Background:
Intravenous leiomyomatosis (IVL) is a rare benign uterine growth that extends into the venous system.
Case Summary:
This case describes a 48-year-old female who presented with 1 month of chest pain and dyspnea on exertion. She was found to have a right atrial mass that transiently crossed into the right ventricle with associated moderate tricuspid regurgitation. Computed tomography revealed a uterine mass with contiguous intravascular extension through the inferior vena cava terminating in the right atrium.
Discussion:
IVL may present as syncope, dyspnea, and right-sided heart failure. IVL should be on the differential for premenopausal women who present with heart failure symptoms and are found to have an intracardiac mass.
Take-Home Messages:
This case of symptomatic tricuspid valve obstruction due to IVL illustrates the importance of maintaining preload. Chest and abdominal imaging may be necessary to identify the source of the mass and ensure appropriate surgical planning.
