Objectives: The FINESSE-ANGIO (Facilitated Intervention with Enhanced Reperfusion Speed to Stop EventsAngiographic) study evaluated acute treatment effects on infarct-related artery (IRA) patency and angiographic correlates of coronary microcirculatory function. Background The FINESSE trial evaluated the effects on clinical outcomes of primary percutaneous coronary intervention (PCI) facilitated with precatheterization laboratory administration of abciximab with half-dose reteplase (combination-facilitated group), abciximab alone (abciximab-facilitated group), or with abciximab administered immediately before the procedure (primary PCI). Methods The FINESSE-ANGIO substudy compared the effects of the 3 treatment strategies on patency (TIMI [Thrombolysis In Myocardial Infarction] flow grade 2/3) of the IRA at basal coronary angiography. The secondary efficacy end points were corrected TIMI frame count, percentage of patients achieving TIMI flow grade 3, and the percentage achieving myocardial blush grade 2/3 of the IRA at post-PCI angiography. All angiographies were evaluated at a central core laboratory. Results Of the 2,452 FINESSE patients, 637 were included in the FINESSE-ANGIO substudy. Patients in the combination-facilitated group exhibited significantly higher rates of baseline IRA patency compared with the abciximab-facilitated and the primary PCI groups (76.1% vs. 43.7% and 32.7%, respectively; p < 0.0001 for both; p = 0.025 abciximab-facilitated vs. primary PCI). There were no significant differences in the post-PCI corrected TIMI frame count (17.1 ± 15.8, 17.4 ± 17.3, and 15.8 ± 14.1) or the rates of post-PCI TIMI flow grade 3 (79.8%, 77.7%, and 76.6%), myocardial blush grade 2/3 (85.6%, 79.5%, and 86.4%), respectively. Conclusions Precatheterization laboratory administration of abciximab alone and especially in combination with half-dose reteplase resulted in higher rates of IRA patency at baseline coronary angiography compared with no pre-treatment. However, post-procedural angiographic and microcirculatory variables were unaffected by facilitation therapy. © 2010 American College of Cardiology Foundation.

Background A retrograde approach improves the success rate of percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs). Objectives The authors describe the European experience with and outcomes of retrograde PCI revascularization for coronary CTOs. Methods Follow-up data were collected from 1,395 patients with 1,582 CTO lesions enrolled between January 2008 and December 2012 for retrograde CTO PCI at 44 European centers. Major adverse cardiac and cerebrovascular events were defined as the composite of cardiac death, myocardial infarction, stroke, and further revascularization. Results The mean patient age was 62.0 ± 10.4 years; 88.5% were men. Procedural and clinical success rates were 75.3% and 71.2%, respectively. The mean clinical follow-up duration was 24.7 ± 15.0 months. Compared with patients with failed retrograde PCI, successfully revascularized patients showed lower rates of cardiac death (0.6% vs. 4.3%, respectively; p < 0.001), myocardial infarction (2.3% vs. 5.4%, respectively; p = 0.001), further revascularization (8.6% vs. 23.6%, respectively; p < 0.001), and major adverse cardiac and cerebrovascular events (8.7% vs. 23.9%, respectively; p < 0.001). Female sex (hazard ratio [HR]: 2.06; 95% confidence interval [CI]: 1.33 to 3.18; p = 0.001), prior PCI (HR: 1.73; 95% CI: 1.16 to 2.60; p = 0.011), low left ventricular ejection fraction (HR: 2.43; 95% CI: 1.22 to 4.83; p = 0.011), J-CTO (Multicenter CTO Registry in Japan) score ≥3 (HR: 2.08; 95% CI: 1.32 to 3.27; p = 0.002), and procedural failure (HR: 2.48; 95% CI: 1.72 to 3.57; p < 0.001) were independent predictors of major adverse cardiac and cerebrovascular events at long-term follow-up. Conclusions The number of retrograde procedures in Europe has increased, with high percents of success, low rates of major complications, and good long-term outcomes. © 2015 American College of Cardiology Foundation.

Concerns regarding radiation exposure and its effects during pregnancy are often quoted as an important barrier preventing many women from pursuing a career in Interventional Cardiology. Finding the true risk of radiation exposure from performing cardiac catheterization procedures can be challenging and guidelines for pregnancy exposure have been inadequate. The Women in Innovations group of Cardiologists with endorsement of the Society for Cardiovascular Angiography and Interventions aim to provide guidance in this publication by describing the risk of radiation exposure to pregnant physicians and cardiac catheterization personnel, to educate on appropriate radiation monitoring and to encourage mechanisms to reduce radiation exposure. Current data do not suggest a significant increased risk to the fetus of pregnant women in the cardiac catheterization laboratory and thus do not justify precluding pregnant physicians from performing procedures in the cardiac catheterization laboratory. However, radiation exposure among pregnant physicians should be properly monitored and adequate radiation safety measures are still warranted. Copyright © 2011 Wiley-Liss, Inc.

Chronic critical limb ischemia (CLI) still represents the most common cause for amputation and frequently the possibility for peripheral revascularization, particularly in below knee (BK) arteries, is not adequately evaluated before amputation. This may also be due to the fact that even today, there's some confusion about results of the endovascular treatment in this territory. Diabetics, representing the population most frequently affected by CLI, have specific clinical characteristics, the so called diabetic foot syndrome, which cannot be compared with the situation in nondiabetic patients with ischemic ulcers. Measuring the success of BK endovascular therapy can be a difficult issue, considering that it is often the work of a multidisciplinary team. The clinical benefit of BK endovascular therapy often shows a large discrepancy from the primary patency. While ulcer healing, limb salvage, and reintervention rates are usually low after BK endovascular therapy, rates of restenosis remain excessively high. Nevertheless, the positive impact of revascularization on mortality, which mainly depends on the major amputation rate reduction, is also evident. This review article summarizes indications and clinical outcomes after BK endovascular therapy with special attention to the role of diabetes mellitus in patients with CLI. © 2009 Wiley-Liss, Inc.

Background: To present our experience of extended endovascular management for thromboangiitis obliterans (Buerger's disease) patients with critical limb ischemia (CLI). Methods: Between January 2005 and July 2010, a consecutive series of 17 Buerger's disease patients with CLI in 20 limbs were admitted and the diagnosis confirmed. The mean age of the patients was 41.5 years (standard error: ±1.7). All patients presented with history of smoking, one patient presented with hypertension, and eight patients presented with dyslipidemia. According to Rutherford classification, all patients were found to be between grades 3 and 5. Ultrasonography first, and angiography examination later, confirmed a severe arterial disease involving almost exclusively below-the-knee and foot arteries in all cases. A new approach for revascularization, defined as extended angioplasty of each tibial and foot artery obstruction, was performed to achieve direct perfusion of at least one foot artery. Results: An extensive endovascular treatment was intended in all patients with success in 19 of 20 limbs, achieving a technical success in 95%. No mortality or complication related to the procedure was observed. During a mean follow-up of 23 months (standard error: ±4.05), amputation-free survival with no need of major amputation in any case and sustained clinical improvement was achieved in 16 of the 19 limbs (84.2%) successfully treated, resulting in a 100% limb salvage rate (19/19). Conclusion: In this first experience, in patients with thromboangiitis obliterans, extended endovascular intervention was a feasible and effective revascularization procedure in case of CLI. High technical success, amputation-free survival, and sustained clinical improvement rates were achieved at midterm follow-up was achieved. © 2011 Annals of Vascular Surgery Inc.
