• Distended neck veins
• Postural hypotension
• Mental status changes
• Kussmaul sign: Distention of neck veins with deep inspiration is pathognomonic of pericardial tamponade
• Paradoxic pulse: A fall of > 10 mm Hg with inspiration supports diagnosis
• Equalization of heart chamber pressures with pulmonary artery catheter placement
• Mechanism of injury often raises suspicion
• Decision must sometimes be made for intervention without full confirmation of diagnosis, eg, thrombectomy or pericardial aspiration for penetrating chest injuries and loss of signs of life

• Most common cardiac neoplasm is a metastatic lesion (carcinoma of lung or breast, sarcoma, melanoma)
• 75% of primary cardiac neoplasms are benign (myxoma, rhabdomyoma)
• 75% of benign primary cardiac tumors
• Appearance ranges from smooth, round, firm encapsulated mass to loose conglomeration of gelatinous material
• Most attached to fossa ovalis of left atrial septum; some may occur in right atrium or ventricles
• Histologically, contains various mesenchymal cells
• Papillary fronds attached to aortic valve associated with cerebral and coronary embolization
• Fibromas occur in pediatric patients, slowly invading conduction system
• Presentation depends on type and location of tumor
• Malignant tumors: Rapidly progressive congestive heart failure from valvular or myocardial infiltration
• Myxoma: Fever, weight loss, anemia, systemic embolization
• Mitral stenosis can occur from tumor causing characteristic early diastolic sound "tumor plop"
• Fibromas can cause sudden death from arrhythmias
