Why the study?

Cystic myxoma is a rare variant of cardiac myxoma with few cases reported, and its unique anatomical and hemodynamic features are not well described.

Population

54-year-old woman with exertional dyspnea, chest tightness, and intermittent dizziness

Design

Case report

Key result

Surgical excision of a rare balloon-like cystic cardiac myxoma resulted in complete resolution of the mass and normal mitral valve function, with no tumor recurrence at one-year follow-up.

Overview

Supports surgical excision for rare cystic myxomas; hypothesis-generating for multimodality imaging and long-term outcomes.

Key Points

To describe the clinical presentation, hemodynamic characteristics, and surgical findings of a rare balloon-like cystic cardiac myxoma mimicking a blood-filled cyst.
Evaluated a 54-year-old woman presenting with exertional dyspnea, chest tightness, and dizziness using ECG, laboratory testing, transthoracic echocardiography, contrast echocardiography, and transesophageal echocardiography.
Performed surgical resection with intraoperative verification of lesion flow dynamics using cardioplegic solution delivery.
Echocardiography revealed a balloon-like cystic mass in the left atrium with iso-myocardial contrast enhancement mimicking a blood-filled cyst.
Transesophageal echocardiography and intraoperative cardioplegia administration confirmed a distinct arterial inflow at the cyst base and an outflow orifice, leading to successful tumor resection.

Case Report (n=1)

Multicenter

Structured PICO

Population

A 54-year-old woman presenting with exertional dyspnea and chest tightness who was diagnosed with a rare balloon-like cystic cardiac myxoma.

Intervention

Surgical resection

Outcome

Successful resection and histopathological confirmation

This case highlights a rare balloon-like cystic variant of cardiac myxoma that mimics a blood-filled cyst, demonstrating the utility of multimodality echocardiography in its diagnosis.

Limitations

Absence of cardiac magnetic resonance (CMR) imaging for further tissue characterization and preoperative evaluation.
