Key result
Valve-sparing transseptal excision of left atrial myxoma reverses functional mitral stenosis, cutting transmitral gradient ~85%.
Why the study?
Left atrial myxomas are rare, potentially life-threatening benign cardiac tumors requiring early surgical excision to prevent embolic events, obstruction, and sudden death.
Population
One 72-year-old Turkish woman with a large left atrial mass and exertional dyspnea and palpitations

May warrant valve-sparing transseptal excision for LA myxoma with functional MS; leaves open broader adoption pending larger series.

Valve-sparing transseptal excision of a large left atrial myxoma rapidly reverses functional mitral stenosis and normalizes transmitral hemodynamics.
Bozkurt et al. (2026) conducted a case report in Left atrial myxoma with functional mitral stenosis (n=1). Valve-sparing transseptal excision vs. Preoperative baseline was evaluated on Mean transmitral gradient. Valve-sparing transseptal excision of a large left atrial myxoma rapidly reversed functional mitral stenosis, reducing the mean transmitral gradient from 9 mmHg to 1.3-1.4 mmHg.
