INTRODUCTION
Pericardial synovial sarcoma is one of the rarest primary cardiac tumors, with a median overall survival of 27 months.1Surgical resection is the main factor associated with prolonged survival.2 Unfortunately operative guidelines have not been standardized given the rarity, heterogeneity, and anatomical complexity, including intramyocardial involvement and left-sided tumors.
Autotransplantation has been shown to be a feasible technique for complex, left-sided cardiac tumor resection.3 While rarely used for cardiac tumors, partial autotransplantation techniques offer left atrial access with decreased ischemic time.4-7 We present the second reported case of pericardial synovial sarcoma treated with modified autotransplantation and adjuvant radiation.
