From an etiopathological perspective, tricuspid regurgitation can be classified in primary, due to the organic disease of any of the valve components, or secondary, as a result of tricuspid valve annulus dilatation, adverse right ventricular remodeling and tricuspid valve leaflet tethering. Despite its poor prognosis, most patients with tricuspid insufficiency are managed conservatively and only those with concomitant left heart valvular disease do finally go surgery in the real-world setting. In fact, outcomes of conventional surgery in patients with isolated tricuspid regurgitation are poor and this approach has not proven yet any survival benefit over stand-alone medical therapy. Given this unmet need, new transcatheter techniques have been developed in the last years, including leaflet plication, percutaneous annuloplasty and valve implantation in either the tricuspid position (orthotopic implantation) or in a different position such as the vena cava (heterotopic implantation). These techniques, with promising outcomes, are seen as an interesting alternative to open-heart surgery given the much lower periprocedural risk.","PeriodicalId":387779,"journal":{"name":"Interventional Cardiology [Working Title]","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116448046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lower bleeding rates in clinical randomized trials have translated into lower mortality prompting change in the guidelines. Advances in technique with use of ultrasound for access to properly size the sheath, proper dosing of anticoagulation and new techniques for sheath removal have dramatically lowered radial artery occlusion rates. Radial artery spasm has improved with vasodilators and proper sedation. Advances in support boards and sheath extension have opened up left radial access. Advances in lower profile sheaths and sheathless systems allow larger catheters in smaller arteries. Advances in longer balloons and sheaths have opened up radial access for peripheral interventions. Areas of clinical research include use of ulnar artery compared to radial, left versus right radial access, use of radial artery for a surgical conduit after angiography, radiation exposure and advantage of radial approach in the elderly.","PeriodicalId":387779,"journal":{"name":"Interventional Cardiology [Working Title]","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121295290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main contributors to the increased atherothrombotic risk in DM patients relates to their pro- inflammatory and prothrombotic status that involves abnormalities in endothelial and vascular smooth muscle cells, in platelet function and the coagulation cascade. The characteristics of CAD in diabetic patients is distinctive and infers an increased risk. Likewise, CAD in diabetics is characterised by being diffuse, affecting the left main stem more frequently, involving multiple vessels, and also affecting the distal coronary tree. Percutaneous coronary intervention in diabetics has been shown to have less favourable long-term clinical outcomes, compared to non-diabetics. With the advent of improved stent designs and antiplatelet drugs; the percutaneous coronary intervention (PCI) results have improved in the diabetic population. However, one of the main determinants of poorer outcomes in DM is the progression of atherosclerosis, which is more pronounced in diabetics and remains the primary cause of cardiac events at one year follow up after percutaneous revascularisation. Whilst new generation of drug-eluting stents has narrowed the gap between surgery and PCI in diabetic patients, coronary artery bypass grafting (CABG) remains the gold standard in diabetics with diffuse multivessel coronary artery disease.","PeriodicalId":387779,"journal":{"name":"Interventional Cardiology [Working Title]","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123998876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
