Does computed tomography angiography (CTA) improve the visualisation of coronary venous anatomy compared to fluoroscopic angiography in patients planned for CRT implantation?
Pre-procedural CTA is technically feasible for visualising coronary venous anatomy and can facilitate CRT implantation planning by identifying relevant veins and anatomical anomalies.
Nguyên et al. (2018) conducted an observational in Heart failure requiring cardiac resynchronisation therapy (CRT) (n=18). Computed tomography angiography (CTA) vs. Intra-procedural fluoroscopic angiography (FA) was evaluated on Concordance of coronary venous anatomy visualization between CTA and FA. Pre-procedural computed tomography angiography successfully visualized 85% of coronary veins seen on fluoroscopic angiography and impacted the cardiac resynchronisation therapy implantation approach in a quarter of patients.
