Abstract:
Objectives: Percutaneous coronary intervention (PCI) of
total chronic total occlusion (CTO) still remains a major
challenge in interventional cardiology. There is only
insignificant knowledge reported in the literature about age
differences in CTO recanalization. We analyzed in this study
the issue of the impact of age on procedural characteristics,
complications and short-term outcome.
Methods: Between 2012-2016 we included 440 patients. They
underwent PCI for at least one CTO. Antegrade and
retrograde CTO techniques were applied. The retrograde
approach was used only after failed antegrade intervention.
Continuous data are presented as the mean ± standard
deviation; categorical data are presented as numbers and
percentages unless otherwise specified. We used Twosamplet-
t-test with equal variance to test the significant
differences of the variables between the two cohorts.
Results: Procedural success proved independently of age.
There was no significant interaction between age and
procedural success (p=0.5). Complication rates were low in
both groups (2.7% vs. 4%; p=0,4) with no difference in
statistical significance.
Conclusions: Our study suggests that in an aging society
patients with severe coronary artery disease and chronical
total occlusions an interventional therapy should be used
more intensively. It can be performed safe and feasible.
