Study Notes
Cardiac Tumors Overview
- Cardiac tumors are categorized into primary and secondary types.
- Secondary cardiac tumors are more common, originating from distant sites (e.g., lung, breast, kidneys) and infiltrating heart tissues.
- Primary cardiac tumors are rare and form from cardiac or mesenchymal tissue, primarily myxomas and rhabdomyomas.
Secondary Cardiac Tumors
- Lung cancer is the most common secondary tumor type affecting the heart.
- Lymphoma follows, with Non-Hodgkin's lymphoma being more prevalent than Hodgkin's.
- Other common cancers include breast cancer, leukemia, melanoma, hepatocellular carcinoma, and colorectal carcinoma.
- Secondary tumors typically invade the pericardium (most common infiltration site) and myocardium.
Pericardial Invasion Effects
- Tumors can cause pericarditis, leading to inflammation and increased serous fluid production.
- Accumulation of fluid may result in pericardial effusion, potentially progressing to cardiac tamponade.
- Cardiac tamponade obstructs heart expansion, risking hemodynamic instability.
Myocardial Invasion Effects
- Invasive tumors lead to myocarditis, which can progress to cardiomyopathy, often dilated cardiomyopathy.
- Myocardium dysfunction can occur due to inflammation and prolonged damage.
Primary Cardiac Tumors
- Primarily consists of myxomas (common in adults) and rhabdomyomas (common in children).
- Myxomas form a gelatinous mass from mesenchymal tissue of the interatrial septum, potentially blocking the mitral valve.
Myxoma Complications
- Mitral valve obstruction can lead to decreased ventricular filling, reduced stroke volume, and subsequently lower cardiac output.
- Symptoms include syncope (loss of consciousness due to cerebral hypoperfusion), exertional dyspnea, pulmonary edema, and paroxysmal nocturnal dyspnea.
- Pieces of myxoma can embolize to cause strokes (left-sided emboli) or pulmonary emboli (right-sided emboli).
- Increased levels of interleukin-6 from myxomas can cause fever, weight loss, and malaise.
Examination and Diagnosis
- Diagnosis usually involves echocardiography.
- Transesophageal echocardiogram (TEE) is preferred for visualizing atrial masses effectively.
Treatment
- Surgical resection of myxomas is curative due to their benign nature.
- Rhabdomyomas commonly associate with tuberous sclerosis and appear as hamartomas in cardiac and other tissues.
- Diagnosis of rhabdomyoma also utilizes echocardiography for visual confirmation.
Additional Information
- Myxomas can produce a characteristic "tumor plop" murmur due to obstruction during diastole.
- Evaluations for associated tumors in patients with rhabdomyomas should include screenings for brain, kidney, eye, skin, and lung lesions.### Cardiac Tumors in Patients
- Transesophageal echocardiography (TEE) is preferred for imaging in this patient population.
- Tumors in this context are typically unpedunculated and usually found within ventricular walls rather than atria.
- Genetic testing, including screening for TSC1 and TSC2 genes associated with tuberous sclerosis, can identify potential causes of cardiac tumors.
Tuberous Sclerosis and Cardiac Masses
- Tuberous sclerosis can lead to the development of hematomas and other tumor types.
- When encountering a cardiac mass, ruling out tuberous sclerosis is essential.
- If the mass is benign and asymptomatic, observation may be sufficient.
Symptomatic Patients
- Patients may develop symptoms if the tumor obstructs the left ventricular outflow tract or leads to heart failure.
- Surgical resection is recommended for symptomatic patients to alleviate complications.
Cardiac Tumors Overview
- Cardiac tumors are classified as primary (rare) or secondary (more common) types.
- Secondary tumors often originate from distant sites like lungs, breasts, and kidneys, infiltrating heart tissues.

- Tumors can cause pericarditis, which leads to inflammation and excess serous fluid production.
- Fluid accumulation results in pericardial effusion, which can progress to cardiac tamponade.
- Cardiac tamponade obstructs heart expansion, posing a risk of hemodynamic instability.
Myocardial Invasion Effects

- Mitral valve obstruction from myxomas decreases ventricular filling, resulting in lower stroke volume and cardiac output.
- Symptoms include syncope, exertional dyspnea, pulmonary edema, and paroxysmal nocturnal dyspnea.
- Myxoma fragments can embolize, causing strokes (left-sided) or pulmonary emboli (right-sided).
- Elevated interleukin-6 levels from myxomas may lead to fever, weight loss, and malaise.
