Coronary artery stenting: Indications and cost implications

MR imaging in the presence of vascular stents: A systematic assessment of artifacts for various stent orientations, sequence types, and field strengths

“…The latter controls are often indicated in cases with suspected restenosis of the vessels or possible graft migration (1)(2)(3)(4)(5)(6)8). Possible structural damages due to continuous mechanical forces on materials with limited elasticity are also of interest (1,4,7), but effects on MR images were not tested in the present study. The main drawback of MRI is its sensitivity to susceptibility effects, which were found to be clearly more pronounced in steel stents compared with stents available for similar clinical indications but consisting of nitinol or Mediloy.…”

“…Although many experimental (1,2,7,9,12) and clinical studies (3,4,6) on stents have been published in the last several years, only a few studies have reported on MRI in the presence of stents of different materials and structures (13)(14)(15)(16)(17)(18). Previous reports have focused on in vitro (13,14,16 -18) and animal (15) studies using particular settings, without systematic variations in imaging parameters.…”

Long-term survival in 11,661 patients with multivessel coronary artery disease in the era of stenting: A report from the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease (APPROACH) Investigators

“…This study examines survival in patients with MVD in a large multicenter regional setting in a transitional period of increasing stent utilization. [6][7][8] An association is observed between treatment with CABG as well as PCI and favorable cumulative survival up to 5 years compared with medical therapy alone, after adjustment for important risk factors and comorbid conditions. Adjusted hazard ratios for mortality for all recorded baseline characteristics and comorbid conditions.…”

Systematik der Artefakte metallischer Gefäßprothesen (Stents) in der MRT

“…Zahlreiche experimentelle [1, 2, 7, 9,12 -14] und klinische Studien [3,4,6] mit Stents beschreiben den Einsatz der vaskulären Implantate. Systematische Untersuchungen zur MR-Bildgebung bei Anwesenheit unterschiedlicher metallischer Stents mit verschiedenen Sequenztypen und Orientierungen sind bislang aber nur selten angestellt worden [12 -21].…”
