Abstract 19227: Left Ventricular Lead Implantation for Cardiac Resynchronization Therapy is Facilitated by Three Dimensional Rotational Venography of the Coronary Sinus Tree

Cardiac resynchronization therapy (CRT) requires optimal visualization of the coronary sinus (CS), its tributaries and their threedimensional localization for successfull lead placement. Preoperative knowledge of the CS anatomy facilitates catheter-based intubation of the CS, target vein and lead selection and reduces the need for fluoroscopy, contrast medium and overall procedure time. 3-dimensional rotational angiography (3DRA) provides a new means of multiangle imaging of the CS tree that can be applied preoperatively in the cath lab. Our study aims to investigate the feasibility of preoperative rotational CS venography and its implications on CRT implantation procedures. For this purpose, CS-visualization for CRT implantation was done either conventionally with retrograde CS-venography and standard fluoroscopic views (SFV, n = 30), or with antegrade CS-imaging via contrast medium injection (15 ml) into the left coronary artery using 3DRA in the venous phase of contrast flow (3DRA, n = 30). 3DRA succes...
