Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]

, 2011
Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...

Left atrial appendage aneurysm [PDF]

Interactive CardioVascular and Thoracic Surgery, 2019
Abstract Left atrial appendage aneurysm is an infrequent abnormality presenting as atrial tachyarrhythmias, progressive dyspnoea, atypical chest pain and systemic thromboembolism. Surgical excision is considered to prevent fatal complications, even in asymptomatic cases. We describe the case of a 44-year-old woman with a history of acute
