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,
