[Constrictive pericarditis].

Etiology of constrictive pericarditis is diversified. In recent years the role of viral and iatrogenic factors (X-ray therapy, cardiac surgery) has increased. Clinical manifestations, including subjective complaints, resemble those in congestive heart failure although the mechanism of hemodynamic disorders is different--namely impairment of ventricular filling and diastolic performance. One encounters major difficulties while differentiating constrictive pericarditis from restrictive cardiomyopathy. In some patients conservative treatment is effective, in a majority of them surgical operation, pericardiectomy is the treatment of choice.

[Acute effusive-constrictive pericarditis in influenza A].

Constrictive pericarditis may complicate the course of several viral infections, mainly Coxsackie virus group B, as well as in rheumatoid disease, radiation and neoplasm. Perimyocardial involvement during influenzal infections is usually mild and does not progress to constriction or tamponade. A single case of cardiac tamponade caused by influenza A was reported in 1986. We report a case of acute effusive-constrictive pericarditis due to influenza A infection. Corticosteroids resulted in some benefit, but did not relieve constriction, which required extensive pericardiectomy.

Effusive-constrictive pericarditis.

BACKGROUND: Effusive-constrictive pericarditis is an uncommon pericardial syndrome characterized by concomitant tamponade, caused by tense pericardial effusion, and constriction, caused by the visceral pericardium. We conducted a prospective study of its clinical evolution and management. METHODS: From 1986 through 2001, all patients with effusive-constrictive pericarditis were prospectively evaluated. Combined pericardiocentesis and cardiac catheterization were performed in all patients, and pericardiectomy was performed in those with persistent constriction. Follow-up ranged from 1 month to 15 years (median, 7 years). RESULTS: A total of 1184 patients with pericarditis were evaluated, 218 of whom had tamponade. Of these 218, 190 underwent combined pericardiocentesis and catheterization. Fifteen of these patients had effusive-constrictive pericarditis and were included in the study. All patients presented with clinical tamponade; however, concomitant constriction was recognized in only seven patients. At catheterization, all patients had elevated intrapericardial pressure (median, 12 mm Hg; interquartile range, 7 to 18) and elevated right atrial and end-diastolic right and left ventricular pressures. After pericardiocentesis, the intrapericardial pressure decreased (median value, -5 mm Hg; interquartile range, -5 to 0), whereas right atrial and end-diastolic right and left ventricular pressures, although slightly reduced, remained elevated, with a dip-plateau morphology. The causes were diverse, and death was mainly related to the underlying disease. Pericardiectomy was required in seven patients, all of whom had involvement of the visceral pericardium. Three patients had spontaneous resolution. CONCLUSIONS: Effusive-constrictive pericarditis is an uncommon pericardial syndrome that may be missed in some patients who present with tamponade. Although evolution to persistent constriction is frequent, idiopathic cases may resolve spontaneously. In our opinion, extensive epicardiectomy is the procedure of choice in patients requiring surgery.

Clinical characteristics and treatment of constrictive pericarditis in Taiwan.

BACKGROUND: Constrictive pericarditis is an uncommon disease that prevents the normal diastolic filling of the heart and pericardiectomy is the only satisfactory treatment. METHODS AND RESULTS: The clinical characteristics and treatment of patients who underwent pericardiectomy for constrictive pericarditis (n = 23) were reviewed. Surgery was performed via left anterolateral thoracotomy plus transsternal extension in 3 patients, and median sternotomy in 20 patients. There were 2 deaths, resulting in an overall mortality rate of 8.7%. Of the 23 patients, 8 had Mycobacterium tuberculosis (Tb) infection, 2 had streptococcus infection, 1 had strongyloidiasis (Strongyloides stercoralis) and 1 developed the condition after a myocardial infarction; 2 patients underwent pericardial substitute insertion as post-heart surgery, and 3 patients had connective tissue disorders; 6 patients had idiopathic disease. CONCLUSION: These results show that bacterial infection, especially Tb, is a major etiology of constrictive pericarditis in Taiwan and that median sternotomy is an excellent approach for exposing the heart for pericardiectomy.

Does rapid volume loading during transesophageal echocardiography differentiate constrictive pericarditis from restrictive cardiomyopathy?

BACKGROUND: Respiratory variation of the pulmonary venous (PV) peak flow velocities can be used to distinguish constrictive pericarditis (constriction) from restrictive cardiomyopathy (restriction). Rapid volume expansion has been used successfully to enhance diastolic pressure equalization in occult constriction. The effect of volume on the respiratory variation in constriction has not been studied previously. This study assessed the utility of volume in enhancing the PV respiratory variation of constriction to further separate it from restriction. METHODS: The study population consisted of 15 patients referred to the echocardiography laboratory for further evaluation of clinically suspected diastolic dysfunction. Pulsed-Doppler transesophageal echocardiography (TEE) of the left or right upper pulmonary vein and mitral inflow was performed with respiratory monitoring before and after infusion of 1 liter of normal saline over 5 to 10 minutes. The classification of patients as constriction (n = 8) or restriction (n = 7) was confirmed independently by cardiac catheterization or surgery. Peak velocities of the PV systolic and diastolic waves and the mitral inflow E were measured during inspiration and expiration. A mean of 3-6 respiratory cycles was obtained for each value before and after volume loading. The percent change from expiration to inspiration (%E) was calculated using the formula %E = expiration - inspiration / expiration. RESULTS: At baseline, patients with constrictive pericarditis can be separated reliably from those with restrictive cardiomyopathy based on a higher systolic/diastolic ratio and greater respiratory variation of their PV diastolic flow velocity. There were no complications in any patient due to volume expansion. Although the change from baseline to volume expansion was not statistically significant in either constriction or restriction, the %E of the PV diastolic wave became significantly higher in constriction than in restriction (P < 0.05). CONCLUSIONS: Rapid volume expansion is relatively safe during TEE and can be used for further separation of constrictive pericarditis from restrictive cardiomyopathy by significantly enhancing the respiratory variation of the PV diastolic flow velocity in constrictive pericarditis.

Differentiating constrictive pericarditis from restrictive cardiomyopathy.

Constrictive pericarditis and restrictive cardiomyopathy are 2 forms of diastolic dysfunction with similar presentation but different treatment options. Whereas constrictive pericarditis has the potential of being cured with pericardiectomy, restrictive cardiomyopathy is usually incurable. It is therefore crucial to differentiate between the 2 disorders. In the last few years, new diagnostic techniques have become available to differentiate these causes of diastolic dysfunction from each other. This review provides a complete, in-depth comparison of the 2 disorders with regard to their symptoms and clinical features, etiology, pathophysiology, hemodynamics, echocardiographic presentation, and finally the different available management options.

Observations of angina and myocardial infarction in constrictive pericarditis.

The common symptoms of constrictive pericarditis, i.e. dyspnea on exertion, shortness of breath and cough, relate to impairment of ventricular filling and to a progressive rise in systemic and pulmonary venous pressures. Myocardial ischemia, angina and myocardial infarction are rarely associated with this disease. We have encountered two patients with constrictive pericarditis, one presenting with angina and the other with acute anterior wall infarction. Possible etiologies of constrictive pericarditis in the first case include cardiac surgery, chronic renal failure and myocarditis; in the second case, Crohn's disease. The proposed mechanism of chest pain in the first patient was a reduced cardiac output resulting in underperfusion of the coronary arteries, although it is possible that the patient experienced angina due to the presence of severe coronary artery disease. In the second patient an anterior wall infarction and post-infarction angina were attributed to obliteration of the left anterior descending artery by constraint of a thickened pericardium. In both cases non-invasive imaging modalities were not of use in establishing the diagnosis of constrictive pericarditis. Clinical awareness and accurate hemodynamic measurements continue to play a key role in the diagnostic process.

Constrictive pericarditis complicating dermatomyositis.

Chronic constrictive pericarditis may complicate both rheumatoid arthritis and systemic lupus erythematosus. To our knowledge, however, this is the first time it has been described in a patient with dermatomyositis. This association should be kept in mind as constrictive pericarditis should be considered in the differential diagnosis of liver cirrhosis and Budd-Chiari syndrome in rheumatic diseases.

Protein losing gastroenteropathy in constrictive pericarditis.

A case of constrictive pericarditis with PLGE is reported. It is the nineteenth case in the world literature. The fatal outcome is contributed to late diagnosis and refusal of surgery. It is possible that nine out of sixty eight cases of constrictive pericarditis have suffered from the same condition in a five year period in the same hospital. Early diagnosis is rewarding and could be achieved by a high index of suspicion and an outlook for the diagnostic markers.

Collagen diseases as a cause of constrictive pericarditis.

Seven patients with constrictive pericarditis associated with collagen disease underwent pericardiectomy with good results in all but one. The collagen disease was confirmed as rheumatoid arthritis in five patients, but in two its nature remained obscure. In one case the illness was marked by a persistent eosinophilia and eosinophilic infiltration of the pericardium. The association of constrictive pericarditis with rheumatoid arthritis and other collagenoses is briefly discussed.

[A case of rapidly developed constrictive pericarditis following acute non-specific pericarditis].

A case of constrictive pericarditis which developed within one month after the onset of acute pericarditis was presented. A 3-year-old boy was admitted to our hospital suffering from dyspnea. Pericardectomy was performed 3 weeks after the pericardial drainage. His echocardiograms revealed the progressive thickening of the pericardium, severely restricted ventricular motion in both systole and diastole and paradoxical motion of the interventricular septum. Echocardiography at close intervals is useful for making the diagnosis and decision of the surgical intervention of rapidly developed constrictive pericarditis.

An echocardiographic study of the interventricular septum in constrictive pericarditis.

Ten patients with constrictive pericarditis were studied echocardiographically with specific reference to inter-ventricular septal dynamics. Abnormal movement of the interventricular septum was present in 8 patients and consisted of flattening in systole and unusual posterior motion in diastole. The aetiology of this type of movement is at present unknown but may be related to restriction of normal cardiac rotational dynamics. The interventricular septum also showed diminished degree of thickening (mean 21-2%). The amplitude of excursion was generally at the upper limit of or greater than normal. Left ventricular posterior wall amplitude of excursion was normal. Flattening of left ventricular posterior wall diastolic movement was seen in 4 patients. Right ventricular end-diastolic dimension was slightly increased (1-2 to 1-7 cm/m2) in 5 of 8 patients with abnormal septal motion, but no haemodynamic evidence of diastolic volume overload was found. Posterior pericardial thickening was noted echocardiographically when posterior calcification was present. We conclude that the most common though non-specific feature of the echocardiogram in patients with constrictive pericarditis is abnormal septal motion. Flattening of left ventricular posterior wall diastolic movement, posterior pericardial thickening, and epicardial-pericardial separation may also occur.

[Constrictive pericarditis after cardiac surgery].

Constrictive pericarditis is a rare complication of cardiac surgery. Among 7851 patients who underwent cardiac surgery at Nantes University Hospital, postoperative constrictive pericarditis was diagnosed in 5 patients: 0.63%. All patients were men aged 49 to 77 years (mean 62.5) Four patients underwent coronary artery bypass graft surgery and one patient required mitral and aortic valve replacement. The mean time to onset of symptoms after the first operation was 21 months. The main clinical symptom was right ventricular failure. In all patients, the diagnosis was established by right catheterization which showed diastolic dip-plateau. A radical pericardectomy was performed in all but one of the patients, who was treated medically. Clinical signs resolved in all five patients. The diagnosis of constriction after cardiac-surgery is not easy, as the symptoms are non-specific. A symptomatic patient believed to have myocardial failure after cardiac-surgery could therefore actually instead have occult constriction.

Rate-dependent hemodynamic responses during incremental atrial pacing in chronic constrictive pericarditis before and after surgery.

Chronic constrictive pericarditis is a frequent cause of diastolic dysfunction, and results in impaired ventricular filling. Unlike in normal subjects, ventricular filling in constrictive pericarditis occurs almost entirely in the initial one third of diastole, and cardiac output is dependent predominantly on heart rate. Tachycardia impairs ventricular filling in normal subjects, but its effects in patients with constrictive pericarditis have not been studied. The effect of increasing heart rate alone with atrial pacing on the central and peripheral hemodynamics of patients with untreated chronic constrictive pericarditis before and after pericardiectomy was evaluated. Increased heart rate with atrial pacing increased cardiac output, whereas stroke volume remained unchanged up to heart rates of 140 beats/min. Further increases in heart rate resulted in reductions of cardiac output and stroke volume. There were no significant changes in ventricular filling pressures. Infusion of 300 ml of saline solution at peak pacing rates did not improve cardiac output. After successful surgical pericardiectomy, the hemodynamic effects of atrial pacing returned to normal. It is concluded that moderate tachycardia improves the hemodynamic profile of patients with constrictive pericarditis.

Chylous ascites due to constrictive pericarditis.

Chylous ascites due to constrictive pericarditis is an extremely rare clinical entity, possibly caused by the augmented lymph production and high impedance to lymph drainage due to central venous hypertension. The authors describe a patient with chylous ascites caused by constrictive pericarditis in the absence of lymphatic obstruction. Cardiac catheterization is essential for the confirmation of accurate diagnosis of constrictive pericarditis. Magnetic resonance imaging of the heart is also very helpful in the diagnosis. The patient was symptom free and his ascites and edema completely resolved after pericardiectomy.

Results of subtotal pericardiectomy for constrictive pericarditis.

The operative approach to constrictive pericarditis still remains a surgical challenge. Subtotal pericardiectomy through median sternotomy was analyzed retrospectively in a series of 84 patients operated on for chronic constrictive pericarditis at our institution between 1979 and 1989. The mean duration of symptoms prior to diagnosis was 20 +/- 6 months (1-264 months). Preoperatively, 72% of patients were in NYHA class III or IV, presented signs of right cardiac failure (88%) or anasarca (18%). Chest X-ray showed pericardial calcifications in 40% of the patients. Echocardiography revealed pericardial thickening in 62%. Among 62 patients in whom cardiac catheterization was performed, a characteristic dip-and-plateau was found in 47 patients (76%). A specific etiologic factor was identified in only 37 patients: tuberculosis (12%), recurrent acute pericarditis (9%), hemopericardium (9%), radiotherapy (5%), previous cardiac surgery (4%), bacterial infection (2%), myocardial infarction (2%) and connective tissue disease (2%). In 47 patients (55%), the constrictive pericarditis remained idiopathic. In seven patients we performed a redo-operation for previous incomplete pericardiectomy. Subtotal pericardiectomy (from phrenic nerve to phrenic nerve) was performed in 75 patients. A palliative procedure consisting of pericardial "meshing" was performed in nine patients due to an unsatisfactory cleavage plane. Cardiopulmonary bypass was used in four patients for coexistent cardiac lesions. The operative mortality was 2.3% (two patients: septicemia and pulmonary embolism). Seven patients (8.2%) developed early on-lethal complications. The probability of survival for patients discharged for the hospital was 94% at 3 years and 87% at 7 years. There were four late deaths and no reoperation for recurrent constriction.(ABSTRACT TRUNCATED AT 250 WORDS)

The etiologic spectrum of constrictive pericarditis.

Ninety-five consecutive patients with constrictive pericarditis that was documented at the time of surgery during 1970 to 1985 were reviewed. The etiologies included idiopathic (42%), postradiotherapy (31%), post-cardiac surgery (11%), postinfective (6%), connective tissue disease-related (4%), neoplastic (3%) uremic (2%), and sarcoidosis (1%). Post-cardiac surgery etiology was seen only after 1980, but constituted 29% of cases during 1980-1985. Postradiotherapy etiology occurred with equal incidence in 1980-1985 and in 1970-1980, but the interval from radiotherapy to presentation with constrictive pericarditis was longer in the more recent period (11 vs 4.75 years). Effusive constrictive pericarditis occurred in 24% overall with similar prevalence in all of the etiologic groups except the postsurgical cases, which were caused by noneffusive fibrous constrictive pericarditis in all instances. Operative mortality was 12% overall: It was lower in the idiopathic group (8%) and higher in the postradiotherapy group (21%). Thus postradiotherapy constrictive pericarditis continues to occur despite technical changes aimed at reducing its likelihood, but recent cases have a longer latent period: and postsurgical constrictive pericarditis has emerged as an important etiology.
