Serpentine Thrombus in Right Atrium: A Tell-Tale Sign of Venous Thromboembolism.

Pulmonary embolism is linked with a remarkable rate of mortality, particularly when it is associated with hemodynamic instability, right atrial thrombus and related right ventricular dysfunction. In patients affected with pulmonary embolism, thrombolysis has been documented to be life-saving. The administration of thrombolytic agents ensures early resolution of the thrombus and prevents arrhythmia and cardiogenic shock. Streptokinase, urokinase and alteplase are among the three thrombolytic agents approved for the treatment of pulmonary embolism. In emergency situations, thrombectomy plays a crucial role.
