TCT-547 Long term outcomes of percutaneous lower- extremity arterial interventions with balloon angioplasty versus atherectomy- propensity score matched registry

The atherosclerosis plaques have different morphology from soft neointimal plaques to hard calcified lesions. Therefore, we sought to evaluate the efficacy of percutaneous balloon angioplasty (PTA) versus atherectomy (AT) endovascular revascularization which type was attuned by operator. Between
