Two patients abruptly developed congestive heart failure and elevation in serum transaminase levels when given disopyramide phosphate; enzyme abnormalities and hemodynamic status corrected upon withdrawal of the drug. Both patients had underlying ischemic cardiomyopathy. Myocardial infarction, pulmonary embolism, and viral hepatitis were ruled out in both patients. One patient had a liver biopsy documenting central hepatic necrosis with congestion, consistent with hepatic ischemia and not toxic hepatitis. In the other patient, cardiac decompensation and hepatocellular enzyme elevation were reproduced on rechallenge with the drug. Disopyramide should be used with caution in patients with heart failure.

A fulminant pulmonary embolism can be treated surgically if thrombolytic therapy is contraindicated. A 31-year-old woman developed a fulminant pulmonary embolism after right-sided deep venous thrombosis 1 day after undergoing a cesarean section. A pulmonary embolectomy with cardiopulmonary bypass was performed, but the patient was brain-dead. After 2 days of echocardiographic observation, her heart was explanted for a 61-year-old man with ischemic cardiomyopathy. His right heart data were unremarkable, and he remains well 16 months after transplantation. Despite the sudden strain on the right ventricle that occurs with a pulmonary embolism, such a heart may be transplanted successfully after a pulmonary embolectomy.

Hypotension and shock can be classified as hypotension caused by reduced or maintained left ventricular (LV) ejection. Reduced left ventricular ejection can result from intrinsic left ventricular, aortic valve or mitral valve failure, which includes dilated or ischemic cardiomyopathy, left main trunk disease, acute myocarditis, etc. Acute and subacute severe aortic regurgitation can also cause shock. Echocardiography allows noninvasive diagnosis of infective endocarditis and Takayasu's arteritis to cause severe arotic regurgitation and can also be used to diagnose obstruction of the left ventricular outflow tract. Reduced left ventricular preload can be caused by pericardial effusion and right ventricular ejection failure, and can result from pulmonary embolism, tricuspid regurgitation, right ventricular infarction, tension pneumothorax, hypovolemia and others characterized by a small left ventricle with good ejection fraction. Normal left ventricular ejection may be associated with hypotension. Sepsis, anaphylactic shock and neural disorder are associated with hypotension and normal cardiac output. Pseudohypotension may result from aortic dissection, Takayasu's arteritis, arteriosclerosis obliterans and aortic coarctation. A right parasternal approach enables better visualization of the ascending aorta. Fundamental echochocardiographic scanning allows approximate yet useful diagnosis of hypotension and shock.
