Novel Use of Dual-Lumen Microcatheter for False Lumen Hematoma Decompression

Coronary dissection regardless of mechanism can be fatal and difficult to manage given size differences of the true and false lumen. Use of a dual-lumen microcatheter placed into the false dissection lumen with negative pressure applied can decompress the hematoma and enable wiring of the true lumen for percutaneous management.
