Long-term outcomes after management of restenosis or thrombosis of drug-eluting stents.

OBJECTIVES: The purpose of this study was to examine the outcomes of patients who developed coronary in-stent restenosis (ISR) or stent thrombosis (STH) inside drug-eluting stents (DES). BACKGROUND: Drug-eluting stents have markedly reduced the incidence of restenosis. However, when restenosis occurs within a DES, its optimal management remains unclear. METHODS: We retrospectively analyzed clinical and angiographic data from 92 patients who underwent revascularization for ISR (n = 84) or STH (n = 8) within a DES at our institution. Regular follow-ups were available up to 2 years. We recorded the occurrence of major adverse cardiac events (MACE), defined as deaths from all causes, myocardial infarction (MI), or target lesion revascularization (TLR), among patients treated by the "DES sandwich" technique or by other treatment methods. RESULTS: In-hospital MACE included 1 periprocedural MI and 2 deaths. Over a mean follow-up of 15 +/- 6 months, the overall rates of death, MI, and TLR were 8.7%, 2.2%, and 30.6%, respectively. By actuarial analysis, the 12-month TLR and MACE rates were 28.2% and 42.9%, respectively. CONCLUSIONS: Current treatments of ISR or STH in DES are associated with a high long-term rate of MACE.     

Three-year follow-up after intracoronary beta-radiation therapy for in-stent restenosis.

BACKGROUND: Most studies that proved intracoronary radiation therapy (IRT) to be highly effective to reduce recurrent restenosis after treatment of in-stent restenosis (ISR) have looked at time periods up to 12 months. Whether the beneficial effect from radiation is sustained during long-term follow-up remains a concern. This study sought to evaluate the effectiveness of IRT using a beta-emitter during a 3-year follow-up period. METHODS: One hundred twenty-eight consecutive symptomatic patients (mean age, 63 +/- 11 years) with 134 in-stent restenotic lesions were treated for ISR with IRT (noncentred beta-emitter, Novoste; radiation dosis 21.1 +/- 3.1 Gy). Six-month angiographic follow-up was obtained in 104 patients (81%) with 105 lesions (78%). All patients underwent 36-month clinical follow-up. RESULTS: Six-month angiographic restenosis rate was 22% in stent (29% in lesion) with an in-stent late loss of 0.49 +/- 0.62 mm. Target lesion resvascularization (TLR) at 6-month follow-up was performed in 23 cases (18%). MACE (death, myocardial infarction, and target vessel revascularisation) was observed in 24 patients (19%). At 36-month follow-up, TLR increased to 36 cases (28%) and MACE was observed in 47 patients (37%). In a multivariate analysis, minimal lumen diameter before treatment of ISR using IRT was the only predictor of recurrent TLR at 36 months (OR = 0.131; 95% CI, 0.068-0.254; p = 0.002). In a subgroup of patients (N = 15) without restenosis at 6-month angiography but with clinically driven recurrent late angiography (mean, 18 +/- 7 months); in-lesion late loss increased from 0.47 +/- 0.54 mm at 6 months to 1.27 +/- 0.76 mm at repeated angiography (p = 0.005). CONCLUSION: There is a considerable number of delayed recurrent restenosis post IRT for ISR. This is due to ongoing late loss more than 6-month post IRT. The minimal lumen diameter before IRT predicts the need for recurrent TLR at 36 months.     

Use of Taxus polymer-coated paclitaxel-eluting stents for treatment of in-stent restenosis in real world patients: results of clinical and angiographic follow-up at six months in a single-center registry.

OBJECTIVE: To evaluate the safety and efficacy of Taxus paclitaxel-eluting stents in a real world group of unselected patients with coronary in-stent restenosis (ISR) lesions. METHODS: This is a prospective single-center registry of a consecutive series of 94 patients with 104 ISR lesions, without previous brachytherapy, over a period of 1 year. Quantitative coronary angiographic analyses were performed at baseline and at 6-month angiographic follow-up. Clinical follow-up were obtained at 6 months. RESULTS: Pre-intervention mean reference vessel diameter was 2.62 +/- 0.50 mm and mean lesion length was 13.95 +/- 6.78 mm. Baseline ISR patterns were mostly either Type I focal (32.7%) or Type II diffuse intrastent (48.1%). At 6-month angiographic follow-up, the in-stent and in-segment binary restenosis was 3.8% (4/105) and 7.6% (8/105) respectively, and the in-stent and in-segment late loss was 0.30 +/- 0.50 mm and 0.57 +/- 0.54 mm, respectively. Seven of these eight restenosed lesions had a diffuse or proliferative ISR pattern prior to intervention. Lesions that restenosed had longer mean stent length per lesion (37.3 mm vs. 22.5 mm in nonrestenosed group; P = 0.001) and more likely to have had a pattern of total occlusion pre-intervention (25.0% vs. 3.1% in nonrestenosed group; P = 0.046). At 6-month clinical follow-up, the MACE rate was 8.5% and target lesion revascularization rate was 7.4%. There was no death but subacute stent thrombosis occurred in 1 patient (1.1%) at 3 days after intervention. CONCLUSIONS: Paclitaxel-eluting Taxus stent for the treatment of ISR effectively suppresses recurrent neointimal proliferation, and was safe and efficacious at 6-month follow-up.     

Registry data evaluating the effectiveness of drug-eluting stents for the treatment of symptomatic in-stent restenosis

BACKGROUND: In this new-era of drug-eluting stents (DES) the impact of symptomatic in-stent restenosis (ISR) is diminishing. However, world wide bare-metal stents remain widely used and therefore, it is imperative to establish a simple and effective form of treatment. The objective of this registry database was to evaluate the 'real-world' effectiveness of DES for the treatment of symptomatic bare-metal stent ISR. METHODS: All patients presenting with symptomatic ISR were evaluated between February 2003 and February 2005. Patients had 9-month angiographic follow-up with primary endpoint evaluation of binary restenosis (>50%). Secondary endpoints included in-segment late loss, target lesion revascularization (TLR) and the difference in late loss between sirolimus (n=23) and paciltaxel (n=36) eluting stents. RESULTS: Fifty eight patients with fifty nine ISR lesions were evaluated, 36% of patients had diabetes mellitus. All procedures were performed safely with no adverse peri-procedural events documented. At 9-month follow-up the median in-segment late loss was 0.24 mm (IQR 0.1, 0.53), with a binary restenosis rate of 17%. At long-term follow-up greater than 1 year, the incidence of TLR was 10%. No difference in the angiographic parameter of in-segment late loss was seen between the sirolimus and paclitaxel-eluting stents. CONCLUSIONS: In this cohort of patients with long-term angiographic and clinical follow-up, DES is an effective and safe treatment for symptomatic bare-metal stent ISR.

Unprotected left main coronary artery stenting with zotarolimus (Endeavor) drug‐eluting stents

Objectives: To report the safety and efficacy of zotarolimus eluting stents for treatment of unprotected left main coronary artery disease. Background: Percutaneous stent insertion is an increasingly popular alternative to bypass surgery for the management of left main (LM) coronary artery disease. While data support the use of sirolimus‐ and paclitaxel‐coated stents in the LM coronary artery, there are no published series reporting results with Endeavor (zotarolimus) stents, particularly in the context of unprotected left main (ULM) lesions. Methods: We retrospectively identified 40 consecutive patients who had ULM disease treated with Endeavor stents (ZES) and who had follow‐up angiography. The primary endpoint was the prevalence of major adverse cardiac events (MACE), including cardiac/unexplained death, nonfatal myocardial infarction (MI), and in‐stent restenosis (ISR)/target lesion revascularization (TLR). Results: Angiographic and procedural success was achieved in all cases. Follow‐up angiography occurred on average 5.6 ± 0.9 months after the index procedure. There were three incidences of ISR requiring TLR and another patient who had a NSTEMI in the follow‐up period. At late follow‐up (12.4 ± 1.8 months) three patients underwent CABG (one for RCA stenosis) and four patients died without knowledge of the status of the ULM stent (two cardiovascular and two deaths related to cancer progression). Conclusions: In conclusion, our experience with Endeavor stents for the treatment of ULM disease demonstrates excellent angiographic and clinical outcomes, with a 7.5% ISR/TLR rate and a 15% MACE rate, respectively, at an average clinical follow‐up of 12.4 months. © 2011 Wiley Periodicals, Inc.
