Actual outpatient PTCA: results of the OUTCLAS pilot study

This study tested the safety and feasibility of coronary angioplasty on an outpatient basis. The purpose of this approach includes cost-effectiveness and patient comfort. Included were 159 patients treated with balloon angioplasty or intracoronary stent placement, all performed via the radial artery with 6 French guiding catheters. Patients were selected for same-day discharge based on the absence of any adverse predictor for subacute occlusion or unfavorable clinical outcome during the first 24 hr after successful PTCA. One hundred and six (66%) patients were discharged 4-6 hr after PTCA. Stents were used in 40% of patients. There were no cardiac or vascular complications. We conclude that outpatient PTCA, performed via the radial artery, is both safe and feasible in a large part of a routine PTCA population.
