Key result
Intracardiac leiomyomatosis linked to sudden death from RV failure following tumor embolization and PA occlusion.
Why the study?
Sudden death resulting from intracardiac leiomyomatosis is rare and not well characterized.
Intracardiac leiomyomatosis can rarely present as sudden death due to right heart failure from pulmonary artery occlusion.

Alerts clinicians to rare venous tumor embolization in unexplained sudden right heart failure; case reports leave open true incidence and prevention strategies.
Shi et al. (2018) studied this question. Intracardiac leiomyomatosis extending from the broad ligament caused sudden death in a 50-year-old woman due to right heart failure from tumor embolization and pulmonary artery occlusion.
