Background: The safety and feasibility of ambulatory PCI has been demonstrated in selected patients with "simple" lesions, but it is not well known whether it could be applied in more "complex" scenarios.
Methods: Main objective is to assess the feasibility and safety of ambulatory complex PCI. Prospective multicentre registry of 1047 consecutive patients planned for ambulatory trans-radial PCI. Outcomes in patients with "complex angioplasty" (CA group: 313 (30%)) were analysed and compared with those of "simple angioplasty" (SA group: 734, 70%). The feasibility (% of patients finally discharged) and safety (MACE at 24 h and at 1 month) were compared between groups. We also analyse admissions, visits to the emergency department and minor vascular complications.
Results: Feasibility was higher for SA (80.6% vs. 63.6%, OR 1.89, 95% CI 1.52-2.35, p < 0.001). Ambulatory PCI was very safe in both groups. In CA no MACE occurred at 24 h (vs. 0.17% SA) or 30 days (vs. 0.68% in SA). There were also no differences in re-admissions, visits to the emergency department or minor vascular complications (there was a non-significant tendency to higher rate of radial occlusion at 1 month in the CA group, 5.5% vs. 2.7%, p: 0.07).
Conclusions: The feasibility of ambulatory PCI in selected patients with complex lesions is lower than in simple lesions, however when it is possible, it is as safe as in selected patients with simple lesions.
