Large left ventricular metastasis causing left ventricular outflow tract obstruction and haemolysis

Area of Science:

• Cardiology
• Oncology
• Medical Imaging

Background:

• Cardiac metastases are often clinically silent and underdiagnosed.
• Echocardiography screening is limited, typically reserved for patients receiving cardiotoxic chemotherapy.
• Advances in cancer therapies may alter the natural history of metastatic disease, potentially increasing recognition of rare presentations.

Observation:

• A solitary, large ventricular metastasis caused left ventricular outflow tract obstruction and hemodynamic compromise.
• The metastasis was a recurrence of soft-tissue fibrosarcoma, diagnosed 9 years after the primary tumor resection.
• This case represents a rare instance of a symptomatic ventricular metastasis without other signs of metastatic disease.

Findings:

• Echocardiographic imaging was crucial for diagnosing the ventricular metastasis.
• The metastasis led to significant left ventricular outflow tract obstruction.
• The patient's presentation was unusual due to the solitary, symptomatic nature of the cardiac metastasis.

Implications:

• Highlights the importance of considering cardiac metastasis in patients with unexplained hemodynamic compromise, even in the absence of widespread disease.
• Suggests that echocardiography may have a role in evaluating unexplained cardiac symptoms in cancer survivors.
• Underscores the evolving landscape of cancer metastasis with novel therapeutic agents potentially changing disease presentation and prognosis.
