“…We previously reported a similar finding, 11) and other studies have also shown that a small minimum lumen diameter or a small percent diameter stenosis after the procedure are predictive factors of major adverse cardiac events after coronary stenting. 12,13) Therefore, since the final result (residual diameter stenosis) after coronary stenting should be one of the most important factors for target lesion revascularization, interventional cardiologists should achieve the optimal final diameter stenosis (≤ 20%) after stenting in order to avoid target lesion revascularization.…”

“…Strategies for complex coronary lesions : We previously reported that ACC/AHA lesion type was identified as an independent predictor of cardiac events after coronary stent implantation. 5,11) Recently, favorable results with drug-eluting stents for the treatment of de novo coronary lesions, including complex coronary lesions, have been reported. 14) Drug-eluting stents should be improved in the future to reduce in-stent restenosis, however, it is often difficult to cross the Sirolimus-coated Bx-Velocity stent (Cypher; Cordis, Johnson & Johnson) through an extremely angulated segment or tortuous lesion.…”

SUMMARYThe flexibility of the Multi-Link (ML) PENTA stent with platform 0.09 to 0.12-mmthick struts and 12% to 16% metal/artery coverage was improved to facilitate safe delivery in complex coronary lesions. The present study was designed to evaluate the clinical (9-month) and angiographic (6-month) results of the ML PENTA stent in complex coronary lesions (modified American College of Cardiology/American Heart Association lesion type B2 or C) and to determine independent factors correlated with target lesion revascularization. The study population consisted of 86 consecutive patients who had undergone successful coronary ML PENTA stent implantation for coronary artery disease from May 2003 to July 2004 in our hospital. During the follow-up period, cardiac events were documented in 21 (24.4%) of the 86 patients. Target lesion revascularization was required in 16 (18.6%) of the 86 patients. Single logistic regression analysis showed that target lesion revascularization was significantly correlated with lesion length > 2.0 cm, residual percent diameter stenosis after the procedure > 20%, and multiple stents. Multiple logistic regression analysis showed that residual percent diameter stenosis after procedure > 20% (P = 0.0125, odds ratio = 11.585) was the significant explanatory factor of target lesion revascularization. The results of the present study suggest that 9-month clinical and 6-month angiographic outcomes in patients with coronary artery disease treated using the ML PENTA stent were excellent and target lesion revascularization after coronary ML PENTA stent implantation was influenced by residual percent diameter stenosis after the procedure.

rospective randomized trials of coronary stenting using the Palmaz-Schatz (PS) stent (Cordis, Johnson & Johnson Interventional Systems, Miami, FL, USA) in stable angina 1,2 or acute myocardial infarction 3,4 have shown a reduced incidence of cardiac events associated with recurrent ischemia and a lessening of angiographic restenosis or occlusion. However, the PS stent has several disadvantages, including rigidity, difficult passage through tortuous anatomy or a site of calcification, poor scaffolding in the articulation site, and the need for multiple stents to treat lesions more than 15 mm in length. Therefore, several new (second generation) stents, including long stents, have been developed and can be more successfully delivered than the PS stent. The results of trials using the ACS MULTI-LINK (ML) stent (Guidant, Santa Clara, CA, USA), one of the recently developed stents, were similar to or slightly better than those of trials using the PS stent. 5,6 However, the follow-up periods in those trials were less than 9 months, so little is known about long-term (>12 months) outcome after ML stent implantation. The purpose of this study, therefore, was to evaluate the relatively long-term clinical outcome (2 years) of patients with coronary artery disease treated with the ML Circulation Journal Vol.66, October 2002 stent and to determine independent factors correlated with target lesion revascularization and cardiac events. Methods Patient PopulationThe study population consisted of 82 consecutive patients who had undergone successful coronary ML stent implantation for coronary artery disease (acute myocardial infarction in 29 patients, unstable angina in 17 and stable angina in 36) from January 1997 to December 1999. All the enrolled patients gave written informed consent, and the study protocol was based on the regulations of the hospital's ethics committee.The clinical characteristics, which included age, gender, coronary risk factors (hypertension, hypercholesterolemia, diabetes mellitus, smoking), indications for angioplasty, site of angioplasty, and drug treatment given after coronary stenting (nitrates, nicorandil, calcium antagonist, angiotensin-converting enzyme inhibitors, -blockers, and antiplatelet therapy), are shown in Table 1. Patients were defined as hypertensive if diastolic blood pressure was at least 90 mmHg and/or systolic blood pressure was at least 140 mmHg or if they were taking antihypertensive medication. Those patients whose serum total cholesterol concentration was at least 220 mg/dl or who were taking antihypercholesterolemic medication were defined as having hyperchoresterolemia. Those patients whose fasting glucose concentration was at least 126 mg/dl and/or hemoglobin A1c at least 6.5% before drug or dietary treatment for at Results of trials using the ACS MULTI-LINK (ML) stent, one of the new generation stents, were similar to or slightly better than those of trials using the Palmaz-Shatz stent.
