BACKGROUND Cardiovascular and cerebrovascular disease is 2-3 times more common in bipolar patients than the general population. Asymptomatic bipolar patients have electrocardiogram abnormalities at high rates. The question of heart function in asymptomatic bipolar subjects arises. METHODS This study examined the impact of exhaustive exercise on cardiac(More)
The role of TEE in the guidance of cardioversion of atrial fibrillation was studied. Thirty-seven (18%) of 206 patients had left atrial thrombus. Cardioversion was attempted in 153 patients receiving no (n = 107) or < 7 days (n = 46) of anticoagulation prophylaxis, in 27 patients after > or = 3 weeks of anticoagulation, and was cancelled in 26 patients,(More)
BACKGROUND Atrial fibrillation (AF) is widely accepted as a direct cause of cardioembolic stroke from left atrial (LA) thrombus formation. However, the relationship between LA thrombus and transient ischemic attack (TIA) in patients with AF is less well established. METHODS Two hundred sixty-one adult patients (mean age 66 +/- 11 years, 220 men and 41(More)
Two-dimensional transesophageal echocardiographic findings are reported in 13 patients with structurally and functionally normal St. Jude Medical bileaflet mitral valve prostheses. Multiple mobile linear echogenic densities attached to the pivot of the prosthesis were present in 9 of 13 patients. These densities may represent fibrin strands. These mobile(More)
Transesophageal echocardiography (TEE) has advanced rapidly as a valuable cardiovascular diagnostic technique. As the use of TEE increases, so does the importance of well-defined normal cardiac measurements. Presently, few data exist on the accuracy of M-mode TEE-derived measurements. Therefore in 81 adult patients, TEE-derived M-mode measurements were(More)
Patients with obesity tend to have a higher incidence of hypertension, coronary artery disease, and sleep apnea, conditions that could potentially predispose to complications during transesophageal echocardiography (TEE). In addition, patients who are obese are more likely to have oxygen desaturation during upper gastrointestinal endoscopy. However, the(More)
Recurrent thrombosis and pregnancy loss are well-recognized features of the antiphospholipid syndrome. Uncertainty exists, however, as to whether other reported features of the antiphospholipid syndrome such as cardiac valvular vegetations are truly part of this disorder or more reflective of associated systemic lupus erythematosus (SLE). Several recent(More)
The safety of transesophageal echocardiography (TEE) in elderly patients (aged > or = 70 years) and young patients (aged < or = 50 years) was compared in a retrospective study of 283 examinations in each group. A greater percentage of studies was performed in an intensive care unit in the elderly group (22%) as compared with the younger group (13%, p <(More)
Recurrent thrombi, thrombocytopenia, pregnancy loss, and stroke in association with medium to high concentrations of anticardiolipin antibodies are well-recognized features of antiphospholipid syndrome. Cardiac manifestations of primary antiphospholipid syndrome (PAPS) also have been documented but involve structural and valvular heart disease. Diastolic(More)
Two-dimensional transesophageal echocardiography has been shown to be an accurate method of measuring aortic valve area in patients with aortic stenosis. The accuracy of Doppler transesophageal echocardiography for this purpose is unknown. Thus 86 consecutive adult patients (mean age 68 +/- 11 years) with calcific (n = 79) or congenital bicuspid (n = 7) AS(More)
