Overview

Surgery

Emergent CABG should be considered for patients with left main dissections, extensive dissections involving proximal arteries, or in patients in whom PCI failed or who are not anatomically suitable for PCI. Although many of this operations have been performed in case of emergency, good early outcomes following CABG have been reported in small observational studies.[1] [2] [3] Early graft failure was reported as 6% in a 20 patients series. [2] [3] However long term results of CABG showed lower graft patency (27%) in a small series which is because of spontaneous arterial healing lead to competitive flow and graft thrombosis. [4]


Indications for surgical revascularization (CABG)[5] include:

  • Multivessel involvement
  • Left main coronary artery involvement
  • Progression/worsening of dissection so long as there is a distal target
  • Significant narrowing of the arterial lumen
  • Refractory or recurrent myocardial ischemia

In the event of severe refractory heart failure, heart transplantation may be considered.
