Primary cardiac tumors involving the heart may be either benign or malignant. Most of the benign tumors are myxomas, which are most commonly located in the left atrium. Primary malignant neoplasms usually involve the myocardium and the interior of the cardiac cavities, whereas neoplasms metastatic to the heart most commonly ...

We report for the first time upon a case of myxoma that involved both atrial and ventricular sides of the anterior mitral valve leaflet. Electron beam tomography (EBT) showed that the tumor was attached to both the atrial and ventricular sides of the mitral valve, while echocardiography did not. EBT ...

BACKGROUND: Despite advances in mechanical and pharmacologic therapy, thrombus-containing lesions are at high risk for adverse events and remain a challenging subset for percutaneous coronary revascularization. Recently, rheolytic thrombectomy with the AngioJet device has been shown to safely remove intracoronary thrombus, but the overall cost-effectiveness of this technique is unknown. ...

OBJECTIVES: This study aimed to determine whether pre-existing angiographic thrombus was associated with adverse in-hospital and six-month outcomes after percutaneous coronary interventions. BACKGROUND: There are conflicting data about whether pre-existing thrombus is an independent predictor of adverse in-hospital and short-term outcome after coronary interventions. METHODS: The Angiographic Trials Pool, a ...

Intravascular and/or intracardiac thrombus formation followed by pulmonary thromboembolism with right ventricular dysfunction immediately after graft reperfusion during orthotopic liver transplantation (OLT) is described in 7 patients.
