The Short-Term and One-Year Clinical Outcomes in Patients with Optical Coherence Tomography-Guided Magmaris Implantation: A Real-World Clinical Practice

Abstract

Aims. We aimed to evaluate the acute performance and short- and long-term outcomes of optical coherence tomography (OCT)-guided Magmaris deployment. Methods. This was a retrospective study of 28 consecutive patients (23 men, mean age: 59.8 years) with 28 Magmaris implantations in de novo coronary lesions. OCT was performed at the baseline and after the final postdilatation. The choice of stent and postdilatation balloon size was based on OCT measurements. The following indices were determined using OCT: prestenting minimum lumen diameter and area, poststenting minimum lumen diameter and area, acute lumen area gain, residual area stenosis, eccentricity and symmetry indices, incomplete strut apposition, strut fracture, tissue prolapse, and edge dissection. Results. Before the stenting, OCT analysis revealed a minimal lumen area of 1.55 ± 0.59 mm², a minimal lumen diameter of 1.19 ± 0.38 mm, a minimal scaffold area of 6.78 ± 1.58 mm², and a minimal scaffold diameter of 2.88 ± 0.50 mm². The prolapse area was 1.2 ± 1.5 mm². The mean percentage of RAS was 13.3 ± 7.1% and 6 (21.4%) patients had scaffold RAS more than 20%. Only one proximal edge intimal dissection was noted. The mean eccentricity index was 0.86 ± 0.04 and symmetry index 0.33 ± 0.08. ISA analysis showed that the percentage of malapposed struts was 1.5%. There were no short-term cardiovascular events, and only 2 incidents of target lesion failure (TLF) occurred 13 months later. Conclusion. The Magmaris has excellent acute mechanical performance and no short-term cardiovascular events occurred. There were only 2 TLFs that occurred 13 months later. It is suitable and feasible to treat vessels using the Magmaris.
