Limitations

  • Small sample size inherent to a case report of two patients, limiting generalizability.

Cite This Study

Lizwan et al. (2026) conducted a case report in Calcified left atrial myxoma (n=2). Surgical excision was evaluated. Surgical excision of complex, calcified left atrial myxomas encroaching on the mitral annulus resulted in contrasting outcomes in two patients, ranging from successful repair to fatal multiorgan failure.
