“…The coiled design of this stent does not completely eliminate tissue prolapse or recoil and its relatively small radial strength has prompted its use after an aggressive predilatation. These latest unfavorable characteristics did not affect our procedural success that was possible in a larger number of lesions (97.9%) compared with previous studies [5,6,17,18].…”

Direct stenting (DS) was attempted in 99 coronary lesions in 94 patients while standard stenting (SS) was attempted in 113 lesions in 103 patients matched for clinical characteristics, stenosis type, and location and stent type. The angiographic result was also evaluated according to TIMI frame count method (TFC) before and after procedure. A clinical follow-up was performed 1 year after the procedure. Before the procedure, TIMI grade 3 flow was detected in 42 cases (42.4%), grade 2 in 40 cases (40.4%), grade 1 in 5 cases (5.1%), and grade 0 in 12 cases (12.1%) in the DS group; these data were similar in SS group. After the procedure, TIMI grade flow was 3 in 90 cases (92.8%) in DS group and in 87 (77.0%) in SS group (P < 0.005); grade 2 was observed in 7 case (7.2%) in DS group and in 25 (22.1%) in SS group (P < 0.005). Major adverse cardiac events during hospitalization and at follow-up were similar in two groups. Radiation exposure time and procedure costs per lesion were significantly reduced in DS group compared to SS group (10.1 +/- 8 min vs. 13.9 +/- 4.7 min, P < 0.001; and 1901 +/- 687 Euro vs. 2352 +/- 743 Euro, P < 0.001, respectively). This study confirms that, in selected patients, direct stenting is a safe and successful procedure, allowing a significant reduction in radiation exposure time and procedural costs compared to standard stenting technique. The angiographic success is confirmed by the improvement in TFC in all cases.

“…So far, it has been reported that the advantages of the direct stenting strategy mostly rely on cost and radiation exposure reduction [17,18], but no data have been reported on angiographic flow. The main finding of the present study is that direct stenting determines a significant improvement of angiographic flow than standard stenting.…”

“…On the other hand, there were only 3 patients (2%) in Group A who underwent direct stent implantation without predilation. Previous studies [25][26][27][28][29] have demonstrated that direct stenting without balloon predilation reduces the slow flow and no-reflow phenomena and therefore, direct stenting might have influenced the achievement of blush-3 in this study.…”

hrombus formation after plaque rupture is the cause of vessel occlusion in acute myocardial infarction (AMI) and early, complete revascularization can salvage myocardium at risk and improve survival. 1 Primary angioplasty and stent implantation are important therapeutic options 2,3 and are associated with a higher reperfusion rate than pharmacological therapy alone. 4 However, these procedures can involve mobilization of thrombus and atheroma elements, causing distal embolization, the no-reflow phenomenon and impairment of the microcirculation, which reduce the clinical benefit of primary angioplasty. [5][6][7][8][9][10] The recent development of many kinds of thrombectomy device has made it possible to aspirate and remove intracoronary thrombotic material.The purpose of the present study was to evaluate the effectiveness of pretreatment by thrombectomy on myocardial salvage after stent implantation in patients with AMI.

“…This observational study showed that direct stent implantation using a 5F guiding catheter and the transradial approach is feasible, safe, and effective, achieving a very low complication rate, almost zero. Other studies have already demonstrated that direct stent implantation without predilation is a safe and effective technique [7][8][9][10] , but the use of a 5F guiding catheter and the transradial approach has been demonstrated only in a series of patients selected with acute ischemic syndromes 11 .…”
