Pulmonary Artery Dilatation Is a Common Finding in a Coronary Artery CT Angiography Population.

Background/aim: Dilatation of the main pulmonary artery (mPA) is a common incidental finding in chest imaging and often leads to consultation. The aim of this study was to determine the prevalence of mPA dilatation in a coronary artery CT angiography (CCTA) population.

Patients And Methods: The study investigated 985 consecutive patients scheduled for diagnostic CCTA.

A smaller heart-aorta-angle associates with ascending aortic dilatation and increases wall shear stress.

Objectives: The aim of this study was to evaluate whether the orientation of the heart, measured as an angle between the long axis of the heart and ascending aorta midline (heart-aorta-angle, HAA), associates with ascending aortic (AA) dilatation. Furthermore, the association between HAA and wall shear stress (WSS) was studied.

Methods: HAA was retrospectively measured in 1000 consecutive coronary artery computed tomographic angiography (CCTA) images in patients with low-to-moderate pretest probability for coronary artery disease (CAD).

High prevalence of ascending aortic dilatation in a consecutive coronary CT angiography patient population.

Objectives: To clarify the prevalence and risk factors of ascending aortic (AA) dilatation according to ESC 2014 guidelines.

Methods: This study included 1000 consecutive patients scheduled for diagnostic coronary artery computed tomographic angiography. AA diameter was retrospectively measured in 3 planes: sinus valsalva, sinotubular junction, and tubular part.
