Asymptomatic Giant Left Atrium [PDF]
Clinical Cardiology, 2010 AbstractGiant left atria (GLA) is a condition where the left atrial diameter exceeds 65 mm.1 It is closely related to rheumatic mitral valve regurgitation or mixed mitral disease with predominant regurgitation and tends not to occur in patients with mitral regurgitation due to other causes.2 The majority of patients are symptomatic with the most common

Evidence that conflict regarding size of haemodynamic response to interventricular delay optimization of cardiac resynchronization therapy may arise from differences in how atrioventricular delay is kept constant. [PDF]
, 2014 Aims: Whether adjusting interventricular (VV) delay changes haemodynamic efficacy of cardiac resynchronization therapy (CRT) is controversial, with conflicting results.

Spontaneous showering of tumor emboli in a patient with advanced primary lung cancer: a case report [PDF]
, 2012 Extension of primary lung tumors into the left atrium via pulmonary veins is a well-documented phenomenon. Peripheral arterial embolism and cerebral embolism originating from a primary lung neoplasm are rare events. We report a case of simultaneous acute

Giant left atrium calcification [PDF]
Internal and Emergency Medicine, 2015 revealed an unusual pattern of curvilinear cardiac calcification (Fig. 1). Computed tomography showed a giant left atrium with calcification (Fig. 2). Rheumatic heart disease, often neglected by media and policy makers, is a major burden in developing countries. There are about 2.5 million people with rheumatic heart disease in China [1].
