Cardiologists receive instruction in peripheral vascular disorders during fellowship training, and this includes training in the performance of noncardiac angiography. Interventional cardiologists possess the technical skills to perform peripheral vascular interventions and the clinical skills to care for patients who undergo these interventions, but they generally lack the fund of knowledge needed to provide comprehensive care. Newly revised criteria for the certification of cardiologists in peripheral vascular intervention were recently published by the Society of Cardiac Angiography and Intervention. A novel element of these revised guidelines is a tiered approach that includes limited certification for renal and iliac intervention, or unrestricted certification for physicians who meet more rigid criteria. The limited certification criteria are designed to facilitate entry into the field by practicing cardiologists who wish to expand their clinical skills for the benefit of patients with peripheral vascular disease.</p>","PeriodicalId":80270,"journal":{"name":"Current interventional cardiology reports","volume":"1 4","pages":"298-302"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21921636","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}

An imbalance between oxygen demand and supply (ischemia), as occurs when coronary arteries become obstructed by atherosclerotic plaques, triggers a response to improve myocardial perfusion by the formation of new capillaries (angiogenesis) and by the enlargement of preexisting collateral vessels (arteriogenesis). Recently, novel insights have been obtained in the molecular mechanisms of angiogenesis and in its control by hypoxia. This has lead to the design of strategies to improve myocardial perfusion. However, rational design of therapeutic angiogenesis mandates a better understanding of the molecular basis of angiogenesis. This review discusses the role of two prime classes of angiogenic molecules, namely of vascular endothelial growth factor (VEGF) and angiopoietin (Ang), and addresses novel insights in the regulation of angiogenesis by hypoxia. In addition, a novel mouse model of ischemic cardiomyopathy with signs of hibernation is presented. Possible implications for therapeutic myocardial angiogenesis are discussed.</p>","PeriodicalId":80270,"journal":{"name":"Current interventional cardiology reports","volume":"1 4","pages":"322-335"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21921639","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}

Although still experimental in the United States, this operation has become routine in several centers in Australia and Europe. Collective experience with endovascular repair has yielded complication and mortality results that compare favorably with those from leading studies of conventional repair, despite significant medical comorbidity among its cohorts.

Although most preclinical studies have employed methods of prolonged drug delivery and local therapy, the need for repeated administration and invasive access has limited the clinical usefulness of these delivery strategies. Intracoronary and intravenous delivery, with their potential widespread applicability, has fueled their use in most clinical trials of therapeutic angiogenesis; however, the significant systemic recirculation, limited myocardial retention, and potential for serious systemic adverse events are major limitations to their clinical use. Epicardial delivery using surgical access has been used in several clinical studies, but the need for surgical access and general anesthesia may limit the usefulness of this technique. The development of percutaneous endocardial delivery catheters using fluoroscopic guidance or Biosense NOGA (Biosense Laboratories, Haifa, Israel) electromagnetic three- dimensional navigation system has generated significant interest in the use of this delivery strategy in therapeutic myocardial angiogenesis studies.

Notwithstanding, results of pilot and randomized trials show a surprisingly low incidence of (sub)acute stent thrombosis under challenging circumstances, such as acute coronary syndromes. Considering the quite low incidence of early complications with noncoated second-generation stents, it may require large trials to prove the clinical efficacy of the heparin- coating against noncoated devices. However, even if the \"added value\" of the heparin-coating will never be clinically proven, it has helped to enhance the penetration of stent therapy in interventional cardiology. Unlike the situation in 1992, very few cardiologists will now disagree with the statement that stents contribute to the state-of-the-art treatment of patients with angina pectoris or acute myocardial infarction.
