On August 1st, 2nd and 3rd, São Paulo hosted SOLACI-SBHCI 2019 . It was great to see many participants of the CTO Registry in important activities on current issues in the treatment of CTO. Attached is a picture with part of the group who attended the meeting on Saturday. The conversations and discussions have been very helpful, so we can continue improving the quality of LATAM SBHCI CTO Registry. Below are some comments on topics covered during the Congress and related to the methodology and data collection.
