Use of hemostasis pad that accelerates blood clotting has become an effective alternative. The ezClot pad is a new product that uses chitosan, a deacetylated complex carbohydrate derived from the naturally occurring substance chitin. The positively charged chitosan molecules attract the negatively charged blood cells and platelets, thus promoting clots. The ability to hemostasis of chitosan has been proven with the HemCon® pad (HemCon Medical Technologies, Inc., Portland, OR, USA). This study was designed to confirm the safety and efficacy of the ezClot pad in patients undergoing percutaneous procedures with arterial approach. Two cohorts will be included in this study: transradial and transfemoral cohort. Among the transfemoral cohort, the safety and efficacy of the ezClot pad will be compared with the BloodSTOP® pad (LifeScience PLUS, Palo Alto, CA, USA). The BloodSTOP® pad is an etherized and oxidized regenerated cellulose matrix that achieves hemostasis by activating the intrinsic coagulation pathway.
