Key result
Commando procedure enables radical resection with negative margins for recurrent cardiac intimal sarcoma.
Why the study?
Primary cardiac intimal sarcoma is an extremely rare, high-grade malignancy characterized by rapid progression and high early recurrence rates.
Is the Commando procedure a viable surgical option for radical resection of recurrent cardiac intimal sarcoma in a young adult?

Is the Commando procedure a viable surgical option for radical resection of recurrent cardiac intimal sarcoma in a young adult?
The Commando procedure, involving double valve replacement and intervalvular fibrosa reconstruction, is a viable aggressive surgical option to achieve negative margins in young patients with recurrent cardiac intimal sarcoma.

Supports Commando procedure feasibility for negative margins in recurrent cardiac intimal sarcoma; leaves open its role pending prospective data.
Primary cardiac intimal sarcoma is an extremely rare, high-grade malignancy characterized by rapid progression and high early recurrence rates. We report the case of a 28-year-old male who underwent emergency resection for a large left atrial intimal sarcoma (10 × 8 cm). Follow-up imaging at 6 months revealed a 15-mm recurrent tumor infiltrating the left atrial septum, despite an initially stable recovery. We prioritized radical resection over surgical risk, given the patient’s youth and the aggressive behavior of the tumor. Therefore, a “Commando” procedure consisting of radical tumor resection, double valve replacement, and reconstruction of the intervalvular fibrosa using the Manouguian technique was performed. Histopathological examination confirmed recurrent intimal sarcoma with negative surgical margins. Despite its high invasiveness, the Commando procedure is viable for primary treatment for recurrent cardiac intimal sarcomas in young patients. Aggressive surgical reconstruction remains the only viable option to improve the prognosis of this otherwise fatal malignancy.

Komagamine et al. (2026) conducted a case report in Recurrent cardiac intimal sarcoma (n=1). Commando procedure (radical tumor resection, double valve replacement, and reconstruction of the intervalvular fibrosa) was evaluated on Histopathological confirmation of surgical margins. The Commando procedure achieved radical resection with negative surgical margins for a recurrent cardiac intimal sarcoma in a 28-year-old male.
