Introduction: surgery, balloon angioplasty, or endovascular stent placement are common approaches for aortic coarctation. Although percutaneous methods have historically proven safe, consensus on their efficacy and complications is lacking. Objective: to describe the experience of both percutaneous techniques in a highly complex center without attempting to establish a direct comparison. Method: a retrospective study in Colombia (2011-2022) evaluated aortic coarctation patients, analyzing outcomes of balloon angioplasty or stent placement. Data on interventions, complications, and follow-up were analyzed for immediate, short-term, medium-term, and long-term periods. Results: evaluation of 61 patients (37 native, 24 recoarctation), mean age 13 (1-17). Balloon angioplasty (33 patients) and endovascular stent placement (28 patients). Success rates were stratified by coarctation type, pre- and post-angioplasty gradient. Balloon angioplasty: 86.7% success (native), 88.8% (recoarctation). Stent placement: 81.8% success (native), 83.3% (recoarctation). Most common complication was hypertension, with an incidence of 37.7%, higher in the stent group. Conclusions: both techniques proved safe, with balloon angioplasty showing a high success rate. Long-term complications were minimal but being a single-center study with heterogeneous ages limits generalization, emphasizing the need for larger prospective studies.
