Each year at the Society for Cardiovascular Angiography & Interventions (SCAI) Annual Scientific Sessions meeting, collaborative think tanks involving interventional cardiologists, administrative partners, and members of industry are convened for each SCAI clinical practice area to discuss topics of interest to the group.

This document presents the proceedings of the coronary, structural, peripheral, and congenital think tank sessions at SCAI 2019:

1. Coronary: How should maintenance of skill/competency programming for less frequently used, but critical technologies (atherectomy, mechanical support, PFO closure, etc.) be developed?
2. Structural: Should training in SHD be formalized and standardized? 
3. Peripheral: Should SCAI support a comprehensive critical limb ischemia (CLI) vascular team model?
4. Congenital: Training and credentialing in CHD
