Impact of stent deployment pressure and poststenting dilatation on the outcome of elective percutaneous coronary intervention

Impact of stent deployment pressure and poststenting dilatation on the outcome of elective percutaneous coronary intervention Mahmoud K Nour Department of Critical Care Medicine, Faculty of Medicine, Cairo University, Giza, Cairo, Egypt Background: High-pressure stent deployment was proposed as a strategy that ensures complete stent apposition but its relation to outcome is markedly debated. Objective: To verify the influence of stent deployment pressure and poststenting dilatation on the outcome of percutaneous coronary intervention. Methods: We included 120 patients with single vessel coronary artery disease who were subjected to elective stenting. Patients were divided into two groups: group A, high deployment pressure ≥16 atm and group B, low deployment pressure 8–12 atm. Group B was subdivided into two subgroups according to whether patients underwent poststenting dilatation (subgroup B1) or not (subgroup B2). Clinical and angiographic 6-month follow-up was performed. Results: The mean stent deployment pressure was higher in group A compared to group B (19±3 vs 10±2, P
