Percutaneous axillary access for large-bore arteriotomy: A step-by-step guide.

The last decade has witnessed a tremendous growth in the type and complexity of transcatheter cardiovascular interventions that require large-bore access. While the common femoral artery has become the main route for these interventions, sizable cohorts of patients are unsuitable for transfemoral access due to vascular disease or small vessel caliber. Percutaneous axillary access has emerged as a feasible alternative in these patients. We provide a step-by-step guide for transaxillary large-bore access and closure for patients requiring transcatheter interventions.
