Expanding options for retrograde recanalisation of right coronary artery chronic total occlusions
Recanalising RCA CTOs can be challenging, but can also provide important clinical benefits. Having multiple crossing options is critical for high success rates. Consult this EuroIntervention Article on expanding options for retrograde recanalisation of right coronary artery chronic total occlusions by E. Brilakis.
The right coronary artery (RCA) is the most common target vessel for chronic total occlusion (CTO) percutaneous coronary intervention (PCI), accounting for 44% of target lesions in the multicentre CTO registry in Japan (J-CTO)1, 50% in the European Registry of Chronic Total Occlusion (ERCTO)2, and 59% in the Prospective Global Registry for the Study of Chronic Total Occlusion Intervention (Progress CTO)3. The exact reasons underlying this high prevalence are unclear. Possible contributing factors may include the long length that the RCA runs in the atrioventricular groove before it bifurcates into the posterior descending and posterolateral arteries. The poor long-term patency of saphenous vein grafts4 in contrast to the excellent patency of internal mammary grafts also results in the native occluded vessel becoming clinically relevant following bypass surgery5.
