ABSTRACT
OBJECTIVES:
This registry evaluated the current trends and outcomes associated with retrograde percutaneous coronary intervention (PCI) for chronic total occlusion (CTO).BACKGROUND:
Since its introduction, several techniques and technologies have been introduced for retrograde PCI for CTO.METHODS:
Eight hundred and one patients who underwent retrograde PCI for CTO in 28 Japanese centers between January 2009 and December 2010 were enrolled in this registry.RESULTS:
Overall procedural and clinical success rates were 84.8 and 83.8%, respectively, of which, retrograde procedures accounted for 71.2 and 70.3%, respectively. The use of channel dilators increased in 2010 compared to that in 2009 (36 vs. 95.3%, P < 0.0001), attributed improving collateral channel crossing using a wire and catheter (70.6% vs. 81.1%, P = 0.0005) and increased availability of epicardial channels (27.6% vs. 36.9%). The use of the reverse controlled antegrade and retrograde tracking technique also increased (41.9 vs. 66.5%). Although these changes decreased procedure time (203.3 min vs. 187.9 min, P = 0.024), they did not significantly improve overall procedural success rate (84.1% vs. 85.3%, P = 0.63). Multivariate analysis identified age 65 years or more and lesion calcification as unfavorable factors and the use of a channel dilator as a favorable factor for retrograde procedural success.CONCLUSIONS:
Increased availability of channel dilators has altered strategies for retrograde PCI for CTO. However, retrograde PCI for CTO could be improved by overcoming its main obstacle of severe calcification.Palavras-chave
