Official title

Arterial Versus Venous Activated Clotting Time Measurements During Atrial Fibrillation Ablations

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Activated clotting times (ACTs) are routinely measured throughout atrial fibrillation ablations to monitor anticoagulation prior to and after heparin administration. Routinely, ACTs are obtained from an arterial line established prior to heparin administration. With technological advances, the cardiac intervention team is interested in eliminating the need for arterial lines for noninvasive monitoring devices; eliminating arterial lines could decrease the risk of bleeding, infection, and pain. Since procedural access requires femoral vein catheterization, obtaining ACTs through the venous sheath would not pose additional risks to the patient. In this study it proposed to draw paired arterial and venous ACT samples in ablation procedures to compare the agreement between venous and arterial ACTs for adequate patient treatment planning.
