Cardiac metastasis from a transitional cell carcinoma: a case report

Area of Science:

• Cardiology
• Oncology
• Pathophysiology

Background:

• Metastatic tumors to the heart are uncommon but can significantly impact cardiac function.
• Transitional cell carcinoma is a type of cancer that can rarely metastasize to the heart.

Observation:

• A patient presented with severe hypoxemia.
• Diagnostic imaging revealed a metastatic tumor within the right ventricle.
• The tumor's position, coupled with a patent foramen ovale, caused a right-to-left shunt.

Findings:

• The right ventricular tumor obstructed blood flow, leading to impaired oxygenation.
• The patent foramen ovale facilitated the right-to-left shunt, exacerbating hypoxemia.
• The patient's condition was attributed to metastatic transitional cell carcinoma.

Implications:

• This case underscores the importance of considering cardiac metastases in patients with unexplained hypoxemia and a history of cancer.
• Understanding the pathophysiology of cardiac metastases is crucial for timely diagnosis and management.
• Further research into the mechanisms and treatment of cardiac metastases is warranted.
