgical procedure, which can protect surgeons and patients from radiation, and can gradually become a novel surgical method of PLAAO with the practical application value.

Abstract
BACKGROUND Real-time echocardiography-fluoroscopy fusion imaging (FI) merges real-time echocardiographic imaging with fluoroscopic images allowing intuitive anatomical spatial orientation during structural heart disease interventions. We aimed to assess the safety and efficacy of FI during percutaneous left atrial appendage closure (LAAC). METHODS 34 consecutive patients before (-FI) and 121 patients after (+FI) the introduction of FI for LAAC were included in a single-centre study. In-hospital safety parameters were analysed according to adverse event (AE) definition of the Munich consensus document and procedure-related parameters were assessed for efficacy. An ANCOVA was performed to investigate the influence of a learning curve. RESULTS Time until successful transseptal puncture was significantly reduced as well as total procedure time and the amount of contrast agent used (+FI/-FI:17 ± 6.35 min vs. 22 ± 8.33 min, p = 0.001; +FI/-FI: 50 min IQR 43 min - 60 min vs. 57 min IQR 45 min -70 min; p = 0.013; +FI/-FI: 70 mL, IQR 55 ml-90 mL vs. 152 mL, IQR 107 mL - 205 mL; p < 0.001). However, fluoroscopy time and dose-area product did not differ between both groups. There was no significant difference in the occurrence of in-hospital adverse events (+FI/-FI: 2.5% vs. 0%; p = 0.596). The ANCOVA revealed that the learning curve does not affect procedural efficacy parameters such as procedure time, time to transseptal puncture, amount of contrast agent and dose-area product. CONCLUSIONS FI for LAAC reduces the total procedure time, the time to successful transseptal puncture and periprocedural amount of contrast agent.
