Popis: Background— Limited long-term data exist on patients who have undergone drug-eluting stenting of very long lesions (requiring ≥60 mm of continuous stent) in native coronary arteries (“full-metal jacket”). Methods and Results— We examined consecutive procedures taking place between March 2002 and 2007 at 2 high-volume centers in Milan, Italy. Exclusion criteria were percutaneous coronary intervention for restenosis, percutaneous coronary intervention to a bypass graft, or percutaneous coronary intervention for acute ST-elevation myocardial infarction (MI). We identified 658 full-metal jacket lesions in 617 patients. Average age of the cohort was 62.0�10.6; 32.8% were diabetic, 51.5% had a previous MI, and 33.4% had undergone a previous percutaneous transluminal coronary angioplasty. Mean ejection fraction was 52.1�10.4%. The lesion was a chronic total occlusion in 33.0%. Median duration of clinical follow-up was 39 months (interquartile range, 28 to 50). Six-month follow-up was achieved in 97% of patients; 2-year follow-up was achieved in 91%. All-cause mortality rate was 7.3%; cardiac death rate was 3.6%. Non–procedure-related MI rates were 3.5%. Target lesion revascularization rates were 23.4%. There were 17 cases of Academic Research Consortium–defined definite or probable stent thrombosis (2.6%): 5 acute, 2 subacute, 6 late, and 4 very late. Ten of the 17 cases occurred while the patient was receiving dual antiplatelet therapy; 4 of the 17 after premature termination of 1 or both antiplatelets, and 3 of the 17 occurred while the patient was receiving single-antiplatelet therapy, after having completed the prescribed course of dual antiplatelet therapy. Conclusion— When very long lesions (≥60 mm) were treated using overlapping drug-eluting stents, 23.4% required a further procedure for restenosis at 3-year follow-up. However, MI, stent thrombosis, and cardiac mortality rates were relatively low.
