Visualisation of coronary venous anatomy by computed tomography angiography prior to cardiac resynchronisation therapy implantation.

ABSTRACT:

Background

The purpose of this study was to illustrate the additive value of computed tomography angiography (CTA) for visualisation of the coronary venous anatomy prior to cardiac resynchronisation therapy (CRT) implantation.

Methods

Eighteen patients planned for CRT implantation were prospectively included. A specific CTA protocol designed for visualisation of the coronary veins was carried out on a third-generation dual-source CT platform. Coronary veins were semi-automatically segmented to construct a 3D model. CTA-derived coronary venous anatomy was compared with intra-procedural fluoroscopic angiography (FA) in right and left anterior oblique views.

Results

Coronary venous CTA was successfully performed in all 18 patients. CRT implantation and FA were performed
