Key result
Post-termination surgical resection of left atrial myxoma yields favorable recovery with no recurrence at 10 months.
Why the study?
Cardiac myxoma during pregnancy is exceptionally rare and may present with systemic embolisation, but bilateral renal infarction as an initial manifestation is uncommon.
Case Report (n=1)
This case highlights that bilateral renal infarction can be an uncommon initial manifestation of cardiac myxoma during early pregnancy, necessitating multidisciplinary management.
Supports cardiac source evaluation in pregnant patients with visceral infarction; extends sparse case evidence on myxoma management but leaves open generalizability.
Cardiac myxoma during pregnancy is exceptionally rare and may present with systemic embolisation. A 25-year-old woman at six weeks and five days of gestation presented with persistent central abdominal pain radiating to both flanks. Laboratory investigations showed elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH) levels, while renal function and urinalysis were unremarkable. Non-contrast abdominal magnetic resonance imaging (MRI) demonstrated bilateral renal infarctions. Transthoracic echocardiography subsequently identified a large, mobile, pedunculated left atrial mass, and cardiovascular magnetic resonance (CMR) showed an atypical attachment to the Coumadin ridge. Following multidisciplinary counselling regarding maternal and foetal risks, the patient chose termination of pregnancy followed by surgical resection. Histopathological examination confirmed a left atrial myxoma. The postoperative course was favourable, with preserved renal function and no tumour recurrence on 10-month echocardiographic follow-up. This case highlights bilateral renal infarction as an uncommon initial manifestation of cardiac myxoma and the importance of considering a cardiac embolic source in unexplained visceral infarction during pregnancy.

Min et al. (2026) conducted a case report in Left atrial myxoma during early pregnancy (n=1). Surgical resection following termination of pregnancy was evaluated on Clinical outcome and tumor recurrence. Surgical resection of a left atrial myxoma following termination of pregnancy resulted in a favorable postoperative course with preserved renal function and no tumor recurrence at 10 months.
