OBJECTIVES We compared the angiographic and long-term clinical outcomes of patients with and without overlap of drug-eluting stents (DES). BACKGROUND DES overlap has been associated with delayed healing and increased inflammation in experimental studies, but its impact on clinical outcome is not well established. METHODS We analyzed the angiographic and clinical outcomes of 1,012 patients t...
BACKGROUND Sirolimus-eluting stents markedly reduce the risk of restenosis compared with bare metal stents. However, it is not known whether there are differences in effectiveness between bare metal and sirolimus-eluting stents in patients with total coronary occlusions. METHODS AND RESULTS In a prospective, randomized, single-blind, 2-center trial, we enrolled 200 patients with total coronar...
BACKGROUND Lipid-rich plaque (LRP) is thought to be a precursor to cardiac events. However, its clinical significance in coronary arteries has never been systematically investigated. OBJECTIVES This study investigated the prevalence and clinical significance of LRP in the nonculprit region of the target vessel in patients undergoing percutaneous coronary intervention (PCI). METHODS The stud...
OBJECTIVES The purpose of this research was to perform a feasibility study of prophylactic coronary revascularization in patients with preoperative extensive stress-induced ischemia. BACKGROUND Prophylactic coronary revascularization in vascular surgery patients with coronary artery disease does not improve postoperative outcome. If a beneficial effect is to be expected, then at least those w...
BACKGROUND The impact of percutaneous coronary intervention (PCI) on chronic total occlusion in patients with well-developed collaterals is not clear. METHODS AND RESULTS A total of 640 chronic total occlusion patients with collateral flow grade ≥2 were divided into 2 groups; chronic total occlusion patients either treated with PCI (the PCI group; n=305) or optimal medical therapy (the optima...
OBJECTIVES We performed the long-term (5-year) follow-up of a large cohort of patients who underwent drug-eluting stent (DES) or coronary artery bypass graft (CABG) surgery for multivessel revascularization. BACKGROUND Limited information is available on very long-term outcomes after multivessel DES treatment relative to CABG. METHODS We evaluated 3,042 patients with multivessel disease who...
BACKGROUND The safety and efficacy of the slow-release, polymer-based, paclitaxel-eluting stent after implantation in a broad cross section of de novo coronary lesions at 1 year are unknown. METHODS AND RESULTS In the TAXUS-IV trial, 1314 patients with single de novo coronary lesions 10 to 28 mm in length, with reference-vessel diameter 2.5 to 3.75 mm, coverable by a single study stent, were ...
Background—The safety and efficacy of the slow-release, polymer-based, paclitaxel-eluting stent after implantation in a broad cross section of de novo coronary lesions at 1 year are unknown. Methods and Results—In the TAXUS-IV trial, 1314 patients with single de novo coronary lesions 10 to 28 mm in length, with reference-vessel diameter 2.5 to 3.75 mm, coverable by a single study stent, were pr...
BACKGROUND Understanding of the risk conferred by functionally insignificant lesions in multiple coronary vessels is limited. We investigated the prognostic implications of coronary artery disease (CAD) based on 3-vessel fractional flow reserve (FFR). METHODS AND RESULTS A total of 1,136 patients underwent FFR measurement in the 3 major epicardial arteries. We defined vessels with "Moderate C...
The internal thoracic vein is a conduit that has not been thoroughly investigated in literature as long term patency and outcomes are unknown. We present a case where the right internal thoracic vein (RITV) was used to extend a short right internal thoracic artery (RITA). The elongated composite conduit was then anastomosed to the right coronary artery (RCA). A 61-year-old male patient was refe...
