Key result
Transvenous endocardial biopsy fails to diagnose cardiac angiosarcoma due to overlying thrombus, necessitating metastasis biopsy.

Negative endocardial biopsy may miss cardiac angiosarcoma; this case leaves open optimal diagnostic strategies pending validation.

Transvenous endocardial biopsy of a cardiac angiosarcoma may yield false-negative results (e.g., organized thrombus), necessitating further biopsy of suspected metastases for definitive diagnosis.
Nitta et al. (1998) conducted a case report in Primary cardiac angiosarcoma (n=1). Transvenous endocardial tumor biopsy was evaluated on Tumor diagnosis. Transvenous endocardial tumor biopsy failed to diagnose a primary cardiac angiosarcoma because the endocardium was covered with organized thrombus, necessitating incisional biopsy of a metastasis.
