Overview of Cardiac Tumors
Benign Tumors
Cardiac myxomas
Frequency: 30% of benign tumors
Location: left atrium (75%), right atrium (23%), ventricles (2%)
presentation: intracardic obstruction, embolization, constitutional symptoms (fever, weight loss, fatigue, arthralgias, rash)
Preferred imaging modality: 2D echo- TTE is adequate
{{#ev:youtube|SD2LrK1mdic}} LA myxoma
Lipomas
Frequency: 10% of benign tumors
Location: Left ventricle, right atrium, interarterial septum
size: 1-15cm
Preferred imaging modality: MRI
Rhabdomyomas
Frequency: 6% of benign cardiac tumors
Location: ventricles and atria (pedunculated mass), within septal myocardium
presentation: heart block, SVT, ventricular tachycardia, sudden death
demographic: 75% occur in children (<1 yo)
Fibromas
Location: usually within the myocardium of the left ventricle, anterior free wall, interventricular septum
size: 3-10cm
presentation:
demographic: rarely in adults, mostly in children
Papillary fibroelastoma
Frequency: 8% of benign tumors
Size: 0.5 - 2.0 cm
Location: mitral valve (most commonly), aortic valce, endocardial surfaces
Demographic: 60 yo (average age)
Presentation: embolization
Hemangiomas
Malignant Tumors
Angiosarcoma
Frequency: 30% of malignant cardiac tumors
Leiomyosarcoma
Rhabdomycosarcoma
Frequency: 10% of primary cardiac sarcoma. Most common cardiac tumor in children
Lymphoma
Fequency: 5% of primary malignant cardiac tumors
