Neovascularization in left atrial myxoma

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Cardiac Imaging

Background:

• Left atrial masses require thorough evaluation to differentiate between neoplastic and non-neoplastic etiologies.
• Coronary artery disease assessment is standard in patients with cardiac masses, particularly when symptoms overlap.

Observation:

• A patient with a left atrial mass underwent coronary angiography for coronary artery disease evaluation.
• The angiography revealed an anomalous, tortuous vascular structure extending from the left circumflex coronary artery to the left atrial mass.

Findings:

• The vascular structure was suggestive of neovascularization supplying the left atrial tumor.
• This finding indicates a potential vascular tumor or a reactive neovascular response within the mass.

Implications:

• Preoperative coronary angiography is crucial for identifying the specific feeding vessels of left atrial masses.
• This information aids in surgical planning and risk assessment for masses supplied by coronary arteries.
• Coronary angiography can reveal unexpected vascular abnormalities associated with cardiac tumors.
