Abstract

BACKGROUND: Although safety and efficacy of the beStent (Medtronic Inc., Santa Rosa, CA, USA) have been described, the long-term angiographic and clinical outcomes have yet to be investigated. The ROSE (Registry for Optimal beStent Evaluation) trial was designed to assess the procedural safety of single 15 mm beStent implantation, and the six-month angiographic and 12-month clinical outcomes of patients treated with this novel coronary stent. METHODS: Patients with angina and a single de novo lesion in a native coronary artery ≥83 of 2.75 mm diameter were included in this multicenter, prospective, observational trial. Clinical follow-up was obtained at one, six and 12 months. Angiography was performed before and after the stent implantation and at six months. The primary end-point included major adverse cardiac events (death, myocardial infarction and target lesion revascularization), major bleeding complications, and thrombotic occlusions at one-month follow-up. Secondary end-points were major cardiacevent-free survival at six- and 12-month follow-up and angiographic restenosis at six months. A total of 120 patients (80% male, mean age 58.6 +/- 10.6 years) with stable (48%) or unstable (44%) angina pectoris were allocated. The target vessel reference diameter pre-procedure was 2.85 +/- 0.52 mm. RESULTS: Minimal lumen diameter pre/post and at follow-up was 0.97 +/- 0.28 mm, 2.53 +/- 0.40 mm and 1.86 +/- 0.63 mm, respectively. Restenosis rate according to the >50% diameter stenosis criterion at six-month follow-up was 21.5%. At 12 months, the event-free survival rate was 75% (no deaths, two Q-wave and seven non-Q-wave infarctions, five bypass surgery interventions and 16 target lesion revascularizations), whilst 87% of the patients were free of angina pectoris. CONCLUSION: Despite the relatively high percentage of small vessels, the outcome of the ROSE trial is comparable to those observed in previous stent trials, indicating that the coronary beStent is safe and effective as a primary device for the treatment of native coronary artery lesions in patients with (un)stable angina pectoris.

Abstract

Background: Intracoronary thrombus is often problematic during percutaneous coronary intervention. Rinspiration is a new thrombectomy catheter system designed to mechanically disrupt and remove intravascular thrombus., Methods: Rinspiration thrombectomy was performed in 15 patients with angiographically visible thrombus in native coronary arteries (10 cases) and in saphenous grafts (5 cases). Indications included acute myocardial infarction in 11 patients and postinfarction ischemia in 4 patients., Results: The Rinspiration system appeared relatively simple to use. There were no device-related complications. Thrombectomy resulted in an improvement in thrombus grade from 3.8 +/- 1.6 to 2.5 +/- 1.7 (p = 0.02), and TIMI flow from 1.5 +/- 1.3 to 2.2 +/- 1.0 (p = 0.047). Stenting further improved thrombus grade to 0.8 +/- 1.6 and TIMI flow to 2.6 +/- 0.8. At 30-day follow up all patients remained free of repeat revascularization and reinfarction; 1 patient died from hemorrhagic stroke., Conclusions: The Rinspiration system appears capable of safely removing intracoronary thrombus and warrants further evaluation.
