obsolete metastasis to heart

Metastatic Calcification in the Pulmonary Tissue

The metastatic calcification in the pulmonary tissue is a known complication to chronic renal failure and other disturbances to calcium metabolism, and can also be caused by cardiac metastases [9]. This condition occurs when there is an abnormal deposition of calcium salts in the lungs, leading to fibrosis and scarring.

Cardiac Metastasis

Metastatic disease to the heart and pericardium is a relatively rare occurrence, but it can have significant consequences. According to some studies, up to 12% of oncology patients have metastases to the heart or pericardium at autopsy [14]. The most common symptoms attributable to cardiac metastasis are nonspecific and mimic other cardiac diseases such as myocardial ischemia, heart failure, or cardiac injury related to chemotherapy or radiation therapy [13].

Types of Cardiac Metastases

Cardiac metastases can occur in various forms, including:

• Pericardial effusion: A fluid accumulation in the pericardial space, which can be serosanguineous or hemorrhagic.
• Myocardial invasion: Direct invasion of the myocardium by tumor cells.
• Great vessel involvement: Metastasis to the great vessels, such as the aorta or pulmonary arteries.

Incidence and Prevalence

The exact incidence of cardiac metastatic disease is difficult to determine, but it is estimated that between 0.7% and 3.5% of patients at autopsy have secondary metastatic tumors to the pericardium, myocardium, great vessels, or coronary arteries [10]. In patients with known malignancies, this percentage can be as high as 9.1% [10].

[13] Most patients with metastatic disease to the heart and pericardium are asymptomatic [].When present, symptoms depend on the size and location of the metastasis ().The most common symptoms attributable to cardiac metastasis are nonspecific and mimic other cardiac diseases such as myocardial ischemia, heart failure, or cardiac injury related to chemotherapy or radiation therapy.

[14] Up to 12% of oncology patients have metastases to the heart or pericardium at autopsy, although most remain clinically silent . Melanomas have the greatest propensity for cardiac involvement ( 116 ), whereas carcinomas of the thorax, including breast, lung, and esophageal, are the most common carcinomas that metastasize to the heart.

Obsolete metastasis to the heart, also known as cardiac metastases, can be a challenging diagnosis due to their rarity and non-specific symptoms. However, here are some possible signs and symptoms that may indicate metastatic disease to the heart:

1. Dyspnea (shortness of breath): This is often one of the first symptoms reported by patients with cardiac metastases.
2. Chest pain: Pain or discomfort in the chest can occur due to tumor infiltration into the myocardium (heart muscle) or pericardial involvement.
3. Palpitations: Irregular heartbeats, rapid heartbeat, or skipped beats may be experienced by patients with cardiac metastases.
4. Fatigue: Feeling tired or weak, even after minimal exertion, can be a symptom of cardiac metastases.
5. Edema (swelling): Swelling in the legs, ankles, or feet due to fluid accumulation can occur as a result of tumor-induced heart failure.
6. Coughing up blood (hemoptysis): In rare cases, patients with cardiac metastases may experience coughing up blood due to tumor involvement in the lungs or airways.
7. Syncope (fainting): Sudden loss of consciousness can occur if the tumor causes a significant obstruction in the heart's ability to pump blood effectively.
8. Orthopnea: Shortness of breath when lying down, which improves with sitting

Diagnostic Tests for Metastatic Disease to the Heart

Metastatic disease to the heart, also known as cardiac metastases, can be challenging to diagnose. However, various diagnostic tests can help identify this condition.

• Imaging studies: Imaging tests are essential in diagnosing and monitoring cardiac metastases. These may include:
  • Chest x-ray: May demonstrate cardiomegaly (enlargement of the heart) due to metastatic disease [4].
  • Echocardiography: A non-invasive test that uses sound waves to create images of the heart. It is often used as an initial diagnostic test to evaluate for cardiac metastatic disease [7, 14].
  • Cardiac MRI (CMR): Considered the reference standard for early assessment and differentiation between nonneoplastic and tumor masses [9]. CMR can help identify metastatic lesions in the heart.
  • CT scans: May be used to evaluate the extent of metastatic disease in the chest and other areas.
• Cytologic evaluation: Cytologic evaluation of pericardial effusion specimens after pericardiocentesis is frequently used to diagnose a metastatic malignancy involving the heart [3].
• Multimodality imaging approach: A combination of echocardiography, MRI, and CT scans may be favorable for early detection of cardiac metastasis in patients presenting with symptoms [5].

It's essential to note that the choice of diagnostic test depends on the individual patient's condition and medical history. A radiologist's ability to evaluate cardiac metastases hinges on an understanding of the epidemiology, anatomy, and imaging features of this disease process [8].

Treatment Options for Metastasis to the Heart

Metastasis to the heart, also known as cardiac metastasis, occurs when cancer cells from another part of the body spread to the heart. While there are no specific treatments that target metastasis to the heart directly, various therapies can help manage symptoms and improve quality of life.

• Chemotherapy: This is a systemic treatment that uses medications to kill cancer cells throughout the body, including those in the heart. Chemotherapy may be used to treat metastatic heart tumors, especially if they are part of a larger cancer diagnosis.
• Surgery: Surgical removal of the tumor or affected area can be an option for some patients. However, this approach is typically reserved for cases where the tumor is localized and not widespread throughout the heart.
• Targeted therapies: These medications specifically target certain types of cancer cells, such as those with specific genetic mutations. Targeted therapies may be used to treat metastatic heart tumors if they are part of a larger cancer diagnosis.

Other Treatment Options

In addition to these treatments, other options may be considered to manage symptoms and improve quality of life:

• Pain management: Medications can help alleviate pain caused by the tumor or its effects on the heart.
• Fluid management: In some cases, fluid buildup in the chest (pericardial effusion) may require drainage to relieve pressure on the heart.
• Cardiac medications: Certain medications can help manage symptoms related to cardiac metastasis, such as shortness of breath or arrhythmias.

Current Research and Future Directions

Research is ongoing to better understand the biology of cardiac metastasis and develop more effective treatments. Some studies are exploring the use of novel therapies, such as immunotherapies, to target cancer cells in the heart.

• Immunotherapy: This approach uses the body's immune system to fight cancer. Researchers are investigating whether immunotherapies can be used to treat metastatic heart tumors.
• Targeted therapies: Scientists are working on developing targeted therapies that specifically target cancer cells in the heart, reducing harm to healthy tissues.

Differential Diagnosis of Cardiac Metastases

Cardiac metastases are rare, but their differential diagnosis can be complex and varied. The following conditions should be considered in the differential diagnosis of cardiac metastases:

• Atrial myxoma: A type of benign tumor that can occur in the heart (Carrick, 2024 [2]; Carrick, 2024 [4])
• Thrombus in transit: A blood clot that has broken loose from its original site and is traveling through the bloodstream (Carrick, 2024 [3]; Ashraf, 2022 [6])
• Metastatic HCC: Liver cancer cells that have spread to the heart (Carrick, 2024 [2]; Carrick, 2024 [4])
• Cardiac metastasis from CRC: Cancer cells from the colon or rectum that have spread to the heart (Tsujii, 2017 [8])
• Structural valvular pathologies: Conditions such as stenosis or insufficiency of the heart valves (Gad, 2020 [9])
• Infective endocarditis: A bacterial infection of the heart valves (Gad, 2020 [9])

Symptoms and Signs

The symptoms and signs of cardiac metastases can be nonspecific and mimic other cardiac diseases. They may include:

• Rapid increase in heart size by pericardial effusion
• New signs of heart failure or valve disease
• Conduction defects
• Atrial or ventricular heart rhythm disturbances (Tsujii, 2017 [8]; Ashraf, 2022 [6])
• Dyspnea or tachypnea
• Systolic heart murmur
• Peripheral edema

Prognosis and Treatment

The prognosis for cardiac metastases is generally poor, with a median survival time of 3-6 months (Ashraf, 2022 [6]). Treatment options may include surgery, chemotherapy, or radiation therapy.
