Supports risk stratification in giant left atrium; leaves open whether surgical intervention improves outcomes in Level 5 evidence.
Giant left atrium is a condition defined when the left atrial diameter exceeds 60-65 mm. It is commonly associated with mitral valve disease due to excess intracavitary pressure resulting in strain and dilation of the left atrial chamber. The enlarged left atrium leads to expansion of the left atrial volume that leads to the pressure increase in the main bronchus, lung and right ventricle with corresponding cardiopulmonary failure. As giant left atrium is a risk factor of sudden death, its existence merits careful evaluation and surgical intervention.
