OBJECTIVES: This study was performed to evaluate the long-term vascular response of the first series of patients treated by a novel ultra-low profile, guidewire-based self-expanding stent system (Sparrow stent) using serial intravascular ultrasound (IVUS). BACKGROUND: The long-term vascular response and stent geometry change after self-expanding stent implantation are not known. METHODS: The CARE 1 trial was a single-arm feasibility study of the Sparrow stent in patients with small-vessel disease. Twenty patients were included in this prospective IVUS study, and serial volumetric IVUS analysis was performed after stent implantation and at 6- and 12-months follow up. RESULTS: Serial volumetri..View full abstract
