Direct Repair of Localized Aortic Dissection with Critical Malperfusion of the Left Main Trunk

Abstract

Background: Localized aortic dissection on the left coronary cusp with critical malperfusion of the left main trunk (LMT) is rare and carries a high risk of death.

Case presentation: We report a case of a 48-year-old patient who developed localized aortic dissection of the left coronary cusp complicated by critical malperfusion of the LMT of the coronary artery. After percutaneous coronary intervention (PCI) for the LMT, a Koster–Collins-like direct repair of the localized aortic dissection was carried out by closure of the false channel using BioGlue (CyroLife, Inc., Kennesaw, GA, USA) with the reinforcement of double Teflon felt strips.

Conclusion: The aortic repair using a modified Koster–Collins technique was successful.
