Conclusion

• During the first 9 years the club made huge

progress in gaining new experts, accepting

more severe CTO-cases increasing success

rate, most likely by watching, teaching and

adopting accepted techniques (convergence

of interventional aproach).

• Registry and monitoring confirms high

credibility of our data

Credibility check of the online

EuroCTO-registry 2008-14

• Logical checks on data ( predefined value

ranges)

• Logical consistency-tests with respect to

other data fields

• Automatic warnings when data are missing

2015 and on:

10 % reabstraction of CTO records

(n = 250/ year), masked and

reviewed by a second abstractor

At random : „ your patient was

selected for monitoring“

Automatic export of registry parameters

9

parameters to be checked

by reviewer

Results of Monitoring (n=202)

Successful wire 2015

Did Monitoring influence data?

Monitored Registry

• Only few entries with overt disagreement

• No relevant change in grading of severity

i.e.high credibility of data

• Good source for publications of the clubs

experience, open to all members
