Objectives This study sought to determine whether several anatomic or evolving characteristics of the coarctation may create challenging conditions for treatment. Background Stent repair of coarctation of aorta is an alternative to surgical correction. Methods We analyzed our 21-year experience in the percutaneous treatment of complex coarctation of aorta. Adverse conditions for treatment were as follow: 1) complete interruption of the aortic arch (n = 11); 2) associated aneurysm (n = 18); 3) complex stenosis (n = 30); and 4) the need for re-expansion and/or restenting (n = 21). Twenty patients (33%) belonged to more than 1 group. Ten interruptions were type A and 1 was type B. The mean length of the interrupted aorta was 9 ± 11 mm. The associated aneurysms were native in 8 patients and after previous intervention in 10 patients. Aneurysm shapes were fusiform in 8 patients and saccular in 10. The following characteristics defined complex stenosis as long diffuse stenosis, very tortuous coarctation, or stenosis involving a main branch or an unusual location. Patients previously stented at an early age, required re-expansion and/or restenting after reaching 16 ± 5 years of age. Results Two patients had died by 1-month follow-up. The remaining 58 patients did well and were followed-up for a mean period of 10 ± 6 years. Late adverse events occurred in 3 patients (5%). All remaining patients are symptom-free, with normal baseline blood pressure. Imaging techniques revealed good patency at follow-up without associated aneurysm or restenosis. The actuarial survival free probability of all complex patients at 15 years was 92%. Conclusions Stent repair of complex coarctation of aorta is feasible and safe. Initial results are maintained at later follow-up. [ABSTRACT FROM AUTHOR]

Objectives: The goal of this study was to assess the immediate and long-term outcomes in patients undergoing percutaneous coronary intervention (PCI) for in-stent restenosis (ISR) in an unprotected distal left main coronary artery (UDLM). Background: PCI for UDLM-ISR can be complex. Limited information is available on procedural and clinical outcomes. Methods: Between May 2002 and February 2011, UDLM-ISR after drug-eluting stent implantation was observed in 79 of 1,102 patients (7%). Seventy-five were treated by repeat PCI using a simple approach (balloon/in-stent implantation) or a complex strategy (additional stent/double-stenting technique). A diagnosis of mild or severe restenosis was considered depending on the number of bifurcation segments affected (1 vs. >1). Major adverse cardiac events (MACE) were defined as cardiac death, target lesion revascularization, and myocardial infarction. Results: ISR treatment was performed using a simple approach in 44 (58%) patients, and using a complex strategy in 31 (42%). After 46 ± 26 months, the MACE rate was 22%. Patients treated with a simple approach had a lower incidence of MACE at follow-up compared with patients treated with a complex strategy, regardless of the restenosis extent (mild restenosis: 93% vs. 67%, p < 0.05; severe: 70% vs. 23%, p < 0.05). On Cox regression analysis, diabetes was the only predictor of MACE (hazard ratio [HR]: 4.94; 95% confidence interval [CI]: 1.03 to 23.70; p < 0.05), whereas a simple strategy for ISR treatment was associated with lower risk (HR: 0.25; 95% CI: 0.08 to 0.79; p = 0.02). Conclusions: PCI for UDLM-ISR is safe and feasible, with a high rate of procedural success and an acceptable long-term MACE rate. A simple strategy, when applicable, appears to be a good treatment option, associated with a lower event rate at follow-up. [Copyright &y& Elsevier]

The present report compared the incidence of 1-year clinical events in patients with bifurcation lesions that had been treated with a simple approach who were randomized to either a simultaneous final kissing balloon (KB) or an isolated side-branch (SB) balloon post-dilation. From February 2007 to December 2008, 293 patients with all types of Medina bifurcation lesions were enrolled in a prospective study. All patients underwent implantation of a sirolimus- or everolimus-eluting stent across the bifurcation and provisional SB stenting. Patients with no SB ostial compromise or those needing a second stent were excluded from the present study (n = 49). The eligible patients were randomly assigned to treatment with final KB inflation (n = 124, KB group) or isolated balloon after dilation (n = 120, non-KB group). No significant differences were found between the patients from the KB and non-KB groups in terms of age, risk factors, clinical status, or location of the bifurcation lesions. The angiographic data and immediate results were also similar in both groups. Four patients experienced a non–Q-wave acute myocardial infarction in the hospital: three (2%) from the KB group and one (1%) from the non-KB group. Two in-hospital deaths occurred in the non-KB group. Target lesion revascularization was required in 7 patients (3%): 5 from the KB group and 2 from the non-KB group. Late mortality occurred in 3 patients from the KB group and 2 patients from the non-KB group. The incidence of major events at 1 year (death, target lesion revascularization, or acute myocardial infarction) was similar in both groups: 11 (9%) from the KB group and 7 (6%) from the non-KB group (p = NS). In conclusion, no differences in the clinical outcome at 1 year of follow-up were observed between the patients with bifurcation lesions treated with a simple approach and either a simultaneous final KB or an isolated SB balloon post-dilation.
