Background incidence of late malapposition after bare-metal stent implantation.
BACKGROUND Late stent malapposition has been reported to be an abnormal finding after vascular brachytherapy and, possibly, implantation of drug-eluting stents. It can only be detected if intravascular ultrasound (IVUS) is performed at follow-up. However, the "background" frequency of late stent malapposition after bare-metal stent implantation is not known. METHODS AND RESULTS We studied 206...
متن کاملLate stent malapposition after drug-eluting stent implantation: an intravascular ultrasound analysis with long-term follow-up.
BACKGROUND Late stent malapposition (LSM) after drug-eluting stent (DES) implantation has not been evaluated sufficiently in real-world practice. METHODS AND RESULTS We evaluated the incidence, mechanisms, predictors, and long-term prognosis of LSM after DES implantation in 557 patients (705 native lesions; sirolimus-eluting stent in 538 lesions and paclitaxel-eluting stent in 167 lesions) in...
متن کاملIntravascular ultrasound assessment of the mechanisms and results of brachytherapy.
Serial intravascular ultrasound (IVUS) studies have shown that restenosis in nonstented lesions and late lumen loss in reference segments contiguous with both stented and nonstented lesions is a balance between arterial remodeling and neointimal hyperplasia. Conversely, in-stent restenosis (ISR) is neointimal hyperplasia.1,2 The present review focuses on lessons learned from IVUS about mechanis...
متن کاملVolumetric intravascular ultrasound assessment of mechanisms and results of stent expansion in heart transplant patients.
BACKGROUND Percutaneous coronary intervention with stent placement for the treatment of patients with cardiac allograft vasculopathy is common, but data regarding stent behavior in this setting is lacking. OBJECTIVES We investigated mechanisms and potential differences in stent expansion among transplant patients vs. patients with native coronary artery atherosclerotic disease ("controls"). ...
متن کاملIncidence, mechanism, predictors, and long-term prognosis of late stent malapposition after bare-metal stent implantation.
BACKGROUND Predictors and long-term prognosis of late stent malapposition (LSM) after bare-metal stent (BMS) implantation are unknown. METHODS AND RESULTS We evaluated the incidence, mechanisms, predictors, and long-term prognosis of LSM after BMS implantation in 881 patients (992 native lesions) in whom intravascular ultrasound was performed at index and 6-month follow-up. LSM was defined as...
