Quilted Heart Syndrome (Post‑Cardiac Surgery)

Overview

Quilted Heart Syndrome (QHS), also called post‑cardiotomy constrictive pericarditis or “pericardial quilting,” is a rare but potentially serious condition that can develop after open‑heart surgery (e.g., coronary artery bypass grafting, valve replacement, or congenital defect repair). The term “quilted” describes the dense, fibrotic adhesions that form between the visceral and parietal pericardium, giving the heart a “patched‑together” appearance on imaging.

  • Who it affects: Primarily adults undergoing median sternotomy; incidence is higher in patients with repeated cardiac operations or extensive pericardial manipulation.
  • Prevalence: Reported in 0.2‑2 % of post‑cardiotomy patients, with a higher rate (up to 6 %) after multiple surgeries or in those with post‑operative pericardial effusion.
  • Typical onset: Weeks to months after surgery, but cases have been documented up to 2 years later.

QHS results in impaired diastolic filling, reduced cardiac output, and sometimes chronic chest discomfort. Early recognition is key because timely treatment can restore normal hemodynamics and prevent irreversible heart failure.

Symptoms

Symptoms vary from subtle fatigue to overt heart failure. The following list includes the most frequently reported manifestations, along with brief descriptions:

  • Dyspnea on exertion: Shortness of breath when climbing stairs or walking a short distance.
  • Orthopnea: Need to sleep with multiple pillows or sit upright to breathe comfortably.
  • Paroxysmal nocturnal dyspnea (PND): Sudden awakening with severe breathlessness.
  • Fatigue / low exercise tolerance: Persistent tiredness unrelated to activity level.
  • Chest discomfort: Dull, pressure‑like pain that may worsen with deep breathing or lying flat.
  • Peripheral edema: Swelling of the ankles, feet, or lower legs, often worse at day’s end.
  • Abdominal bloating or ascites: Fluid accumulation in the abdomen (rare, usually late stage).
  • Palpitations: Awareness of a rapid or irregular heartbeat.
  • Reduced urine output: Sign of low cardiac output and renal hypoperfusion.
  • Jugular venous distention (JVD): Visible neck vein swelling when sitting upright.

Because many of these signs mimic other post‑operative complications (e.g., pericardial effusion, myocardial infarction), a high index of suspicion is essential.

Causes and Risk Factors

Primary Pathophysiology

After sternotomy, the visceral (inner) and parietal (outer) pericardial layers are exposed and can become inflamed. Healing may lead to excessive fibrosis and the formation of dense, collagen‑rich adhesions (“quilts”) that tether the heart to the surrounding chest wall. This restricts the heart’s normal expansion during diastole, producing a constrictive physiology.

Key Risk Factors

  • Repeated cardiac surgery: Re‑entry into the chest increases pericardial trauma.
  • Prolonged cardiopulmonary bypass (CPB) time: Longer CPB duration correlates with higher inflammatory response.
  • Post‑operative pericardial effusion or hemorrhage: Fluid collections provoke inflammation and fibrosis.
  • Radiation therapy to the chest: Prior mediastinal radiation potentiates scarring.
  • Autoimmune disorders: Conditions such as systemic lupus erythematosus can augment pericardial inflammation.
  • Infection: Post‑operative mediastinitis or bacterial pericarditis accelerates scar formation.
  • Advanced age and female gender: Some series report a modestly higher incidence in women over 60.

Understanding these factors helps clinicians tailor surveillance after surgery.

Diagnosis

Diagnosis is a combination of clinical assessment, imaging, and hemodynamic testing. Because the condition is rare, it is often a diagnosis of exclusion.

Step‑by‑step Diagnostic Approach

  1. History & Physical Examination
    • Identify timing of symptom onset relative to surgery.
    • Look for signs of constriction: Kussmaul’s sign (rise in JVP on inspiration), pericardial knock, pulsus paradoxus.
  2. Electrocardiogram (ECG)
    • May show low voltage, nonspecific ST‑T changes, or atrial arrhythmias.
  3. Chest X‑ray
    • Can reveal a normal cardiac silhouette or mild calcification of the pericardium.
  4. Echocardiography (Transthoracic / Transesophageal)
    • Key findings: abnormal septal bounce, respiratory variation in mitral inflow velocities, dilated inferior vena cava with reduced respiratory collapse.
    • Distinguishes QHS from pericardial effusion (which shows tamponade physiology).
  5. Cardiac Magnetic Resonance Imaging (CMR)
    • Gold standard for visualizing pericardial thickness (≥4 mm) and “quilting” fibrosis.
    • Late gadolinium enhancement helps differentiate active inflammation from chronic scar.
  6. Computed Tomography (CT) Scan
    • Provides high‑resolution images of calcified pericardium and precise measurement of thickness.
  7. Cardiac Catheterization (Hemodynamic Study)
    • Shows equalization of diastolic pressures in all chambers, a “dip‑and‑plateau” (square‑root) waveform, and rapid early diastolic filling.
    • Confirms constrictive physiology when non‑invasive tests are equivocal.
  8. Pericardial Biopsy (Rare)
    • Reserved for atypical cases where infection or malignancy cannot be ruled out.

Guidelines from the American College of Cardiology (ACC) and the European Society of Cardiology (ESC) recommend using a combination of echocardiography and CMR/CT before proceeding to invasive hemodynamic testing.1

Treatment Options

Therapy aims to relieve constriction, restore diastolic filling, and manage symptoms. A multidisciplinary team (cardiologist, cardiothoracic surgeon, physiotherapist, and pain specialist) is ideal.

Medical Management

  • Anti‑inflammatory agents: High‑dose NSAIDs (e.g., ibuprofen 600 mg TID) or colchicine 0.6 mg BID for 3‑6 months can reduce residual inflammation when diagnosed early.2
  • Diuretics: Loop diuretics (furosemide) for volume overload; careful monitoring needed to avoid hypotension.
  • ACE inhibitors/ARBs: Useful in patients with concomitant systolic dysfunction.
  • Beta‑blockers: Control heart rate and reduce palpitations; especially beneficial if atrial fibrillation is present.
  • Anticoagulation: Indicated only if atrial fibrillation or thromboembolic risk is established; not routine for QHS alone.

Surgical Intervention

When fibrosis is extensive, medical therapy is insufficient. The definitive treatment is pericardiectomy (removal of the constricting pericardium).

  • Approaches:
    • Median sternotomy (most common, provides excellent exposure).
    • Left anterolateral thoracotomy (used for isolated lateral constriction).
  • Outcomes: Mortality rates range from 2‑8 % in high‑volume centers, with >80 % of patients experiencing symptomatic improvement.3
  • Risks: Bleeding, infection, residual constriction, and rare ventricular injury.

Percutaneous Options (Emerging)

In selected patients with focal constriction, minimally invasive percutaneous balloon pericardiotomy has been reported, but data remain limited.4

Rehabilitation & Lifestyle Modifications

  • Gradual aerobic conditioning (e.g., walking, stationary cycling) 3‑5 days/week, beginning 4‑6 weeks post‑surgery.
  • Low‑sodium diet (<2 g/day) to control fluid retention.
  • Weight management – aim for BMI < 25 kg/m².
  • Avoid heavy lifting or isometric exercises for at least 12 weeks after pericardiectomy.

Living with Quilted Heart Syndrome (post‑cardiac surgery)

Long‑term management focuses on symptom control, monitoring, and maintaining quality of life.

Daily Management Tips

  1. Medication adherence: Use a weekly pill organizer; set alarms for morning and evening doses.
  2. Fluid monitoring: Limit intake to 1.5‑2 L/day unless instructed otherwise by your cardiologist.
  3. Weight tracking: Weigh yourself each morning; a gain of ≥2 lb in 24 hours may signal fluid accumulation.
  4. Activity pacing: Follow the “4‑minute rule”: walk until slightly out of breath, then rest for 4 minutes before resuming.
  5. Vaccinations: Annual influenza vaccine and COVID‑19 booster reduce risk of respiratory infections that can worsen heart failure.
  6. Follow‑up schedule: Cardiology visits every 3‑6 months for the first year, then annually if stable.
  7. Support network: Consider joining a heart‑failure support group; psychosocial health improves outcomes.

When to Contact Your Provider

  • New or worsening shortness of breath.
  • Sudden weight gain (>5 lb in 3 days).
  • Increasing leg swelling or abdominal bloating.
  • Fainting, dizziness, or palpitations.
  • Persistent chest discomfort that does not improve with rest.

Prevention

Because QHS arises after cardiac surgery, preventive strategies focus on minimizing pericardial injury and inflammation.

  • Meticulous surgical technique: Use of protective pericardial barriers and minimizing pericardial stripping.
  • Limited cardiopulmonary bypass time: Employ off‑pump techniques when feasible.
  • Prophylactic anti‑inflammatory regimen: Colchicine 0.6 mg daily for 3 months after surgery has shown a reduction in post‑pericardiotomy syndrome (PPS) incidence.5
  • Prompt treatment of post‑operative pericardial effusion: Drainage when effusion exceeds 20 mm on echocardiography.
  • Control of modifiable risk factors: Tight glycemic control in diabetics, smoking cessation, and management of hypertension.

Complications

If QHS remains untreated or is recognized late, several serious complications can develop:

  • Chronic heart failure: Persistent diastolic dysfunction leading to reduced exercise capacity.
  • Cardiac cachexia: Unintentional weight loss due to catabolic state.
  • Arrhythmias: Atrial fibrillation or flutter secondary to atrial stretch.
  • Thromboembolic events: Stasis in dilated atria increases stroke risk.
  • Hepatorenal syndrome: Severe right‑sided congestion causing liver and kidney dysfunction.
  • Mortality: Reported 5‑year mortality up to 15 % in patients who never undergo pericardiectomy.6

When to Seek Emergency Care

Call 911 or go to the nearest emergency department immediately if you experience any of the following:
  • Sudden severe shortness of breath or inability to speak full sentences.
  • Chest pain that is crushing, radiates to the left arm or jaw, or is accompanied by sweating.
  • Rapid heart rate (>130 bpm) with dizziness, fainting, or near‑syncope.
  • Sudden swelling of the abdomen with a feeling of fullness.
  • New onset of severe palpitations with feeling of “fluttering” or “racing.”
  • Rapid weight gain (>5 lb in 24 hours) with swelling of the legs and shortness of breath.
