We studied the use of minor and major recurrence classifications with regard to observer variability, which directly affects validity of these terms as outcome measures. Recurrences at the time of a three to six month follow-up angiogram were assessed independently by two experienced observers in 83 cases. Intra- and interobserver concordance is approximately 90% for assessment of minor and major recurrence.
