Impact of intravascular ultrasound for the treatment of calcified infrarenal aortic stenosis: A case report study
Authors: Hara Masahiko , Nishino Masami 
Published: July 2008

AbstractWe report two cases of heavily calcified infrarenal aortic stenosis that were successfully treated by Intravascular ultrasound‐ (IVUS)‐guided stenting. Two middle‐aged women visited our hospital due to intermittent claudication. Diagnostic arteriography revealed possible infrarenal aortic stenosis even though the findings were equivocal. IVUS demonstrated heavily calcified atherosclerotic lesions and allowed the accurate assessment of the types and extents of the lesions to be treated in both cases. The patients successfully underwent stent implantation according to the findings of IVUS. IVUS significantly contributed to the interventional successes. © 2008 Wiley‐Liss, Inc.

AbstractBackground: Recanalization of coronary chronic total occlusions (CTOs) remains a clinical challenge, particularly when standard guidewire attempts fail. Objectives: We sought to determine the safety and efficacy of a novel method that used high‐frequency (20 kHz) vibration to fragment occlusive fibrous tissue and facilitate guidewire crossing into the distal vessel. Methods: A total of 125 patients with CTO, who failed at attempts of conventional guidewire recanalization after more than 5 min of fluoroscopy time, were enrolled in the study. The primary efficacy endpoint was the advancement of the CROSSER™ catheter through the occlusion and attainment of coronary guidewire positioning in the distal coronary lumen. The primary safety endpoint was the occurrence of death, myocardial infarction, clinical perforation, or target vessel revascularization within the first 30 days. Results: The average fluoroscopy time while delivering the CROSSER catheter was 12.4 min. CROSSER‐assisted guidewire recanalization was achieved in 76 (60.8%) procedures and a final diameter stenosis <50% was obtained in 68 (54.4%) of cases. Major adverse events occurred in 11 (8.8%) patients, lower than the predefined objective performance criteria. Angina frequency and quality of life were improved in patients with successful guidewire recanalization. Conclusions: We conclude that high‐frequency vibration using the CROSSER catheter is a safe and effective therapy for patients with CTO, which are refractory to standard guidewire recanalization. © 2008 Wiley‐Liss, Inc.

AbstractBackground:Treatment of patients with in‐stent restenosis (ISR) remains a challenge. We sought to compare results of sirolimus‐eluting stents (SES) with those of bare‐metal stents (BMS) in patients with ISR.Methods:The results obtained in the stent arm of two randomized studies were analyzed. The RIBS I study (450 patients with ISR) allocated 224 patients to BMS; the RIBS II study (150 patients with ISR) allocated 76 patients to SES. Complete 1‐year follow‐up was obtained in all 300 patients treated with stents.Results:Although inclusion/exclusion criteria were identical in the two studies, when compared with patients in the BMS group, patients in the SES arm had more adverse baseline characteristics, more diffuse lesions, and smaller vessels. However, late angiographic findings including in‐segment recurrent restenosis rate (11 vs. 38%, P < 0.001), minimal lumen diameter (2.52 vs. 1.63 mm, P < 0.001), and late loss (0.13 vs. 1.04 mm, P < 0.001) were significantly better after SES. The 1‐year event‐free survival was also significantly improved in the SES group (88 vs. 78%, P < 0.05), as the result of a lower requirement for repeated revascularizations (10.5 vs. 19.6%, P < 0.05). Prespecified subgroup analyses were consistent with the main outcome measures. After adjusting for (a) imbalances in baseline characteristics (restenosis OR 0.11 [95% confidence interval (CI) 0.03–0.36]; adverse events hazard ratios (HR) 0.33 [95% CI 0.13–0.84]) and (b) the propensity score (restenosis OR 0.08 [95% CI 0.03–0.28]; adverse events HR 0.24 [95% CI 0.09–0.66]), results of the SES group were superior to those obtained in the BMS group.Conclusions:When compared with BMS, SES improved the long‐term clinicaland angiographic outcome of patients with ISR. © 2008 Wiley‐Liss, Inc.
Subintimal tracking and re‐entry technique with contrast guidanc: A safer approach
Authors: Carlino Mauro , Godino Cosmo , Latib Azeem , Moses Jeffrey W. , Colombo Antonio 
Published: July 2008

AbstractObjectives: To assess the procedural and clinical outcomes from a modified subintimal tracking and re‐entry (STAR) procedure performed using contrast guidance. Background: Previous data showed that recanalizing a chronic total occlusion (CTO) with the STAR technique was possible. However, this technique was considered difficult and therefore has only been adopted by a limited number of experienced operators. Methods: Patients (n = 68) with a CTO of a native coronary artery treated by a single operator with this technique were included. Results: The right coronary artery was involved in 79.4%, the morphology was blunt in 77.9%, and CTO length was longer than 20 mm in 67.6%. Angiographic success rate was 80.9% with a 70.6% rate of complete recanalization. Stent implantation was performed in 82.3% of cases, with drug‐eluting stents (DES) implanted in the majority (92.7%). Procedural complications occurred in 10.3% of cases. There were no episodes of myocardial infarction during follow‐up, with 1 case (1.5%) of cardiac death. There were no cases of definite or probable stent thrombosis, and there was 1 (1.5%) possible stent thrombosis. The overall rate of in‐segment binary restenosis was 44.7%, and target lesion revascularization (TLR) was performed in 25% of lesions. The rate of TLR in lesions treated with DES was 29.4% and in those treated with bare‐metal stents was 50%. Conclusion: The contrast‐guided STAR technique appears to be feasible and relatively safe. However, this procedure is limited by a high rate of restenosis even with DES, and a second procedure may be necessary to obtain a definitive result. © 2008 Wiley‐Liss, Inc.
Transcatheter closure of patent ductus arteriosus and aorto‐pulmonary vessels using non‐ferromagnetic Inconel MReye embolization coils
Authors: Grifka Ronald G. , Fenrich Arnold L. , Tapio Jason B. 
Published: July 2008

AbstractObjectives. We report the use of non‐ferromagnetic embolization coils for transcatheter PDA closure. Background. Transcatheter patent ductus arteriosus (PDA) closure has been performed for 40 years. A number of devices have been used with varying degrees of success. Gianturco embolization coils have been used frequently since 1992 with excellent results. These coils are a stainless steel alloy, and create an artifact when subsequent MRI imaging is performed. Methods. Eight patients underwent right and left heart catheterization and transcatheter PDA closure. Angiography displayed a PDA with left to right shunting. The minimum PDA diameter was measured. An Inconel MReye coil was implanted using standard retrograde technique. A postimplant angiogram was performed. Evaluations were performed the following morning and after 2 months. Results. The median age was 5.5 years, median weight was 24 kg. The PDA minimum diameter was 1.7 mm (range 1.4–2.4 mm), with a median Qp:Qs=1.33:1. In all patients, the PDA was completely immediately closed using one Inconel coil. Two patients also had a small aorto‐pulmonary collateral vessel that was occluded using a separate Inconel coil. All patients had follow‐up evaluation the following day; the PDA remained completely occluded and there was no obstruction of the pulmonary artery branches or descending aorta. Seven patients had subsequent follow‐up and echocardiograms; the PDA remained completely occluded. There were no complications. Conclusion. The Inconel MReye coil is safe and effective for coil occlusion of small PDA and aorto‐pulmonary vessels. Additional studies are needed to define the maximum vessel diameter for Inconel coil occlusion. © 2008 Wiley‐Liss, Inc.

Published: July 2008

AbstractObjectives: The objective is to report the feasibility and technique of treating popliteal artery aneurysms (PAA) with a stent made of nitinol rings externally supported by thin polyester (Anaconda limbs). Background: PAA are the most common peripheral aneurysms. The main limitations of stents used in these settings are: short lengths, longitudinal and horizontal compliance mismatch; graft failure from angulation and movement at the joint level; and dislodgment. Methods: This is a prospective multicenter cohort study of consecutive symptomatic and asymptomatic PAA treated in tertiary vascular centers. Outcomes included patency of the stent and postoperative time‐to‐independent‐ambulation and to‐climb‐a‐flight‐of‐stairs. Results: Fourteen PAA were treated in 12 men, age 72 ± 3 years. The median ASA classification was 2.5. The length of artery covered was 147 ± 41 mm. The PAA diameter was 31 ± 5 mm, 6 were symptomatic. One stent was used in 6 aneurysms, two in 7, and three in 1. The average stent diameter was 10 ± 1 mm. The length of the proximal neck was 24 ± 6 mm with a diameter of 9.8 ± 1.9, and length of the distal neck 23 ± 3 mm with a diameter of 8.7 ± 1.2 mm. In 6 aneurysms, the stent crossed the knee joint. There was no mortality, and one stent occluded (primary patency 93% at 6 ± 3 months). The median hospital stay was 1.7 days, time to independent ambulation was 3 hr and the time to climbing a flight of stairs was 1 day. Conclusions: The use of Anaconda limbs for endovascular repair of PAA is feasible and safe. © 2008 Wiley‐Liss, Inc.

Published: July 2008

AbstractObjectives: We attempted to investigate incidence and predictors of recurrent in stent thrombosis (IST) after successful treatment of a first IST. Background: The occurrence of recurrent IST after successful treatment of a first IST may be a decisive factor for patient clinical outcome. However, incidence and predictors of recurrent IST are currently poorly described in the literature. Methods: Between 2003 and 2005, 2,190 patients underwent a percutaneous coronary intervention in our center. During a median follow‐up of 19.4 months, 49 patients (2.24%) presented a first definite IST. Patients presenting with a first IST were followed during an additional median period of 40 months. Their baseline characteristics were listed and cardiovascular events especially recurrent IST as defined by the Academic Research Consortium definition were systematically indexed. Results: Altogether 39 (80%) patients were successfully treated with an effective reperfusion after percutaneous coronary intervention. Fourteen (36%) patients presented a recurrent IST and three presented multiple recurrent IST. The median occurrence time of recurrent IST was 5 days, range between 1 and 11 days. Multivariate analysis identified history of neoplasia (HR = 11.53, 95% CI 2.32–57.37, P = 0.003), residual diameter stenosis (HR = 1.15, 95% CI 1.02–1.29, P = 0.02), and residual dissection after treatment (HR = 8.78, 95% CI 1.85–41.62, P = 0.006), as independent predictors of recurrent IST. Conclusion: Recurrent IST is a frequent and early event after successful treatment of a first IST. Our results suggest that mechanical factors like residual dissection and residual diameter stenosis should be carefully tracked down. In addition, patients with multiple recurrent IST and the early time course of recurrent IST also suggest a potential role of inadequate antiplatelet therapy. © 2008 Wiley‐Liss, Inc.

Published: July 2008

AbstractBackground: Patients who present with myocardial infarction (MI) and unprotected left main coronary artery (ULMCA) disease represent an extremely high‐risk subset of patients. ULMCA percutaneous coronary intervention (PCI) with drug‐eluting stents (DES) in MI patients has not been extensively studied. Methods: In this retrospective multicenter international registry, we evaluated the clinical outcomes of 62 consecutive patients with MI who underwent ULMCA PCI with DES (23 ST‐elevation MI [STEMI] and 39 non‐ST‐elevation MI [NSTEMI]) from 2002 to 2006. Results: The mean age was 70 ± 12 years. Cardiogenic shock was present in 24%. The mean EuroSCORE was 10 ± 8. Angiographic success was achieved in all patients. Overall in‐hospital major adverse cardiac event (MACE) rate was 10%, mortality was 8%, all due to cardiac deaths from cardiogenic shock, and one patient suffered a periprocedural MI. At 586 ± 431 days, 18 patients (29%) experienced MACE, 12 patients (19%) died (the mortality rate was 47% in patients with cardiogenic shock), and target vessel revascularization was performed in four patients, all of whom had distal bifurcation involvement (two patients underwent repeat PCI and two patients underwent bypass surgery). There was no additional MI. Two patients had probable stent thrombosis and one had possible stent thrombosis. Diabetes [hazard ratio (HR) 4.22, 95% confidence interval (CI) (1.07–17.36), P = 0.04), left ventricular ejection fraction [HR 0.94, 95% CI (0.90–0.98), P = 0.005), and intubation [HR 7.00, 95% CI (1.62–30.21), P = 0.009) were significantly associated with increased mortality. Conclusions: Patients with MI and ULMCA disease represent a very high‐risk subgroup of patients who are critically ill. PCI with DES appears to be technically feasible, associated with acceptable long‐term outcomes, and a reasonable alternative to surgical revascularization for MI patients with ULMCA disease. Randomized trials are needed to determine the ideal revascularization strategy for these patients. © 2008 Wiley‐Liss, Inc.
