Background: Chronic
total occlusion (CTO) intervention is still challenging because of the limited
procedural success rate and higher recurrence. It is not clear whether the peri-procedural
myocardial infarction (P-MI) will significantly impact on angiographic and clinical
outcomes following CTO intervention.
Methods:
A total of 131 consecutive pts underwent CTO intervention were divided into P-MI
(n=12) and control group (n=119). Six-month angiographic and twelve-month clinical
outcomes were compared between the two groups. Results: The
baseline clinical characteristics were balanced between the two groups except more elderly (66.1±13.0 vs.
60.1±9.4 p=0.034) in the P-MI group. There were higher incidence of perforation
(15.3% vs. 0.7%, p=0.0005), dissection (46.1% vs.18.1%, p=0.018), any hematoma
and acute renal failure in the P-MI group. Angiographic outcomes at 6 months
were not different between the two groups. However, the incidence of total
death, any myocardial infarction (MI) and target vessel revascularization
(TVR)-major adverse cardiac events (MACE) were higher in the P-MI group at 24
months (Table). Conclusions:
P-MI
following CTO intervention was associated with higher 2-year mortality, any MI and TVR-MACE.
Careful procedure to minimize P-MI will be warranted to get optimal CTO
intervention outcomes. Figures and tables from this article: Copyright © 2013 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.
