Successful Commando procedure using the superior transseptal approach in a high-risk case.

Background: The Commando procedure, which involves replacement of both the aortic and mitral valves along with reconstruction of the intervalvular fibrous body, is technically demanding. Commando procedure typically performed via an incision extending from the ascending aorta to the roof of the left atrium. However, in patients with extensive adhesions due to prior cardiac surgery, adding a superior transseptal incision can provide good exposure and reduce the risk of surrounding tissue injury.

Case Presentation: A 48-year-old woman with end-stage kidney disease on dialysis, diabetes mellitus, bilateral leg amputations from critical limb ischemia, and chronic steroid use presented in cardiogenic and septic shock. The patient had undergone mitral valve repair and coronary bypass surgery using saphenous vein grafts. Echocardiography revealed severe aortic and mitral valves stenosis. Given the extensive adhesions and complex anatomy, the Commando procedure was performed using a superior transseptal approach. A 25-mm MITRIS was implanted in the mitral position, and a 25-mm INSPIRIS in the aortic position. A tailored oval-shaped patch made of bovine pericardium was used to reconstruct the intervalvular fibrous body. The patient recovered without major complications.

Conclusion: The superior transseptal approach provided excellent exposure and a stable operative field, facilitating standardized surgical maneuvers throughout the Commando procedure.
