Published: July 2011

AbstractBackground: Intra myocardial hemorrhage lesions (IMH) are underdiagnosed complication of ST elevation myocardial infarction (STEMI). We sought to determine the incidence, predictors and the prognostic value of IMH in STEMI using cardiac MR imaging (CMR) techniques. Methods: We screened for inclusion consecutive patients with STEMI treated by percutaneous coronary intervention (PCI) within the first 12 hr of evolution. IMH lesions were identified on T2‐weighted sequences on CMR between days 4 and 8 after PCI. Adverse cardiac events were defined as a composite of death + severe ventricular arrhythmias + acute coronary syndrome + acute heart failure. Results: N = 114 patients were included and n = 11 patients (10%) presented IMH lesions. Patients with IMH lesions had a larger myocardial infarction extent (25.6 ± 1.8 vs. 13.5 ± 1.0 % LV mass, P < 0.01), microvascular obstructive lesions extent (4.6 ± 1.0 vs. 1.3 ± 0.3% LV mass, P < 0.01) and lower LV ejection fraction (40.7 ± 2.3% vs. 50.7 ± 1.3%, P < 0.01). The value of glycemia at admission was an independent predictor of IMH development (Odd ratio 1.8 [1.1–2.8] per mmol l−1, P = 0.01). The incidence of adverse cardiac events was higher in the IMH group than in the non‐IMH group during the first year following STEMI (P = 0.01, log‐rank analysis). Cox regression analysis identified the presence of IMH lesions as an independent predictor of adverse clinical outcome (Hazard Ratio = 2.8 [1.2–6.8], P = 0.02). Conclusion: Our study indicates that IMH is a rare but severe finding in STEMI, associated with a larger myocardial infarction and a worse clinical outcome. Per‐PCI glycemia might influence IMH development. © 2011 Wiley Periodicals, Inc.

Published: July 2011

AbstractObjective: To evaluate the procedural safety and filter efficiency of Lumen Biomedical FiberNet® embolic protection system in conjunction with primary stenting of ostial atherosclerotic renal artery lesions. Background: There is limited data regarding the utility of distal embolic protection devices in renal artery angioplasty and stenting. Methods: Patients with angiographically severe (≥70%) renal artery stenosis were prospectively enrolled if one or more inclusion criteria met: resistant hypertension, progressive chronic kidney disease, unexplained heart failure, or flash pulmonary edema. Patients underwent renal artery angioplasty and stenting with utilization of the Lumen Biomedical FiberNet® EPS. The protection devices and aspirate were analyzed for degree of atheromatous particles. Procedural safety and clinical outcomes were assessed through 6 months. Results: Twenty patients were prospectively enrolled at five centers; average age 73.8 (±9.5) years, mean baseline eGFR 60.8 cm3 min−1. Twenty‐five renal artery stenting procedures were performed. Device and procedural success were achieved in 100% of cases. All patients tolerated the procedure without any adverse events. Embolic debris was captured in all cases. Debris analysis of the distal protection system displayed an average post procedure atheroma area of 51.31 mm2. There was no clinical evidence of peripheral atheroembolization through 30‐days follow‐up. No subjects progressed to temporary or permanent renal replacement therapy. Favorable trends in blood pressure control were observed at 6 months. Conclusion: The Lumen Biomedical FiberNet® embolic protection system is a safe and feasible method to prevent atheroembolization associated with angioplasty and stenting of renal artery ostial lesions. © 2011 Wiley Periodicals, Inc.

Published: July 2011

AbstractPercutaneous closure of secundum atrial septal defect and patent foramen ovale has gained widespread use in recent years. We present a small series of four cases in which a “cobra‐like” formation occurred in an Occlutech Figulla device during the deployment of the left disk, and propose a technique that may resolve this problem. © 2011 Wiley Periodicals, Inc.

Published: July 2011

AbstractBackground: Restenosis after endovascular treatment for superficial femoral artery (SFA) disease remains a significant clinical issue. We assessed whether cilostazol reduce restenosis after SFA stenting with self‐expandable nitinol stent. Methods: The study was a multicenter, prospective maintained database, retrospective analysis. From April 2004 to December 2009, 861 consecutive patients (mean age 71 years, 71% male) who underwent successful stenting for de novo lesions were retrospectively identified. Of them, 492 received cilostazol (cilostazol(+)) and 369 did not receive cilostazol (cilostazol(−)) after procedure. Propensity‐score analyses matched 281 cilostazol(+) with 281 cilostazol (−) group. Primary endpoint was binary restenosis rate. Secondary endpoints were reocclusion, all‐cause mortality and limb salvage in patients with critical limb ischemia (CLI). Restenosis was defined as >2.4 of peak systolic velocity ratio by duplex. Results: Mean follow‐up period was 25 months. According to analysis of matched pairs, binary restenosis rates were significantly lower (31.2% vs. 42.9% at 5‐year, P = 0.02). In‐stent re‐occlusion rate tended to be lower in patients who received cilostazol (10.8% vs. 18.2% at 5‐year, P = 0.09) compared with control. No significant difference of all‐cause mortality (21.4% vs. 18.3% at 5‐year, P = 0.84) and limb salvage rate in patients with CLI (86.2% vs. 78.5% at 5‐year, P = 0.29) was found between both groups. After adjustment for prespecified risk factors, cilostazol was an independent negative predictor of restenosis. In subgroup analysis, male, age <75 years, claudicant patients, TASCII C/D, small vessels and poor runoff vessel was significantly lower in binary restenosis. Conclusions: Cilostazol reduced restenosis after SFA stenting with self‐expandable nitinol stent and it seems to be more effective in high‐risk patients for restenosis. © 2011 Wiley Periodicals, Inc.
Stereoselective Oxidation of 1‐Phenyl‐1,2‐propanediol Mediated by Microorganisms

Published: July 2011

AbstractThe enantioselective oxidation of (1R,2S)‐1‐phenyl‐1,2‐propanediol [(1R,2S)‐1], mediated by baker’s yeast, gave (−)‐(S)‐1‐phenyl‐2‐hydroxy‐1‐propanone [(S)‐2] in 64 % isolated yield and 93 % ee. Kinetic experiments of the bio‐oxidation of (±)‐anti‐1 revealed that the enantiomer (1R,2S)‐1 was more reactive than (1S,2R)‐1. Therefore, this result allowed us to devise a kinetic resolution experiment to obtain (1S,2R)‐1 in >99 % ee from (±)‐anti‐1. The preparation of (1S,2R)‐1 is interesting, as it is the antipode of the product obtained by the reduction of 1‐phenyl‐1,2‐propanedione using baker’s yeast. Other microorganisms, such as Micrococcus luteus, Candida albicans, and Geotrichum candidum, were also used for kinetic resolution experiments of (±)‐anti‐1. The best result was obtained using Geotrichum candidum, which gave (1S,2R)‐1 in 32 % yield and 99 % ee.
