Constrictive pericarditis in patients with tuberculous pericarditis.

Constrictive pericarditis is a complication of tuberculous pericarditis that necessitates surgical intervention. In this study, we sought to identify echocardiographic features that could predict the development of constrictive pericarditis from acute or subacute pericarditis. From January 1988 through May 1998, all patients with a discharge diagnosis of tuberculous pericarditis were enrolled in the study, and their clinical features, laboratory findings, sonographic images, treatments, and outcomes were analyzed. Tuberculous pericarditis was demonstrated on the basis of positive Mycobacterium tuberculosis cultures from pericardial fluid or tissue in 11 patients; pericardial biopsy specimens demonstrating caseating granulomas in seven; and bacteriologic or histologic evidence of active extra-pericardial tuberculosis in conjunction with major pericardial effusion in four. Seventeen patients had effusive tuberculous pericarditis and five had constrictive tuberculous pericarditis as the initial diagnosis. The echocardiographic findings of effusive pericarditis were classified as shaggy-type effusion (n = 8) and non-shaggy-type effusion (9). Shaggy effusion was defined as the presence of multiple fibrin strands or a mass-like exudate coating the pericardium and bridging the pericardial effusion. Non-shaggy effusion was characterized by an anechoic pericardial space with or without a thickened pericardium, but no shaggy exudative coating. The mean duration between the onset of symptoms and diagnosis was longer in patients with shaggy-type effusion (39.6 +/- 8.7 vs 21.0 +/- 13.9 days, p < 0.05). Prednisolone (20-30 mg/d) was used in addition to antituberculous chemotherapy in 11 of the 17 patients with effusive pericarditis. Two of 11 patients (18%) who received steroid therapy, and five of the six patients (83%) who did not, developed constrictive pericarditis in the following year. Therefore, we concluded that adjuvant therapy with steroids significantly decreased the risk of constrictive pericarditis in patients with non-shaggy, but not shaggy, effusion.

Radionuclide angiography and magnetic resonance imaging: complementary non-invasive methods in the diagnosis of constrictive pericarditis.

Constrictive pericarditis presents with a suggestive clinical picture, and its diagnosis is based on a haemodynamic pattern revealing impaired ventricular filling. In this study of 15 patients with pure isolated constrictive pericarditis, we attempted to evaluate the diagnostic value of two non-invasive methods not usually employed in this indication: radionuclide angiography (RNA) and magnetic resonance imaging (MRI). Whilst RNA permits analysis of the functional pattern of the global and segmental left ventricular filling impairment, MRI allows measurement of the thickness of the pericardium. RNA revealed increased early diastolic filling as evidenced by a shorter one-third filling time (TF1/3; P<0.0001 with respect to a normal population), a higher peak filling rate (PFR; P<0.01) and its early occurrence (P<0.001), increased one-third and mid diastolic filling fractions (P<0.01), and the ratio of the PFR over the peak ejection rate (P<0.01). During late diastole, the atrial filling fraction decreased (NS). The patients with constrictive pericarditis also showed a decrease in the physiological filling asynchrony, as assessed by segmental evaluations. Seven patients underwent MRI. The pericardium was thickened in all the patients, varying from 6 to 14 mm (normal: 2.5+/-0.7 mm), without any systolo-diastolic variation. Pericardial thickening appeared as a dark low-intensity signal band, demonstrating the fibrocalcific nature of the pericardial contents. Sagittal and coronal cross-sections were particularly well-suited to show the non-uniformity of the pericardial thickening. These results indicate that RNA and MRI are complementary non-invasive methods, and can provide the functional and anatomical information required for the diagnosis of constrictive pericarditis.

[A case of tuberculous pericarditis developing constrictive pericarditis].

A case of constrictive pericarditis which developed after the onset of clinical manifestation of tuberculous pericarditis was reported. A 75-year-old male, complaining of anorexia, was admitted to our hospital. Adenosinedeaminase (ADA) level in pericardial effusion was found to be increased, and the culture of pericardial effusion was positive for tubercle bacilli. Diagnosed as having tuberculous pleuritis and pericarditis, he underwent chemotherapy for tuberculosis. However, massive pleural effusion developed later and pleural effusion drainage was carried out. Despite repeated drainage, pleural effusion continued to recur. Chest CT revealed apparent pericardial thickening, in addition, cardiac catheterization revealed elevation of mean right atrial pressure and marked deterioration of cardiac functions including decrease of cardiac output. These findings were compatible with constrictive pericarditis. After these investigations a diagnosis of constrictive pericarditis was established, and the patient underwent a pericardiectomy. Pathological examination of resected specimens revealed tuberculous inflammation.

Indications, results, and pitfalls in the surgery of constrictive pericarditis.

Constrictive pericarditis is a rare disease with an often unclear etiology. There may be a long delay between the onset of the underlying disease and the onset of clinical symptoms, which are fatigue, abdominal swelling, peripheral edema and breathlessness. However, if clinically apparent, these symptoms may progress rapidly and severely disable the affected patient. Diagnosis is achieved by the clinical presentation, echocardiography and/or MRI and right heart catheterization. The standard therapy is an extended pericardiectomy to restore an unlimited inflow and outflow as well as an unrestricted diastolic function of both ventricles. The risks of this procedure are related to dense adhesions between the 2 pericardial layers and severe calcifications especially of the epicardium. Incomplete removal results in persistent diastolic restriction while lacerations of the underlying myocardium may lead to diffuse and extensive bleeding and finally to myocardial dysfunction. Also, the postoperative course may be complicated by persistent low output syndrome or acute ventricular dilatation. However, early surgical intervention in the hands of experienced surgeons offers the best prognosis.

CT and MRI findings in a child with constrictive pericarditis.

Constrictive pericarditis is rare in children. We report computed tomography (CT) and magnetic resonance imaging (MRI) findings in a 3-year-old girl. She had a swollen abdomen that increased in two months. CT and MRI showed a thickened pericardium (5.2 mm) without calcification. Both atria were enlarged and ventricles were relatively small. The engorged inferior vena cava had 2.8x the diameter of the descending aorta at the same level. Symptoms were dramatically improved after pericardiectomy. The histopathological features confirmed chronic pericarditis.

Role of echocardiography in detecting the anatomic and physiologic abnormalities of constrictive pericarditis.

Constrictive pericarditis (CP) is associated with thickening of the pericardium (P), rapid filling of the ventricles, and a steep rise of early diastolic pressure in the right and left ventricles. We investigated the frequency with which echocardiography detects the characteristic anatomic and physiologic abnormalities of CP. M-mode echocardiography was performed in 10 patients with CP. All patients had evidence of pericardial thickening. Eight patients had motion of the P parallel to the epicardium with an echo-free space between the two structures. Two patients had a small pericardial and left pleural effusion sandwiching the P which measured 8 mm, and 14 mm respectively. Premature pulmonic valve opening indicating a high right ventricular early diastolic pressure which exceeded the pulmonary artery diastolic pressure was present in all 5 patients in whom the pulmonic valve was recordable. A notch on the septum in early diastole was seen in 6 patients. Sharp posterior motion of the left ventricular posterior wall in early diastole followed by a flat segment was noted in 7 patients. Motion of the posterior wall of the aortic root (PWAo) in diastole has been shown to indicate left atrial volume changes or reflect left ventricular filling. An index of early diastolic left ventricular filling derived from the motion of the posterior wall of the aortic root, indicated abnormally rapid early diastolic filling in all 8 patients in whom this was measured. We conclude: 1) The anatomic and physiologic abnormalities in CP are commonly reflected on the echocardiogram, and 2) echocardiography should be useful in evaluation of patients suspected of having CP.

[Extracardial manifestations in constrictive pericarditis].

Constrictive pericarditis is a slowly progressive disabling disease. The diagnosis is easily overlooked because of the striking extracardial signs and symptoms such as abdominal discomfort, general fatigue, cachexia, ascites and oedema. We describe 7 patients with these symptoms in whom the diagnosis was missed during 0.5-17 years. The decisive clue for correct diagnosis appeared to be the raised central venous pressure. This proves the importance of an accurate physical examination. Other findings were: ascites (7/7), hepatomegaly (7/7), oedema (6/7), narrow pulse pressure (less than or equal to 35 mmHg) (5/7), ECG abnormalities (7/7) and pericardial calcifications on the chest X-ray (5/7). In addition we found slightly raised liver enzymes and a protein-losing enteropathy leading to low serum protein levels. These abnormalities are all explained by the alterations in haemodynamics and lymph flow. The only curative therapy is surgical decortication of the heart.

Constrictive pericarditis.

Constrictive pericarditis is a complex disorder characterized by abnormal thickening of the pericardium that leads to pathologic changes in cardiac hemodynamic data. The disorder can be suspected by history and physical findings. Data from echocardiography, CT, and MRI offer diagnostic information. The diagnosis cannot generally be established with certainty by noninvasive methods. Additional information from cardiac catheterization may help confirm the diagnosis. Together, these diagnostic modalities aid in the assessment of disease and help to differentiate it from related conditions such as restriction, cardiac tamponade, and right ventricular infarction. Treatment is largely surgical, and new techniques and approaches have made it relatively safe. Early diagnosis and pericardiectomy may lead to cure in most patients.

CT in tuberculous constrictive pericarditis.

Constrictive pericarditis (CP) and restrictive cardiomyopathy have the same pathophysiological disorder (impaired diastolic filling) and a similar presentation. To determine the value of a noninvasive technique, CT, in differentiating between the two, we reviewed the CT scans of 212 patients with clinical signs and symptoms of CP and/or restrictive cardiomyopathy, after 26 cases that did not proceed to surgery were excluded. Computed tomography showed pericardial thickening (greater than 3 mm) in 157 patients with proven tuberculous CP. In two children with proven constriction, the pericardium measured between 2 and 3 mm. We determined that pericardial thickening, in the correct clinical setting, is the only CT sign necessary to diagnose CP. Other CT signs, inferior vena cava dilatation (97%), and deviation of the interventricular septum (15%) were confirmatory. Computed tomography accurately differentiates between CP and restrictive myocardial disease, making more invasive modalities such as cardiac catheterization and endomyocardial biopsy, with few exceptions, unnecessary.

Constrictive pericarditis.

Constrictive pericarditis, although still a relatively rare disease, continues to be a clinical problem that most practicing cardiologists may encounter. A major clinical clue to diagnosis is the continued elevation of the central venous pressure after adequate diuresis. The diagnosis is further supported by (1) prominent X and Y descents in the jugular venous pulse, (2) a relatively normal or only slightly enlarged cardiac silhouette in a patient with congestive heart failure, (3) pericardial calcification or significant congestive failure especially when the right sided signs predominate without obvious cause. When the disease is suspected, appropriate investigation should be undertaken using both the noninvasive and the catheterization studies. If the diagnosis is supported, then the choice of therapy at present is based primarily on severity of symptoms with surgical removal of the constricting pericardium being the therapy of choice in patients unable to be managed medically.

Constrictive Pericarditis.

Constrictive pericarditis is an uncommon but treatable cause of heart failure that results from a variety of acute inflammatory processes. Corticosteroids appear to prevent the development of constriction in selected patients with active pericardial inflammation. Symptoms of right-sided heart failure usually predominate and can be adequately managed with diuretics. Complete surgical pericardiectomy remains the only definitive treatment. The mortality risk is markedly increased in patients with advanced symptoms, and surgery should be performed in earlier stages. The majority of patients (95% on average) will survive the surgery; complete relief of symptoms occurs in about 50% of survivors. Ten percent of patients will have persistent symptomatic heart failure (New York Heart Association functional class III or IV) and experience poor late outcomes, however, particularly when residual myocardial dysfunction coexists.

[The role of Doppler echocardiography in chronic constrictive pericarditis].

Constrictive péricarditis (CCP) is a rare but serious disease. It still poses diagnostic difficulties. The purpose of our work is to study the contribution of the echocardiographic Doppler in the diagnosis of the CCP. The authors report six cases of CCP proven after surgery. Study by ultrasound Doppler of intracardiac blood flow and their respiratory variations showed the existence of abnormalities. The decrease of 25% of the mitral E wave in inspiration compared to the value observed in expiration, the increase of 100% of the ebb in sus hépatic vein in expiration and the modifications of the flux in pulmonary insufficiency are the most reliable signs for the diagnosis of the CCP. This method seems so interesting for the diagnosis and to estimate the degree of constriction of the CCP.
