Alerts clinicians to evolving percutaneous options; leaves open rigorous outcome data for newer applications.
Over the past few years we have witnessed an impressive increase in the number of percutaneous cardiac procedures, in parallel with the development of new technology. Drug-impregnated stents implanted in the coronary circulation promise significant decreases in restenosis rates. Covered endovascular stent-grafts are being used successfully to treat descending thoracic aortic aneurysms and dissections, significantly lessening the morbidity and mortality of surgical intervention, and ongoing trials are evaluating the safety and efficacy of percutaneous device closure of atrial septal defects.
