Inserting Catheter Into Femoral Artery
Inserting a catheter into the femoral artery is the initial step of the Transcatheter Aortic Valve Replacement (TAVR) procedure. This catheter will serve as the access point to reach the heart. This task involves carefully and aseptically inserting the catheter under fluoroscopic guidance. The desired result is a successful and safe insertion of the catheter into the femoral artery. Challenges may include identifying the correct insertion point, ensuring aseptic technique, and managing potential complications such as bleeding or arterial dissection. The required resources for this task are sterile catheters, fluoroscopic imaging equipment, and communication tools.
Advancing Catheter to Heart
Advancing the catheter to the heart is a critical step in the Transcatheter Aortic Valve Replacement (TAVR) procedure. It requires precise manipulation and fluoroscopic guidance to navigate through the vascular system. This task aims to ensure the safe and accurate advancement of the catheter to the heart. Challenges may include navigating through complex vascular anatomy, avoiding vessel damage, and maintaining continuous fluoroscopic visualization.
