Rituximab induced left bundle branch block

Rituximab [a monoclonal antibody directed against CD 20] therapy can be acutely complicated by infusion reactions and cardiac arrhythmia on rare occasions. We report the first case of a new onset left bundle branch block [LBBB] after rituximab therapy for Wegener's vasculitis

Giant interatrial septal aneurysm mimicking a aeft atrial mass

Interatrial septal aneurysm [IASA] consists of redundant atrial septal tissue, which bulges into either the left or the right atrium. The clinical implications of this entity are not entirely clear; however, if it is associated with other cardiac abnormalities such as patent foramen ovale and atrial septal defects. It may assume significance by increasing the risk of cardioembolic events such as stroke. We present a case of an individual with giant IASA detected by transesophageal echocardiography, which was mimicking a left atrial mass on transthoracic echocardiography. This case emphasizes the superiority of transesophageal imaging over transthoracic echocardiography for this clinical entity
