Key result
Surgical resection of a mitral valve myxoma in a 32-year-old man presenting with a transient ischemic attack resulted in complete symptom resolution and no recurrence over 5 years of surveillance.
Why the study?
Cardiac myxomas rarely attach to the mitral valve, with just over 30 cases reported, warranting a review of their diagnosis and surgical management.
Case Report (n=1)
This case report highlights the rare presentation of a mitral valve myxoma causing a TIA in a young patient, successfully managed with surgical resection and valve repair.
May support resection for rare mitral valve myxoma with TIA; single case leaves open need for larger series on recurrence and surveillance.
BACKGROUND: Myxomas account for approximately half of all primary cardiac neoplasms. Most occur in the left atrium and only rarely are attached to the mitral valve, with just over 30 such cases reported in the literature. These neoplasms can manifest with a combination of obstruction of blood flow, systemic embolization, and constitutional symptoms. CASE DESCRIPTION: We present a case of a 32-year-old African American man presenting at an emergency department with symptoms of a transient ischemic attack. Transesophageal echocardiography identified a mass originating from the posterior leaflet of the mitral valve. The mass was surgically resected and histologically classified as a myxoma. He remained asymptomatic during the course of 5-year surveillance. CONCLUSIONS: Few similar cases have been described in the literature. Here we present a review of the diagnosis and surgical management of this rare presentation for mitral valve myxoma.

Grubb et al. (2018) conducted a case report in Mitral valve myxoma (n=1). Surgical resection was evaluated on Symptom resolution and tumor recurrence. Surgical resection of a mitral valve myxoma in a 32-year-old man presenting with a transient ischemic attack resulted in complete symptom resolution and no recurrence over 5 years of surveillance.
