Late cardiac tamponade after open-heart surgery.

Late cardiac tamponade occurred in 74 patients 5-287 (median 16) days after open-heart surgery and was treated with pericardiocentesis or surgery. The overall incidence of late cardiac tamponade was 1.3%. After valve operations it was 2.6% and after isolated coronary surgery 0.7% (53/2,028 vs. 18/2,661, p less than 0.002). The diagnosis was assessed by echocardiography in 93% of cases. Pericardiocentesis, attempted in 65 cases (88%), was curative in 80% but failed in 20%. Eight of the latter 13 underwent emergency surgery and five were medically treated. Failure of pericardiocentesis was associated with posterior location of fluid, clots, echo-free space less than 20 mm or myocardial insufficiency. The subxiphoid part of the wound was surgically re-entered in ten cases and the entire sternotomy in seven. Four patients (5%) died within 30 days of the primary intervention. All hospital survivors were observed for a median of 44 (range 11-115) months. Three (4%) had recurrent pericardial effusion requiring repeat pericardiocentesis, but none had pericardial constriction. The 5-year survival rate was 73%.

Cardiac tamponade in rheumatoid arthritis. Successful treatment with intrapericardial steroid administration.

Cardiac tamponade complicated by classic rheumatoid arthritis was markedly alleviated by pericardiocentesis and intrapericardial administration of steroid. For the following 2 years, no recurrence of cardiac tamponade or constrictive pericarditis was observed. According to the literature, only one other patient with cardiac tamponade complicating rheumatoid arthritis (RA) had been successfully treated patient by intrapericardial steroid administration.

Factors associated with increased extravascular lung water in cardiac tamponade and myocardial ischemia.

OBJECTIVE: To evaluate and compare the factors associated with pulmonary edema in cardiac tamponade and myocardial ischemia. DESIGN: Prospective, controlled laboratory study. SETTING: Animal research laboratory of a university hospital. SUBJECTS: Fourteen anesthetized dogs. INTERVENTION: Extravascular lung water (EVLW) was measured with thermal indocyanine green dye double-indicator dilution method and hemodynamic indices were determined by the pulmonary artery flotation catheter. Seven dogs were used in the tamponade model, and seven other dogs were used in the myocardial ischemia model. Furthermore, ten dogs were dedicated to measure plasma colloid osmotic pressure (COP) and blood gas analysis during cardiac tamponade and myocardial ischemia. MEASUREMENTS AND MAIN RESULTS: Mean right atrial pressure (MRAP) (7-->10 mm Hg), pulmonary capillary wedge pressure (PCWP) (10-->13 mm Hg), and EVLW (5.4-->10.1 mL/kg) increased during tamponade, but all of these indices returned to the control level after release of tamponade (MRAP, 7 mm Hg; mean PCWP, 11 mm Hg; mean EVLW, 5.2 mL/kg). Myocardial ischemia caused increases in PCWP (10-->14 mm Hg) and EVLW (5.6-->9.6 mL/kg). Although PCWP returned to the control level, EVLW remained elevated (9.2 mL/kg) after reperfusion. EVLW had good correlations with MRAP (r2 = .64, p < .05) and PCWP (r2 = .62, p < .05) during cardiac tamponade. Despite a fair correlation between EVLW and PCWP during ischemia (r2 = .73, p < .05), EVLW was not related to PCWP after reperfusion. COP decreased during myocardial ischemia and at the reperfusion period, but there was no significant change in COP in the cardiac tamponade model. CONCLUSIONS: In contrast to a close relation between hydrostatic pressure and EVLW in cardiac tamponade, hydrostatic pressure was not a determinant of pulmonary edema during the reperfusion period after myocardial ischemia.

Cardiac tamponade: an unusual clinical presentation.

Pericardial effusion with cardiac tamponade is an unusual presentation of lymphoma, although cardiac involvement is often a late finding in widespread malignancy. Clinical identification can be difficult ante-mortem. New cardiac symptoms or classic findings of cardiac tamponade should prompt aggressive investigation. We present a case of B-cell lymphoma that initially presented as pericardial effusion with tamponade and discuss the characteristic physical findings and radiographic data that assist in diagnosis.

Cardiac tamponade: accurate diagnosis by radionuclide angiography.

This study was performed to define the signs of cardiac tamponade on radionuclide angiography. The first pass studies were performed on a large field gamma camera, using a bolus of technetium pertechnetate. Three hundred and seventy-two studies were analysed. Cardiac tamponade requiring surgical intervention was present at the time in 28 studies. The diagnostic signs of cardiac tamponade on radionuclide angiography were: (1) Right ventricular compression--sensitivity 82%, specificity 97%, predicitive value of a positive result 72%, predictive value of a negative result 99%, and (2) Right atrial compression--sensitivity 21%, specificity 99%, predictive value of a positive result 75%, predictive value of a negative result 94%. Cardiac tamponade can be accurately diagnosed on radionuclide angiography and thus indicate those pericardial effusions which require urgent drainage.

Prognostic role of pericardial fluid cytology in cardiac tamponade associated with non-small cell lung cancer.

BACKGROUND AND STUDY OBJECTIVES: Cardiac tamponade is a life-threatening complication of non-small cell lung cancer (NSCLC). Malignant pericardial effusion signifies advanced disease, but the significance of a negative pericardial fluid cytology in patients with advanced lung cancer is still controversial. The differential diagnosis of cytology-negative pericardial effusion is difficult and sometimes impossible. The purpose of this study is to determine the prognostic role of pericardial fluid cytology in patients with NSCLC and cardiac tamponade. DESIGN: Retrospective review of patients with concurrent NSCLC and cardiac tamponade over a 10-year period. METHODS AND RESULTS: Eighty-two patients were included in this study. Pericardial fluid cytology was positive in 60 patients and negative in 22 patients. The overall median survival was 74.5 days, and 1-year survival was 7.3%, with no survival difference between the two groups (p = 0.2506). However, there was a significant survival difference after different treatment strategies. Patients receiving systemic chemotherapy survived longer than those receiving local therapy (p<0.001), and these patients, in turn, survived longer than those receiving supportive treatment (p<0.001). CONCLUSIONS: When patients have concurrent advanced NSCLC and cardiac tamponade, the most likely cause of the pericardial effusion is the cancer itself, regardless of the results of the cytologic examination. Our results suggest that systemic chemotherapy might prolong survival in such patients, but further prospective, randomized study is necessary.

Management of acute cardiac tamponade by subxiphoid pericardiotomy.

Eighteen patients with cardiac tamponade were treated by subxiphoid pericardiotomy performed with the patients under local anesthesia. This group included 9 cases of uremic pericarditis (50%), 5 cases of metastatic cancer (28%), 2 cases of trauma (11%), 1 case of tuberculosis (5.5%), and 1 case of unknown cause. Immediate relief from acute cardiac tamponade was obtained in all 18 cases with only minor and self-limiting postoperative complications, including transient supraventricular arrhythmias (five cases) and fever (five cases). There were no deaths related to either the operative procedure or reaccumulation of the pericardial effusion. The drainage period averaged 9.6 days (range, three to 28 days). Pericardial biopsy was performed in 15 of 18 cases. We conclude that subxiphoid pericardiotomy is a safe and effective method for the management of pericardial effusion of diverse causes. The ability to perform this technique safely using local anesthesia and the capacity to obtain a biopsy specimen under direct visualization make this technique superior to both needle pericardiocentesis and pericardiectomy in the acutely ill patient.

Reversible cardiac tamponade during prolonged parenteral feeding.

Cardiac tamponade caused by a central catheter is a potentially lethal and infrequent complication. Prompt diagnosis is necessary to decrease the high mortality rate. Cardiac catheterization with a Swan-Ganz catheter and echocardiography can rapidly establish the diagnosis.

Experience with cardiac tamponade following open heart surgery.

Cardiac tamponade following open heart surgery is well described, although, fortunately, uncommon. Unlike more classical "primary" tamponade, the clinical features are not specific, and this can delay diagnosis. In practice, the threshold for investigation must be low, and echocardiography has been invaluable in the detection and localization of pericardial collections. Several factors are believed to contribute to the likelihood of postoperative tamponade, but the mechanisms are not clearly understood. Resternotomy, under general anesthesia, or subxiphoid pericardiotomy, under local or general anesthesia, are effective forms of treatment. However, recent success with the use of percutaneous pericardiocentesis under echocardiographic guidance has shown that postoperative tamponade can be treated safely and effectively by this method.

Coronary artery hemodynamics in conscious dog during cardiac tamponade.

We tested the hypothesis that coronary artery blood flow is sufficient to meet myocardial requirements throughout cardiac tamponade in a conscious euvolemic canine model recovered from surgery. Seven mongrel dogs were chronically instrumented to measure ascending aortic blood flow (electromagnetic flowmeter); intrapericardial, right atrial, and aortic blood pressures; regional myocardial blood flow (radionuclide labelled microspheres); and myocardial consumption of lactate, pyruvate, and oxygen. Data were collected during progressive cardiac tamponade induced by intrapericardial saline infusion to the point of hemodynamic decompensation. Decompensated cardiac tamponade (DCT) was defined as a decline in mean aortic blood pressure to 70% of the level present when the pericardial space was drained of fluid (baseline) and was produced in all animals within 25 minutes. Cardiac tamponade caused a continuous decline in coronary artery blood flow from 1.26 +/- 0.35 (baseline, mean +/- SD) to 0.53 +/- 0.15 ml/min/g (DCT, p less than 0.01), which was associated with a decrease in myocardial oxygen consumption from 1.26 +/- 0.35 (baseline) to 0.74 +/- 0.27 ml/min/g (DCT, p less than 0.05) and a slight increase in myocardial oxygen extraction from 71 +/- 3 (baseline) to 81 +/- 4% (DCT, p less than 0.05). This change in oxygen extraction occurred because of both an increase in arterial and a decrease in coronary venous oxygen content. At all degrees of cardiac tamponade, the lactate-pyruvate ratio did not change significantly from baseline (7.56 +/- 2.31), there was no evidence of lactate production, and the normal endocardial to epicardial blood flow ratio present at baseline (1.41 +/- 0.23) was preserved.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiac tamponade in systemic lupus erythematosus. Report of four cases.

OBJECTIVE: To report and assess the incidence of cardiac tamponade in systemic lupus erythematosus as a cardiac manifestation of the disease. METHODS: We reviewed the medical records of 325 patients diagnosed with systemic lupus erythematosus according to the American Rheumatism Association and their complementary laboratory tests compatible with cardiac tamponade. RESULTS: In the 325 medical records reviewed, we found 108 patients with pericardial effusions corresponding to 33.2% of the total and 54% of the patients studied in the active phase of the disease. Clinical assessment and transthoracic echocardiogram allowed the clinical diagnosis of cardiac tamponade in only 4 (1.23%) patients, 3 of whom were females, white, with ages ranging from 25 to 44 years. The pericardial fluid was hemorrhagic or serosanguineous with high levels of FAN and positivity for LE cells. In the treatment, we successfully used pericardiocentesis associated with high doses of corticosteroids. In clinical and laboratory follow-up performed for a period of 3 years, neither recrudescence of the pericardial effusion nor evolution to constriction occurred. CONCLUSION: Even though rare (1.23%), cardiac tamponade in patients with systemic lupus erythematosus has a benign evolution when properly treated, according to our experience.

Late cardiac tamponade: a potentially lethal complication of open-heart surgery.

Cardiac tamponade occurring late after open-heart surgery is a frequently fatal complication. Of the 13 cases previously reported in the literature, there were seven deaths. In this report, three additional patients with late cardiac tamponade successfully treated are presented. Postoperative anticoagulation with Coumadin appeared to contribute to this complication. Increased awareness of late cardiac tamponade allowing prompt recognition and immediate decompression of the pericardial sac should lower the high mortality rate previously associated with the condition.

Cardiac tamponade complicating leukaemia: immediate chemotherapy or pericardiocentesis?

Although leukaemic infiltration of the pericardium is frequently observed at post-mortem, clinically evident cardiac tamponade is rare. Two cases of cardiac tamponade complicating leukaemia are presented. One patient had cardiac tamponade as the initial presentation of acute lymphoblastic leukaemia and experienced complete resolution of the pericardial effusion within 6 days after chemotherapy without therapeutic pericardiocentesis. The other patient with chronic myeloid leukaemia developed cardiac tamponade requiring pericardiocentesis as the first sign of acute blastic transformation. The roles of early chemotherapy and pericardiocentesis in managing this complication are discussed.

Primary pericardial mesothelioma with cardiac tamponade and distant metastasis: case report.

Although cardiac tamponade is a well-known complication of malignancy, it is uncommon as the initial manifestation. The antemortem diagnosis is difficult and distant metastasis is extremely rare. The presentations of primary pericardial mesothelioma are nonspecific. Pathologically, mesothelioma is the most common in primary tumors of the pericardium. Radical surgery can be used to treat a localized mesothelioma. However, the therapy for advanced primary pericardial mesothelioma is usually palliative because it is resistant to irradiation, and chemotherapy does not markedly improve the outcome. The prognosis is uniformly poor. The median survival from the onset of symptoms is 6 months. We present a 67-year-old woman with cardiac tamponade 4 months prior to a definitive diagnosis of primary pericardial mesothelioma. A computed tomogram confirmed multiple well-enhanced nodules in the pericardium, lungs and liver. Unfortunately, the patient died of multiple organ failure.

Traumatic cardiac tamponade: a heartbreaking tale.

Penetrating cardiac injuries following civil violence are less common in Britain than in other parts of the world, but, in the light of recent evidence, the incidence of the problem is likely to increase. The patient described in this report demonstrates the pitfalls in the management of traumatic cardiac tamponade and highlights the need for a change in the management of the seriously injured patient.

Cardiac tamponade in left ventricular dysfunction.

Echocardiographic and hemodynamic data were measured in closed-chest dogs during graded cardiac tamponade (pericardial pressure 5, 10, and 15 mm Hg) before and after production of diffuse ischemic left ventricular dysfunction. Left ventricular dysfunction was produced by intracoronary injection of nonradioactive microspheres (54 +/- 3.9 mm diameter). Changes in left atrial pressure with cardiac tamponade were influenced by coexisting left ventricular dysfunction. Left atrial pressure increased with tamponade and was equal to pericardial pressure before left ventricular dysfunction was produced. However, after left ventricular dysfunction was produced, left atrial pressure was significantly higher than pericardial pressure before tamponade, but it fell toward pericardial pressure when tamponade was produced. Pulsus paradoxus (greater than 10 mm Hg) was present in all animals with cardiac tamponade before left ventricular dysfunction but in only one animal afterward. During each level of tamponade, the inspiratory fall of aortic systolic pressure was greater before than with left ventricular dysfunction. The slope of the linear regression between pericardial pressure and millimeters of mercury of inspiratory fall in aortic systolic pressure was significantly greater before than with left ventricular dysfunction (0.74 +/- 0.12 versus 0.32 +/- 0.12, p less than 0.05). Left ventricular dysfunction caused a leftward and upward shift of the pericardial pressure-volume relation. As a result, right atrial and ventricular collapse occurred with significantly smaller volumes of pericardial fluid after than before left ventricular dysfunction. We conclude that pulsus paradoxus may be absent in cardiac tamponade with coexisting left ventricular dysfunction and unequal filling pressures. Echocardiographic signs of cardiac tamponade may occur with small effusions in the presence of left ventricular dysfunction.

Pulmonary venous flow in cardiac tamponade: influence of left ventricular dysfunction and the relation to pulsus paradoxus.

The pattern of left atrial filling was studied in nine closed-chest dogs during cardiac tamponade before and after production of microembolic left ventricular dysfunction produced by intracoronary injection of 54 +/- 4 microns (SD) microspheres. With cardiac tamponade, a significant increase in the ratio of systolic/diastolic pulmonary venous flow velocity integral both before (1.65 +/- 0.24 versus 2.77 +/- 0.43 [SE], p less than 0.05) and after production of left ventricular dysfunction (0.57 +/- 0.12 versus 1.77 +/- 0.44, p less than 0.05) was seen. Compared with baseline, cardiac tamponade caused a significant inspiratory decrease in systolic pulmonary venous velocity both before (7.3 +/- 2.0 versus 1.2 +/- 1.4 cm/sec) and after left ventricular dysfunction (3.4 +/- 0.4 versus 1.0 +/- 0.9 cm/sec, both p less than 0.05). The magnitude of respiratory variation (expiration-inspiration) of the pulmonary venous flow velocity integral with tamponade was significantly greater before than after left ventricular dysfunction (1.6 +/- 0.2 cm versus 0.8 +/- 0.2 cm, p less than 0.05). A significant correlation was found between the inspiratory fall in aortic systolic pressure and the flow velocity integral of pulmonary venous flow before left ventricular dysfunction (r = 0.58, p less than 0.05). After coronary embolization, neither pulsus paradoxus nor significant respiratory variation (expiration-inspiration) of the pulmonary venous flow integral was observed with cardiac tamponade. In this model of cardiac tamponade and left ventricular dysfunction, left atrial filling occurs predominantly during ventricular systole. These changes may be helpful in recognizing hemodynamically significant pericardial effusion and have implications for the pathophysiology of cardiac tamponade.
