We studied the hemodynamic effects of surgically induced regional cardiac tamponade in anesthetized dogs. Tamponade restricted to either the right or the left ventricle was compared with tamponade of either ventricle and both atria. Intrapericardial pressures were elevated to approximately 20 mm Hg. With tamponade of the right ventricle alone, aortic pressure rose from 161 +/- 3.8 to 164 +/- 3....

CONTEXT Cardiac tamponade is a state of hemodynamic compromise resulting from cardiac compression by fluid trapped in the pericardial space. The clinical examination may assist in the decision to perform pericardiocentesis in patients with cardiac tamponade diagnosed by echocardiography. OBJECTIVE To systematically review the accuracy of the history, physical examination, and basic diagnostic...

Background. Cardiac tamponade after cardiac surgical procedures is often associated with hemodynamically significant localized pericardial effusions. The localized collection of pericardial effusion in the postoperative period and the atypical presentation of cardiac tamponade limit the use of conventional clinical and echocardiographic signs usually seen with a circumferential pericardial effu...

The relationship of right atrial inversion, a previously undescribed cross-sectional echocardiographic sign, to the presence of cardiac tamponade was examined. We studied 127 patients with moderate or large pericardial effusions. Cardiac tamponade was present in 19 and absent in 104. Four patients with equivocal tamponade were excluded from analysis. Right atrial inversion was present in 19 of ...

We are reporting a case of acute renal failure after cardiac surgery due to acute pericardial effusion. The patient had normal baseline renal function but developed acute oliguric renal failure with a significant increase in serum creatinine postoperatively. Pericardiotomy led to an improvement in blood pressure, immediate diuresis and quick recovery of renal function back to baseline. Pericard...

Cardiac tamponade is associated with decreased cardiac output and increased systemic vascular resistance. Thus, vasodilator drugs might lower systemic resistance and increase cardiac output. Three groups of dogs were studied during tamponade. Group I received nitroprusside only; group II received blood transfusion and then nitroprusside; group III received hydralazine. In group I, nitroprusside...

A 73-year-old man was admitted to the emergency room because of shock and loss of consciousness. Electrocardiography and echocardiography revealed myocardial infarction of the inferoposterior wall and cardiac tamponade. However, laboratory data showed mild inflammation without elevation of any cardiac enzymes. Under percutaneous cardiopulmonary support, coronary angiography showed stenosis of o...

Metastatic malignancy presenting as cardiac tamponade is not uncommon; however, hematogenous spread from carcinoma is rare. There are only three previously reported cases of parotid malignancy with pericardial metastasis. We report a case of parotid adenocarcinoma leading to cardiac tamponade in a 61-year old man. The patient presented with signs and symptoms of cardiac tamponade. The diagnosis...
