Table III. Risk factors for increased diameter of the main pulmonary artery (mPA). The main pulmonary artery size index (mPASI) was determined as the ratio of mPA diameter to body surface area. The PA/AA-ratio was determined as the ratio of mPA diameter and ascending aortic diameter.

AA, Ascending aorta; BAV, bicuspid aortic valve; CAD, coronary artery disease.
