Overview
The survival rate in Hodgkin lymphoma, Non-Hodgkin's lymphoma and breast carcinomas has significantly improved with use of radiation therapy. However, radiation therapy to thoracic and mediastinal cancers have also led to the development of pericarditis, coronary artery disease, cardiomyopathy, conduction abnormalities in heart and valvular heart diseases which account for significant morbidity and mortality. The incidence is higher with doses greater than 40 Gy (4000 rad).
Historical Perspective
Classification
Based on the presentation and onset of symptoms, the radiation-induced pericardial disease may be classified as:[1]
- Acute pericarditis
- Delayed pericarditis
- Pancarditis
- Constrictive pericarditis
- Pericardial effusion
Pathophysiology
Radiation therapy disrupts endothelial cells of the microvasculature of the pericardium and leads to repeated episodes of ischemia. The final result is the formation of fibrosis and fibrinous exudates that are ultimately replaced by fibroblasts and collagen fibers [2][3][4][5].
Radiation-induced pericarditis depends on:
- Total dose of radiation
- Amount of cardiac silhouette exposed
- Nature of the radiation source
- Duration and fractionation of therapy
In a retrospective study, 27.7% of the patients developed pericardial effusion after median time period of 5.3 months following radiotherapy for esophageal carcinoma with radiation dose ranging between 3 to 50Gy. It was concluded that high dose-volume of the irradiated pericardium and heart increased the risk of developing pericarditis[6].
Causes
Radiation-induced pericardial disease can occur in any cancer survivor who receive thoracic radiation therapy, including breast cancer, Hodgkin's lymphoma, esophageal cancer, and lung cancer. However, most data come from patients treated for breast cancer and Hodgkin's lymphoma, in which radiation therapy is a frequent component of management.
Differentiating Radiation-induced Pericarditis from other Diseases
- Pericarditis must be differentiated from diseases presenting with chest pain, shortness of breath and tachypnea.
- For a full discussion of the differential diagnosis of chest pain click here
- For an expert algorithm that aids in the diagnosis of the cause of chest pain click here
- Pericarditis must be differentiated from myocardial infarction as an important cause of chest pain.The differentiating features include:[7]
| Characteristic/Parameter | Pericarditis | Myocardial infarction |
|---|---|---|
| Pain description | Sharp, pleuritic, retro-sternal (under the sternum) or left precordial (left chest) pain. | Crushing, pressure-like, heavy pain. Described as "elephant on the chest". |
| Radiation | Pain radiates to the trapezius ridge (to the lowest portion of the scapula on the back) or no radiation. | Pain radiates to the jaw, or the left or arm, or does not radiate. |
| Exertion | Does not change the pain | Can increase the pain |
| Position | Pain is worse supine or upon inspiration (breathing in) | Not positional |
| Onset/duration | Sudden pain, that lasts for hours or sometimes days before a patient comes to the ER | Sudden or chronically worsening pain that can come and go in paroxysms or it can last for hours before the patient decides to come to the ER |
Epidemiology and Demographics
Pericardial changes are the most common cardiac complications of radiation therapy[3]. Incidence of radiation induced pericarditis has significantly decreased with the use of lower doses and newer radiotherapy techniques [8][9][10]. In a study, incidence decreased from 20% to 2.5% with the changes in methods of RT administration[8]
In as study among pediatric population with various cancers, radiation therapy with ≥15 GY increased the risk of developing pericarditis by two to six times[11]

Diagnosis
Diagnostic Study of Choice
There are no established criteria for radiation induced pericarditis.
History and Symptoms
- Acute pericarditis: Acute pericarditis is a rare complication of radiation therapy. It presents with nonspecific pericarditis symptoms such as chest pain and fever shortly after radiation therapy[1][3].
- Delayed pericarditis: Delayed pericarditis occurs from months to years after exposure to radiation [12][13]. It usually presents with:
- Chest pain
- Dyspnea
- Orthopnea
- Pericardial effusion: Protein-rich exudate may accumulate in the pericardial sac leading to pericardial effusion. Rapid accumulation may result in the development of cardiac tamponade presenting with clinical signs and symptoms of tamponade[3][12].
- Constrictive pericarditis: Constrictive pericarditis is a late complication of radiation therapy. Patients typically present with signs and symptoms of heart failure, similar to other causes of constrictive pericarditis[3].
Physical Examination
Physical examination of patients with radiation-induced pericarditis depends on the presentation. In acute pericarditis, the physical examination may show fever and pericardial rub. In patients presenting with tamponade physical examination may show:
- Hypotension
- Tachycardia
- Jugular venous distention with a prominent Y descent
- Kussmaul's sign, and distant heart sounds
In constrictive pericarditis, signs of congestive heart failure may be present, including:
- Hepatomegaly
- Ascites
- Ankle edema [3]
Laboratory Findings
Laboratory findings consistent with the diagnosis of radiation-induced acute pericarditis include elevated inflammatory markers such as neutrophil count and erythrocyte sedimentation rate (ESR)[3].
Electrocardiogram
In acute pericarditis, non-specific ST and T wave changes or ST segment elevation in all leads may be noted[1][3].
In patients presenting with constrictive pericarditis, electrocardiographic changes are similar to other causes of constrictive pericarditis. Electrocardiographic signs of constrictive chronic pericarditis is usually inconsistent and non specific[14]
- Left atrial enlargement
- Frequent atrial arrhythmias
- Right axis deflection
- Possible reduction in voltages
- Diffuse negative T-waves
- Typical (normal QRS axis, low voltage, and generalized T wave flattening or inversion)
- Right ventricular hypertrophy
- Right axis deviation
X-ray
Echocardiography or Ultrasound
CT scan
MRI
Other Imaging Findings
Other Diagnostic Studies
Pericardiocentesis
- Radiation induced pericardial effusion can be confused with malignant pericarditis and hypothyroidism (secondary to mediastinal irradiation) induced pericarditis.
- Pericardiocentesis can be used to differentiate them with fluid analysis for malignant cells and thyroid function tests.

Treatment
Medical Therapy
Surgery
- Pericarditis with large effusion can be drained either percutaneously or surgically
- Those with recurrent pericardial effusion can be treated with pericardiotomy(pericardial window) or by surgical stripping.
- Pericardiectomy is recommended for patients who develop constrictive pericarditis. However, the perioperative mortality rate is higher in postradiation constrictive pericarditis compared to that of idiopathic constrictive pericarditis[15].
