Objective. The most important step in the treatment of ST elevation myocardial infarction is to sustain myocardial blood supply as soon as possible. The two main treatment methods used today to provide myocardial reperfusion are thrombolytic therapy and percutaneous coronary intervention. In our study, reperfusion arrhythmias were investigated as if they are indicators of coronary artery patency or ongoing ischemia after revascularization. Methods. 151 patients with a diagnosis of acute ST elevation myocardial infarction were investigated. 54 patients underwent primary percutaneous coronary intervention and 97 patients were treated with thrombolytic therapy. The frequency of reperfusion arrythmias following revascularization procedures in the first 48 hours after admission was examined. The relation between reperfusion arrhythmias, ST segment regression, coronary artery patency, and infarct related artery documented by angiography were analyzed. Results. There was no statistically significant difference between the two groups in the frequency of reperfusion arrhythmias (P = 0.355). Although angiographic vessel patency was higher in patients undergoing percutaneous coronary intervention, there was no significant difference between the patency rates of each group with and without reperfusion arrythmias. Conclusion. Our study suggests that recorded arrhythmias following different revascularization procedures in acute ST elevation myocardial infarction may not always indicate vessel patency and reperfusion. Ongoing vascular occlusion and ischemia may lead to various arrhythmias which may not be distinguished from reperfusion arrhythmias.

Aim: The objective of this study was to compare the periprocedural and clinical outcomes after carotid artery stenting (CAS) with proximal protection devices versus with distal protection devices. Material and methods: Patients with internal carotid artery (ICA) stenosis undergoing CAS with cerebral embolic protection were randomly assigned to proximal balloon occlusion or distal filter protection. Adverse events were defined as death, major stroke, minor stroke, transient ischemic attack (TIA) and myocardial infarction (MI). Periprocedural and 30-day adverse events and ICA vasospasm rates were compared between the two embolic protection groups. Results: Eighty-eight consecutive patients were randomized: 48 patients with proximal protection (mean age 68.8 +/- 13.6, 66\% male) and 40 patients with a distal protection device (mean age 65.4 +/- 12.3
Subintimal angioplasty and stenting in chronic total femoropopliteal artery occlusions: Early- and mid-term outcomes

Background: This study was conducted to evaluate the initial and mid-term patency rates of chronic total femoropopliteal artery (FPA) occlusions treated by subintimal angioplasty (SIA) and stenting. Methods: From March 2010 to February 2013, 74 patients were included in the study. Seventy two patients with total occlusion of the FPA and good distal runoff (2 or 3 patent vessels) were treated with percutaneous SIA and stenting. All patients had severe claudication or critical limb ischemia. In all cases, the procedure was performed with a contralateral approach. Follow-up was done at 6 months with clinical evaluation and color-Doppler. If it was necessary, peripheric angiography was performed. Results: Immediate technical success was achieved in 72 (97\%) patients. Two (3\%) distal embolizations, 2 (3\%) groin hematomas, 1 (1\%) femoral pseudoaneurysm and 1 (1\%) rupture of the junction-external iliac-superficial femoral artery occurred. All of the complications were treated successfully. Total occlusion in 1 patient and critical occlusion in 3 patients were showed at the 6th month. Patency rate at the sixth month was 94\% with a stent length of 13.4 +/- 8.2 cm. Conclusions: Percutaneous SIA and stenting for chronic total of the FPA occlusion showed good initial and mid-term patency rates, with few periprocedural complications.
