Key result
Transmitral prolapse of an 8.5 cm left atrial myxoma causes severe PH and HF.
Why the study?
Particularly large cardiac myxomas can cause mass effect and marked hemodynamic derangement, including secondary pulmonary hypertension, which complicates surgical management.
Population
41-year-old man presenting with a cardiac myxoma and severe pulmonary hypertension
Design
Case report

Prompt surgical resection remains standard for symptomatic myxomas; leaves open evidence-based thresholds for asymptomatic large tumors.
Case Report (n=1)
This case highlights the presentation of a giant left atrial myxoma causing severe pulmonary hypertension and mass effect, requiring careful hemodynamic optimization prior to surgical removal.
Shaikh et al. (2024) conducted a case report in Left atrial myxoma with severe pulmonary hypertension (n=1). Left atrial myxoma was evaluated. A 41-year-old man presented with severe pulmonary hypertension and heart failure symptoms caused by an 8.5 cm left atrial myxoma prolapsing through the mitral valve.
