About

Arterial access is the key step during the endovascular treatment of cardiovascular diseases. This study was designed to confirm the safety and efficacy of the hemostasis pad using chitosan 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. The hypothesis will be tested among the transradial cohort that the combined use of a hemostasis pad and a compression device is superior to that of a compression device only in terms of hemostasis in patients who underwent tranradial coronary procedures.

Full description

Arterial access is the key step during the endovascular treatment of cardiovascular diseases. However, failure in hemostasis of the arterial access sites is associated with high risk of complications such as bleeding, pseudoaneurysm, and arteriovenous fistula. Major bleeding events after percutaneous coronary intervention has been shown be associated with poor short-term as well as long-term prognosis. Thus, there have been a variety of approaches to quickly and effectively achieve hemostasis of the puncture site. The traditional method was to apply manual compression followed by simple dressing directly on the puncture site. Despite a long history and economic advantage, this method required prolonged hemostasis time, substantial efforts by trained practitioner, and patients' discomfort.

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.

Transradial approach is increasing used during coronary procedures. The most important benefit of transradial approach compared to transfemoral approach is low risk of major bleeding. Widely used method for hemostasis of radial puncture sites were manual or device-assisted compression. There is yet only a limited data regarding the use of hemostasis pad after transradial approach. The hypothesis will be tested in the transradial cohort that the combined use of a hemostasis pad and a compression device is superior to that of a compression device only in terms of hemostasis in patients who underwent transradial coronary procedures.
