Cardiology-2018 : The mystery of a deadly recurrent constrictive pericarditis : TB or not TB - Kenechukwu ezue - Einstein Medical Center Suite 303


Constrictive pericarditis is characterized by scarring and loss of elasticity of the pericardium, and subsequently, this leads to signs and symptoms of right heart failure. Common etiologies include previous cardiac surgery, repeated pericarditis, and radiation therapy. However, less common causes include tuberculosis, neoplasms, and autoimmune disorders. Here we present a rare case of constrictive pericarditis of possible tuberculous etiology and review the diagnosis and management of the condition.


A 68-year-old female with a past medical history of hypertension, immune thrombocytopenia, and early cervical cancer (who had been cured surgically with a hysterectomy) presented with worsening shortness of breath on exertion and leg swelling of four weeks duration. She also had an occasional cough productive of whitish sputum. She has a history of contact with active tuberculosis (her father), and she was diagnosed with latent tuberculosis (TB) infection at an early age but did not complete a course of treatment for latent TB. The patient denied having chest pain, fever, and chills, weight loss, night sweat, or malaise. Her physical exam was remarkable for jugular venous distension, positive Kussmaul sign, hepatomegaly, and bilateral lower extremities edema.

Initial labs were significant for thrombocytopenia with a platelet count of 15 000/cm3, B-type natriuretic protein (BNP) 270, international normalized ratio (INR) 1.3, alkaline phosphatase (ALP) 316, and total bilirubin 2.1 (direct bilirubin 1.1). Other lab values including haemoglobin levels, white blood cell count, renal function, and electrolytes were within normal limits. Her EKG showed low voltage QRS complexes in limb leads and T-wave inversion in anterior leads. HIV antibody screen and hepatitis panel were negative. PPD test was positive (15 mm) and chest X-ray showed bilateral pleural effusion and a calcified pericardium.

A thoracentesis was exudative by Light’s criteria and negative for acid-fast bacilli and malignant cells. However, the drainage of the pleural fluid provided the patient with symptomatic relief. Two-dimensional echocardiogram showed prominent septal bounce suggestive of ventricular interdependence and an ejection fraction of 45-50% without segmental wall motion abnormality. The right ventricle appeared to have normal size but was compressed externally by a loculated structure leading to its moderate systolic dysfunction. Right and left heart catheterization was performed which showed significant diastolic equilibration of diastolic pressures consistent with constrictive pericarditis. No evidence of coronary artery disease was seen.

The cardiothoracic surgery team was consulted given the echocardiogram, and cardiac catheterization findings and a pericardiectomy was performed. Intra-operative observations showed an inflammatory process and fibrinous collections along the diaphragmatic surface of the heart, extending anteriorly onto the right ventricle and over the right atrium; along with extensive calcification of the diaphragmatic surface of the right ventricle and posteroinferior left ventricle. The pericardium was resected along with dissection of the calcified adhesions. Post-operative transthoracic echocardiogram (TEE) confirmed improved right ventricular function. The pericardial biopsy showed fibro connective tissue with dystrophic calcification, mixed acute and chronic inflammation and associated fibrin. However, the bilateral pleural effusions persisted, and a pleural biopsy was performed using videoassisted thoracoscopy, and this showed fibrosing pleuritis with fibrin deposition and granulation tissue, no AFB was seen. The patient was re-admitted due to similar symptoms two months later and developed a massive right pleural effusion, progressively worsening heart failure and eventually died of cardiogenic shock.


In constrictive pericarditis (CP) a thickened, scarred, and often calcified pericardium limits the heart’s compliance and subsequently decreases diastolic filling. This will in turn cause dissociation between intra-thoracic and intra-cardiac pressures, increased inter-ventricular dependence causing a right-to-left septal shift, and increased diastolic filling pressures with pressure equalization in all four cardiac chambers.

CP can be diagnosed via different modalities

Doppler echocardiography, in which pericardial thickening, septal bounce, the diminished collapse of the inferior vena cava (IVC), and reversal of flow in expiration in the hepatic veins are suggestive findings.

Cardiac MRI or cardiac CT is also useful in diagnosing CP as they can show pericardial thickening and calcification. These can particularly be helpful when echocardiographic findings are inconclusive.

Severity and chronicity of symptoms in our patient warranted pericardectomy, which was appropriately done. However, she developed right heart failure again two months after the pericardiectomy which was thought to be secondary to recurrent constrictive pericarditis. Recurrent constrictive pericarditis after pericardiectomy has rarely been reported before and can be due to several reasons including incomplete pericardiectomy, recurrent constriction which is unlikely in our case given the short time frame, or extension of the calcification into the myocardium
