This will be achieved through automated analyses of pre-interventional computed tomography (CT) scans.\n\nSevere tricuspid regurgitation is associated with poor patient outcomes. In advanced stages, pharmacological therapy becomes ineffective, and surgical intervention carries a high mortality risk. Given this clinical challenge, catheter-based treatment of the tricuspid valve has become a focal point of research.\n\nOne well-established treatment strategy is percutaneous tricuspid valve intervention, which aims to reduce regurgitation either through annuloplasty, leaflet-based edge-to-edge repair or valve replacement. This approach has been shown to significantly decrease the severity of regurgitation, leading to a dramatic reduction in symptom burden and a marked improvement in quality of life.\n\nHowever, predicting which patients will benefit most from TTVI and determining the optimal technique for each individual remain largely unresolved challenges.\n\nArtificial intelligence (AI)-powered software, such as heart.ai by LARALAB (Munich), enables automated measurement of anatomical structures captured via CT imaging. This technology already allows for rapid and precise assessment of cardiac chambers and the tricuspid annulus throughout the entire cardiac cycle, facilitating a comprehensive three-dimensional evaluation of right heart anatomy.\n\nTo refine patient selection and optimize procedural strategies for TR treatment, the researcher work a multi-center collaboration to analyze treatment outcomes and patient response to specific therapeutic approaches.",[299,24],"Tricuspid Regurgitation",[301,302,303,304,305],"transcatheter tricuspid valve intervention","TTVI","TR","MSCT","Tricuspid regurgitation","2025-04-22",{"date":308,"type":29},"2025-04-30",{"date":310,"type":29},"2023-07-19",{"date":312,"type":20},"2030-06-01",{"name":314,"class":62},"Heart and Diabetes Center North-Rhine Westfalia",{"id":316,"slug":317,"hasResults":11,"nctId":318,"briefTitle":319,"officialTitle":320,"acronym":321,"eligibilityCriteria":322,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":272,"enrollmentInfo":323,"targetDuration":325,"studyType":21,"phases":4,"briefSummary":326,"conditions":327,"keywords":332,"overallStatus":112,"whyStopped":4,"lastUpdateSubmitDate":339,"lastUpdatePostDateStruct":340,"startDateStruct":342,"completionDateStruct":344,"leadSponsor":346,"locationsCount":4},"100576961","ga-68-dolacga-pet-scan-in-hcc-under-rfa-100576961","NCT06792097","Ga-68 Dolacga PET Scan in HCC Under RFA","The Role of Ga-68 Dolacga PET Scan in Patients With Hepatocellular Carcinoma Under Radiofrequency Ablation","HCC; RFA","Inclusion Criteria:\n\n* Patients with hepatocellular carcinoma (BCLC stage 0 and stage A) eligible for radiofrequency ablation (RFA) treatment exhibit the following characteristics:\n\n  1.
