Patient handout

Cardiac tamponade — radiation-induced pericardial disease

PRODUCTION

1. Your condition

This handout is for cardiac tamponade — radiation-induced pericardial disease. Your care team identified this based on: cancer survivor (hodgkin lymphoma, breast, lung, esophageal) with chest radiation history >30 gy or mean heart dose >5 gy presenting with dyspnea, edema, fatigue (esc 2015 §radiation-induced; lyon ehj 2022 pmid 35993161).

Other reasons your team may use this plan: echo with pericardial thickening or new effusion in radiation survivor (esc 2015); acute pericarditis within weeks of completing radiation course (less common with modern conformal techniques) (heidenreich jacc 2010); years-decades post-radiation: insidious dyspnea + edema + ascites + jvd with kussmaul sign → constrictive pericarditis (esc 2015; bertog ehj 2004).

2. Your medications

Take these medications exactly as prescribed. Do not stop or change a dose without talking to your provider.

Medication	Starting dose	How	When	What it does
ibuprofen	600 mg PO TID × 1-2 wk then taper over 2-4 wk	PO	TID	ESC 2015 Class I + ICAP (Imazio NEJM 2013 PMID 23992557) — first-line anti-inflammatory for acute pericarditis
colchicine	0.5 mg BID (0.5 mg daily if <70 kg or eGFR 30-60) × 3 mo	PO	BID	ICAP (Imazio NEJM 2013 PMID 23992557) — RR 0.62 for recurrence; CORP (Imazio Ann Intern Med 2011 PMID 21788540) for recurrent
acetaminophen	650-1000 mg q6h	PO	q6h	Alternative analgesic when NSAIDs contraindicated (renal impairment, anticoagulation)
prednisone	0.2-0.5 mg/kg PO daily × 2-4 wk then taper	PO	daily	ESC 2015 Class IIa second-line for refractory pericarditis; AVOID early in radiation tissue due to wound/healing concern; reserve for refractory cases
furosemide	20-40 mg IV/PO daily; titrate to euvolemia	IV/PO	daily-BID	Volume management for constrictive physiology; bridge to definitive surgery (ESC 2015)
normal saline	500-1000 mL bolus pre-drainage	IV	rapid bolus	Bridge preload (ESC 2015)
norepinephrine	0.05-0.1 µg/kg/min titrate MAP ≥65	IV	continuous	Bridge only — does not address obstruction (Roy JAMA 2007)
rilonacept	320 mg SC loading then 160 mg SC weekly	SC	weekly	RHAPSODY (Klein NEJM 2021 PMID 33999548) — IL-1 blockade for recurrent pericarditis; consider for radiation-related recurrent pericarditis

Plan: Radiation-induced pericardial disease — anti-inflammatory for acute pericarditis, drainage for tamponade, pericardiectomy for refractory constriction (ESC 2015 §Radiation-Induced; Lyon EHJ 2022 PMID 35993161; ICAP PMID 23992557)

3. When to call your provider

Contact your care team if any of the following happen:

Recurrent pericarditis → NSAID + colchicine taper + escalate to rilonacept if failing
Constrictive deterioration → cardiothoracic surgery for pericardiectomy reassessment
New cancer recurrence → multidisciplinary reassessment
Late radiation cardiotoxicity (CAD, valvular disease, cardiomyopathy) → cardiology workup
Tamponade recurrence → re-route to acute pathway

4. When to seek emergency care

Call 911 or go to the nearest emergency room right away if you have:

Progressive constrictive pericarditis with refractory volume overload (Kussmaul sign, ascites, peripheral edema) in radiation survivor — pericardiectomy mandatory but high-risk in radiation tissue (ESC 2015 §Constrictive; Bertog EHJ 2004)
Recurrent pericardial effusion despite NSAID + colchicine in radiation survivor — escalate workup (rule out malignancy + effusive-constrictive) + consider pericardial window (ESC 2015; Lyon EHJ 2022)
Surgical decision-making for pericardiectomy in radiation-damaged tissue — multidisciplinary balance of refractory symptoms vs operative mortality 10-20% (Bertog EHJ 2004)
Cancer recurrence vs radiation toxicity attribution challenge in patient with prior chest radiation presenting with new pericardial effusion — comprehensive workup mandatory (Lyon EHJ 2022)
