Key Points

  • This research aims to evaluate the effectiveness of a dual-lumen microcatheter in decompressing false lumen hematomas during coronary dissections.
  • Utilized a dual-lumen microcatheter placed in the false dissection lumen.
  • Applied negative pressure to facilitate hematoma decompression.
  • Enabled wiring of the true lumen for further percutaneous intervention.
  • Successfully decompressed the false lumen hematoma.
  • Improved access to the true lumen for percutaneous management.

Abstract

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.
