The acute success rate for different types of AT ranged from 75 to 97% using Rhythmia, while the NavX mapping system was also found to have excellent efficacy in the setting of AT, with acute arrhythmia termination rates ranging from 73 to 99%. With regard to ventricular tachycardia, in the setting of ischaemic cardiomyopathy, acute success rates ranged from 70 to 100% using CARTO and 64% using EnSite/NavX systems. The acute success rate using the Rhythmia system ranged from 61.5 to 100.0% for different clinical settings. <b>Conclusions:</b> Mapping systems have played a crucial role in high-density mapping and the observed high procedural success rates of atrial and ventricular CA procedures.

Increased understanding of the underlying pathogenesis responsible for the misfolding of transthyretin and the subsequent accumulation of amyloid fibrils within the myocardium has led to the development of several disease-modifying therapies that act on different stages of the disease pathway. Tafamidis is the first, and to date remains the only, therapy approved for the treatment of ATTR-CA, which, alongside acoramidis, stabilizes the transthyretin tetramer, preventing disaggregation, misfolding and formation of amyloid fibrils. Gene-silencing agents, such as patisiran, vutrisian and eplontersen, and novel gene-editing therapies, such as NTLA-2001, act to reduce the hepatic synthesis of transthyretin. Anti-amyloid therapies represent another strategy in the treatment of ATTR-CA and are designed to bind amyloid fibril epitopes and stimulate macrophage-mediated removal of amyloid fibrils from the myocardium. Many of these treatments are at an early investigational stage but represent an important area of unmet clinical need and could potentially reverse disease and restore cardiac functions even in patients with advanced disease.</p>","PeriodicalId":12836,"journal":{"name":"Heart International","volume":"18 1","pages":"30-37"},"PeriodicalIF":1.9,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11239131/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141616284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review focuses on the Navitor™ valve, a third-generation intra-annular Portico™ valve (Abbott Structural Heart, St Paul, MN, USA) designed to address TAVR complications, particularly paravalvular leak (PVL). We present an overview of the Navitor™ system, comparing it to the first-generation Portico™ THV in terms of THV design, key iterations and clinical outcomes. The Navitor™ THV introduces two key refinements-a protective outer sealing skirt and a more flexible delivery system. These enhancements have led to a significant reduction in 30 day PVL rates, from 6.3% with the first-generation Portico™ to 0% with the Navitor™ system. Additionally, the Navitor™ system exhibited lower rates of severe bleeding (27.3% versus 13.1%) and major vascular complications (5.8% versus 0.7%) compared with the first-generation Portico™. The Navitor™ valve represents a promising advancement in TAVR technology, with notable reductions in complications such as PVL, severe bleeding, and major vascular issues, compared with its predecessor. While further research is needed to assess long-term durability, these results underscore its potential benefits in enhancing patient outcomes and reducing complications.

However, the relationship between CAC and quantitative calcified plaque volume (CPV), which is measured on coronary computed tomography angiography (CCTA), is not well understood. Furthermore, there is limited evidence evaluating the difference between CAC versus CPV and CAC versus total plaque volume (TPV) in predicting obstructive coronary artery disease (CAD). <b>Methods:</b> This study included 147 subjects from the CLARIFY registry, a multicentered study of patients undergoing assessment using CCTA and CAC score as part of acute and stable chest pain evaluation. Automated software service (Cleerly.Inc, Denver, CO, USA) was used to evaluate the degree of vessel stenosis and plaque quantification on CCTA. CAC was measured using the standard Agatston method.
