Does left atrial enlargement on CT chest predict elevated pulmonary capillary wedge pressure in patients undergoing pulmonary hypertension evaluation?
Enlarged left atrial area on chest CT is significantly associated with elevated pulmonary capillary wedge pressure, suggesting it could be a useful non-invasive indicator of left heart dysfunction in patients evaluated for pulmonary hypertension.
